Delta Series Audio Controllers Delta Series Audio Controllers Overview The Delta Series Audio Controller is an affordable, feature-rich multi-zone audio distribution system that allows control and distribution of audio from 4 sources and to 4 or 6 zones. The DAS-D0404 controls of up 4 sources and distributes audio to 4 rooms/zones. The DAS-D0406 controls of up 4 sources and distributes audio to 6 rooms/zones.
Delta Series Audio Controllers Delta Series Product Specifications (Cont.) • LCD Display Screen Displays information necessary during the programming steps and afterward is the display to indicate information about the source input and zone activity. Rear Panel Components: • Power Switch & Receptacle The master power switch will remain in the ON position normally. • AM/FM Antenna Inputs Connections for the AM and FM Antennas. • IR Outputs (4) Four 3.5mm IR Emitter Output Jacks.
Delta Installation - Quick Start Steps Delta Installation - Quick Start Steps 1. Connect the Source Units to Delta Plug RCA audio cables from each source device into the labeled RCA jacks at the back of the Delta Controller. Ensure that right and left are connected correctly. Then connect the IR emitter leads for each audio source into the appropriate connector on the back of the Delta Controller and run the optical end of the emitter lead to the source device’s IR receiver window.
Delta Installation - Quick Start Steps 2. Connect the Keypads to Delta Looking at the rear of the keypad with the connectors at the bottom, you will see (2) plug type 4 pin receptacles. The connector on the right side terminates the 4 conductor wire from the Delta Controller and the connector on the left side passes the audio to the speakers in the zone (FIG. 2).
Delta Installation - Quick Start Steps 4. Power Up and Test the Basic System Operation Make sure the Delta Controller is plugged into the wall and the power switch on the back panel is in the ON position. The Delta system should now be ready for initial testing. To test the system connections, activate one source from a keypad.
Delta Installation - Quick Start Steps Tone Control The tone control mode allows the user to adjust Bass, Treble, and Balance on a “per zone” basis. To enter tone control mode, press VOL UP & VOL DOWN buttons simultaneously until LED’s begin to cycle in a counter-clockwise motion. This will enable the BASS and BALANCE settings first. At any time during adjustments, If you want to return the settings to default, press and hold the centre keypad navigation button.
Wiring and Connections Wiring and Connections Pre-Installation Precautions and Recommendations The Matrix Delta system is extremely flexible. It can be installed in a number of configurations depending on your audio needs. The capacity of a single unit is 6 independent zones and is typically wired with at least one keypad located in each zone. In some cases it is desirable to operate a second set of speakers within the same zone controlled by the same keypad.
Wiring and Connections Cable Type The Delta Controller is cabled using standard 4-conductor speaker cable originating at the Delta control unit passing through the keypad and terminating at the speaker location. Matrix Audio Designs generally recommends using a bundled 4 conductor 16 gauge stranded copper wire in a single continuous run. The keypads also function with Cat 5 or basically any 2 conductor wire configuration that is not used for other devices.
Wiring and Connections Considerations for Existing Construction For existing construction, successful implementation can be achieved by using retrofit electrical boxes that do not require stud mounting or metal electrical frames which are commonly used for telephone and cable installations. These “afterthought” low voltage electrical boxes can be placed in a standard opening in the wall.
Wiring and Connections Considerations for Outdoor Zones Outdoor listening zone locations present some unique challenges, both for the wiring and for the control keypad placement. Outdoor Wiring Special care should be taken when cables transit outside the structure. External cabling should run through conduit (plastic electrical conduit works well) to protect it from the elements and small animals that may wish to chew on the cable.
Wiring and Connections FIG. 5 Source Unit to Controller Connections Source Input #1 is left open because the default is the internal AM/FM tuner. The Delta Controller learns the IR commands for power on/off during the programming setup. Source components are turned on when they are selected on the keypad. The source remains on until it has been idle in all zones for a duration of 10 minutes, then Delta will automatically turn it off until it is selected again.
Wiring and Connections Depending on the installation location, it may be necessary to use a powered FM antenna to receive clear FM stations. When an AM/FM tuner has been installed, input #1 will default to the internal tuner and the RCA input jacks will not be active for source #1. If no internal tuner is installed, the source #1 inputs will be active. Either way, Source#1 is activated by the top-left button on the keypads. Source #2 is activated by the top-right button on the keypads.
Wiring and Connections Standard 4 Wire Keypad Connections The standard installation of keypads to the Delta Controller is with 4 wires directly between the Controller’s zone output and the keypad’s input (right side connector of the keypad), as shown in FIG. 7. FIG. 7 Standard 4 Wire Keypad Connections If the building was “pre-wired” for standard audio, this is the configuration they most likely intended. If you wired (or will wire) the keypad locations yourself, this is the most common configuration.
Wiring and Connections 2 Wire Keypad Connections (Control Only) In some retrofit configurations it is not feasible or possible to re-route the speaker cable through the keypad. In cases such as this, it is possible to run a separate cable pair (CAT- 3 / CAT- 5 / CAT- 6 / Twisted Pair / Other 2 conductor wiring) cable from the Delta Controller to the keypad device for control purposes.
Wiring and Connections Multiple Keypads in a Zone Certain situations such as large rooms or rooms with more than one common entrance may require more than one keypad control to conveniently manage the zone. This configuration allows for 2 Matrix keypads to be placed on the control circuit. Make sure that the second (AUX) keypad has the wire loop cut so that it’s addressed to the Delta Controller as an auxiliary keypad, rather than a “MAIN” keypad (FIG. 9). Secondary Keypad wiring Main Keypad wiring FIG.
Wiring and Connections Matrix Keypad plus Analog Volume Controls In cases of split zones where more than one set of speakers are driven from the same zone output (such as a master bath off of the master bedroom) it is sometimes desirable to place independent volume controls in the split zones while retaining the Delta Keypad for source control and ON/OFF functions. FIG. 10 shows the connections to a remote zone and “Autoformer” volume control devices.
Wiring and Connections Auxiliary Amplifier Configuration (Zone 1) In some cases you may require more power for a given zone than the Delta Controller can provide. FIG. 11 shows how to utilize the preamp RCA outputs on the Delta Controller for an external amplifier. This may be useful when outdoor or large rooms make up the zone, or in situations where the number of speakers will require a multi-channel amplifier to safely power them all. FIG.
Wiring and Connections Auxiliary Amplifier Configuration (Zones 2-6) In cases where you require more power for a given zone than the Delta Controller can provide and it is other than in Zone 1, use this diagram. It shows use of a Matrix LLC device designed to reduce the “speaker level” output of the Delta Controller to “line level” so that it can drive an auxiliary amplifier. This amplifier would typically be installed at the equipment rack (source end).
Wiring and Connections Connecting the RS-232 Serial Port Delta Audio Controllers provide an RS-232 (DB9) port for receiving RS-232 Controller Commands. Refer to the RS-232 Controller Command Messages section on page 55 for a complete listing of supported commands.
Wiring and Connections Wiring TO the speakers in the zone connects here Wiring FROM the Delta Controller connects here Match the color/position of the wiring at the Keypad with the wiring at the Controller FIG. 13 Orientation of Connectors Preparing the Wires When working with the SWT connector, only strip away about 1/4” inch (about 6mm) of the insulation from each wire.
Wiring and Connections Installation into the Wall Cavity 1. After wiring is complete, simply push the wiring back into the wall cavity and make sure there is enough room for the Matrix keypad to comfortably fit into the opening. Do not force the keypad up against wiring or other obstructions if it cannot fit flush to the mounting holes because damage can occur to the circuit board of the keypad. 2.
Wiring and Connections Connecting Matrix In-Ceiling Speakers Overview - Speaker Wire Technology (SWT) Speaker Wire Technology (SWT) allows both data and audio signals to travel over the same four conductor wire. This is the same four conductors that you would run (or is run) in your home wiring installation for a standard speaker and volume control installation. This remarkable technology removes the need for control wire since the control and audio signals are shared on the same wire.
Wiring and Connections FIG. 16 Wiring Matrix Active Speakers - Method A Method B (Retrofit) In the configuration illustrated in FIG. 17 (typical in retrofit applications where wiring is in place), each speaker has a 2 wire feed and a “4 wire bridge” connection must be installed between the two so that the active (4 terminal) speaker can receive a full 4 wire input (using 2 of the 4 wires) and then bring audio back to the second speaker through the remaining 2 wires.

Programming the Delta System Programming the Delta System Overview Programming and IR Capture take place on the front panel of the Delta Controller. Settings such as Bass, Treble, and Balance functions are programmed from within any zone using the keypad. We suggest you read this section carefully in its entirety BEFORE starting to program the Delta Controller. This will allow you to obtain a general understanding of what you will see and what to expect when you go through the programming exercise.
Programming the Delta System FIG.
Programming the Delta System Accommodating Multiple Device Programming Programming is an interactive exercise between you, the Delta Controller and the audio source remote control, which may vary from unit to unit. You will learn the techniques to best train the Delta Controller through some trial and error and observation. The audio source remote should be located about 6-12 inches away from the IR receiver on the Delta Controller.
Programming the Delta System Program Menu Selections Setup is where the user will program Sources, access Tuner and Clock information. Preferences allow user to set up preferences for Backlight and Display Options. About displays the Version # for the Controller firmware. Each of these program menu selections is detailed in the subsequent pages of this section. In screens with multiple lines of selections, an arrow is used to indicate which line of information is currently active (FIG. 20). FIG.
Programming the Delta System Selecting Clock (FIG. 23) will allow the user to set the Clock Time/Date/Day for the System. FIG. 23 Setup Menu - Clock Selecting Exit exits to the Main Menu (FIG. 24). FIG. 24 Setup Menu - Exit Controller Sub Menu Programming Source Components 1. From the Setup screen, select Controller. The Controller Setup screen will be displayed.

Programming the Delta System Learning IR Commands Before programming any remote commands into Delta, make sure you understand the button labels that Delta assigns a source component’s IR commands based on the “source type” as shown on the previous pages. When the “Learn IR” screen asks for a command, use the exact command from the remote. Use the exact sequence that you normally would to turn on the source component.
Programming the Delta System Label allows customization of the labels for the IR commands that relate to the keypad navigation buttons: UP/DOWN/LEFT/RIGHT/ CENTER (USER DEF1) / CENTER HOLD (USER DEF2). Some commands cannot be relabeled. Quit returns user to Select Source for Programming screen. When an IR command is taught to Delta, there is an indication that appears on the Controller screen with an option to test the command. This message indicates the success (or failure) of the command learning.
Programming the Delta System IR FULL (All memory for storing IR codes has been used). Pressing [OK] returns the user to the same IR command to be re-learned (FIG. 32). FIG. 32 IR FULL If a command is NOT learned, i.e. IR FULL, IR not taught…, IR 0 percent sure, clicking OK will return the user to the same IR command so that it can be re-learned.
Programming the Delta System FIG. 34 Label Selection When Label is selected, the first letter in the IR command label will begin flashing (FIG. 35): FIG.
Programming the Delta System Adding Delay to IR Commands On the Select Source Type screen, users have the option to add a “delay” to each IR command learned for the specified source (FIG. 36). A delay is sometimes necessary when the preceding remote command has an extended string or if it takes a small amount of time to “process” the command before the next one is recognized. When Delay is selected, the Delay Programming screen is displayed, with .2 sec as the default delay.
Programming the Delta System FIG. 37 Labeling a Source Labeling a Room Any room can be named whatever the user wants (within the character selections) but is limited to 6 characters per zone. To label a room, select Room Label and which of the rooms you want to label. The first letter will begin flashing. If you choose not to label a room and delete all the characters so only blank spaces appear, when the room is activated there will be no text label shown on the Delta Controller front panel.
Programming the Delta System FIG. 38 Labeling a Room To label a room, select “Room Label” and which of the rooms you want to label. Since the screen defaults to “Exit”, use the navigation buttons to navigate the rooms on the menu and when you want to select one to label, press the center navigation button. The first letter will begin flashing. In the example shown in FIG. 39, the label for Zone #1 is being selected for labeling.
Programming the Delta System Begin labeling the room using the same method as the IR command and source programming from previous pages, selecting the center button to move to the next character. If the room has not already been labeled or defined, RM1-RM6 will be displayed for each zone. Any room can be named whatever the user wants (within the character selections) but is limited to 6 characters per zone.
Programming the Delta System The user can select a room by using Nav RIGHT/LEFT and Nav. CENTER to select a room. Selecting a room will take the user to the Status Screen for that room. The default is Room 1. If there is no Main keypad or Aux keypad, Keypad not Resp. will be displayed instead of Main keypad Vers # or Aux Keypad Vers #.
Programming the Delta System Tuner Sub Menu From the Setup screen, select Tuner (FIG. 42). If there are no tuner modules installed in the Delta Controller, the Tuner selection will simply not appear. You can select the band (AM/FM) - The AM/FM selection works like a toggle. Select AM and press Nav. Centre, it will change to FM. Press Nav. Centre again, and it changes back to AM.

Programming the Delta System FIG. 47 Display Menu If Room is selected (this is the default), the “M” will be displayed, along with any zones that are turned ON. It will only show active zones and, if the zone has been customized with a label, it will display that label. When all zones are off, it simply defaults to the “M” screen. If Clock is selected, the current time, date, and day will be displayed (the “M” will not be displayed - FIG. 48). FIG.
Programming the Delta System user to the “Main Menu”. When exiting the Main menu, the Tuner Information will be displayed once again. If none of the zones/rooms are ON, then the “M” will be displayed. When a zone is turned on to the tuner, the Tuner information will be displayed. The Tuner information consists of the Preset Number (if applicable), the station frequency, AM or FM, and Stereo or Mono.
Using Matrix Keypads Using Matrix Keypads Using the Matrix KP-4e Keypad Source Selection The Source Selection Key is different than the other function keys. It provides control of the Source On/Off, System On/Off and Play/Pause. When a source button is selected, the following occurs: The SOURCE is turned ON & begins playing. If source = on-board TUNER, the last station listened to will begin playing. If source = external TUNER, the last station listened to will begin playing.
Using Matrix Keypads All Zones ON or OFF To turn ALL zones ON to the same source, press and hold the source button for 4 seconds. To turn that source back OFF in all zones, repeat the process by pressing and holding the active source button for 4 seconds (FIG. 52). Press and hold (top 2 sources) for ALL OFF FIG. 52 All Zones ON or OFF To turn ALL zones OFF and shut the whole Delta system down, press and hold Source button 1 & 2 (top 2 buttons) simultaneously for 4 seconds.
Using Matrix Keypads Volume Control Control of the system volume is very intuitive because of discrete buttons for the Volume UP and Volume DOWN command (FIG. 54). Volume Keys FIG. 54 Volume Control When increasing or decreasing volume, the progression is in 3dB steps when the volume is half (of maximum) or below. Above the halfway point, the progression drops to 1dB steps so you can fine tune the adjustment without worry of overdriving speakers by surprise.
Using Matrix Keypads Bass (and Balance) Adjustment Bass and Balance Adjustment Mode is the first action taken during the setup sequence. The source indicator lights will rotate in a counter-clockwise direction indicating Bass Adjust Mode. Click the navigation button in the up direction to increase the Bass and down to decrease the Bass (FIG. 55). Use keypad to adjust Use Vol+ and Vol- to begin settings FIG. 55 Bass/Treble (and Balance) Adjustment Bass adjustments are +/- 10 dB, moving in 1dB steps.
Using Matrix Keypads Using the Matrix KP-NUM Keypad There are several “advanced” functions that are associated with the KP-NUM keypad (FIG. 56). These functions use the “0 through 9” plus the “Star” or “Dot” and “Enter” buttons. FIG. 56 KP-NUM keypad This numeric keypad allows for the use or programming of presets as well as Direct Numeric Access for AM/FM stations, Multi Disc Changers, or other source components that have a numeric keypad on the original remote control.
Using Matrix Keypads Direct Numeric Access - CD Player or Changer When selecting direct numeric access for a single disc CD player, the format is ONLY to choose the track (since there is only a single disc from which to choose). When selecting just a track the Delta Controller will recognize a selection of up to 3 characters (1-999).
Using Matrix Keypads FIG. 60 Direct Numeric Access - Satellite Radio or DSS/DBS Tuner Setting Individual Source Component Presets The numbers on the numeric keypad (1-0) can be used to store presets for each source. Each source has 10 possible presets. The presets are source specific and NOT room specific.
Using Matrix Keypads In the examples shown in FIG. 61, the source is first selected, then the channel, station, or track number is entered for bring up the preset you would like to save. Once the selection is playing, press the “dot/preset” button and the numbered position you want and Delta stores the preset when you press and hold ENTER. To recall that same preset on the same source, simply press the “dot/ preset” button and the numbered position you want then ENTER. FIG.
Using Matrix Keypads Using the Matrix Touch Panel Keypad The Matrix touch panel keypads (FIG. 62) have a unique, touch sensitive LCD panel that has 12 individual “grids” (also called “touch fields”) that become different command buttons depending on what source and previous command was selected. It’s really the best of a KP-4e and numeric keypad all in a single unit, yet with even more customizable features as well as visual user feedback. FIG.
Using Matrix Keypads The above customized field labels are stored on the Delta Controller so that it can be shared with other LCD keypads, the Network Interface application, or anyone using RS-232 commands to control the Delta Controller. Customizing LCD Keypad Labels Customization of labels displayed on the LCD keypad is done via the Setup menu on the front of the Controller. Both Source labels and Source Control labels can be customized (FIG. 64). Source Labels Source Control Labels FIG.

Troubleshooting Troubleshooting Overview If you are reading this section, it’s likely that something has gone wrong. You have installed the Delta system and tried to program but something just doesn’t seem to be working right, or it’s not working at all. Try working your way through this troubleshooting section to help isolate the problem. Before Delta units leave the factory they are “burned in” and extensively tested to ensure proper operation.
Troubleshooting the LED does not light with a keypad press, then it is possible that the device has not been programmed. If the LED does light, there may be a problem with the IR emitter lead. When testing IR problems, it is helpful to carry a blinking emitter or a test emitter to ensure that the commands are being sent to the source.
