Connecting the DPA-1 Connecting to sources and amplifiers The DPA-1 is very simple to hook up. 1. Connect all sources to the DPA-1. Then connect the DPA-1 output signal to a poweramplifier.
Using Main and Line outputs As described in “Routing” and “Crossover Frequency” there are many ways to utilize the Main and Line outputs. Here we have described the three most common set-up´s. Please note the products, outputs and crossover frequencies are chosen randomly in these descriptions. Combine them at your own will and needs. 1. Single-amp set-up with no subwoofer. A poweramp is connected to each Main Output Left and Right. No crossover is selected. Main Output Left No filter Speaker 2.
Menu System The Main Display on the front panel of the DPA-1 shows all functionality and current status of the DPA-1. An overview of the menu tree can be seen in the ‘Menu Tree’ chapter. Navigating the Menu System Pressing the Menu button on the front panel or the remote enters the menu or steps back one level in the menu system. Using the left/right arrows keys the Menu system settings can now be scrolled through. To access a sub menu setting scroll to it and press the Enter button.

Introduction to RoomPerfect™ Once the guided set-up has been successfully completed you have the option to listen to music through two listening settings; Focus 1 and Global room correction filters. The RoomPerfect™ filters are stored on the numerical buttons from 1 to 9 on the remote control. To change from one filter to the other you simply press the numerical button corresponding to the desired filter, or toggle between them by pressing the Up/Down buttons on the remote or front panel.
RoomPerfect™ The sub menus accessible in the RoomPerfect™ menu are: RoomPerfect Guided setup Advanced options Advanced options is only available when Guided set-up has been performed. Guided Setup When you enter the RoomPerfect™ Main Menu for the first time, only the Guided setup is available. Press Enter to initiate the guided set-up.
Setting the Measurement Volume Level The calibration volume is a recommended maximum volume. It is important that you always judge whether the calibration volume is too loud. The calibration volume should not be so loud that it causes: • uncomfortably loud sounds that are inconvenient to you or your environment, or • damage to your loudspeakers. When the message ‘Connect and place mic. in focus pos.’ appears, connect the microphone to the microphone input found on the back panel.
Focus Measurement When the calibration is OK, press Enter to start the measuring process and ‘Measuring Focus position …’ will be displayed. Each measurement comprises four steps: • A low and a high frequency measuring signal first in the left and then in the right channel. The length of each measurement depends on a combination of the measurement volume, set in the calibration process, and the background noise in your local environment.
When a random measuring position and microphone orientation has been chosen press Enter. The measuring process will start and the display will show ‘Measuring room position 1’. The measurement will stop prematurely if an error occurs during the measuring process. In this case, the error message ‘Retry room measurement – press Enter’ is displayed. Press Enter to continue.
Calculation of Focus 1 and Global Filters When RoomPerfect™ calculates the filters the display shows the following, ‘Calculating filters - Please wait’. The filter calculation process can be expected to take anywhere between 5 seconds and a minute depending on the specific task. When RoomPerfect™ has calculated the room correction filters, they are automatically saved. The Focus filter is saved as setting 1 and Global is saved as setting 9 out of the possible 9 filter settings.
Advanced Options This section describes the options in the advanced menu, which is available after Guided Setup has been completed. Here you can add new listening positions and room measurements, check the RoomKnowledge of your current set-up, and check the RoomCorrection for the different filters. Advanced options Measure Focus Pos Measure Room Pos RoomKnowledge RoomCorrection Measure Focus Pos. As mentioned, it is possible to add 7 different listening/focus positions.
‘Add more room meas.? Yes/No’ will show in the display: • choose Yes to add another room measurement or, • choose No to stop adding more room measurements. If No is chosen the volume is returned to the default or lower. ‘Save room measurement(s)? Yes/No’ will hereafter be shown. • choose Yes to save the performed room measurement, • and No to exit without saving any of the performed measurements. Adding one or more room measurements leads to a re-calculation of all filters (i.e.
Display The sub menus accessible in the Display menu are: Display Display Timeout Disp. Brightness Volume Disp.Timeo. Display Timeout Display Timeout set-up is used for enabling/disabling the 10 sec. display ’switch’off’ feature. If enabled the Main Display reading will switch off after 10 sec of inactivity from the remote control or front panel buttons. Disp. Brightness Display Brightness is used to control the brightness of the display. The brightness can be set to 25%, 50%, 75% or 100%.
Volume The sub menus accessible in the Volume menu are: Volume Def. Volume Max. Volume Def. Vol. The Default Volume setting controls the default volume at start-up and can be set from 0 to 99 dB. However, a setting over 88 is not recommended as this corresponds to max output with full scale digital input. Max. Vol. The Maximum Volume setting is a safety precaution used for limiting the maximum volume which can be achieved by spinning the wheel or increasing volume via the remote.
Input Name Input Name As default, digital inputs are called Digital 1-5 and Analog inputs are called Analog 1-4. To change the name, choose an input and then between the following preset names: • ADC, Analog 1-4, AUX, CD, CD-1, CD-2, DAB, DAT, DBS, DCC, Digital 1-5, DVD, DVD-1, DVD-2, FM, LD, MD, PC, PHONO, RADIO, RIAA, SACD, SAT, TAPE, TUNER, TV, VCR, VDP, VIDEO, VIDEO-1, VIDEO-2.
Advanced Setup The sub menus accessible in the Advanced menu are: Advanced setup Communication Main Out Crossover freq Trigger setup Master /Slave Line Out Filter Type Remote Control Digital Out Routing Delay Firmware versions Factory Reset Communication The sub menus accessible in the Communication menu are: Communication Comm Address Comm Speed Comm Address The Communication Address setting identifies the DPA-1’s to the PC interface or other Lyngdorf products.
Main Out The sub menus accessible in the ‘Main Out’ menu are: Main Out Main Out Control Main Out Level Main Out Control The Main Out Control sets the output level to be Full Scale (fixed) or Regulated (variable). Fixed means there’s a constant full scale output – most often used as ‘tape out’ or when using a Lyngdorf Audio TDAI or SDAI as a second ‘slave’ amplifier in a bi-amping set-up. Regulated (variable) means that the output level will follow the level of the volume control.
Routing Routing In Routing it is possible to apply different settings to the Main and Line outputs: Symbol Name Main output Line Output R L Highpass filter X X R L Lowpass filter X X R L L R Left and Right channel switching X - M Mono - X M Mono lowpass filter X A highpass and lowpass filter can be applied to the Main and Line outputs when you want to connect an additional amplifier or subwoofer together with your main loudspeakers.
In general, the recommended crossover frequency between (sub)woofers and main speakers is between 200 - 400 Hz. By using a high crossover frequency, the rear wall quarter wavelength reflection is removed from the main speakers. If a Lyngdorf Audio boundary woofer is used in a 2+2 set-up, a crossover frequency of 400 is recommended due to the high bandwidth of the boundary woofer.
1 centimeter = 0.3937 in The fault message ‘Values for delay exceed limits’ is displayed when the difference between the distance from the speakers closest to, and the speakers furthest from, the listening position is too big. The biggest difference allowed is 340 cm / 134 in.
RoomPerfect™ Troubleshooting No microphone connected The error message ‘No microphone connected’ is displayed when no microphone is connected to the DPA-1. Solution: • Connect the microphone on input on the back panel. No signal 1. The error message ‘Fault – No signal’ is displayed when the incoming signal is classified as pure noise. This happens when the measuring signal is too low compared with the noise from the local environment.
Firmware Upgrading The DPA-1 firmware can be upgraded using the ‘Lyngdorf Audio – Serial Load’ software. This is in the PC package available from www.Lyngdorf.com. Follow the upgrade steps shown below to bring the product into upgrade mode.
