Section 1 PX-700 Product Description Description The PX-700 Multi-Room Controller is a six zone, multi-room, multi-source audio system controller that is easily set up with Audioaccess Installation Manager, Audioaccess’ proprietary Windows® application. Installation Manager will program all the functions of a PX-700 installation including the configuration settings of the MA-361 Twelve Channel Digital Amplifier and the VX-241 Video Matrix Switcher.
PRODUCT DESCRIPTION Installation Manager uses standard control features found in all Windows applications: right mouse clicks, drag and drop, and pop up menus. Diagnostic tools are included to monitor RS-485 bus communications. Other tools include an Equipment List, Wiring Instructions, and a complete on-line Help file.
PRODUCT DESCRIPTION Front Panel SYSTEM CODE SWITCH (Momentary switch accessible through panel) LED (Bi-color: red when power is applied, green when any zone is on) The front panel LED on the PX-700 indicates that the unit has power and that at least one Zone is on in the System. If the LED is on (in any color), the unit is powered. If the LED is red, no Zones are on in that System. If the LED is green, at least one Zone is on in the System. When you first apply power to the PX-700 the LED will be red.

Section 2 Quick-Start Guide You Will Need ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ Beginning the Installation • Design the Installation with your client. Determine the source equipment for the Installation and the way the Installation will work in each room. Completing the Installation • Wire the Installation. • Connect the PX-700s to each other. • Test the Installation. You can test the operation manually from the keypads or remotes, or by using the Virtual Installation in the tools menu.
QUICK START GUIDE ☞ The following three conventions apply to Zone and Room definitions: Zone A Zone is an area of an Installation that accesses a source independently from another Zone. A Zone contains a Primary Room and up to three Expansion Rooms. Each Room within a Zone has independent ON/OFF and Volume control. There are six Zones available to each PX-700 in an Installation.
QUICK START GUIDE The PX-700 must be very well ventilated. Be sure to provide for this when installing each unit and in designing of any cabinetry for the Installation. Provide ample space for air circulation and flow-through ventilation around all the other electronics too, especially amplifiers. Allow room for growth of the system. Whenever possible, allow for access to the back of the equipment.

QUICK START GUIDE Audio 2.6 ➤ To connect audio sources, use regular RCA cables to connect sources to the left and right SOURCE IN jacks on the rear panel of the first PX-700. With additional RCA cables, connect the SOURCE OUT jacks to the SOURCE IN jacks of the next PX-700. Cascade the Source In and Out in this manner until you have connected all the PX-700s.
QUICK START GUIDE Paging ➤ IR ➤ Trigger Out and Switched Outlet ➤ To connect a Page/Doorbell Module to a multi PX-700 system, parallel the Mute Out from the PDM to the Page Trigger of each PX-700. To parallel the Page Trigger, use a two-way 1/8" mono mini plug splitter or "Y" adapter (available at most electronic supply shops) and an extra mini plug to mini plug cable to connect each additional PX-700. Connect the Page Audio output from the PDM to the Page In.

Section 3 Physical Installation Source Equipment AC Power Use the Switched Outlet to provide power to source equipment whenever possible, because the PX-700 needs to power up equipment in a known state when the Audioaccess Installation comes on. In addition, when the source equipment is shared with another audio system, the PX-700 needs to control the equipment status so that it does not stop transports or power off equipment in use by the other audio system (refer to Switched Outlet on page 3.14).
PHYSICAL INSTALLATION on the power conductors due to the wire resistance and the current consumption of the connected device. Heavier wire will have lower resistance, therefore the longer the wire run, the lower the wire gauge. As a rule of thumb, use 24AWG up to 250 feet, 22AWG up to 500 feet and 20AWG up to 1,000 feet. 5. For the ATC, see the section on “Length of ATC Cable Runs” (page 3.6) for the formula to calculate cable runs.
PHYSICAL INSTALLATION Avoid splices. This will save time and prevent problems in general. However, if you must splice a cable, do not bury the splice! Make sure it will be accessible after the walls are finished, or re-run the cable. When making “trunks” of cables (several cables groups going in the same direction for a long distance), keep wires with like signals together. Especially be sure that speaker cables, which carry relatively high current, are kept away from audio and data cables.
PHYSICAL INSTALLATION In multiple PX-700 Installations, each PX-700 in the Installation should have a dedicated KPT so that the keypads are not all powered from the same unit (see Examples A and B on pages 2.4–2.5). KPS Wiring The wiring code (Power, Data 1, Data 2, and Ground) is shown on both the back plate of each keypad and on the rear panel of the PX-700. Some keypads have a color code on the back plate that you may choose to follow.
RXD + Data 2 RXD – Data 1 Power Ground TXD + TXD – PHYSICAL INSTALLATION 8 7 6 5 4 3 2 1 Front Top Ca t5 C able C t a 5 ble Ca 4. Connect the Cat 5 cable to the ATC RS-232 Interface Board and the rear of the ATC. 5. Run 4-conductor wire from the keypad connector on the ATC RS-232 Interface Board to the appropriate keypad connector on a KPT. ☞ IMPORTANT NOTE: The PX-700 is designed to power up to 20 KPS keypads at 50mA each (to a total of 1A).
PHYSICAL INSTALLATION Length of ATC ➤ Cable Runs The resistance of the cable and the voltage of the power supply to the ATC determine the maximum cable length. The ATC requires a minimum of 8VDC at the ATC. The PX-700 supplies 10VDC from the RS-485 bus. This means that up to 2 volts can be dropped due to the resistance of the cable.
PHYSICAL INSTALLATION At the ATC RS-232 Interface Board Method 1 (preferred) Use this method when powering the ATC from an AC to DC adapter. 1. Make a pigtail with a short length of Cat 5 and an RJ-45 8 pin connector. 2. Splice this to the 4-conductor cable, connecting only power (pin 3), ground (pin 6) and RS-485 + /data 1 (pin 5) and RS-485 – /data 2 (pin 4). 3. Connect to Interface Board. Method 2 Connect directly to KPT, using the same cable run formula as for Cat 5 cable above.
PHYSICAL INSTALLATION Audioaccess remote controllers and decode them at the keypad. Control data is then sent to the PX-700. No actual IR signal is transmitted to the PX-700 from the keypad. ☞ NOTE: If a repeater is needed, plan for the addition of a separate IR repeater next to the keypad or somewhere conveniently located in the room! For KPS keypads installed outside or in bright rooms, turn off the IR receiver on the keypad. Set DIP switch #9 on the keypad in the UP position.
PHYSICAL INSTALLATION System Switches For a single PX-700 Installation, the System Code should be set to “1” (switch 5 up). In a multi PX-700 system, the System Code on the keypads must be set to the System Code of the corresponding PX-700. The System Code switches have these values: switch 5=1, switch 6=2, and switch 7=4. Add these values together to get totals equal to the System numbers. Consult the Wiring Instructions for specific information on each Project.
PHYSICAL INSTALLATION DIP Switch Settings for IR Switch #9 controls the keypad IR receiver. In the “down” position it is ON, in the “up” position it is OFF. When a keypad is mounted outdoors, in a bright, sunny room or within 4" of a manually operated light dimmer, the IR receiver should be turned off. DIP Switch Settings for Terminator Switch #10 controls the terminator. This switch adds 1K ohm impedance across the two data lines. Keypads are shipped with the terminator switch in the “up” or OFF position.
PHYSICAL INSTALLATION Expansion Outputs (Fixed) These are secondary, fixed, unity gain outputs for each Zone which are specifically designed for connection to an MA-361 Twelve Channel Digital Amplifier with up to six EM-401 Volume/Tone Control Modules or a PX-603 Multi-Room Expander. Up to three Expansion Rooms may be added to any Zone. Expansion Outputs may also be used as fixed outputs to an amp that powers speakers through passive attenuators (autoformers).
PHYSICAL INSTALLATION The factory default for the ALL output is as an emitter. To connect a blaster-type IR emitter to the ALL jack do the following: ➤ Disconnect the AC power cord from the PX-700 ➤ Remove the top cover of the PX-700. ➤ Find a small jumper with the words “FLASHER” and “BLASTER” on the IR Output board, directly in front of the ALL jack at the right end of the PCB. ➤ Remove the shorting plug and place on the side marked “BLASTER”. ➤ Replace the cover.
PHYSICAL INSTALLATION ➤ If the trigger is active when the last Zone is turned off, the PX-700 will not execute the Last Zone Off macro. ➤ If no Zones are on in the PX-700 Installation when the Trigger In voltage is removed, the PX-700 executes the Last Zone Off macro. Trigger Out The PX-700 supplies the Trigger Out with approximately 12 VDC and, in its default state, is active whenever any Zone in the Installation comes on.
PHYSICAL INSTALLATION RS-232 Port This port enables direct connection of other RS-232 command systems to the PX-700 or connection to a PC for IR and system programming. The programming port is replicated with a mini-jack on the front panel. When the front panel PC Link is in use, the rear panel connector is inactive. Switched Outlet This outlet powers up when the first Zone is turned on, and off when the last Zone is turned off according to the programming of the Trigger Out in Installation Manager.
Section 4 System Operation The Audioaccess keypads, touchscreens and IR remote controllers are an integral part of a PX-700 system. They are, largely, the whole system from your clients’ point of view. The following is a broad description of the operation of a PX-700 system from a KPS keypad or IR remote.
