Mini-Mixer Connections

The Psychologist system uses a parallel wiring scheme to communicate bi-directionally with the Mini-Mixer
remote controls. The Mini-Mixers connect to the PPS-12 power adapter and each other with Intelix PC
cables, female to female 9 pin. Total cable length may not exceed 3000 ft. If using a daisy chain
configuration, you will use both DB9 connectors on each remote except the last one in the chain. The ports
are interchangeable so either port can serve as the input or output. If using a star configuration, you will only
use one of the DB9 ports on each mixer. It does not matter which one. You can use both configurations
together in the same system.
Follow the steps below to connect the Mini-Mixers to rest of the Psychologist system. Refer to drawing on
page 25.
1. Intelix strongly recommends that the PPS-12 is installed as close to the Mini-Mixer remote
locations as possible. If the Psychologist matrix is installed in a rack room away from the stage/studio
location, it may be necessary to run a length of Cat 5 UTP cable to the stage/studio location for connection
to the PRJ12/DB9F adapter. Intelix supplies an 18" cable, RCRJ12-18, for close proximity installations.
Connect the PRJ12/DB9F adapter to the PPS-12 adapter. Plug the RCRJ12-18 cable into the PRJ12/
DB9F adapter and the ReO port on the rear of the matrix.
2. Plug in the PPS-12 power supply. Note: Larger systems may require more than 1 PPS-12 power supply
module. Refer to the chart on p.18 of this manual for more information. If 2 PPS-12 power supplies are
required in a daisy chain configuration, they should be placed at opposite ends of the chain.
If 3 PPS-12 supplies or more are required, they should be evenly spaced in the Mini-Mixer chain. Only
DC power supplies can be connected in parallel!
3. Connect the first Mini-Mixer, which should be set at station/output 01 using the rotary switches, with the
desired length of PC cable. Watch the LED, located near the Master level control. The LED will blink once
every 2 seconds, for up to 30 seconds, and then it will turn on steady. When this occurs, the matrix has
recognized the remote. You can then repeat this procedure for all of the remotes in your system in order of
their station/output numbers. If you encounter any problems while performing this procedure, it is best to
clear the matrix memory and start the procedure over. (See Reset the Matrix Memory on p.15) Otherwise
station conflicts may occur.
Once the Mini-Mixers have been recognized by the matrix, their station/output is stored in its internal
memory. You can then move them to any physical location that you wish. However, they will always control
the station/output for which they are assigned. Do not change the remote station/output settings once
they are installed. The new settings will conflict with the settings already stored in the matrix
memory. If you need to reconfigure the system it is better to clear the matrix memory and start the
remote installation procedure over.
