Inputs and Outputs

Each input and output channel uses a triplet Phoenix connector. For details on connecting inputs and
outputs, see page 21-23.
Inputs can be any line level source, such as musical instruments, microphones (preamplified to line
level), tape players, CD players, etc. Input connections are made to the blocks on the left of the
Matrix unit. The input plugs must be connected in ascending numerical order, from left to right, as
printed on the Matrix.
Outputs are wired to monitor amplifiers (headphone, floor wedge etc.) Output connections are made to the
blocks on the right hand side of the Matrix unit. The output plugs must be connected in ascending numerical
order, from left to right, as printed on the Matrix.
Each output is associated with a single Mini-Mixer. For example, the Mini-Mixer at address 03 may
control a pair of headphones connected to output number 3. The Mini-Mixer at address 10 may
control a monitor speaker connected to output 10. Stereo (2 output) Mini-Mixers use two consecu-
tive matrix outputs. (see Mini-Mixer location selector on page 18 for more information on stereo
pairing).

DIP Switch Settings

The DIP switches are the set of eight small toggle switches next to the Reset LED on the rear panel.
These switches define the mode of the central processor of the matrix system. They are set at the
factory and generally should not be adjusted. (Normally all switches are down.)
Baud Rate
DIP switches 5 and 6 control the baud rate between the RS232 control port and an external control-
ler. Note that this does not control the rate of communication between the matrix and the Psycholo-
gist remotes.
Checksum
DIP switch number 7 controls the activity of the checksum and escape byte function in RS232
communication. If the switch is in the up position, escape and checksum are used. If the switch is
down escape byte and checksum are not used. Intelix recommends using escape byte and checksum
in applications where RS232 communication may be hindered due to cable length (a maximum of 50 feet)
or lack of shielding from external electronic noise. Escape byte and checksum should be turned off (switch
