LAYOUT DESCRIPTION
The layout given in the following pages is meant to be con-
nected to a PC by a parallel port (printer) cable. The board is
controlled by software for a Windows PC. The parallel cable
must be the standard type used for hooking up a printer to a
PC: one end is a DB-25 connector andthe other is a 36 pin
Centronics connector.
Banana connections are provided for V
, ground, and am-
plifier outputs. Amplifier outputs are also routed to a stereo
headphone jack. RCA connections are provided for amplifier
inputs, loop in, loop out, and microphone out. Mono mini-
plug connectors are provided for microphone inputs.
If required, microphones can be biased using the resistors
R
MIC1
and R
MIC2
.
This layout is set up to allow the use of the internal tone-
control circuitry or the external loop. The jumper next to each
C
LIN
capacitor controls which route the signal should take.
