Usage

The

Simple hookup for use as a general speaker

PINOUT
A - Ground (Both Audio and Power)
this is used for both the audio ground and a power ground
B - Unswitched 24v
This is used as a constant 24v source into the speaker, to use the speaker this is required as a minumum
C - Switched 24V in
This allows 24v to be supplied to PIN D when the power switch is turned on
D - Switched 24V out
24volts is applied here when PIN C is hooked up, when the power switch is turned on
K - RX Audio in (hook audio to this)
receive audio source is hooked here, this shoudl be isolated with a transformer if a 12volt radio is used
J - Remote PTT
S - routed to PIN A, Ground in normal cabling
this is usually the PTT line in VIC1 configurations, since this is routed the Ground, hooking this to a VIC1 using the wrong cable will cause the speaker to key the radio.
U - Transmit Audio

To make this function as a simple speaker, connect the following:
