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
