LAN - Local Area Network connection for REMOTE CONTROL of PA (for future use)
PREAMP - RCA Phono, +12V / 100mA for an external RX preamplifier switching
CAUTION
If you are using an older transceiver or transmitters without time delay, we recommend to connect the PA in
such a way that the transmit/receive switch (foot switch for example) is connected with the KEY IN socket of
the amplifier. The KEY OUT socket is to be connected with the PTT socket in the transceiver.
The amplifier is equipped with two safety devices, which ensure that the output relay is not switched under
power mistakenly (hot switching).
KEY IN - RCA Phono – Input signal PTT (switching voltage / current 5V /2 mA)
KEY OUT - RCA Phono – Output signal PTT (maximum switching of 50V / 100mA)
Note: Option. Two SMA connectors for distribution of transmitter and receiver path with local RX preamplifier
connection possibility. Internal circuit ensure cold switching.
