Quote from the Acom 1000 manual...

" e) The KEY-OUT socket on the rear panel provides an extra control signal
from the amplifier to the transceiver. It could be used to improve the
transmit/receive switching safety.

If your transceiver has a suitable input that disables transmission, we
recommend that you connect it with a cable terminated in a Phono (RCA)
connector to the KEY-OUT socket of the amplifier. Transceiver producers give
different names to this input and they are for instance TX-INHIBIT, MUTE,
LINEAR, etc. Check your transceiver's manual or consult your dealer.

If your transceiver does not have such input, don't worry - the amplifier
will function normally as well, and then the KEY-OUT may remain unused. "

Does this constitute a recommendation?

Take your pick.
