Your amplifier will not work if KEY-IN is not connected properly.
Transceiver producers give different names to this output and they are for instance TX-
GND, SEND, T/R-LINE, etc. Some transceivers require that "ground on transmit" is
implemented via a software command, or by changing the setting of a switch on the
rear panel, or interior of the transceiver. Check your transceiver's 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.
f) Preparation of wall outlet for the amplifier.
If your amplifier is only fitted with one mains fuse, it is suitable for 0-220...240 VAC
electricity supplies ONLY (these supplies are standard in the European Community).
Your dealer will check that your amplifier is correctly fused before it is shipped to you.
Customers should check with a qualified electrician if the amplifier is to be used outside
the country in which it was purchased.
Due to the different standards in different countries, the mains plug is supplied and mounted by the
dealer. He connects to the mains cord end a standard mains supply plug which meets the Safety Class I unit
standard in your country. The ground lead of the amplifier's power cord is colored yellow with two green
stripes and the blue and brown leads are active. When the amplifier is to be used with only one mains fuse,
it is connected in series with the brown lead, which must be the active. If you have any doubts about the
correct way of connecting the wires, consult your dealer.
Внимание!
Danger!
Before connecting the amplifier to your mains supply, be sure that the supply is
correctly wired, and is adequate for the current drawn by the amplifier (up to 10A).
Make certain that the grounding lead is connected properly in the wall outlet for the
amplifier.
