RKC190-AMS INTERFACE

The RKC190 AMS interface connects a line-level
output, such as that from a wireless microphone re­ceiver, to a microphone input of a Shure AMS mixer.
It features an adjustable threshold gate.

Installation

1. Connect line-level output (–36 to 0 dBV, 200
ohms to 5 kilohms, balanced or unbalanced*) to
the LINE IN

RKC190.

2. Connect the TO AMS MIXER side (3-pin male con-

nector) of the RKC190 to a microphone input of the
AMS Mixer.

Adjusting the Gate Threshold

1. Send a test signal or program audio at the mini­mum desired level through the RKC190 to the

AMS mixer.

2. Using a screwdriver, turn the threshold control

Do not force the Threshold control beyond the
stops at each end of its travel.

3. Use the gain on the AMS mixer to adjust the au­dio level for that channel.

*The signal lead of an unbalanced output should be
connected to Pin 3 of the 3–pin connector. Polarity
will be reversed at the output of the AMS Mixer (po­larity is not reversed for a balanced source.)
