Shure RKC190 User Guide

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 side (3-pin female connector) of the RKC190.

2.Connect the TO AMS MIXER side (3-pin male connector) 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 up until the channel input LED on the AMS mixer turns off. Then slowly turn the threshold control back down to the point at which the LED illuminates again.

CAUTION

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.)
