9242 Product Manual (V1.1) Introduction • 1-1

Overview

The 9242 is a Analog Audio Distribution Amplifier with Remote Gain Control designed for broadcast use. It can be used as either a mono 1x8, or two channel (stereo) 1x4 audio DA. When used with the standard RM20-9142-B Standard-Width Rear Module, it provides eight copies of the single (mono) input signal or four copies each of the two (stereo) inputs.

The RM20-9142-C/S Split Re a r Module can support two 9242 cards, each operating as a 1x4 audio DA. This can be used to separate left and right stereo pair signals to be amplified in separate paths for critical signals.

The 9242 is also ideal to distribute Timecod e (LTC) throughout a facility. In single channel, 1x8 mode, the 9242 provides eight copies of the incoming single when used with the RM20-9142-B StandardWidth Rear Module or four copies of the incoming signal when used with the RM20-9142-C/S Split Rear Module.

Features

The following features make the 9242 the best solution for distributing analog aud io signals:

• 1x8 Mono or 1x4 Stereo Analog Audio Distribution

• +/- 15dB Remote Gain control

• Summing capability

• Low Distortion

• 1x8 or High Density 1x4 Timecode (LTC) Distribution

• Higher density with up to 20 cards per frame in the 8321 series frames using RM20-

9142-C/S Split Rear Modules

• Balanced I/O

• 5-year transferable warranty
