ADA-8405-C User Manual (Iss. 02)Introduction • 1–1
Overview
Features
The ADA-8405-C is a remote gain analog audio distribution amplifier designed for broadcast use.
It can be used as either a mono 1x8, or two channel (stereo) 1x4 audio DA. When used with a Full
Rear Module, it provides eight copies of the single (mono) input signal or four copies each of the
two (stereo) inputs.
The 8320AR-043 Split Rear Module can support two ADA-8405-C 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 ADA-8405-C is also ideal to distribute Timecode (LTC) throughout a facility. In single
channel, 1x8 mode, the ADA-8405-C provides eight copies of the incoming single when used
with the Full Rear Modules or four copies of the incoming signal when used with the
8320AR-043 Split Rear Module.
The following features make the ADA-8405-C the best solution for distributing analog audio
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 DFR-8321 and OG3-FR series frames
using 8320AR-043 Split Rear Modules
•Balanced inputs/outputs
•5-year transferable warranty
