75-Ohm (Unbalanced) AES Distribution Amplifier with Remote Gain Control
Product by: Cobalt Digital
The 9913DA-AES75-RG 75-Ohm (Unbalanced) AES Distribution Amplifier with Remote Gain Control is a broadcast-quality AES distribution amplifier that provides up to eight copies of the input AES-3id signal. A transformer-coupled input helps prevent ground loop and other grounding-related problems.
The 9913DA-AES75-RG supports audio sampling frequencies from 32kHz to 96kHz. Cable equalization and reclocking techniques enable the 9913DA-AES75-RG to recover the incoming digital audio signal reliably. The 9913DA-AES75-RG also includes built-in loudness measurement, with ITU1770 LKFS loudness measurement displayed in DashBoard.
A built-in DSP allows mono-mix and L/R-only outputs (these functions can be locked out for Dolby® signal processing). The DSP attenuation function allows overall gain (stereo ganged) trim (offset) via DashBoard™ remote control.
The space-saving design and very low power consumption of the 9913DA-AES75-RG provides for high density, allowing two cards to be collocated in adjacent slots and served by a single, standard-width “split” rear module.
Features
Full remote control of operating mode and gain control
Multiple DSP modes – stereo/pass-thru, mono mix, L/R only outputs
Transformer-coupled input prevents ground loop issues and other ground-related problems
Convenient DSP gain trim via DIP or remote control (gain disable for Dolby/non-PCM usage)
DashBoard LKFS loudness display (10-second averaging)
Selectable card switch control or DashBoard™ remote control (usable with DashBoard™ and Cobalt OGCP-9000 remote control panels)
Five year warranty
