Introduction
The 8912RDA module is a low cost, high density analog audio distribution
amplifier (DA) available in single- and dual-channel versions. It is
designed for use in the 8900 Audio Frame. The single-channel module has
one balanced and one unbalanced (BNC) input and produces eight 110
Ω
balanced outputs. The dual-channel version has two balanced inputs and
two unbalanced inputs and produces four 110
Ω
balanced outputs per
channel. Balanced or unbalanced inputs are selectable by channel and can
also be jumpered to have 75
Ω
, 110
Ω
, or high input impedance. The AES
data is reclocked by means of a phase-locked-loop (PLL).
The 8912RDA features:
• AES3 or AES3id inputs with selectable 110
Ω
, 75
Ω
, or Hi impedance,
• Eight single (RDA) or four dual (RDA-D) AES3 110
Ω
balanced outputs,
• Outputs re-clocked at any data rate from 32 kHz to 96 kHz, and
• Remote and local reporting of input lock and input error.
