ASD-880 Stereo Audio Distribution
Amplifier Module
Overview
The ASD-880 stereo audio distribution amplifier is designed to meet the most
demanding requirements of broadcast facilities, television post-production, and
recording studios. This excellent amplifier provides one high performance
channel with eight balanced outputs. Outputs can be customized to low (66
Ω
),
as per AES recommendation 1708 (I-3), or 600
Ω
impedance. Future impedance
modifications are also possible, should requirements change. Excellent output
isolation and interchannel crosstalk is assured by the individual drivers for each
output.
The input is overvoltage protected up to 120 volts AC or DC. The
transformerless, balanced input is normally bridging, but can be terminated by
installing a suitable resistor. Unbalanced input is converted to balanced output.
The ASD-880 exceptional performance features include 100 dB S/N ratio, flat
frequency response, carefully controlled roll-off and very low distortion, thus
ensuring a virtually transparent transmission path. The extended shaft option
allows for front panel gain control in the FR-881-S and FR-882-S Mounting
Frames.
