Model Description:
AMD-880 mono audio distribution amplifier(eight balanced 600 ohms outputs)

Model Details

The AMD-880 mono audio distribution amplifier (DA) 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 66 ohms or 600 ohms impedance. Excellent output isolation and inter-channel crosstalk are ensured by the use of individual drivers for each output.

The input is over-voltage 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 AMD-880's 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.
