MONO AUDIO DISTRIBUTION AMPLIFIER
AMD-880
• Very low noise (100 dB S/N)
• Eight outputs per module
• Available in 66W, or 600W output impedance
• Input over-voltage protection
• Virtually transparent
• +24 dBm maximum output level
• Gain range -6 to +33 dB
The AMD-880 mono 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 (66W), as per AES recommendation 1708 (I-3), or
600W impedance. Future impedance modifications are also possible,
should requirements change. Excellent output isolation and interchannel
crosstalk is assured 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

STEREO AUDIO DISTRIBUTION AMPLIFIER
ASD-880
• 1 in 4 out stereo
• Compatible with all Leitch audio DA frames
• Available in 66W, or 600W output impedance
• Very low noise (100 dB S/N)
• Excellent interchannel crosstalk (>95 dB)
• Gain range of -6 to +33 dB
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
two high performance channels with four balanced outputs per channel.
Outputs can be customized to low (66W), as per AES recommendation
1708 (I-3), or 600W impedance. Future impedance modifications are also
possible, should requirements change. Excellent output isolation and
interchannel crosstalk is assured by the use of individual drivers for each
output.
The input is over-voltage protected up to 120 Volts AC or DC. The
