10 OUTPUT DISTRIBUTION AMPLIFIER

Transformer Balanced Earth Free Input

The D.A. Unit is a mains powered, general purpose distribution amplifier with a Transformer balanced input and a line bridging impedance of 10KR (line bridging option).

10 Earth Free Output Transformer Balanced Low Noise and Distortion Optional electronically balanced input also available.

Electronically balanced input option is available. Ten 600R outputs are available and are Transformer balanced and resistor isolated. Signals up to + 14dB are processed with low noise and low distortion. Outputs are short cct protected with thermal limiting and safe area protection are also incorporated.

The mains input is via a IEC mains connector. XLR connectors are used for signal inputs and outputs. Front panel mains indicator and fuse are provided.
