AD256 is another addition to the Audio Developments Ltd range of portable mixers, having comprehensive facilities set out in an ergonomically friendly design and all contained within a robust and rugged aluminium case with a relatively small footprint.

The features and specification are based on the well established AD255 Mixer. Input channel limiter, continuously variable HPF and mute switch are the main additions. As with the other models within the range, professional components are used throughout - including Penny and Giles 100mm, long-stroke, conductive plastics faders.

Location sound professionals now require multi-track record facilities; the channel direct outputs provide the necessary features. By use of an additional switch these outputs can source other signals if the direct signal is not required, (Main Output and Auxiliaries). This without compromising the simplicity of operation and reliability as with its counterpart the AD255.
