Audio Developments 256 8 Channel Mixer - USED


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..


  • Low noise microphone amplifier with powering for 48V Phantom and 12V Tonader (TA) powering.
  • 6 to 12 input frame, mic or line selection.
  • A simple, but effective, three band equaliser, proved and approved under field conditions, in use throughout the AD140 Series of mixers.
  • Inputs are balanced and protected against radio-frequency interference. A continuously variable high-pass-filter protects against low-frequency saturation.
  • The main stereo output is transformer balanced and has separate left and right fader control.
  • Two auxiliary outputs are transformer balanced and have separate master rotary controls. Auxiliary 1 & 2 are routed from each input using a 3 position switch (off, pre & post fader). Auxiliary 2 has a rotary level control on each input.
  • A mono output of the left and right signals is also transformer balanced.
  • Direct outputs from each input channel are unbalanced using a very low output impedance drive amplifier enabling high drive capability and minimising line interference.
