About Audio Developments AD255
The Audio Developments AD255 6 Inputs/2 Outputs Film Location Mixer is the latest 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 aluminum case with a relatively small footprint. The features and specification are based on the well established AD245 Pico Mixer. Two auxiliary sends and channel direct outputs are the main additional features. 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; without compromising the simplicity of operation and reliability of its counterpart the AD245. The headphone monitor may be switched between main output, auxiliary outputs and return. All have PFL override. Monitor selectors allow left, right, left + right, auxiliary 1, auxiliary 2 and auxiliary 1 + 2 to be routed to the headphone socket. An M-S matrix amplifier may be inserted in order to decode main or auxiliary outputs in the M-S domain.
