•Clean, noise-free transition during gain setting changes
•Transparent performance even in the most critical broadcast applications
•8 independent channels
•Control of the amplifier gain of the left and right channels— together or separately—via the front panel buttons, or remotely via RS-232 or RS-485
•Daisy-chaining of up to 15 machines in a single system using RS-485 or RS-232, allowing control of up to 120 stereo audio channels!
•Storing and recalling up to 15 configuration setups via the non- volatile memory, using the front panel buttons, or remotely via RS-232 or RS-485
