1. Introduction
- 1 -
˙ Each channel of the MP2D has 48V Phantom power available.
˙ A phase reverse switch is provided on each channel.
˙ A Rumble filter is provided on each channel for eliminating low frequency
noise.
˙ The MP2D offers a high quality transformer on each channel.
˙ Inserting stereo headphones into the jack on the front panel of the MP2D
enables the user to monitor the signals assigned to the Stereo bus.
˙ The MP2D has a stereo summing bus for combining the input signals
assigned to the bus using the L/R function switch on the front panel of the
MP2D.
˙ The output signal is available on the digital output in the AES/EBU format
and in the S/PDIF format (via the RCA connector) to the digital inputs.
