The Sections In Detail Pre and Post Insert Trims Pre Insert Trims Post Insert Trims Trim L Trim R Trim L Trim R Sophisticated rotary trim switches with 32 steps are used for precise gaining from -10dB to +10dB for each Pre Insert L/R as well as Post Insert L/R channel. These switches route the signal through one precision resistor at any position only, keeping thermal noise and tolerance at an unrivalled minimum.

The Sections In Detail Master Fader Master Fader Master Fader This fader features the same level control potentiometer as in the Monitor Level section for dynamic mastering purposes and fi ne tuning the overall level from +10 dB to -80 dB. The range can also be customized to operate from 0 dB to -80 dB.
Option: Master Bay The DMC can optionally be complemented with an insert box called MasterBay. The MasterBay MasterBay consists of a 4U insert box and a remote control panel. Up to eight, 2-channel processors can be connected to the insert box, which is operated by the MasterBay remote panel.

At low levels the noise floor accounts for the high percentage readings.
Power Supply For optimal audio quality and dramatically reduced inductive disturbance/ interference, the DMC’s power supply is divided into two parts. The external part houses a toroidal transformer, the linear power supply is built into the DMC housing. Input voltage: 110-120 V/60 Hz or 220-240 V/50 Hz Noise: ›...
