Stem Mixing

Master Module for
V700 Stem Mixing Consoles

The M752 is the stem mixing master module for stereo consoles. It includes the stereo master chain, the auxiliary masters for the 3 mono aux sends and the 2 stereo cue sends, the PFL master, an additional stereo return input and a headphone amplifier.

Stereo Return Input Section
The stereo return input is completes the feature set of the master module. The return will usually be used for the output of a reverb device but can be used with any stereo line level signal as well. The input is balanced and can process levels of + 30 dBu. The input level is fixed and calibrated to a nominal value of + 6 dBu ~ + 4 dBV. The CUE pot drives the stereo send CUE1 pre fader. The pan control is a standard stereo to stereo balance control with 0 dB center attenuation. The Cut, PFL, Meter, and Solo section as well as the fader are not different from the M768 Stereo Input Module; however, the output of the pan control drives the main master only. A group select section is not included.

Mix Master
The mix bus amps are fed from the stereo master bus rails in the console frame. The bus amp outputs drive the mix insert section, that is balanced and buffered. The insert outputs are always available on the connector panel. The insert inputs are switched into the signal chain with the INS switch. The entire insert section can process levels of 30 dBu. The master fader is always post insert. It is implemented with a conductive plastic, stereo audio fader that drives special, wide range output buffer amplifiers. All outputs are electronically balanced and can handle + 30 dBu. Transformer balanced outputs are also possible; however, the optional transformers have to installed in a separate module due to the lack of space in the master module for appropriate output transformer that can process + 30 dBu at low frequencies. The stereo master module sets a V700 stem mixing console into MODE STEREO.

Aux and Cue Masters
The master amplifiers for the three mono aux sends and the two stereo cue sends are also included in the master module. Each send has a rotary master level control with a maximum gain of 6 dB and an AFL switch that routs the output signal post master fader to the PFL bus of the console. All output amplifiers are electronically balanced and can deliver levels of + 30 dBu.

PFL and Headphone Amp
The PFL master amplifier is part of the master module. The electronically balanced output is available on the connector panel. In addition, it switched to the internal headphone amplifier, if one or more PFL switches in the console are active. A LED next to the TRS jack indicate PFL mode. The headphone amplifier allows baisc control without additional, external equipment. If PFL is not active, the mix master output drives the headphone amp. The amplifier has a volume control pot and can be used with any headphones.

The Module
The M752 stereo master is a 6U, 1.5 slot wide V700 module with 120 mm depth that can be used with standard and custom build stem mixing frames
