SUMMING MIXER DESCRIPTION
The MCM-8 features a passive voltage summing topology, similar to that found in the
vintage Rupert Neve era discrete consoles.
Passive voltage mixing requires its gain loss to be restored back to line level. Again,
following the vintage topology, a stereo transformer coupled class A output amplifier is
employed for this task. This amplifier is the same one used in the 1073 module.
The stereo Master Fader is placed PRE output stage, so driving it to saturation is
possible. (and the opposite too!).
Provision is made on each channel for attenuation and stereo placement (fader and
pan) before sending to the mix bus, with the exception of the AUX inputs.
Maximum output level is greater than +26dBu (headroom for days… ).
USING THE MIXER WITH EMPTY SLOTS
The MCM-8 mixing section is designed to be used with modules fitted. However it is
possible to use it with empty slots by patching input signals into the MCM-8 slot´s outputs.
This trick will effectively bypass the slot with full signal integrity and no degradation.
To do this using the single XLRs, female to female adaptors may be used.
