DESCRIPTION
The MCM-32 from Heritage Audio takes mountable analog summing mixers to a whole new level. By combining vintage
quality sound with sophisticated routing options, they are the perfect partner for popular hybrid setups by integrating
analog gear with your DAW. The routing options are simply incredible as there are enough inputs and outputs for every
imaginable scenario. Now you can finally connect all of your equipment to one central piece for the ultimate control.
The smart summing topology employed in the MCM series of mixers allows for an impressive headroom and surprisingly
low noise figure for a 32 channel, vintage topology mixer. Special care has been taken on improving crosstalk and self-
noise figures from those of vintage designs in order to accommodate the new MCM mixers into the digital era.
Much has been written on the pros and cons between active (current) and passive (voltage) summing topologies. Some
may claim one is better than the other but the truth is active summing is less susceptible to noise and voltage, passive
summing has a nice, vintage sound associated with its gain makeup circuit.
The smart hybrid summing topology used in the MCM-32, where the channels are current-summed ( active ) into their
corresponding subgroups and the subgroups voltage summed ( passive ) into the master section, has proven to give
massive headroom and lower noise without making any compromises to its vintage characteristic sound.
The MCM-32 employs a unique configuration, offering 32 input channels arranged into 4 stereo subgroups of 8
channels. Each channel features center detent Pan and Fader concentric controls plus balanced insert and mute
switches.
The insert send points always have the signal present, so they can also be used as direct outputs for recording without
additional patch bays.
Each group has its own stereo fader and balanced insert point and all 4 stereo subgroups are passively summed into
the master bus. The gain is restored by means of a 73-style class A, transformer coupled, mic preamplifier, featuring a
total of 4 of our exclusive Carnhill transformers (an input and an output transformer for each channel of the stereo
master bus), capable of delivering a full +26 dBu output. This master section is also provided with its own balanced
insert point.
There is also a stereo MONITOR OUTPUT that mirrors the MIX OUTPUT for extra convenience.
All connections on the back are made by DB-25 connectors following the Tascam protocol, with the exception of the MIX
OUTPUT and the MONITOR OUTPUT connections, which are on dedicated gold plated XLRs.
