The main differences between this version and its predecessor are:
Extra 500 series button per channel, allowing to bypass the 500 series module when mixing if desired. It also allows for quick comparisons between processed/unprocessed signals, as well as making using the mixer with empty slots much easier. Simply unpressing the 500 button allows for this type of operation. Significant lower noise. A highly innovative, new quasi-balanced voltage summing topology sets the noise floor of the new MCM-8 II touching the theoretical minimum. No more hiss in your mixes!
Standing for Music Compact Mixer 8, the MCM-8 II is an 8 slot 500 Series enclosure with 10 channel mixing capabilities and is the Top of the Line of the new Heritage Audio “ON SLOT Technology” (OTS) 500 Series enclosures.
“ON SLOT TECHNOLOGY”
Takes advantage of the lastest of generation power electronics to handle power supply on a “per slot” basis. Each slot has its own power linear supply regulation stages; therefore modules are isolated from the rest. They just share the metal enclosure.
With literally hundreds of brands making 500 series modules, we at Heritage Audio think this is the professional way of handling this reliably, eliminating issues often associated with sharing power between different modules of different brands and requirements.
Each slot features test LEDs for checking correct power operation (red for +16 V, green for -16 V), located aside of the slot connector.
Thanks to the use of OST, the power capability of the MCM-8 II is 400 mA per slot maximum, with an overall of 1,4 A (1,6 A non continuous) per rail, whichever is reached first.
Phantom power available is 140 mA.
The RAF Blue Gray enclosure is made out of heavy gauge steel with an aluminum front panel to ensure an attractive look for your studio.
There are Pan and Fader controls per slot on dual concentric potentiometers. Pan pots are center detent for precise center positioning. Features include an ON switch to assign each channel to the Mix Bus.
The Mix Bus follows a passive, voltage summing topology, similar to that found in the 80 Series consoles of the 70s. The gain loss is restored by the same Class A, 2n3055 driven, transformer based output stage used in the Heritage Audio DMA 73.
An additional Stereo Input is provided on the back of the unit, allowing several MCM-8 II units to be daisy chained, or signals not needing further 500 series processing to be mixed together.
The central section has analog VU meters and a Stereo Master fader.
Connections are made by both gold plated XLRs and DB25 Input and Outputs, following the standard Tascam protocol.
