MCM32 Rackmount 32-Channel Summing Mixer
Additional Photos:
The MCM-32 employs a unique configuration, offering 32 input channels arranged into 4 subgroups of 8. 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 be alternatively 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 1073 style class A, transformer coupled, mic preamplifier, featuring a total of 4 transformers (1 input one output in each channel). The master section is also provided with its own balanced insert point.
All connections on the back are made by DSUB 25 connectors following the Tascam protocol, with the exception of the master bus connections, which are by dedicated XLRs.
Vintage Sound and Low Noise
The smart summing topology employed in the MCM series of mixers allows for an impressive headroom and surprising low noise figure for a 20 channel, vintage topology mixer. Special care has been taken on improving crosstalk and self-noise figures from those on the vintage designs in order to accommodate the new MCM mixers into the digital era.
The transformer based class A output stage is able to deliver a full +26dBu output.
Controls Per Channel
ON: When pressed, the related input is added to the subgroup bus. When depressed, it's muted.
INS: Turns the insert on. The insert send always have the signal present, whilst pressing the INS switch activates the insert return input.
FADER: Attenuates the signal sent to the subgroup bus from unity to minus infinity. Fader all clockwise means unity gain, whilst 12 o'clock means an approximate 20 dB of attenuation. (Or -20dB of gain).
PAN: Places the signal within the stereo spectrum, left, center, right or any intermediate setting. The panoramic law follows a standard in which if a 0dB signal is hard panned, it is -3dB when center panned.
AUX SEND LEVEL / PAN: The aux sends are implemented on the blue concentric knobs below each channel. If AUX 1 and 2 are selected, inner knob is aux1 send and outer is aux 2 send, whilst having Aux 3 selected inner blue knob turns into stereo level and outer becomes pan.
PRE: Takes the aux signal from the channel PRE or POST Fader.
3ST: Chooses between AUX 1 and 2 or 3ST.
Master Controls
VU Meters: Measuring the average level at the master outputs. They are calibrated at 0VU = +8dBu.
Master Fader: Attenuates the Mix's output from unity to minus infinity. The control has a stepped feel for easy recall of settings. Fader all clockwise means unity gain, whilst 12 o'clock means an approximate 20dB of attenuation.
ON: When pressed, the output of the Master is sent to the Output connectors. When depressed, it is muted.
INS: Turns the insert on. The insert send always have the signal present, whilst pressing the INS switch activates the insert return input

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
- USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
