Maag Audio
PREQ2 Dual Microphone Preamp with EQ
Additional Photos:
The PREQ2 will handle either line or microphone signal levels with two matched channels both with separate rear panel line level input and microphone XLR connectors and switchable +48-volt phantom powering. The rear panel also has XLR output connectors for each channel and a on/off/fuse mains switch.
All switches on the PREQ2 have colourful LEDs to confirm their operation and all controls have detents with the exception of the continuously variable microphone gain.
Microphone Input
The Maag Audio PREQ2 microphone preamp has up to 71db of gain split between a discrete class-a transistor preamp along with a large, nickel-core Maag audio-built input transformer (one for each channel). This circuit offers a clean, detailed sound with +27dbu of headroom and an ein noise level of -128db. There are two optimised gain ranges selectable on the front panel. The default gain range is +20db to +42db and a +42 to +71db gain range in high gain mode using the front panels 25db gain switch. Maximum input level is +8db.
The microphone input section has front panel switches, LED indicators and buttons for: +48-volt phantom powering, -20db attenuation pad, plus signal present, +26dbu peak leds, and phase or polarity flip. Microphone gain is continuously adjustable using a single, large mic gain control knob.
Line Input
The front panel line switch toggles the rear panel XLR line input connectors in place of the microphone preamps output (after the input transformer and microphone preamp). It is possible to keep both a microphone and a line level source always connected to the PREQ2 and toggle both channels separately. You could have one channel working as a microphone preamp channel and the other as a line level amplifier for recording a direct musical instrument (bass or guitar) at the same time.
Both mic input sections have 1/4-inch ts jacks for high impedance (1 mega-ohm) instrument input with a companion 1/4-inch output thru jack that simultaneously provides an isolated, buffered outputa "copy" of the instrument input signal at unity gain. In addition to providing an unbalanced signal for running long leads out to instrument amplifiers in the studio and/or stomp pedals, for live re-amplifying the thru jacks output signal is also active when using the XLR microphone input.
When using the instrument input ts jack, the Maag audio PREQ2 uses an automatic detection circuit to switch (using a relay) and route the unbalanced 1/4-inch input signal to the mic input transformer. The impedance is lowered for a better match to the transformer. This detection circuit makes it is impossible for the 48-volt phantom power to ever reach the 1/4-inch or XLR line input even if already turned on.
Equalisation Sections
The Maag audio PREQ2 has three equaliser/filters sections; the layout and control compliment are identical for both channels. The equaliser design is specifically designed for both recording and/or subtle touch up tonality changes and euphonic enhancements.
On the left side of the channel is the first control for the 2nd order, 12db/octave high pass filter. It is fully variable using a 21-detent control to sweep from 20hz to 200hz. It has its own hardwired, in/out bypass switch.
Next is the low frequency bell-shaped equaliser section with a boost (only) control at 6db/octave. Frequencies are switched using a six position rotary switch and are: 10hz (sub) shelf, and bell-shaped curves for 40hz, 65hz, 100hz, 125hz, and 165hz. Up to 9db of boost is available.
Air Band®
The third band of the equaliser is the Maag audio air band shelving section with 2.5, 5, 10, 15, 20, and 40-khz frequency choices with its own control and up to 9db of maximum boost. Both the air band and low frequency equalisers share a single bypass push-button.

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.
