Massenburg Preamp Plus EQ in One Case!

The Model 2032 Microphone Preamplifier / Parametric Equalizer is a single-channel, multi-input device for high-resolution studio and remote applications. Incorporating the renowned 8300 preamplifier and reference-standard 8200 equalizer, the Model 2032 inherits over thirty years of GML engineering excellence. This transparent Class A discrete design with internal supply delivers reliability, musicality, and precision.

The Preamp section of the 2032

The preamplifier section of the Model 2032 Microphone Preamplifier / Parametric Equalizer is based on the gain stage of the Model 8300 Transformerless Microphone Preamplifier, though there are some design changes and a few additions to expand its capabilities further than is realized in the highly specialized Model 8300 mic preamp.

A particularly wide range of gain settings (10dB through 75dB of gain) is available for both preamplifier inputs of the Model 2032. This feature accommodates a broad array of input signals, from extremely "hot" microphone inputs to extremely "low" MI inputs, which are often neglected by professional peripheral audio processing devices. Indeed, the minimal 20dB of gain found in most microphone preamplifiers can be excessive in certain circumstances, and decreases the possibility of optimized gain staging. By the same token, real-world MI signals often require more than the typical 10dB of gain commonly accorded them.

A combination of the rotary Gain switch and Fine potentiometer is used to control the gain setting of the preamplifier section, with the overall gain of the preamplifier calculated by adding the two control values. The Gain switch allocates between 15dB and 70dB of gain in precise 5dB steps, using a combination of discrete resistors for the ultimate in accuracy, stability, durability, and sonic integrity. Providing +/-5dB of continuously variable gain, the Fine control adds elasticity to gain setting.

Multiple inputs for today's desktop and professional studios!

The inclusion of multiple inputs certainly adds to the allure of the Model 2032, where the MI input circuitry represents a welcome addition to the standard microphone input. The Input XLR can even accommodate low-level "line" sources needing 10dB of gain or more, assuming the external device's output can drive the 1k! load impedance. Thus, the Model 2032 preamplifier can capably handle a wide array of input sources.

High-Pass Filter section

Immediately following the preamplifier section of the Model 2032 is an extremely useful and transparent highpass filter (HPF), which has three optional settings: 40Hz roll-off, flat response, or 100Hz roll-off. Designed for maximum clarity and musicality, this active second order Butterworth highpass filter is implemented with premium-grade SMD film capacitors, precision resistors, and a pristine GML 9202 discrete opamp. Passband response is maximally flat for both the 40Hz and 100Hz selections, while the Model 2032's ruler-flat frequency response is preserved in the "flat" setting. A secondorder highpass filter, this circuit creates a -12dB per octave roll-off below the corner frequency, an appropriately flexible and powerful function since many engineers use the low-frequency band of a fully parametric equalizer - a Model 8200, for instance - in shelf mode as a highpass filter of sorts.

Parametric EQ section of the 2032

The EQ section of the Model 2032 Microphone Preamplifier / Parametric Equalizer offers precision and adaptability when sculpting the response of any source. Its operational characteristics, duplicated from the Model 8200 Parametric Equalizer, have been honed through many years of use in the most critical recording and mixing situations and have proven both reliable and remarkably accommodating.

The basis of the parametric design topology, in general, specifies control over not only gain or attenuation, but also over both frequency and "Q" factor in multiple user-defined bands. In the case of parametric equalization, "Q" is defined as the center frequency of the alteration (whether gain or attenuation) divided by the bandwidth of that alteration. It follows, then, that low values of "Q" affect a wide range of frequencies around the cut or boost, while high values of "Q" specify a narrow slope around the center frequency. Another important aspect of true parametric equalization, as embodied in the Model 2032 equalizer section, is the existence of overlapping frequency bands, which provide great precision and flexibility.

Built-in power supply for convenience

The most notable and noticeable addition to the aforementioned GML legacy products embodied in the Model 2032 is the inclusion of an internal power supply--a first for GML. While the absolute lowest noise performance can best be achieved with an external power supply, this completely original design minimizes the compromises in order to yield the savings in space and cost that can derive from an internal supply topology.

The finest components!

Great care has also been taken--as in all aspects of the GML Model 2032--to select the highest quality components, from the potentiometers on the front panel to the smallestpassive elements. This attention to detail partially elucidates the quality found in the Microphone Preamplifier / Parametric Equalizer. These component choices, coupled with superior design techniques and a proclivity towards innovation, combine to make the Model 2032 a most powerful, flexible, and transparent single channel processor.

Incredible dynamic range

Another feature that distinguishes the Model 2032 is its inherent dynamic range. Naturally, this means that the preamplifier and filter sections maintain low-noise, highheadroom, transparent operation under all signal conditions, at any control setting. In the equalizer section, this extended dynamic range allows for the addition of 15dB of gain in multiple frequency bands simultaneously without even a hint of distortion or loss of detail and authority. This amazing accuracy is due in large part to the GML propensity to design all audio circuits from discrete components. Discrete designs, when executed properly, help to preserve not only sonic integrity and musicality, but also to maintain the widest dynamic range through the entire signal path, thus eliminating many sonic compromises and limitations. Not only do these discrete topologies--and the GML 9202 discrete opamp in particular--sound better than their integrated counterparts, they also offer the ability to design for higher signal levels internally, while also optimizing dynamic range by providing a low noise floor.

If you can afford it buy it!

The mic pre is colorless and very 3D! Just amazing like you are in the room. What you would hear if you were in the iso room... no joke. Plus you get an incredible EQ with perfectly chosen overlapping frequencies designed by the guy who invented parametric EQ!!!! You might wonder if you have it engaged for lighter EQ adjustments because you don't hear the frequency changes until you bypass the EQ, only to realize it was engaged but only adjusting the frequencies without adding "color" while increasing overall fidelity. Even with heavier handling of the EQ this remains true. Say the low spectrum is boosted pretty well, It just sounds bigger in the spatial field, no muddiness here...Also, no noise whatever the setting unless it is in the source itself. By capturing the best source, everything gets easier. Less need for further processing. If GML made a console with these strips and incorporated their compressor / Limiters into buss groups and Master it would be a real game changer and favored competitor for any analogue board from the industry leaders and probably start a new musical revolution! The better an engineer captures the true unadulterated sound source, the more options available to the engineer in manipulating the source material to taste and genre. Much easier to add than take away ...worth every cent to me...seriously.

Excellent Audio

Besides being clean (yet superbly full) the 2032 has become my #1 direct input for electric bass and guitar. It's the fullest clearest DI I've ever used and prefer over my Avalon (which I sold) and the DI on my Avid OMNI. On top of that the EQ bands overlap so well that you can carve anything you want. It's an amazingly natural EQ which just makes whatever you put through it sound like it was that great at the source. For me, just the DI is worth it. It's that good.

Simply Outstanding!

First, let me say that I have used and tested a variety of mic-pre's. This one is a keeper! Everything I plug into it seems to come alive. Almost a 3D type sound. Bigger, warmer, etc. The EQ is one of the most musical I've worked with. I'm convinced that nothing sounds bad going thru this baby.This was money well spent. I'll have this in my studio for along time.

This Pre Delivers What It Promises

I used both the preamp and EQ (which you can insert separately) extensively on vocals with both my U87 and Sm7 microphones during the four years I had my project studio. It was extremely difficult to part with this piece of gear: it produces a beautiful clarity, and you really have to boost the 3k region mercilessly to produce any harshness. My 4.5 rating (instead of a '5") is merely a hook for this caveat: the heavens don't open when you process vocals through a GML 2032; your room does, as well as your performance. This is a very revealing preamp which provides incredible depth and detail, which is why it is critical to take care in preparing both your recording space and, of course, your vocals. Look up "quality" in the dictionary, and you may see a picture of GML gear next to the word...

Sweetwater Advice

Ted Hunter

The 2032 has the cleanest preamp I've ever encountered, and the equalizer is so transparent I had to keep bypassing it to make sure it was engaged. It works the way an equalizer is supposed to work.

David Stewart

One of the sweetest and most natural sounding EQ's I've ever used.
