ART MPA Gold Microphone Preamplifier

No longer available at zZounds
Selectable tube plate voltage. Large VU meters. Tube Warmth LED meter.

A professional tube microphone preamplifier is defined by warmth, presence and clarity - core elements which make a performance truly come alive. Sister to the ART Digital MPA, the MPA Gold performs to incredibly high standards, and that it's tone, functionality and performance will satisfy even the most discerning user.

Like the Digital MPA, the MPA Gold features Variable Input Impedance. Variable Input Impedance is intended to optimize the MPA Gold for the widest range of microphones. Variation of the input impedance of a microphone preamplifier changes the load against which the microphone has to push. This variation dramatically alters the performance of a microphone, and creates numerous sonic possibilities for microphone performance. The variable impedance control of the MPA Gold is infinitely variable, as opposed to steps. This allows users much finer control over the tuning of the impedance.

Features:
Variable Input Impedance For Flexible Microphone Voicing (150 Ohms to 3000 Ohms)

Selectable Tube Plate Voltage

Large VU Meters with Range Switch

Tube Warmth LED Meter

Improved Discrete Class A Input Microphone Preamplifier

Lower Noise At Low Gains, Wider Frequency Response and Lower THD Than our Pro MPA

Front Accessible Instrument Input Jack With Very High Input Impedance

Automatically Switches To Instrument Input When You Plug In

The selectable Tube Plate Voltage function delivers a wide variety of tones. The tube circuit is differential, and provides read more the equivalent of a 300V power supply on the high voltage setting. Not to mention it has very low distortion and noise. Our normal setting maintains ART's classic tube sound (warm with smooth overload characteristics).

The MPA Gold's unique tube circuitry utilizes two 12AX7A vacuum tubes and renders unsurpassed sonic detail and clarity with the broadest range of microphones. The 12AX7A tube preamplification section provides gain while maintaining the incredible dynamic range of the previous stage and controlled overload characteristics.

Condenser microphones, ribbon microphones, dynamic microphones - new and vintage - all become more versatile and deliver their maximum performance when they interact with the MPA Gold's Variable Input Impedance. You'll discover that your microphones will sound better than ever.

In addition to the VU meters, the MPA Gold has Tube Warmth LED Metering which measures the left and right audio channel levels. The meters act like a normal histogram for the average signal level and the display holds the highest LED on alone for one second. While the average level function attack and release are measured in milliseconds, the peak function has a 20 microsecond attack time. Additionally, the analog meter range is switchable between -10dB and +4dBU. The MPA Gold's High Pass Filter is continuously variable from 15Hz to 150Hz. Many other preamps have a fixed switch. This makes our MPA Gold more flexible audio processor.

The MPA Gold is truly a modern, world-class tube microphone preamplifier, and its audio performance will surely exceed your expectations.

"A Great Sounding Pre Loaded With Pro Features!!"

Overall: 5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I will be satisfied for many years and would definitely replace it if something were to happen to it. It's a must have item if you're looking for a pro sound. I have a Great River ME-1NV which is also an incredible mic pre but there's a huge difference in the price. The GR is no better than this pre. They both have a sound of their own and all usable.

Sound
The sound of this pre is awesome. Of course you'll need to change the chinese tubes that come stock with the unit to take it to another level but fresh out of the box this pre will amaze you. I ordered a matched pair of Tung-Sol tubes for it.

Features
I can't believe how many features there are on this thing. You can really sculpt the sound of the source material in many ways. Variable input impedance for mics, selectable plate voltage, xlr inputs/outputs and 1/4" TRS outs and so much more. Incredible for the money.

Ease of Use
Very easy. Just plug and play. It does what a pre should do. deliver exceptional tone and sound. It looks great too.

Quality
It's made very well. The knobs are heavy duty and rock solid. Seems to me with proper care and handling this pre will provide many years of trouble free service. I do studio work only so it won't be going out on the road.

Value
The best "bang for the buck pre" out there IMHO.

I gave this category a 5 as I've never had to deal with support. I own a few ART products and never had any problems with anything.

The Wow Factor
Like I said it looks and feels great. Most importantly the sound is what a pre is all about though.
