Product Description

The ART Digital MPA-II delivers all of the same great features of the ProMPA with the added versatility of digital output. Like the ProMPA-II, each input circuit has 48v phantom power and features variable input impedance which can radically vary the overall performance of any high quality dynamic or ribbon microphone. The Digital MPA-II can be configured for dual mono or stereo operation with selectable mid/side mic support, summing the adjacent channel, to decode left/right signals.

Features

- Variable input impedance for flexible microphone voicing (150 Ohms to 2400 Ohms)
- Selectable plate voltage
- Large VU meters
- Backlit function switches
- Discrete Class-A input microphone preamplifier
- Low noise at lower gain settings
- Extremely low total harmonic distortion (THD)
- Wide frequency response
- Additional front mounted instrument input jack
- Operates at +4dbm/-10dbv output
- Selectable stereo/dual operation of output controls
- Automatic instrument input selection
- 24-204KHz external sample rate
- 44.1K, 48K, 88.2K, 96K, 176.4K, 192K internal sample rates
- 24/16 bit switchable dithering
- Wide dynamic range A/D
- Rotary Encoder for quick selection of sample rate
- Separate analog and digital output level controls
- Digital Level LED meters display both Average and Peak level
- ADAT optical I/O
- Sync to incoming ADAT data rate
- Switch selectable optical output (S/PDIF or ADAT)
- AES/EBU and S/PDIF outputs
- Two wordclock jacks allowing loop through

The input section of the Digital MPA-II operates at either a low or high plate voltage applied to the two integrated hand-selected 12AX7 tubes for wider variation of preamp tone and performance. Large back-lit analog VU output meters display input or output levels while multi-colored LED arrays, with average or peak hold, show tube gain and digital output levels.

In addition to XLR and 1/4-inch analog outputs, the Digital MPA-II features a high quality A to D converter which offers digital connectivity on S/PDIF, ADAT, or AES/EBU outputs. A rotary control on the front panel allows selection of format and sample rates from 44.1 to 192 KHz and 16 bit dithering. There is also a push button for, and two wordclock jacks, allowing loop-through.

The Digital MPA-II comes in a standard 2u space rack-mountable steel chassis, with CNC routed black anodized aluminum face panel. zZounds is an authorized dealer of ART products.

Customer Reviews
4.5 out of 5 (13 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Buy this. If short on cash, get the non-digital version"
Sound: Over the past year, I have bought pretty much one of every make of cheap tube preamp out there, including this one. How does it rate? The best of the bunch. Of course it is the most expensive... But you do get two channels. I like this unit, but would urge readers to change the tubes. The Chinese tubes in it are not that great and really do not let the unit sing. I use Mullards and and am very happy, especially at high plate voltage. The unit has a fairly shallow noise floor and so is not totally pro gear, but for the price, it is better than anything I have found. Feature: Nice features, including the dual plate voltage. Have not fully tested out the digital features yet, though. Ease of Use: Easy to use and a good manual. Quality: It is a well made medium quality unit. I think the weak link in all Art products seems to be the power supply and I would encourage users to run it through a power conditioner/filter system. Value: Solid value --this digital unit and the less expensive analogue sibling. If you have the cash, buy it. Manufacturer Support: no experience The Wow Factor: Looks fine. I mean, it's a rack mount unit --what do you want? Overall: If I lost mine, I would replace it. Though, maybe not the digital version, depending on what converter I had at the time. But the preamp is best value for the money out there, if you are into the tube sound --which I am.

zZounds has verified that this customer bought this product from us. "The ART mic preamp is a real bargain and a must for any recording studio."
Sound: I am currently working with the ART mic pre amp and it is an awsome piece of equipment. It gave my condenser mics more room to breathe and it offers much more. I am using it in my homme studio and will surely look into other ART products. It fit my situation. Feature: No accessories bring used. Ease of Use: The ART is user friendly. Not complicated all you need is patience and apply your settings. Adjusting your mixer and other equipment is vital, but the end result will is very positive. Quality: The ART mic pre amp seems to be very well made. In my case it is rackmounted in my home studio, so it will surely stay in good condition. It looks good and the meters and led lights make it bright and easy to see from a distance. Value: Absolutely. Good deal. Manufacturer Support: Have not dealt with the company. The Wow Factor: It's an eye opener. It looks like it definetly belongs in a recording studio. Overall: I have been using it for a couple of weeks, and I have gotten very positive results.

1. zZounds offers the industry‘s most musician-friendly payment plans

zZounds offers a variety of Play as You Pay installment plans that allow you to get the gear you want today.

Unlike those house credit cards that can leave you vulnerable to exorbitant interest charges once the promotional period ends, we never have and never will charge interest when you take advantage of one of the zZounds Play as You Pay plans.
