The new ART ProMPA II is the next generation in affordable high performance microphone preamp technology. Each microphone input circuit, with selectable 48v phantom power, features variable input impedance which can radically vary the overall performance of any high quality dynamic or ribbon microphone. The ProMPA 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.
The ProMPA II can operate at either a low or high plate voltage on the two integrated hand-selected 12AX7 tubes for wider variation of preamp tone and performance. Large back-lit analog VU output meters display output levels while multi-colored LED arrays show tube gain.
Housed in a standard 2u space rack-mountable steel chassis, with CNC routed black anodized aluminum face panel, the ProMPA II is designed to deliver years of reliable operation in the studio, production facility, or on the road for live sound reinforcement.
If you're looking to bring your recordings up to the level, there's nothing like introducing a quality preamplifier. And, with ART's Pro MPA-II, you'll have more than enough sonic range to dial in nearly any sound imaginable - no matter what kind of microphones you have in your mic locker right now, or the microphones you add to it in the future. That's because, on each channel you have selectable phantom power for your condensers. Plus, there's plenty of gain onboard for bringing your ribbon microphone signals up into usable levels. Beyond that, variable input impedance lets you draw out a rich range of tones from each of your microphones - use it to match the preamplifier to your microphones, or creatively mismatch tones for a unique sound. Plus, you can operate the ART Pro MPA-II at high or normal plate voltage, for an even wider range of sounds. There's also a per-channel low-cut filter to squelch issues with rumble.
Your preamplification needs will vary depending on what you want to do and what you're recording - but, luckily, ART equipped the Pro MPA-II with the flexibility to meet your changing needs. You can operate the preamplifier in dual-mono or stereo, to suit what you're recording. There's even selectable support for mid/side microphone setups.
Get an eye on what's going on using the ART Pro MPA-II's full assortment of metering. Onboard, two professional VU meters display input or output levels, while its multicolored LED arrays, with average or peak hold, show you tube gain.
