Studio Microphone Preamps

Notes: You need to add 3 mics to a mixer, which only has one available channel. Just insert a ProMIX between the mics and the mixer. Each mic channel on the ProMIX has both phantom power and low frequency cut selectable via DIP switches plus a level control. The balanced XLR line output can be connected to a mic input on the mixer and headphones or a powered monitor can be connected to the phone/aux output.

And if AC power is not available, the ProMIX runs on batteries as well.

Notes: Whether you're working with a computer, hard disk or digital multi-track recorder, the Tube MP's TEC award nominated design will allow you to obtain professional results at an affordable price.

The ART preamps offer warm tone, useful features and are innovatively designed. ART's line of Tube MP products add presence, clarity and fullness to any signal and is exceptionally low noise. The ART Tube MP Studio V3 features V3 Technology (Variable Valve Voicing), which provides optimized reference points to begin the recording process. The V3 delivers a wide variety of settings designed for various microphones and DI inputs, including guitars, basses, keyboards, synths, electronic drums and much more. Don't settle for a copy cat look alike.

Go with the real thing, the Tube MP by ART.

Notes: The Tube MP/C (PreAmplifier/Compressor) is a multi-purpose tool for audio engineering and recording. 2 independent circuits featuring a tube based analog preamplifier and a VCA-less compressor with optical gain reduction control are housed in one, convenient desk-top chassis. Used as a mic/line preamp or as a DI (direct) box, the Tube MP/C is designed to work seamlessly with any recording, sound-reinforcement, or electronic instrument setup. ART's Tube MP/C circuitry is a hybrid design utilizing the latest, most advanced, solid-state and tube technology.

The preamplifier's active balanced solid-state input provides extremely low noise and excellent common mode rejection. The 14" high impedance input prevents loading of any connected device making the Tube MP/C perfect for DI or line level applications. The preamplifier's second stage 12AX7a tube runs on a regulated DC voltage providing an additional 20 dB of gain.

The compression circuit features a VCA-less design and utilises optical electronics (Vactrol) coupled with a 12AX7a vacuum tube gain stage for superior musical performance

Notes: The USB Dual Pre is a full-featured high quality dual portable preamplifier and computer interface packed into a compact rugged case.

It is designed to work over a wide variety of applications from remote field recording to desktop/studio tracking. Each of the 2 low noise input channels has up to 48dB of clean gain with signal present and clip LED indicators. Inputs can be either XLR balanced or 1/4" TRS. Each of the 1/4" TRS outputs is buffered low impedance balanced.

The USB Dual Pre is powered via the USB bus. An internal 9V battery, or optional external 12V power supply (or any combination of USB, battery & power supply) can be used depending on application. When running powered by battery alone, you should expect in excess of 50 hours of operation with phantom power off. Battery life will drop to approximately 20 hours (depending on microphone) when phantom powering is engaged (still enough time to get through an average session).

The built in low noise +48V phantom power supply allows you to power up to 2 microphones as well as the preamplifier when running from any power sources including the USB bus.

For monitoring, a 1/8" TRS mini headphone jack with level and monitor mix controls on the rear allow for latency free local monitoring of the inputs while recording as well as playback monitoring of the USB bus. The monitor mix is also routed to the 1/4" TRS balanced outputs. This lets you use the 1/4" outputs as either preamplifier outputs or as the monitor feed to your powered monitors.

The USB interface is fully compliant with the USB 1.1 specification and uses USB adaptive mode for playback and USB asynchronous mode for record. It will work with the USB audio device drivers built into Windows 98SE/ME/2000/XP/Vista and Apple OS9.1/OSX computers with native USB support. No special drivers are needed.

Notes: Killer value two-channel mic and line pre-amp with 12AX7 valves to add analogue warmth. Great entry-level option for recording, processing or adding character during a mix.

Supplier's Notes:
Tubes can really warm up a signal fast, giving it increased depth and character. Though transistors have succeeded the technology, many musicians agree that tubes deliver a far superior sound. A true audiophile 2-channel Mic/Line preamplifier, the ULTRA GAIN PRO MIC2200's hand selected 12AX7 vacuum tube gives everything from microphones to acoustic or bass guitars that vintage tube vibe in a dependable and highly-affordable package. The onboard fully parametric EQs provide unparalleled tonal characteristics, allowing you to sculpt instrument and vocal sounds with the ultimate precision and musicality.

The MIC 2200 is perfect for studio and live applications. The balanced 1/4" TRS and gold-plated XLR inputs and outputs give you maximum flexibility in either scenario.

Notes: PreSonus have been designing preamps for a long time, and they always focus on audio quality first. So when PreSonus decided to upgrade their popular TubePre V2, PreSonus focused on improving an already high-quality soundiwithout jacking up the price. Like the original TubePre, the new version is a fully professional tube preamp, with a dual-servo (no capacitors) gain stage that lets you boost the program signal to smoking hot levels without significantly increasing the background noise. Discrete components and high-voltage operation offer dynamic range and detail not found in other single-channel tube preamps in its class.

But the TubePre V2 provides an even wider palette of sound options, and a much more focused tube saturation, than the original TubePre. It has been upgraded to employ PreSonus' popular XMAX Class A solid-state preamp, which is followed in the signal path by a 12AX7 vacuum-tube stage. Twist the TubePre V2 Drive saturation control to add the "color" that only a hand-selected 12AX7 vacuum tube can deliver i from gentle warmth to total fuzz.

Housed in a rugged case, the TubePre V2 rear panel sports separate unbalanced, 1/4" instrument and balanced, XLR mic inputs and unbalanced 1/4" and balanced XLR line outputs. PreSonus have included all of the extras you need for professional operation including a high-pass filter, phantom power for condenser mics, polarity reverse switch, and a backlit VU meter.

The TubePre V2 is more than a mic preamp, though. Thanks to its separate instrument and mic inputs, it also serves as a dynamite direct box (DI) for guitars and basses. And it's small enough to carry almost anywhere, although you also can screw-mount it to a standard rack tray.

So if you are a fan of PreSonus' original TubePre, you're going to love the improved TubePre V2. And if you are checking out the TubePre for the first time, your ears are in for a real treat. Then check out the amazing low priceibut sit down first because you're in for a shock. Because with PreSonus, big sound does not have to cost big bucks.
