It is a mono tube preamp: there is a small ECC83 (12AX7 =) in it. In fact a preamp is very simple: we gain, a low-cut filter, and a few other small spots. Mono jack or XLR connectors, one returns with an instrument or a microphone.

Ability to switch 48 volt phantom power supply. Rackable? It is a demirack, there may be a way to tinker with something ... maybe for the rack. The meter is there, and it emits a cool blue light ... it gives an ambience.

UTILIZATION

Very simple machine, when you have nothing else at hand that makes phantom power supply in order to register with a condenser microphone, that's the case. The manual is clear, but if we know the preamp is not needed.

SOUND QUALITY

A warm sound with a microphone Apex 430. The voices come out real nice with a small grain ... if you touch too small buttons at the bottom (low cut, eq. voice, etc.).

OVERALL OPINION

I use it for 3 months and the sound is up and running ...
The problem is that the phantom power supply dropped me ... ca c not cool ...
that's why I will change the preamp. but I keep this one to put it in insert.
I really like the sound.
