UTILIZATION

The configuration could not be easier! Not need the manual ...
Out of the box connect, test, and off you go!

SOUND QUALITY

I use it to amplify my microphones and instruments before going into my sound card Terratec Phase88.
The sound is very clean and I see no breath!
I do not have to get the gains to get a good reception (Some milimettres enough).

OVERALL OPINION

I use it for two weeks just so I can not give advice on longevity.
What I like most is the price! € 150 is really not steal!
Then the phantom power on each track separately controllable it is still the foot!
What I like least? ... Heuuuuuu ... Beinnn heuuuuu ... How to say ... Knobs may be plastic but hey, I do not see what the problem is ...
Before using this preamp, I used a Behringer Eurorack mixing desk, which broke down 3 times and whose control of the phantom was small (two point) ...
Frankly this preamp is really worth!

Octo pre amplifier with each channel:
- Gain (knob rotary)
- A button on / off +48 V phantom power
- A phase inversion button.

Enter by 8 combo facade (XLR/jack6, 35)
output jack 8 6.35 in rear

Inter 1 On / Off Front

Rackable 19 "/ 1U

UTILIZATION

Basic, nothing to say: Ultra Simple
1 Knob gain and that's all

biensur must activate the phantom power if needed, or reverse phase if necessary.

SOUND QUALITY

These transistor preamp.

Adds no breath earlier neutral short, he did his job.

but nothing more (it's not high end)

OVERALL OPINION

I've had 4 years, I do not use it much.
It is a sound card to 8 inputs (Terratec Phase88), history of having correct preamps that accept microphone, even electro static.
