4 channels. For a channel preamp gain, volume, a potion low cut, phase reverse.
Purely analog.
1 U rack

Microphone inputs and 2 outputs / channel. 1X jack-10dB and +4 dB XLR 1X usable simultaneously.

Entries in combos Jack / XLR mic / line / instrument and it was a dream come true with 10/10 :)


Simple Config? completely!
The manual is findable on the net at this link:


A very good sound that can be orientated according to its channel use.
Example: In the first 2-channel I 2 lamps mounted typed with a "nice" saturation (if desired!) For use via DI and recording guitar AND bass.
Channels 3 and 4 I mounted two lamps operating in pairs and equivalent but more transparent for overheads records gains.

The two types of configurations give VERY good results!


Used for some years now, I had a TL Audio 5050 Mono Mic Pre-Amp/Compressor and wanted to have more input.

Changing lamps can choose nervousness channel and the operation is easy.

+ + +: No breath and gain! (Comparison made with other preamp (MOTU, consoles, sound card ..)

---: The DI inputs on the preamp would be welcome for a small fee but it adds ...

If I found myself one and if I needed 4 additional inputs, I buy!
