High Mu
Published on 05/26/04 at 06:36
Transistor preamp mono Class A / B (not class A).
Circuit Parallel tube (12AX7 triode 1).
The contribution of the lamp can be adjusted from there, until a saturation important.
Two amplification stages: 1 to 45dB before the lamp circuit and a 15dB after.
A balanced XLR microphone input
A high impedance instrument input jack TS
An insert point
1 balanced XLR output
1 TRS balanced output
the two outputs are used simultaneously, it is possible to "split" a signal with VTB1 (interesting)
Low-cut filter at 75Hz, 18dB per octave.
Phase inverter
phantom power
Small (too) LED level meter with the ability to view the level of the first amplifier stage, or the output of preamp.
Impedance selection switch for the microphone input (50/200 ohm)
SP sells a kit for the rack VTB1 2.
Complete, all that.
UTILIZATION
Complete connectivity. Good point.
I use the input of the lamp rather limited, I do not push the knob to more than 11 hours.
Used sensibly, it's good, it is a smooth sound. But I do not like the pressure, saturation made then no longer very musical.
I used to microphones, in DI for bass, for a signal splitter ...
The display is too small.
Easy to use, manual unnecessary. Bad point for the display (still usable)
SOUND QUALITY
For this price, the sound is OK.
The VTB1 is logically better than the preamps of my Soundcraft M12, but not as good as my SPL Goldmike (less neutral, less broad, less accurate, less defined).
It's hard to define, but I find the sound fairly bright. The contribution of the lamp to smooth this one is "stiff."
Strange to VTB1 I prefer my Goldmike to some sources, note the bass drum with a Shure Beta52A!
In DI, it is fair to good on some sources, but never better.
OVERALL OPINION
I have 2 from a can under a year.
Qualitée price OK.
Rather well built, it air relatively strong for the price range.
It will not replace a high end preamp, but s'acquite its role well, and will advantageously replace a preamp table "home studio".
