Variable impedance microphone preamp, Mic / Line tube direct box, a half rack. The solid, 3.7 kb! The buttons a bit fragile perhaps, but do with time ...!
The 2BA-221 offers entry-level microphone, line level and high impedance instrument and uses input controls transistor separate and independent to mix the microphone input with the input line or instrument input to the output tube . We can combine these signals to the output tube 12AX7A/ECC83 or separately by the individual output transistor.
Possibility of multiple 2BA-221 assembly line.
Connections: XLR in (or with a 0-20dB pad) and out (+4 db) symmetric, Jack high impedance (Hi-Z) in and out (-10db) symmetric. Possibility of an effect insert.
Also an input / output "Stack" for the entry is the asymmetry "which Sums Into the 2BA-221 Just Before the tube output stage and insert jack ".... And for the exit" Stack " is the asymmetric linker which allows two machines together ... I have not quite understood that part ...! It looks great even when full!
Staining with the lamp, plus a high pass filter 20 Hz - 200 Hz mutable, and impedance setting for the microphone.
UTILIZATION
For a first outlet, no problem, a microphone, an output is switched on 48v, turn (slightly!) The gain knob, and power is! The output 4 db surprises! It saturates very quickly if not careful ... I used mainly for instant output-10db to balanced jack.
Turning the button "Tube Output" to color everything, it's easy, there's more experience!
One thing that is very well thought out, is that you can have 4 different outputs for the same decision, including a pre-amplification for the lamp to a 4dB, another at-10db, etc ... at the same time! Very useful for making a backup in case the db 4 saturates!
Another great plus point, we can invert the phase with a small button "polarity"!
So, everything is good!
SOUND QUALITY
No problems for the reproduction of sound! I could not test so for now, but the difference with my MindPrint Di-Port (even if the preamp is pretty good forthe price) is pretty gross! The sound is much more ... hum .... present! in all frequencies in the treble, bass, really mean things that were not there before!
I would do an edit later!
The preamp is transparent if we use too the lamp and filter. But the heat is already gone! No color too strong for my taste. Just enough!
OVERALL OPINION
Ordered on Tuesday morning at Thomann (577 euros instead of 730 in France !....), I received ........ Wednesday morning! Well, I live in Alsace, it's not far, but still!
I could not test it this evening very quickly on a drum overhead (well, I know it's not terrible, but I had nothing else to hand!), And good, the difference is compared to what I had before!
I could not test other devices to compare, I have a lot to make me ride a notice (not necessarily) target, compared prices, connectivity, reputation, etc ...
Assets:
Very complete
Very good sound reproduction with a little warm color very nice, but that does not distort the sound (unless of pushing the button Tube Output at max!)
The price!
The price!
and 3 years manufacturers warranty (Thomann and for that matter!)
Cons:
Bah, I would have liked it to be stereo for the same price!
4 db output that requires a good converter that much cash back!
That's it!
Price / quality ratio very good, but mono ... is perhaps the Goldmike (first name) who did very well also ... but less complete in my opinion.
I plan to buy a second by a few times if j'accrche really well, and I think it is left for!!
