SM Pro Audio TB202 2-Channel Tube Microphone Preamp/Compressor Reviews
10 out of 10
"Good buy."
Feature:
Simple yet has all the necessary features
Sound:
For a nice rich sound, turn up the INPUT knob very high ~9, turn up COMPRESSION knob (to 5 for vocals and 10 for acoustic guitar), and then turn the OUTPUT down low to reduce the volume to the final desired level. This drives the tubes, compresses the signal and give a nice rich sound. Use equalizer to bring the mids down a bit and perhaps add some highs. Excellent EQ section! The signal path listed here gives a very rich/expensive sounding mix for reasonable prices: SM58 Mic (channel 1) Taylor 714CE (channel 2) into SM TB 202 preamp/compressor into Behringer Mixer into QMS Power Amp into Mackie Speakers.

"$1,000 sound for a quarter of the price."
Feature:
The Equalization is the best feature. I like being able to adjust and equalize my microphone like a mixer. The only thing that it doesn't have is de-essing but this preamp sounds so clear I don't really think it even needs de-essing. I was really impressed.
Quality:
Nothing has broken on me yet. Everything looks built really well.Nice Maroon finish.
Value:
Excellent value, this definitely rivals the Focusrite optical preamps and is $400 cheaper.
Desirability:
This will bring you the big sound you have been searching for in professional recordings. You Want It!!!
Sound:
This product has an excellent smooth sounding compression. I tried it with the Behringer B-1 and it sounded exceptional for a budget microphone like that. The Slow Release setting is the best if you really want to make a certain instrument stand out.
Support:
Never had to contact them at all.
Overall:
I would definitely replace it with another one exactly the same. My recordings havent been better. I own an A.R.T. MP studio and that is retired in the closet forever.
