Hi,
Has anyone ever seen these? I'm thinking of replacing my SP-SPSB-1 battery box with a pair of these 'stick-on' mic preamps. The price is right (free) and I'm hoping they will be better than recording with the gain cranked up to +12dB on the JB3 followed by more post amplification in the computer.
My only concern is the low end of the range, 50hz, seems high. Isn't this number usually ~20hz? What effect will this have on the sound recorded using this pre-amp?
Right now I'm running a stereo SP gooseneck cardioid mics, battery box, and JB3. In the past I ran the battery box into a sony MD player at ~+25dB, but the JB3 only goes up to +12
Thanks for any help,
Todd in Buffalo

ANYWHERE YOU NEED...
Low-Noise mic preamp
Adjustable output levels
Hi or Lo-Z mic inputs
Mic input to Line Outputs
Two balanced or unbalanced outputs
Internal/External Phantom Capability
RF filtered inputs
You Need The STM-2!
APPLICATION: The STM-2 is a quality low-noise microphone preamplifier designed for use in commercial sound, broadcast, and recording. The STM-2 is very flexible, with gain adjustment from off to +65 dB, two balanced or unbalanced outputs, and available phantom supply input! Its ultra-low distortion and low-noise performance make it the best choice, even when larger preamps could be used! The single-ended supply input range is from 12 to 33 Vdc! Each output drives high or low impedance loads.
Typical Performance
Input Impedance: 150 to 600 ohm balanced; 5 kohm unbalanced
Output Impedance: 150 ohm balanced to drive balanced or
unbalanced lines 150 ohm or higher impedance
Gain: Adjustable 0 to +65 dB
Frequency Response: 50 Hz to 25,000 Hz +/- 1 dB

CMRR: greater than 60 dB (50 Hz to 30,000 Hz)
Headroom: greater than 20 dB (24 Vdc supply);
14 dB (12 Vdc supply)
Equiv. Input Noise: less than 140 dB
Power Requirement: 12 to 33 Vdc @ 25 mA, Ground-referenced
