Modular amplification

and professional applications
3B SST
The 3B SST stereo amplifier, at 150 Watts per channel, provides all the sonic
virtues and the same high value as our more powerful 4B SST but in a package
which is both compact and less costly. Historically, the 3B has found favor in a
wide range of audio/video systems which call for only moderate amounts of
power but wish to avoid sacrificing sonic accuracy and long-term reliability.

status — green for power-on, red
for overdrive.
“Electronic” front panel membrane
power switch (no moving parts); rear
panel toggle power switch doubles as
circuit breaker reset (no fuses).
Modular design with
independent power
supplies each with its
own transformer for
precise sound-staging.
Quick-connect 12 Volt trigger
input allow remote on/off
triggering of your amplifier(s).
SST Input flexibility: XLR or 1/4”
phone jack for balanced signals and
RCA jack for single-ended source;
