GENERAL DESCRIPTION  
satellite speakers—or use the Servo 120a in Bridge mode to  
drive your center channel or subwoofer with power galore.  
The Servo 120a is a single rack-space stereo  
power amplifier which is optimized for use in both  
professional and project recording studio environments  
as well as for live performance. It delivers 60 watts  
of power per channel into 4 Ohms (or, in Bridge  
mode, 120 watts into 8-Ohms) over the full frequency  
spectrum, from 3 Hz to 65 kHz. Both balanced 1/4˝  
TRS and unbalanced RCA-type input connectors  
are provided, along with 5-way binding post output  
connectors. Front-panel controls and displays include  
a power switch, independent left- and right-channel  
input level controls, ten-segment LED meters, a  
Protection LED, and a convenient headphone jack  
and speaker on/off switch for private cue monitoring.  
Suggested applications for the Servo 120a include:  
• As an extension to a home hi-fi system - The Servo 120a  
boasts professional specs which far exceed that of most  
consumer products. For a real “studio” experience in  
your own home, try connecting your home hi-fi amplifier’s  
auxiliary outputs to the Servo 120a’s inputs (thus using  
your hi-fi amp as a preamplifier) and then connect your  
existing speakers to the Servo 120a’s outputs. If you fall  
in love with the sound (as we’re sure you will), you might  
want to substitute a professional pre-amplifier for your  
existing hi-fi amp—and, from there, you may well end up  
graduating to higher-level speakers. High quality sound is  
addicting—don’t say we didn’t warn you!  
• Powering public address systems in permanent installations -  
The Servo 120a can be used to effectively drive PA  
speakers in installations such as classrooms and corporate  
conference rooms.  
• Amplification for nearfield monitors or cue  
headphones in both professional and project  
studios - Its superb audio specs and whisper-quiet  
performance (its convection cooling design means  
there is no fan), along with its unique front-panel  
speaker on-off switch and dedicated headphone  
jack, make the Servo 120a the perfect complement  
to any recording studio.  
• Onstage monitoring - In small and medium-sized onstage  
areas (such as in clubs, lounges, etc.), the Servo 120a can  
be used to drive stage monitors, allowing the performers  
to hear themselves without having to rely on onstage  
equipment amplification.  
• Home Theatre applications - The power and flexibility  
offered by the Servo 120a (it can be used either as a  
60 watt stereo amplifier, or, in bridge mode, as a 120  
watt monophonic amp) makes it the perfect addition  
to any home theatre, in conjunction with any DVD  
player or other surround sound system. For example,  
use it in stereo mode to drive your main front left/right  
speakers, using your home stereo to drive the rear  
• MIDI rack monitoring - Taking only a single rack space,  
MIDI musicians can easily incorporate the Servo 120a into  
their existing rack of gear. Combined with a pair of high  
quality stage or studio speakers, this makes for an excellent  
monitoring system that can accurately reproduce the broad  
range of frequencies typically output by devices such as  
synthesizers, samplers, and digital audio workstations.
