GENERAL DESCRIPTION
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:
• 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.
• 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
satellite speakers—or use the Servo 120a in Bridge mode to
drive your center channel or subwoofer with power galore.
• 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.
• 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.
• 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.
