GENERAL DESCRIPTION
The Samson Servo 300 stereo power amplifier has
been designed to provide robust, clean output with
low distortion and wide dynamic range, along with
the dependability demanded by the most professional
audio engineers and installers.
Their convenient 2 rack-space design is compact,
and yet there’s plenty of power available, with 2 x
100 Watts at 8Ω, 2 x 150 Watts at 4Ω over the full
frequency spectrum, from 10 Hz to 55 kHz.
For mono applications, a Bridge mode links both
channels of the amplifiers, thus providing even more
single channel power, with a power ratings of 300
watts into an 8 Ohm load.
Input connections are available for both unbalanced
RCA connections and balanced 1/4-inch TRS
connections. For the outputs, the Servo 300 amplifier
provides standard 5-way binding posts and 1/4
˝
phone jacks. Front-panel controls and displays
include a power switch with LED indicator, as well as
independent left and right channel input level controls.
To help you set the correct operating levels, the Servo
300 amplifier includes front panel Signal, Peak and
Protection LED indicators. There's also a ten-segment
VU meter to help you set a good operating level.
Like all serious power amplifiers, the Servo 300’s
internal electronics are based around a serious power-
core, with a over-sized toroidal transformer and large
extruded heat sinks. To keep the Servo 300 amplifier
running cool, the design employs twin internal wind tunnels
with forced-air cooling via two temperature-sensitive, variable
speed fans, which greatly reduce the chance of thermal and
overheating problems. Multi-stage protection for power-up,
over-heating, over-current, short circuit, low output impedance
and DC voltage, assures high reliability under the most
demanding situations.
The Servo 300 amp is road tough with its all steel chassis and
19-inch rack mount design. The Servo 300 amplifier is ready
for a life on the road, or to make its home in a fixed installation.
Optimized for live sound venues, houses of worship, commercial
installations, and for driving small and medium-sized live PA
systems, the Servo Series amplifiers will deliver reliable power
from gig-to-gig, venue-to-venue and day-to-night.
FEATURES
> Power to spare - 2 x 100 Watts at 8Ω, 2 x 150 Watts at 4Ω
> For mono applications, a Bridge mode links both channels
of the amplifiers, thus providing even more power, with a
power rating of 300 watts driving an 8 Ohm load.
> Clean, crisp sound - Impressive audio specifications such
as 0.04% THD, dynamic range of 105 dB, crosstalk
of 80 dB, and frequency response of 10 Hz to 55 kHz
guarantee ultra-clean sound quality.
> Independent input level controls for each channel allow
precision adjustments.
