ARCHITECT’S & ENGINEER’S SPECIFICATIONS
The Samson Servo 300 shall be a two space rackmount
stereo power amplifier. It shall deliver 150 watts per channel
at 4 Ohms or 300 watts into 8 Ohms in bridge mono mode.
It shall have 1/4 inch balanced inputs and RCA unbalanced
inputs. It shall be a bi-polar design and use a toroidal
transformer. The front panel shall have volume controls and
LED metering for each channel. The rear panel shall also
have 5 way binding posts for the amplifier outputs.

FEATURES

>
10 segment LED signal indicators for each channel
continuously display power output levels and allow you to
correct for overloading (clipping) conditions.
correct for overloading (clipping) conditions.
>
Unique stable bipolar circuit design that continuously
keeps DC output during idling at or near zero volts (thus
keeping idle speakers at their zero point). This serves to
minimize heat overload problems by effectively preventing
the Servo Series from applying power when unnecessary.

Protection relay circuitry (with dedicated LEDs for each
channel) that guards against overheating or faulty wiring
conditions and also prevents “thumps” when powering on or
off. This means that you can use the Servo 300 with a single
power strip into which a mixer or other audio devices are
connected, without danger of damage to connected speakers.
