Thank you for purchasing the Servo Series Power Amplifier from Samson Audio! We know you don’t like reading own-

ers manuals, but you’ve just purchased one of the finest sound reinforcement power amplifiers around, and we want

to tell you about it. So, before you plug in, we’d like to suggest you take just a few moments out to scan these pages.

We’ll make it as painless as possible, we promise—and, who knows, you might just pick up a tip or two.

The Samson Servo Series stereo power amplifiers have been designed to provide robust, clean output with low distor-

tion and wide dynamic range, along with the dependability demanded by the most professional audio engineers and

Their convenient 2 rack-space design is compact, and yet there’s plenty of power available, with 2 x 66 Watts at 8Ω, 2

x 100 Watts at 4Ω for the Servo 200, 2 x 100 Watts at 8Ω, 2 x 150 Watts at 4Ω for the Servo 300, 2 x 225 Watts at 8Ω, 2 x

300 Watts at 4Ω for the Servo 600, over the full frequency spectrum, from 10 Hz to 55 kHz.

the outputs, the Servo Series amplifiers provide standard 5-way binding posts and 1/4” phone jacks. Front-panel con-

trols 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 Series amplifiers include front panel Signal, Peak

amplifiers running cool, their

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-

demanding situations.

The

You’ll also find a warranty card enclosed—please don’t forget to fill it out and mail it in so that you can receive online

technical support and so we can send you updated information about these and other Samson products in the future.

SPECIAL NOTE: Should your Servo Series ever require servicing, a

number (RA) is necessary.

Without this number, the unit will not be accepted. If purchased in the United States, please call Samson at 1-800-372-

6766 for a Return Authorization number prior to shipping the unit. If purchased outside the United States, contact

your local Samson dealer for details. Please retain the original packing materials and, if possible, return the unit in its

original carton and packing materials.

all 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 fre-

quency response of 10 Hz to 55 kHz guarantee ultra-clean sound quality.

• Independent input level controls for each channel allow precision adjustments.

• 10 segment LED signal indicators for each channel continuously display power output levels and allow you to 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.

• Forced air cooling via two temperature-sensitive, variable speed fans provides reliable performance without thermal and

overheating problems.

• 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 Series with a single power strip

• Input connectors for each channel accommodate both RCA or balanced 1/4-inch TRS plugs.

• Output connections are made via 5-way binding posts

• Toroidal transformer power supply for high current and low profile.

• User-resettable circuit breaker for fast, easy startup following a power supply overload.

• The Servo Series can be mounted in any standard 19" rack (taking just two rack spaces), making it easy to integrate the amp

• Rugged construction (an all-steel chassis with a cool gray finish and a lightweight anodized aluminum heat sink) makes the

Servo Series eminently roadworthy.

• Extended three-year warranty.

• Last but certainly not least, value. The Samson Servo Series has been designed from the ground up to deliver excellent yet

affordable sound quality
