Introduction

Congratulations on purchasing the Samson Servo Quad Amplifier! Although designed for easy operation, we suggest you first take some time to go through these pages so you can fully understand how we’ve implemented a number of unique features.

The Servo Quad Amplifier is actually four discrete power amplifiers in a single chassis, optimized for use in live performance, recording studios, and permanent installations. This manual covers two Servo Quad Amplifier models, which differ primarily in terms of their power rating: the Servo 4060, which delivers

60 watts per channel into 4 ohms (or, in bridged mode, 120 watts into 8 ohms) and the Servo 4120, which delivers 120 watts of power per channel into 4 ohms (or, in bridged mode, 240 watts into 8 ohms). Both models operate over the full frequency spectrum (from 20 Hz to 50 kHz) and include dual bridging switches, four sets of binding post (banana jack) outputs, and both electronically balanced 1/4" TRS and unbalanced RCA-type input connectors

Suggested applications for the Servo Quad Amplifier include:

•Bi-amping applications - Because it is actually four amplifiers in one, the Samson Servo Quad Amplifier is particularly well-suited (in conjunction with appropriate crossover circuitry) to power small and medium size bi-amped speaker systems.

•Amplification for main or nearfield monitors in both professional and project studios - Its superb audio specs and whisper-quiet performance (its convection cooling design means there is no fan) make the Servo Quad Amplifier the perfect complement to any recording studio.

•Home Theatre applications - The sheer flexibility offered by the Servo Quad Amplifier (four discrete amplifier sections plus two independent bridging switches) makes it the perfect addition to any home theatre, in conjunction with any DVD player or other surround sound system. For example, use two channels to drive your front left/right speakers and the other two to drive your satellite rear speakers. Or use two channels for your front left/right speakers and bridge the remaining two channels to drive your center channel or subwoofer with power galore—you’re limited only by your imagination!

•As an extension to a home hi-fi system - The Servo Quad Amplifier 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 Quad Amplifier’s inputs (thus using your hi-fi amp as a preamplifier) and then connect your existing speakers to the Servo Quad Amplifier’s outputs. If you fall in love with the sound (as we’re sure you will), you might want to sub- stitute 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 Quad Amplifier 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 Quad Amplifier can be used to drive stage monitors, allowing the performers to hear themselves without having to rely on onstage equipment amplification.

•MIDI rack monitoring - MIDI musicians can easily incorporate the Servo Quad Amplifier into their existing rack of gear. Combined with a pair of high quality stage or studio monitors, 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.

In these pages, you’ll find a detailed description of the many features of the Servo Quad Amplifier, as well as a guided tour through its front and rear panels, step-by-step instructions for setting up and using your Servo Quad Power Amplifier, a description of suggested applications, reference appendices, and full specifications. 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.
