3 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...

4 servo quad amplifier features the samson servo quad amplifier utilizes the latest technology in professional power amplifier design. Here are some of its main features: • power to spare - each channel of the servo 4060 delivers 60 watts into 4 ohms (or, in bridge stereo mode, 120 watts into 8 ohms...

6 guided tour - rear panel 1: ac input - connect the supplied standard 3-pin “iec” plug here. 2: fuse holder - in the servo quad 4060, insert an 6 amp, 125 volt fuse here for 115 volt operation, or a 3.15 amp, 250 volt fuse for 230 volt operation. In the servo quad 4120, insert an 8 amp, 125 volt fu...

7 setting up and using the servo quad amplifier setting up your servo quad amplifier is a simple procedure which takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service) and decide where the amplifier is to be physically placed—it can be used free-stan...

8 the servo quad amplifier protection circuitry as noted in the “guided tour” section of this manual, the servo amplifier's front panel protection lights indicate the activity of the relay speaker connection circuitry. When the protection lights are lit, this circuitry is inactive, and all connected...

Bridge stereo mode the servo quad amplifier provides two rear-panel switches that allow it to be used in a unique bridge stereo mode. When these switches are in their “off” (left) position, the servo quad amplifier functions as a true quad amplifier, where each of the four independent amplifier chan...

Bi-amplification applications because the samson servo quad amplifier actually contains four discrete power amplifiers in a single chassis, it is particularly well-suited for use with bi-amped speaker systems. These systems utilize active crossover networks (sometimes called electronic crossovers) t...
