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-standing or mounted in a standard 19" rack, requiring only two rack spaces. When installed, make sure that there is good ventilation around the entire unit (we recommend using spacer panels, especially if multiple amplifiers are used in a rack. Before rack-mounting, use a Philips screwdriver to attach the included rack ears.

2.Set either or both rear panel Bridge switches as desired (see page 7 in this manual for more information).

3.Make the speaker connections, using the binding post (banana plug) output connectors on the rear panel. It is never a good idea to power up any amplifier that is not connected to loudspeakers. In normal modes of operation, any loudspeakers with a minimum impedance load of 4 ohms (that is, 4 ohms or greater) can be used; however, in Bridge Stereo mode, 8 ohm speakers must be used. Be sure to connect the loudspeaker correctly. In normal mode, connect them with the red (+) terminal connected to the positive input of the speaker and the black (-) terminal connected to the negative input of the speaker. Refer to page 7 in this manual for connection instructions when using the Servo Quad Amplifier in Bridge Stereo mode. If you are using the Servo Quad Amplifier for bi-amping applications, refer to the “Bi-amplifica- tion Applications” section on page 8 in this manual for more information.

4.Next, make the signal input connections, using the electronically balanced 1/4"

and/or the unbalanced RCA-type input connectors on the rear panel. If your mixer or crossover network has balanced outputs, use the Servo Quad Amplifier’s electroni- cally balanced inputs (unbalanced two-conductor plugs can also be inserted into these inputs, but you’ll get better signal quality and less outside noise and hum if you use balanced lines). If you are using the Servo Quad Amplifier for bi-amping applica- tions, refer to the “Bi-amplification Applications” section on page 8 in this manual.

5.On the front panel of the Servo Quad Amplifier, turn all four Channel input controls fully counterclockwise (to their “∞ ” setting). Then connect the supplied 3-pin “IEC” cable to the rear panel IEC connector and to any grounded AC socket. Because of the relay protection circuitry built into the Servo Quad Amplifier, you can even plug it into the same power strip that other audio devices (such as a mixing console) are connected to. You can then turn on all devices at once with the single power strip on- off switch, with no danger of damaging connected speakers by generating “thumps.”

6.Press the front panel Power switch in order to turn on the Servo Amplifier.

The Power LED will light and the two Protection LEDs will go on for approximately five seconds, and then switch off (you’ll hear a click when they do so).

7.Apply an input signal to the amplifier at or about 0 dbM (if sending signal from a mixer, drive the output meters at approximately 0 vu). While the input signal is present, slowly raise the Channel input controls until the desired sound level is achieved. The five-segment LED meters above each Channel input control will show you the continuous power output of the Servo Quad Amplifier as signal is being passed. For the best signal-to-noise ratio, the Servo Quad Amplifier should normally be run with the Channel input controls at or near maximum (fully clockwise, at the “0 dB” position) and the right-most (CLIP / 100%) segment should light occasionally (but not frequently) during peak levels. If you are using a mixing board that has a master output level control (sometimes called “control room level”), use it to attenuate the signal as necessary to achieve the desired speaker level.

If you encounter difficulty with any aspect of setting up or using your Servo Quad Amplifier, you can call Samson Technical Support (1-800-372-6766) between

9 AM and 5 PM EST.
