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 fuse here for 115 volt operation, or a 6.3 amp, 250 volt fuse for 230 volt operation. We recommend the use of normal (as opposed to slow-blow) fuses. WARNING: Fuses should only be replaced with the power cord disconnected.

3:Binding post (banana jack) output connectors (Ch 1 - 4) - Use these to connect each channel of the Servo Quad Amplifier to loudspeakers. Be sure to connect the loudspeaker correctly, with the red

(+) terminal normally connected to the positive input of the speaker and the black (-) terminal normally connected to the negative input of the speaker. See the “Bridge Stereo Mode” section on page 7 in this manual for speaker connection instructions when using the Servo Quad Amplifier in bridge mode.

4:Balanced Inputs* (Ch 1 - 4) - Connect incoming signal to these electronically balanced 1/4" TRS (Tip/Ring/Sleeve) jacks, wired as follows: Tip hot, Ring cold, and Sleeve ground. Use balanced three- conductor cabling and TRS plugs wherever possible (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). Note that the Servo Quad Amplifier balanced inputs are 6 dB higher in gain than the balanced inputs (see #5 below). The Servo Quad Amplifier accepts input levels of any strength but needs at least 0 dBm to get maximum power.

5:Unbalanced Inputs* (Ch 1 - 4) - Connect incoming signal to these unbalanced RCA-type jacks. The Servo Quad Amplifier accepts input levels of any strength but needs at least 0 dBm to achieve maximum power. Note that the Servo Quad Amplifier unbalanced inputs are 6 dB lower in gain than the balanced inputs (see #4 above).

6:Bridge switch - For normal operation, place this switch at its left (“OFF”) position. When placed at its right (“ON”) position, each of the two amplifier sections (channel 1 and channel 2 and/or channel 3 and channel 4) are bridged, providing full 120 or 240 watt power output, depending upon the Servo Quad model you’re using. For more information, see the “Bridge Stereo Mode” section on page 7 in this manual. WARNING: Due to the extremely high power output of the Servo Quad Amplifier when used in Bridge Stereo mode, be sure to use only 8 ohm loudspeakers sufficiently rated to handle the resultant wattage.

* If required, both the balanced and unbalanced inputs can be used simultaneously.
