CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN SONAMP 2120T HIGH CURRENT AMPLIFIER Congratulations on your purchase of this precision audio component and thank you for your selection of Sonance®. Your Sonamp has been designed with the latest technology to become the heart of the finest home theater and music systems. [. . . ] This permits you to know which wire you had connected to the + and which to the - speaker terminals so you can repeat these connections at the power amplifier terminals. OPERATING THE SONAMP 2120T The Sonamp 2120T has an ingenious and very sophisticated Auto On turn on/off circuit. Please read these instructions carefully to facilitate correct operating procedures. Power Switch Press the power switch once to the "in" position to turn on. Press again to the "out" position to turn it off. Leave the button in its inner position when using the Auto On turn on/off feature. The amplifier will switch its power on automatically when there is a musical signal present at its input jacks. Multiple Speaker Hookup The Sonamp® 2120T is stable into low impedances. If you are in doubt about your specific impedance load, consult your dealer or Sonance Technical Service. To connect more than one pair of speakers to the Sonamp 2120T, you will need to connect the speaker wires from each speaker in parallel. The safest and most efficient way to do this is to use dual-banana plug connectors which are plugged into each other, end-to-end. If you are connecting bare wires from each pair of speakers together, we recommend you make this junction at a point that is not immediately at the speaker terminals. This is because each joined bundle of wires will be too thick to fit into its speaker terminals and you run a risk of a short circuit between + and - terminals. You may use a Sonance SS6 or SS4 speaker selector. Auto-On Any audio signal arriving at the Sonamp's left input jack will trigger automatic turn on circuitry to activate the unit for operation. A green LED on the front panel marked "Active" indicates that the amplifier is operational. The amplifier will remain on after the audio signal has ceased for approximately 3 minutes. This provides ample time to prevent erratic operation from pauses between musical passages or while changing sources. With this feature there is no limit to where you can place the Sonamp. Here are a few installation possibilities: · Local room system coupled with a multi-CD changer · Surround sound front, side, or rear channels · Multi-room, multi-source control systems Use good wire For best results, and minimum power loss, you should never use thin gauge speaker wire - it will constrict the sound and deteriorate bass response. We recommend use of premium Sonance speaker cable. You may also wish to experiment with audiophile-grade speaker wire and interconnects, but be sure to check local codes governing wire that may be installed in walls or ceilings. Each brand of wire will have a different characteristic sound and some may be more compatible with the sonic "signature" of your various components. Your Sonamp is stable with any reputable brand of wire. Auto-On Defeat (located on rear panel) If the Auto-On turn on/off feature is not required, it can be defeated by moving the rear panel switch to its "off " position. Use a small flat-bladed screwdriver to move the recessed switch. Now the Sonamp power switch will function conventionally and the Sonamp will turn on and off from a switched AC outlet on your preamp or other source component. AC Line cord You can plug this into a wall socket or an AC outlet on your preamplifier.
