User manual SONANCE SONAMP2120T INS

[. . . ] Its high power output is matched by enormous current capacity to drive multiple pairs of high quality speakers. Please take a few moments now to read these instructions thoroughly so you may fully understand the sophisticated capabilities of your new power amplifier. IMPORTANT SAFETY INSTRUCTIONS 1. Read instructions - All the safety and operating instructions should be read before the appliance is operated. Retain instructions - The safety and operating instructions should be retained for future reference. [. . . ] Please read these instructions carefully to facilitate correct operating procedures. Power Switch Press the power switch once to the "in" position to turn on. 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. 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. 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. Make sure your preamp outlet rating is equal to or greater than the Sonamp's power consumption rating. If you do not plan to use the automatic turn on/off feature, you will probably want to use a switched AC outlet that is turned on and off by your preamp's power button. [. . . ] To keep clean use only a soft cloth and never use any solvents or abrasives. Fingerprints may be removed with a soft cloth moistened only with a few drops of water.
