AC Line Connection Before you attach the AC cord, make sure the ZAMP power switch is in its off position. We recommend that you use only this cord and try to make direct connection to the AC wall outlet. Input Connections Use the right and left channel RCA jacks for stereo operation. For bridged mono operation, use only the right channel input jack and leave the left channel jack disconnected. Speaker Connections -- General Recommendations You may use 4 - 8 rated speakers for stereo operation. We do not recommend lower impedance loads, because they may cause overheating and activate one of the protection circuits. The speaker terminals of the ZAMP will accept 1/4" spade lugs, dual or single-banana plugs or bare wire up to 12 AWG. For best results you should never use speaker wire thinner than 16 AWG. If you use bare wire without plugs, make sure you strip off only enough insulation so the bared wire fits through the hole that runs sideways through the terminal's metal shaft. Before inserting the wire, twist all its strands tightly to prevent strays that could cause a short circuit between + and - terminals. You may want to "tin" the stripped wire with solder to prevent it from fraying. One side of the speaker wire will have some sort of mark such as printing, a raised ridge on the insulation or a different color conductor. This lets you know which wire to connect to the + and which to the - speaker terminals so you can make the same connections to the 5 way binding posts on the Zamp. Mono Bridge Switch Set the bridge switch to normal Stereo (up) or Mono Bridged (down) operation as marked on the rear panel. Make sure the power is off to the ZAMP before changing this switch position. If you accidentally leave the Mono Bridge switch in the Mono position for normal stereo listening, you will find stereo output will be very weak and distorted. Bridged Mono Operation When mono bridging your Zamp, do not connect a speaker with an impedance lower than 8 because in the bridged mode, each channel effectively "sees" only half of the speaker's actual impedance. For a 4 speaker, the impedance would be 2 per channel which is too demanding on the amplifier. [. . . ] Fingerprints may be removed with a soft cloth moistened with clean water or window cleaner. In Case of Trouble If you suspect a problem with this unit, contact your authorized Parasound Dealer or Installer, or call Parasound Technical Services. We may be able to suggest diagnostic tests you can easily perform that may save you a lot of trouble. If we determine that your ZAMP should be returned to Parasound or an Authorized Warranty Center for inspection and possible servicing, call for the location of a Warranty Center near you. [. . . ]
