6ENGLISH7 CONNECTIONS• Do not plug in the AC cord until all connections have beencompleted.• Be sure to connect the left and right channels properly (leftwith left, right with right).• Insert the plugs securely. Incomplete connections willresult in the generation of noise.• Note that binding pin plug cords together with AC cords orplacing them near a power transformer will result ingenerating hum or other noise.• Noise or humming may be generated if a connected audioequipment is used independently without turning thepower of this unit on. If this happens, turn on the power ofthe this unit.(1) Speaker system connections• Use speaker cords with twisted wire cores and a diameterof 0.6 to 1.5 mm. Never use cords thicker than 1.5 mm orsingle-wire cords, as they may damage the speakerterminals.• Be sure to interconnect the polarities of the terminals on thespeakers and main unit (≈ to ≈, √ to √).• When making connections, be careful that none of the corewires of the speaker cords stick out and touch neighboringterminals, other speaker cords or the rear panel.• Speakers with an impedance of 6 to 16 Ω/ohms can beconnected for use as center and surround speakers.NOTE:NEVER touch the speaker terminals when the power ison.Doing so could result in electric shocks.• The protector circuit may be activated if the set is played forlong periods of time at high volumes when speakers with animpedance lower than the specified impedance areconnected.Connection the speaker terminals1. Push the lever. 2. Insert the cord. 3. Return the lever.2 Connect using the speaker cords included with the USYS-1000.Be sure to turn off the power of the ADV-1000 whenconnecting the speaker units to it.• Use the included speaker cords to connect the inputterminals on the backs of the speaker units (see diagram atright) to the speaker output terminals on the ADV-1000.Note that if the polarities are not properly interconnected,the phase may be off and the sound may be unnatural (nobass).NOTE:DO NOT touch the speaker terminals when the power is on.Doing so could result in electric shock.SPEAKER SYSTEMS6 16 R LIMPEDANCECENTERSURROUNDR LFRONTSUBWOOFER INV.AUX OUTINTV/DBSDIGITAL(OPTICAL)IN OUTININTV/DBSINV.AUX VCRMON.OUTS VIDEOIN OUTININTV/DBSINV.AUX VCRMON.OUTVIDEORLIN OUT IN ININ OUTV.AUXTV/DBS VCRCDR/TAPEPRE OUTSUB WOOFERAMFM COAX. 75LOOP ANT.AUDIOY C BCOMPONENT VIDEO OUTC RSuper woofer(USW-1000)Surround speaker(USC-A1000)(L) (R)Speaker cord B (length:approx. 3 meters)(included)Speaker cord A(length: approx.10 meters)(included) Speaker cord A (length:approx. 10 meters)(included)Speaker cord B(length: approx.3 meters)(included)Speaker cord B (length: approx. 3 meters)(included) Speaker cord B (length: approx. 3 meters)(included)(L) (R)Front speaker(USC-A1000)Center speaker(USC-C1000)Front speaker(USC-A1000)
