4Guided Tour - Rear Panel1: Fan - This variable-speed fan provides vital cooling to your S1500 / S2000 (the hotter the amp gets,the faster the fan blows!). Make sure that both the front and rear panels are kept free of all obstructionsand that cool, fresh air is accessible at all times. Also, try to ensure that the S1500 / S2000 is used in adust-free environment.2: Circuit Breaker - This circuit breaker will trip if there is a fault with the mains voltage or if maximumoutput is exceeded (very highly distorted). Push it in (once only!) to restart the amplifier.3: AC input - Connect the supplied heavy-gauge 3-pin “IEC” power cable here. Alternatively, thesupplied PowerCon™ connector plate can be attached here.4: Banana output connectors - Use these to connect each channel of the S1500 / S2000 to 4- or 8-ohm loudspeakers. Be sure to connect the loudspeaker correctly, with the red (+) terminal normallyconnected to the positive input of the speaker and the black (ground) terminal normally connected to thenegative input of the speaker. See page 7 in this manual for more information about Bridged mode andpages 8 and 9 in this manual for full speaker connection instructions.5: Speakon™ output connectors - Alternatively, you can use these to connect each channel of theS1500 / S2000 to 4- or 8-ohm loudspeakers. See page 7 for more information about Bridged mode andpages 8 and 9 for full Speakon™ connector wiring and interconnection instructions.6: Bridged / Stereo / Parallel switch - For normal operation, place this three-way switch in its center(“STEREO”) position. When placed in its right (“PARALLEL”) position, the signal arriving at theChannel 1 input only is routed to the power amplifiers of both Channel 1 and Channel 2 (the Channel 2input is ignored), with each power amplifier delivering 750 watts into 4 ohms (in the case of the S1500)or 1000 watts into 4 ohms (in the case of the S2000). When placed in its left (“BRIDGED”) position, thesignal arriving at the Channel 1 input only is again routed to both power amplifiers (again, the Channel 2input is ignored), but the two power amplifiers are bridged together, providing 1500 watts of power into8 ohms (in the case of the S1500) or a full 2000 watts of power into 8 ohms (in the case of the S2000).For more information, see the “Bridged and Parallel Modes” section on page 7 and the “S1500 / S2000Connections” section on pages 8 -9. WARNING: Due to the extremely high power output of theS1500 / S2000 when used in Bridged mode, be sure to use only loudspeakers sufficiently rated tohandle the resultant wattage (in Bridged mode, these must be 8-ohm speakers).7: Input connectors - Connect incoming signal to these electronically balanced Combinationconnectors, using either XLR or 1/4" TRS (Tip/Ring/Sleeve) plugs, wired as follows: Pin 2 (or Tip) hot,Pin 3 (or Ring) cold, and Pin 1 (or Sleeve) ground. We recommend the use of balanced three-conductorcabling wherever possible (unbalanced two-conductor 1/4" 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).The S1500 / S2000 accepts input levels of any strength but needs at least 0 dBu to achieve maximumpower. Stereo signals should be connected to both the Channel 1 and Channel 2 input jacks; however,when operating the S1500 / S2000 in Bridged or Parallel modes, use the Channel 1 input jack only.See page 7 in this manual for more information about Parallel mode and pages 8 and 9 in this manualfor full interconnection instructions.8: Link connectors - These XLR connectors provide unity gain outputs, allowing the S1500 / S2000 tobe daisy-chained to additional power amplifiers. Wiring is as follows: Pin 2 hot, Pin 3 cold, Pin 1 ground.See page 9 in this manual for more information.BRIDGED PARALLELSTEREOBALANCED0dBmCH 2 CH 1BALANCED0dBmINPUT~AC INPUT115V 60Hz, 1100W25A/250VPUSH TO RESET(4Ω~8Ω) (4Ω~8Ω)(4Ω~8Ω) (4Ω~8Ω)CH 2 CH 1OUTPUTTRSBALANCEDTIP=HOTRING=COLDSLEEVE=GNDXLRBALANCED3=COLD1=GND2=HOT42 11 73 5 6 8BRIDGED(8Ω~16Ω)PUSH PUSH
