7 INSTALLATION & CONFIGURATIONSAFETY NOTE: When making connectionsbetween any source components suchas AV receivers, surround processors ormultiroom controllers and the PA 2000,or when making any connections tospeakers, be certain that both the sourcedevice and the PA 2000 are turned off. Toensure that there will be no unwantedsignal transients that can damage equip-ment or speakers, it is always best tounplug all equipment before making anyconnections. Modern electronic productsoften have a “standby” mode that maybe activated even though the productmay appear to be turned off.Power Control ConnectionsThe PA 2000 features a built-in remote turn-onsystem that will automatically turn on either orboth of the amplifier pairs in one of three ways.Depending on your specific application, the unitmay be turned on manually using the PowerSwitch 1, or via automatic sensing of eitheran input source or a low-voltage trigger signal.For manual operation, no special installation isrequired. For automatic turn-on, follow theinstructions below for the chosen triggermethod.Note that when the unit is operated in thestandard, two-pair output mode, each of thechannel pairs may be operated by the sametrigger method, or they may be turned on viadifferent methods.Remote Turn-On From an External DeviceUsing the Low-Voltage TriggerTo configure the PA 2000 so that either or bothof the channel pairs turn on automatically inresponse to a low-voltage trigger signal, followthese steps:1. Place the Power Control Mode Switch£ for either channel in the center position,so that the switch is over the words “AC/DCTRIGGER”.2a.To trigger the amplifier from a device suchas a preamp surround processor or multi-room controller with a built-in trigger jack,connect one end of a cable with a 3.5mmmono mini-plug to the Trigger Jack § onthe PA 2000. Connect the other end to amatching jack on the device that will pro-vide a 3-volt to 30-volt signal when the unitis to be turned on.or2b.To trigger the amplifier using the switchedAC accessory outlet on an AV receiver orother source device, purchase a small AC toDC power converter, as is typically used toreplace the batteries in portable electronicsdevices. Select a model that is capable ofdelivering 3 to 12 volts DC, and make cer-tain that one of the “tips” provided with theunit is a 3.5mm mini-plug. Plug the trans-former end of the converter into theswitched AC output on the source product,and connect the 3.5mm mini-plug to theTrigger Jack §.3. Press the Power Switch 1 in so that it isengaged, and note that the StandbyIndicator 3 will light for the channel pairsselected for trigger control operation.When the source control unit providing thepower is turned on, the PA 2000 will automati-cally turn on. When the source unit is turnedoff, the PA 2000 will return to the Standbymode.Remote Turn-On Using Music SenseTo configure the PA 2000 so that either or bothof the channel pairs turn on automaticallywhen the amplifier is receiving an audio signal,follow these steps:• Connect the audio input as normal to theaudio Input Jacks ¡.• For each channel pair that you wish to con-trol using an incoming audio signal, slide thePower Control Mode Switch £ to thefar left so that the switch is under the words“MUSIC SENSE”.• Press the Power Switch 1 in so that it isengaged, and note that the StandbyIndicator 3 will light for the channel pairsselected for trigger control operation.In this configuration, the PA 2000 will automat-ically turn on whenever it is receiving an audioinput signal. The unit will return to the Standbymode 10 to 15 minutes after the audio signalstops.NOTE: When the PA 2000 is used in theBridged mode as a single-pair stereo amplifier,use the Power Control Mode Switch £ inthe area labeled “BRIDGE/CHANNEL ONE” tomake the settings for the desired turn-on mode.Installation and Configuration
