30INSTALLATIONrequirements of all applicable state and local building codes, aswell as NEC (National Electrical Code) requirements. Check withyour local authorities as needed to ensure that all wiring insidewalls is installed in compliance with the proper standards. Failureto do so may present a potential safety hazard. If you have anydoubt about your ability to work with electrical and telecommuni-cations wiring, you are advised to hire a professional licensedelectrician or custom installer to install the multiroom system.1. Connect the remote room’s speakers directly to the SurroundBack/Multiroom Speaker Outputs. See Figure 37.Figure 37 – Surround Back/Multiroom Speaker OutputsIf you do not require a full 7.1-channel system in your main listeningarea, and you prefer not to purchase an external amplifier to powera pair of remote speakers, you may reassign the AVR 247’s SurroundBack amplifier channels to power the speakers. Your main system willbe limited to 5.1 channels, which affects your ability to enjoy themany DVDs and other programs recorded in 6.1 and 7.1 channels.2. Connect an external amplifier to the Surround Back/MultiroomPreamp Outputs. See Figure 38.Figure 38 – Surround Back/Multiroom Preamp OutputsThis method may be used when it is more important to distribute audioto additional rooms than to have a full 7.1-channel system in the mainlistening area, as it is still necessary to assign the surround back amplifierchannels to the remote zone, limiting the main system to 5.1 channels.This method also requires you to provide an additional component, thatis, the amplifier. However, this method may be used to increase thenumber of remote rooms in the system when you are also using theSurround Back/Multiroom Speaker Outputs.It is recommended that you place the amplifier in the same room asthe AVR 247 so that a shorter length of interconnect cable is used witha long run of speaker wire to the remote room, rather than placing theamplifier in the remote room, which necessitates a long run of intercon-nect cable that would then be subject to signal degradation. Dependingon the number of channels available in your amplifier, you may distributethe AVR 247’s analog audio signal to a single pair of speakers for two-channel listening, to several pairs of speakers located in several differentrooms, or when listening to mono FM radio, to individual speakersplaced in different rooms. Use the Tuning Mode Button to select themono mode for FM radio.In addition to the audio signal, you will usually wish to connect an IRcontrol device to the AVR 247’s Multiroom IR Input so that listeners inthe remote room may turn the multiroom system on or off, select asource input, control the source device connected to that input andadjust the volume in the remote zone.NOTE: Only analog audio sources are available to the multiroomsystem.Step Eleven – Turn On the AVR 247Two steps are required the first time you turn on the AVR 247.1. Gently press the Master Power Switch until the word OFF is no longervisible. The Power Indicator above the two power switches shouldlight up in amber, indicating that the AVR is in Standby mode and isready to be turned on. See Figure 39. Normally, you may leave theMaster Power Switch in the ON position, even when the receiver isnot being used.Figure 39 – Power Switches2. There are several ways in which the AVR 247 may be turned on fromStandby mode.a) Press the Standby/On Switch on the front panel. See Figure 39.b) Press the Source Select Button on the front panel. See Figure 40.Figure 40 – Source Select Buttonc) Using the remote, press any one of these buttons: AVR, DVD/CD,TAPE/The Bridge, HDMI 1/2, VID1, VID2, VID3, VID4, XM, AM/FMor 6/8CH. See Figure 41.Figure 41 – AVR and Input SelectorsNOTE: Any time you press one of the Input Selectors on theremote (i.e., DVD/CD, TAPE/The Bridge, HDMI 1/HDMI 2, VID1,VID2, VID3 or VID4), the remote will switch modes so that it willonly transmit the codes programmed to operate that device. Inorder to control the receiver, press the AVR Button to return theremote to AVR mode.
