Basic OperationJBL SYNTHESIS SDP-45- 20 -1 HDMI InputsHDMI inputs 1 through 8 are hardwired to Source inputs 1 through 8 aslisted on the front panel from left to right. HDMI video is routed directly tothe two (2) outputs without any processing or transcoding. Audio may beextracted from the HDMI inputs if desired by pressing the HDMI buttonon the front panel for the source that is currently selected. These HDMIinputs are all v1.4 compatible and pass through all 3D formats. All HDMIinputs can extract and decode all current HD audio formats up to andincluding Dolby TrueHD and DTS-HD Master Audio2 Zone 2 Outputs (Unbalanced RCA)A pair of RCA jacks that provide a second stereo signal path completelyseparate from the main output with its own independently selected inputs3 TV Loop (Analog Inputs and Outputs)A conventional TV loop consisting of two pairs of RCA jacks; one stereopair of inputs and one stereo pair of outputs. A stereo down-mix for theselected source (or, in 2 Channel Bypass mode, the Left and Rightanalog inputs directly) appear at the TV OUTPUTS, unless the selectedsource is the TV INPUT itself in which case the TV OUTPUTS aremuted. The inputs can also be used as another pair of analog inputs, atunity gain.4 DVR Loop (Analog Inputs and Outputs)A second record loop which functions same as the TV Loop above.5 Unbalanced Analog InputsFour pairs of general purpose analog inputs labeled BLU-RAY,SAT/CBL, GAME and MEDIA.6 HDMI OutputsHDMI Outputs (1) and (2). Always connect the primary display to HDMI(1). HDMI video is switched to these outputs from the HDMI inputsabove. More detailed information on the use of both outputs is below insection USING DUAL HDMI OUTPUTS on pg - 22 -.7 S/PDIF Digital COAX InputsThe BLU-RAY, SAT/CBL, GAME, and MEDIA PLAYER front panelselectable sources are supplied with a COAX RCA jack digital audioinput. These four inputs will accept any standard S/PDIF source PCM (2channel), Dolby Digital and DTS formats. These input assignments canbe changed at any time.8 USB 2.0 Type A InputUsed as a digital audio and control input from computers and similarsources. This source does not have any video assigned. The last usedvideo source will remain active when selecting this input. To select avideo source first select the active video source and then select the 7.1or USB input. If no video is required then do not first select a videosource.9 RS232 9-Pin Serial (Female)Serial data port utilizing a DB9 female connector. For connection tosystem control systems such as Crestron, Savant, AMX and others.10 Power Cord InletUse with a standard IEC removable power cord (included).11 Ethernet 10BaseT (RJ45) PortFor interconnection to personal computers (and/or routers) to facilitateSDP-45 software updates; and also for control functions through systemcontrollers (Crestron, AMX, etc.). This acts an HTTP server.12 Toslink Optical Digital Inputs and OutputThe DVR, and TV front panel selectable sources are also supplied with astandard optical digital audio input. These three inputs will accept anystandard S/PDIF source PCM (2 channel), Dolby Digital and DTSformats. These input assignments can be changed at any time.The Toslink Digital output always sends a digital signal that is identical tothe MAIN Left and Right output. No down-mixing or bitstream passthrough is used.
