[. . . ] Installation/ Technical Manual SDP-3 Digital Surround Processor/Controller Important Safety Instructions Save these instructions for later use. Follow all instructions and warnings marked on the unit. Always use with the correct line voltage. Refer to the manufacturer's operating instructions for power requirements. [. . . ] Note that selecting ANALOG will automatically select PCM ONLY as the FX FORMAT as the AC-3 and DTS effects are only compatible with digital inputs. COAX 1-5 and OPTICAL 1-3 (Digital Audio Inputs) When one of these eight digital inputs is selected, the SDP-3 will use it to derive the signal for the MAIN OUTPUTS. Note that all eight digital inputs can be used for various SDP-3 inputs. This is particularly useful when using a source component such as a VCR, laser disc or DVD player to drive multiple SDP-3 inputs. NOTE: The Expansion Port input cannot be assigned as the default for any input. Video In NOTE: S-Video input signals will be output on both the composite and SVideo jacks. However, if you are only connecting to the monitor via the SVideo output, composite video input sources will not be displayed. The inputs labeled VCR, DVD, V-DISC, TV, AUX, CD, TUNER and TAPE have corresponding video inputs. For maximum configuration flexibility, each of these video inputs can be assigned to a different input, or to multiple inputs. If the assigned video input has both S-Video and composite jacks, the S-video signal takes priority whenever a cable is plugged into the appropriate S-video connector. 20 SDP-3 Digital Surround Processor/Controller System Configuration Record/Zone 2 The SDP-3 is designed to be the control center of any system. As such, there are separate outputs for easy integration of external recording devices as well as an additional "zone" in multi-room installations. The Record and Zone 2 outputs on the SDP-3 are wired in parallel so that the input selection will always be the same for both. For example, if the CD input is selected for Record, the CD input is also output to Zone 2. The primary difference between the Record and Zone 2 outputs is that Zone 2 has its own volume control, while the Record output level is fixed. NOTE: When listening to DTS material from a source component, DTS digital data may also be sent out of the analog outputs. DTS data, which sounds like loud white noise, may cause damage to a system. As protection against feedback, the TAPE and VCR inputs are normally blocked from being used as sources for the Record and Zone 2 outputs. This default condition can be changed in the Input Configuration menu as follows. Use and to select REC/ZONE 2, then press SELECT. The and buttons will select ANALOG, DIGITAL, or BLOCKED as the state of the Zone 2 output. ANALOG allows maximum flexibility from digital sources by utilizing both the digital and analog outputs of a digital source component (provided both are connected). The SDP-3 processes the digital input signal for the main zone, and simultaneously routes the analog input signal to the Record and Zone 2 outputs. Since no D/A converters are necessary for the analog input signal, the functionality in the Main zone is not compromised. DIGITAL routes the digital signal, assigned to the input, to the SDP-3's 24-bit Digital to Analog (D/A) converters. After conversion, the signal is sent to the Record and Zone 2 outputs. As this setup bypasses the D/A converters in the source component, and utilizes the 24-bit D/A converters in the SDP-3, sound quality can be dramatically improved when recording or listening in Zone 2. Note, however, that this setup automatically loads the appropriate 2-Channel effect in the main zone. NOTE: Removing the block from any input which has both an input and output attached to the SDP-3 may cause damaging feedback. BLOCKED simply blocks the input from being sent to the Record and Zone 2 outputs. [. . . ] If this happens, contact JBL Synthesis Customer Service. If you find that your custom settings are routinely being corrupted, the lithium battery in the SDP-3 may need replacing. This part is not fieldreplaceable -- contact JBL Synthesis Customer Service. If the unit is still behaving erratically, perform the Restore Defaults procedure described on the following page. [. . . ]
