User manual JBL ONST400ID

[. . . ] Observe the maximum ambient operating temperature listed in the product specification. Slots and opening on the case are provided for ventilation; to ensure reliable operation and prevent it from overheating, these openings must not be blocked or covered. Never attach audio power amplifier outputs directly to any of the unit's connectors. To prevent shock or fire hazard, do not expose the unit to rain or moisture, or operate it where it will be exposed to water. [. . . ] When the disc begins to play, the SDP-RFD recognizes that it is not AC3 encoded, and automatically routes the signal to the SDP-3. The SDP3 recognizes the DTS signal and automatically loads the DTS LOGIC 7 effect*. The FX and buttons are used to audition the other available DTS effects and DTS MUSIC is selected. At some point, the skip button on the laser disc player is pressed several times to advance to a different track . This causes the laser disc player to temporarily replace the DTS output signal with a PCM signal while it searches for the selected track. This change is recognized by the SDP-3, which automatically loads the Logic 7 effect (because in this example, AUTOMATIC is selected as the setting of FX FORMAT and Logic 7 is selected as the PCM FX in the INPUT CONFIG menu). When playback is resumed, the SDP-3 automatically reselects the DTS MUSIC effect. * To go back to the effect selected as a default, simply press the input button. * As the SDP-3 is in AUTOMATIC mode, there may be a brief burst of noise before normal playback begins. 18 SDP-3 Digital Surround Processor/Controller System Configuration PCM Only NOTE: PCM ONLY is automatically selected for an input whenever ANALOG is selected as the AUDIO IN setting, as AC-3 and DTS effects are incompatible with analog inputs. If PCM ONLY is selected as the FX FORMAT for a given input, only PCM effects in the SDP-3 can be used. When the SDP-3 receives a signal which is not PCM encoded, it will mute and display "NO PCM AUDIO. " In the previous example, if PCM ONLY had been selected, rather than AUTOMATIC, the SDP-3 would have muted and displayed "NO PCM AUDIO" when the AC-3 movie and the DTS music disc were being played. AC-3 Only NOTE: As AC-3 is a digital format, you must have a digital input selected for AUDIO IN in the INPUT CONFIG menu. When AC-3 ONLY is selected as the FX FORMAT, only AC-3 effects can be used on that input. Any other type of signal received on that input will cause the SDP-3 to mute and display "NO AC-3 AUDIO. " The FX and buttons will select only AC-3 effects. 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. This prevents feedback from occurring with devices that have both an input and output attached to the SDP-3 (Tape deck, VCR, etc. ). Record/Zone 2 Controls Record/Zone 2 functions can be accessed from the SDP-3 front panel or the remote control. In either case, press and hold Record/Zone 2 while pressing one of the following buttons. ON Turns on the Zone 2 outputs, lights the red Record/Zone 2 front panel 21 System Configuration JBL Synthesis LED and redirects the current main zone input to the Record/Zone 2 outputs. OFF Turns off the Zone 2 outputs, and the associated front panel LEDs. OSD (ON) Displays a STATUS menu for the current input. Press Done to exit. VOL and Displays, then adjusts the current Zone 2 volume level. [. . . ] There are commercially available antenna lead isolators which may provide additional insulation from electrical surges. Also try disconnecting all video connections to the SDP-3 to see if the video equipment is causing the problem. The SDP-3 does generate minimal amounts of RF energy and is in compliance with FCC rules and CE standards. If some interfering noise is noted, move AM loop and FM "T" type antennas away from the SDP-3 and reorient them as necessary. [. . . ]
