  • Page 8: Introduction

    Introduction The SDP-3 can be thought of as four units in one. At its heart is a reference-quality 8-channel music and film digital audio computer capable of creating or recreating a limitless amount of listening environ- ments. This digital audio computer is mated to an 8-channel, 24-bit Digital-to-Analog converter that rivals the most exotic and costly stand- alone devices.

    DTS Digital Surround input signals. Any DTS-capable software and/or source components should be labeled with a logo, similar to the one on the SDP-3 front panel. Downmix describes the process of creating a two-channel output from a multichannel (>2) signal.

  • Page 10: Controls And Indicators

    Effect An effect is a configuration that determines how the SDP-3 will process an input signal. The SDP-3 contains 24 effects: Panorama, Jazz, Classical, Football, Cathedral, Party, 2-Channel, Music Surround, Rock/Pop, Logic 7, Television, Pro Logic, THX Cinema, Mono Enhance, 5.1 2-Channel, 5.1 Music, 5.1 Logic 7, 5.1 Dolby, 5.1 Dolby/THX, DTS...

  • Page 15: Connection

    The SDP-3 has a master power switch on the rear panel above the IEC standard AC power receptacle. This switch may be left ON continuously when the unit is in regular use. When the SDP-3 will not be used for an extended period of time, or whenever you are connecting or disconnect- ing any cables to the unit, this switch should be turned OFF.

  • Page 16: Wiring Considerations

    (Unplug any components that don’t have power switches.) The SDP-3 is designed to function as the control center of the system, selecting inputs and controlling the volume of all speakers in the system. The following diagram shows a system with a tape deck, an AM/FM tuner, a CD player with a coaxial digital audio output, a satellite receiver with an optical digital output, a DVD player and a VHS VCR.

  • Page 17: Connecting The Sdp-3 As A Preamp

    OUTPUT SUBWOOFER EQ/Amplifiers and Speakers Input sources should be connected directly to the SDP-3 inputs. Connect the Left, Center, Right, Subwoofer, Left Side and Right Side outputs to the inputs of the JBL Synthesis SDEC Digital Equalizer. Connect the Rear Left and Rear Right outputs, if used, directly to the appropriate amplifier inputs.

  • Page 19: Ready" Laser Disc And Ld/Dvd Players

    "AC-3 ready" laser disc and LD/DVD players output Dolby Digital (AC-3) data from laser discs on a separate RCA jack in Radio Frequency (RF) form. To maintain the exceptional performance of the SDP-3, an outboard demodulator is required to turn this RF signal back into a digital bitstream.

  • Page 22: Display Adjustment

    Since the on-screen display is capable of showing the full menu of options available at any point, calibration of the system is faster and easier if the SDP-3 video output is connected to a video monitor.
  • Page 23 Adjusting the position allows you to move the SDP-3 display items to a location where they will not interfere with any other video overlays or signals your system may generate.

  • Page 24: Input Configuration

    IN, this control is automatically set to OFF. The SDP-3 has eight inputs, each of which can be associated with any of the eight video and eight digital audio inputs. Selecting Input Configu- ration from the Setup menu displays a sub-menu which lists these inputs and allows you to select them individually for adjustment.

  • Page 29: Audio In

    This option in the INPUT CONFIG menu determines which audio input connector on the SDP-3 rear panel will be used for the MAIN zone. Using the digital inputs will usually yield better performance, and these should be used whenever a source component has a digital audio output.

  • Page 33 SMALL routes the low frequency information to the subwoofer output. Selecting NONE mutes the rear outputs and directs all surround information to the side outputs. When used with JBL Synthesis systems using side and rear speakers, this setting should be on SMALL at 80Hz.

    5.1-channel THX listening. This setting is not recommended for 7.1-channel configuration. This configuration is not adjustable. When SDP-3 input and output levels are set properly, the entire system will be calibrated to play films at the level intended by the director.

  • Page 35: Note On External Noise Calibration • Subwoofer

    When using the external noise calibration, the SDP-3 will load the factory default effect for the format of the incoming signal. In other words, if a PCM signal is coming into the SDP-3 when external noise is engaged, the SDP-3 will load the PRO LOGIC effect with the factory preset settings.
  • Page 36 Pressing SELECT routes low frequency calibration noise to the subwoofer output of the SDP-3. A two-line display indicates the LIM- ITER LEVEL setting in dB on the top line with a bar at the bottom to indicate relative noise level.

  • Page 37: Zone 2 Power On Volume

    This control in the Output Levels menu allows you to select the volume at which the SDP-3 will power on. You can choose from a range of -80 to +6dB, or elect to have the system power on at the last level used (LAST LVL).
  • Page 38 SDEC Digital EQ. A/V Sync Delay compensates for the delay that occurs when a video processor, such as a scan rate converter, is used with the SDP-3. Most of these processors alter the original audio/video timing relationship by adding delay to the video signal as it is processed.

    This menu item assigns the status for the remote trigger voltage that appears on pin 5 of the DIN jack on the SDP-3 rear panel. +5VDC is provided for controlling ancillary equipment or functions. This signal can be enabled or disabled for the selected effect.

  • Page 44: Pcm Effects And Parameters

    The location of the front speakers and the listening position are crucial to Panorama’s effectiveness and for best results your system and the SDP-3 together should be set up and calibrated according to the procedure in Chapter 2. The strength of the Panorama effect drops off as you move away from the prime listening position, especially to the sides.

  • Page 45: Classical

    The Classical Effect generates the appropriate early reflections for stereo simulation of many different halls, and sends the reflections to all channels in addition to the direct signal in the main speaker. This Effect is not appropriate for highly percussive music.
