PANASTEREO SP23 – Operation. PANASTEREO SP23 DIGITAL SURROUND PROCESSOR OVERVIEW The Panastereo SP23 Surround Processor decodes 6.1 channel sound from existing digital 5.1 installations. The SP23 works with any brand of 5.1 digital sound processor is inserted between the left and right surround outputs of the sound processor and the surround amplifiers. The SP23 provides a decoded rear surround channel which can be fed to rear wall surround speakers via a rear surround amplifier.
PANASTEREO SP23 – Operation. SP23 OPERATION The SP23 does not require any operator intervention for normal operation. The unit is automatically controlled by the cinema processor. When a digital format is selected on the cinema processor the SP23 will switch to EX decode mode and the red DECODE-ON indicator will be illuminated. In Digital mode the left and right surround channel information is decoded into three channels, left, right and rear surround.
PANASTEREO SP23 – Installation. SP23 INSTALLATION RACK MOUNTING THE SP23 The SP23 can be mounted anywhere in the sound rack, although it is preferable from a wiring point of view to mount the unit between the sound processor and the amplifiers. Provision should be made for ventilation above the SP23, so avoid mounting the unit directly beneath other equipment that will prevent air circulation at the top of the SP23 chassis.
PANASTEREO SP23 – Installation. CONNECTING THE INPUTS TO THE SP23. SOUND PROCESSOR WITH UNBALANCED OUTPUTS (DOLBY, SMART, ULTRA STEREO) Disconnect the left surround and right surround connections at the sound processor outputs. Use two-core shielded audio cable to connect the left and right surround outputs from the sound processor to the left and right inputs of the SP23. Connect the “+” terminal from each sound processor output to the “+” terminal of each corresponding SP23 input.
PANASTEREO SP23 – Installation. CONNECTING THE SP23 OUTPUTS. AMPLIFIERS WITH UNBALANCED INPUTS Use two-core shielded audio cable to connect the left, right and rear surround outputs from the SP23 to the inputs of the amplifiers. Connect the “+” terminal from each SP23 output to the “+” terminal of each corresponding amplifier input. Connect the ground terminal of each SP23 output to the “-“ terminal of each corresponding amplifier input.
PANASTEREO SP23 – Installation. SETTING THE EQUALISER MODE JUMPERS The SP23 has three EQUALISER MODE jumpers on the CM126 Power Supply/Control Card. The jumpers are marked LK1 – 3 The jumpers are factory set to match the equaliser configuration as shipped from the factory. LK1 – Selects the input for the third equaliser slot (the upper middle slot).
