Page 3: System Features
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.
Page 4: 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.
Page 5: 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.
Page 6: Connecting The Inputs To The Sp23
Connect the ground terminal of each processor output to the “-“ terminal of each corresponding SP23 input. Connect the cable shield to the “E” terminal of each SP23 input only. Do not connect the shields at the sound processor. SOUND PROCESSOR WITH BALANCED OUTPUTS (PANASTEREO) Disconnect the left surround and right surround connections at the sound processor outputs.
Page 7: Connecting The Sp23 Outputs
Connect the “-“ terminal of each SP23 output to the “-“ terminal of each corresponding amplifier input. Connect the cable shield to the “E” terminal of each SP23 input only. Do not connect the shields at the amplifier. SP23 Rear Panel...
