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.
REAR SURROUND SPEAKER AND AMPLIFIER REQUIREMENTS
The rear wall surround speakers should be ideally of the same type as the side wall speakers to allow
the best match in sound quality between the side and rear wall speakers. The rear wall amplifier and
speaker system should have sufficient power handling capability to match that of either side wall
system. The number of rear wall speakers will be determined by the width of the auditorium – the
wider the room the more speakers will be needed. The spacing between each of the rear speakers
should be no greater than the spacing between each of the side wall speakers.
INSTALLATION IN A TWO LEVEL CINEMA
The Panastereo SP23 can be easily adapted to dual level cinemas. Such cinemas, which are usually
large older style cinemas, typically have an upstairs balcony and a downstairs stalls area beneath the
balcony. For such cinemas, rear wall surround speakers will be required both upstairs and
downstairs. In such cases the rear left output can be used to drive the upstairs speakers and the rear
right output can be used to drive the downstairs speakers. In the SP23-10 there are separate
equalisers for rear left and rear right channels so the upstairs and downstairs rear speaker systems
can be separately equalised for optimum results.
CONTROL & AUTOMATION CONSIDERATIONS
The automation connector on the SP23 is pin compatible with Panastereo CSP1200, Panastereo
CSP4200, Dolby CP65 and Dolby CP500 processors. When a standard pin for pin cable is used with
any of the above processors, the rear surround decoding will be turned on for any digital or magnetic
format and turned off for all other formats. For use with other processors, or if it is desired to alter
which formats turn the decoding on or off, it will be necessary to make a custom cable. In this case,
reference should be made to the automation pinout table in this manual.
