PANASTEREO CX230 CINEMA MONITOR
SYSTEM ALIGNMENT
After installation it is necessary to adjust each of the input levels of the monitor to ensure correct
balance between each input and to calibrate the auditorium sound level meter. Alignment is best
performed at the same time as the sound processor B-Chain alignment to avoid duplication.
Equipment required: Pink Noise Card, Real Time Analyser (RTA)
ALIGNMENT OF NON-BIAMPED SYSTEMS
1. Insert a pink noise card into the appropriate slot in the sound processor.
2. Set the sound processor to Optical Stereo and set the volume to level "7" for a pink noise level
of 85db in the auditorium.
3. Select the pink noise generator to CENTER.
4. Turn off the Sub Bass amplifier.
5. Check the SPL reading on the RTA. It should be 85dB. If not, check the B-Chain alignment of
the sound processor.
6. Select the "SOURCE" switch to "AMPS", and select "CENTER".
7. Adjust the "AMPLIFIERS - CL" trimpot so that the CX230 sound level meter reads 85db.
8. Select the "SOURCE" switch to "PROC".
9. Adjust the "Processor - CL" trimpot so that the CX230 sound level meter reads 85db.
10. Turn off the Centre channel amplifier and turn on the Sub Bass amplifier.
11. Note the SPL reading on the RTA.
12. Select the "SOURCE" switch to "AMPS", and select "SUB BASS".
13. Adjust the "AMPLIFIERS - SW" trimpot so that the CX230 sound level meter reads the same
as the SPL reading on the RTA.
14. Select the "SOURCE" switch to "PROC".
15. Adjust the "Processor - SW" trimpot so that the CX230 sound level meter reads the same as
the SPL reading on the RTA.
16. Turn on the Centre Channel amplifier.
