Page 6: System Alignment
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. - Page 7 PANASTEREO CX230 CINEMA MONITOR 17. Select the pink noise generator to LEFT. 18. Check the SPL reading on the RTA. It should be 85dB. If not, check the B-Chain alignment of the sound processor. 19. Select the “SOURCE” switch to “AMPS”, and select “LEFT”.
