User manual PANASTEREO CX230EX

[. . . ] Press the same button a second time to monitor the high frequency output only. Press the same button a third time to monitor just the low frequency output. Repeatedly pressing the same button will cycle through the above three options. MONITORING A MIX When the MIX button is pressed, the monitor output will be a blend of the front three channels (left, centre and right). In MIX mode a compressor is automatically inserted to reduce the difference in volume between very loud and very soft signals. [. . . ] The red bar at the right of the bar graph will disappear to indicate normal meter mode. 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. Set the sound processor to Optical Stereo and set the volume to level "7" for a pink noise level of 85db in the auditorium. Select the "SOURCE" switch to "AMPS", and select "CENTER". Adjust the "AMPLIFIERS - CL" trimpot so that the CX230 sound level meter reads 85db. 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. Select the "SOURCE" switch to "AMPS", and select "SUB BASS". Adjust the "AMPLIFIERS - SW" trimpot so that the CX230 sound level meter reads the same as the SPL reading on the RTA. Adjust the "Processor - SW" trimpot so that the CX230 sound level meter reads the same as the SPL reading on the RTA. Turn on the Centre Channel amplifier. PANASTEREO CX230 CINEMA MONITOR 17. Select the "SOURCE" switch to "AMPS", and select "LEFT". Adjust the "AMPLIFIERS - LL" trimpot so that the CX230 sound level meter reads 85db. Adjust the "Processor - LL" trimpot on the monitor so that the CX230 sound level meter reads 85db. 23. Select the "SOURCE" switch to "AMPS", and select "RIGHT". Adjust the "AMPLIFIERS - RL" trimpot so that the CX230 sound level meter reads 85db. Adjust the "Processor - RL" trimpot so that the CX230 sound level meter reads 85db. 29. Select the "SOURCE" switch to "AMPS", and select "LEFT SURROUND". Adjust the "AMPLIFIERS - LS" trimpot so that the CX230 sound level meter reads 85db. Adjust the "Processor - LS" trimpot so that the CX230 sound level meter reads 85db. PANASTEREO CX230 CINEMA MONITOR 35. [. . . ] The data format is fixed and is in the following format: One start bit, eight data bits, one stop bit, no parity, 9600 baud. Command String Format "Input select" and "volume set" commands are constructed using a seven character ASCII string. Commands start with a colon followed by a four character command terminated with a carriage return, and a line feed character which are also valid if they occur in reverse order. (This is to allow compatibility with languages that do not provide easy control of the order of these characters). [. . . ]
