Calibration Procedure
This procedure will calibrate the TCR’s analog signal path to ensure that proper signal levels are
recorded and reproduced. Calibration compensates for normal gain variations for each channel that
result from the manufacturing process. Calibration is performed in two steps:
•
Adjustment of analog output gain to a known value using an internally generated reference
•
Adjustment of analog input gain, using an externally applied reference.
The input gain may be adjusted ±9.99% from nominal. The TCR is calibrated before leaving the
factory.
Note To ensure the accuracy of the TCR calibration, the audio converter
circuits inside the machine must warm up for at least 15 minutes
before calibration. It is also recommended that the TCR be turned
ON and allowed to warm up before each use, to ensure that you are
working with the calibrated settings.
