Introduction
The unit is carefully calibrated at the factory. The performance may change over time or due to environmental changes,
and the following recalibration procedures can be used to bring it back to its factory settings. If you do not feel comfortable
doing these calibrations, then we recommend they are done by an experienced audio service technician. This is especially true
for those units that need to be opened to gain access to voltage test points and calibration potentiometers.
CAUTION: Incorrect calibration or damage to the delicate adjustment potentiometers may lead to the unit
becoming inoperable.
Note: Although re-calibration will not invalidate the warranty, any damage caused during re-calibration may invalidate
the warranty.
Equipment required
1. Digital DC Voltmeter
2. 3.5 mm patch cable
3. Phillips screw driver
4. Small Insulated trimmer screwdriver
5. PC Computer with MIDI-OX installed
6. USB cable
Calibration Procedure
Follow all steps in the order in which they are presented.
IMPORTANT NOTE: Make sure the unit has been powered on for more than 30 minutes, and that it is in a place where the
temperature will not change drastically while performing the calibration.
