2.3 Indication upon Balancing
Pressing BAL knob (4) executes bridge check and cable length compensation, thus automatically
realizing both resistance balancing and capacitance balancing. While the bridge check and cable
length compensation functions are effective (ON), the following indications appear. If there is
bridge cable disconnection or short, the problematic location is indicated repeatedly on digital
monitor (3). The indication continues until the BAL knob is pressed for five seconds or longer or
the power of amplifier is turned off. Make repair following the indication. When bridge check is not
effective (OFF), the portions enclosed by broken line are omitted, executing auto-balancing. For
how to set these functions to ON or OFF, refer to page 3-8 How to Switch Special Function
Setting.
