A/D DATA CHECKThis menu is used to display the A/D conversion value of the microprocessor which detects panel keys of this unit andprotection functions by using the sub-menu.When K0/K1 menu is selected, keys become non-operable due to detection of the values of all keys.However, it is possible to advance to the next sub-menu by turning the VOLUME of this unit. When using this function,note that turning the VOLUME more than 1 click would cause the volume value to change.Signal processing is maintained in the status before execution.* The figures in the diagram are given as reference only.PD/PVPD: PRD (Power amplifier DC protection detection)The output of power amplifier DC (DC voltage) is detected.Normal value: 35 to 81 (Reference voltage: 3.3 V=255)PV: PRV (Voltage protection detection)Voltage detects: ACL, AC2, 10V, S9, +12, -12, +5V and VPNormal value: 84 to 153 (Reference voltage: 3.3 V=255)* If PRD and PRV becomes out of the normal value range, the protection function works to turn off the power.TH/PLTH: THM (Thermo protection detection)The temperature of the heat sink is detected.Normal value: 0 to 124 (Reference voltage: 3.3 V=255)* If THM becomes out of the normal value range, the protection function works to turn off the power.PL: PLDET (Power limiter detection)The output voltage of power amplifier is detected.PI/DEPI: PRI (Current protection detection)The current of the power amplifier is detected.Normal value: 0 to 100 (Reference voltage: 3.3 V=255)DE: PDET (Sub-trans power detection)Normal value: 209 to 255 (Reference voltage: 3.3 V=255)* If PRI and PDET becomes out of the normal value range, the protection function works to turn off the power.
