Manual Test; A/D Data Check - Yamaha RX-V367 Service Manual

RX-V367/HTR-3063

8. MANUAL TEST

The built-in noise generator of DSP outputs the test noise through the channels specified by using the sub-menu.
The noise frequency for subwoofer is 30 to 80 Hz. Other than that, the noise frequency is 500 to 2 kHz.
8-1. TEST ALL
Noise is output from all channels.

9. A/D DATA CHECK

This menu is used to display the A/D conversion value of the microprocessor which detects panel keys of this unit and
protection functions in using the sub-menu.
When K1/K2 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 main menu by turning the "VOLUME" knob of this unit.
Numeric values in the figure are given as reference only.
*
9-1. PS/DC
PS: Power supply voltage protection detection
Voltage detects: AC2, ±12A, S9, +7D, +5A, +5I, -VP
Normal value:
DC: Power amplifier DC (DC voltage) output is detected.
Normal value:
If PS or DC becomes out of the normal value range, the protection function works to turn off the power.
*
9-2. TH1/TH2
Temperature of the heatsink is detected.
Normal value:
* If TH1 or TH2 becomes out of the normal value range, the protection function works to turn off the power.
