HVR-M25J/M25U/M25N/M25E/M25P/M25C
9. E-E AUTO Check
Mode E-E
Signal Audio: 1 kHz, –4 dBs signal
AUDIO IN terminal (CH-1, 2)
Measurement Point AUDIO OUT terminal (CH-1, 2)
Measuring instrument Audio level meter
Specified Value –8 to –4 dBs (NTSC)
–10 to –6 dBs (PAL)
Note: 0 dBs = 0.775 Vrms
Switch setting
1) AUDIO MODE (AUDIO SET menu) ......................... FS32K
2) AUDIO INPUT switch (AUTO/MANU) ..................... AUTO
3) AUDIO INPUT LEVEL switch ....................................... –10
Checking method:
1) Enter 1 kHz, –4 dBs signal to the AUDIO IN terminal (CH-1,
2).
2) Check that the output of AUDIO OUT terminal (CH-1, 2) sat-
isfies the specified value.
10. E-E AUTO Maximum Input Check
Mode E-E
Signal Audio: 1 kHz, +18 dBs signal (NTSC)
AUDIO IN terminal (CH-1, 2)
Measurement Point AUDIO OUT terminal (CH-1, 2)
Measuring instrument Oscilloscope
Specified Value No clip is found in the output waveform.
Note: 0 dBs = 0.775 Vrms
Switch setting
1) AUDIO MODE (AUDIO SET menu) ......................... FS32K
2) AUDIO INPUT switch (AUTO/MANU) ..................... AUTO
3) AUDIO INPUT LEVEL switch ....................................... –10
Checking method:
1) Enter 1 kHz, +18 dBs signal to the AUDIO IN terminal (CH-
1).
2) Measure the output of AUDIO OUT terminal (CH-1), and check
that no clip is found in the output waveform
3) For the CH-2, make a checking in the same manner.
