Test 21
Function:
MIC L check
Description:
Check output sound with MIC L input. Check that there is no
abnormal sounds or noise.
The [MASTER VOLUME] can be set to any level.
Set the [INPUT VOLUME] to the maximum level.
Set the [LINE IN/MIC TRIM] volume to the maximum level
Connect a level meter (JIS-C curve) to the L/L+R of [AUX
OUT/LOOP SEND] terminal. (Load should be 10 k
Ω
.)
Input signal of -45 dBu (1 kHz sine wave) from an oscillator
to the L/L+R of [LINE IN/MIC] terminal and measure at
output terminals.
• AUX OUT/LOOP SEND L/L+R: +13.0±2 dBu
¡
Amount of TRIM volume decay:
Change the [LINE IN/MIC TRIM] volume to the minimum
level with the other setups remained as above. (Leave the
[INPUT VOLUME] at the maximum position.)
Measure output terminals.
• AUX OUT/LOOP SEND L/L+R: -34.0±2 dBu
¡
Amount of volume decay:
Change the [INPUT VOLUME] to the minimum level with
the other setups remained as above.
(Leave the [LINE IN/MIC TRIM] volume at the minimum
level.)
Measure output terminals.
• AUX OUT/LOOP SEND L/L+R: -70.0 dBu or less
Check also if connection and disconnection of MIC is
detected by inserting and removing MIC.
