3.15.1 Preparation
Connect the inspection circuit to the MONITOR/REMOTE terminal (JK304).
Check that the tolerance of the connected resistor is 1% or less, the rated power is 1/4 W or more and the tolerance of the DC
current voltage is 1% or less.

3.15.2 Output level
Input a 1 kHz, -10 dBu signal and check that the output voltage at pins 14 and 15 of JK304 is 4.8
±
1.0 dBu.
3.15.3 Mute and protection status
Input a 1 kHz, -10 dBu signal.
Check that the DC voltage at pins 10 and 11 of JK304 is +2
±
0.5V .
Turn on SW1 and check that the DC voltage at pin 11 of JK304 is 0.5 V or less and the voltage level at the output terminal of
the A channel is -30 dBu or lower.
Turn on SW2 and check that the DC voltage at pin 10 of JK304 is 0.5 V or less and the voltage level at the output terminal of
the B channels is -30 dBu or lower.
3.15.4 Model ID
Turn on SW3 and check that the DC output voltage at pin 3 of JK951 is within the range for “ID-V” specified in the table below.
