Output Level Difference
The gain differences when MONITOR OUT AL, AR, BL, and BR and CUE OUT L and R are measured at 1 kHz must be within
the following range.
3-5.
PHONES OUT AL, AR, BL, and BR
Conditions: Inspect according to 16. ANALOG OUT in the Test Program Specifications KES-92654.
Measure the SELECT INPUT CHANNEL side terminal and front pad bottom terminal.
