Input Output Test
Items Required
• Oscillator
•Noise meter
• DI-1 (ATT switch: -40 dB)
• Dummy plug (x 2)
• Dummy resistances (8Ω x 1)
• Connection cables
• 1/4-inch stereo phone plug with 33Ω load resistors

Testing Method
Following the table below, input the indicated signal to each input jack,
and verify that a signal with the indicated value is output via the
corresponding output jack.
* For PHONES OUT Test, connect a 1/4-inch stereo phone plug with 33Ω load
resistors to the PHONES jack.
* Input a balanced signal to the CH1 BALANCED connector via DI-1. Set the
ATT switch on the DI-1 to -40 dB and input the signal indicated on the table to
the INPUT jack on the DI-1.
* Connect a 8Ω dummy resistance to the output terminals for the speaker instead
of the speaker.
* Amp output is BTL (bridge output). When connecting the measuring device,
take the another ground.
* When connecting a plug to the PHONES jack on this product, speaker’s sound
is not muted.
* Speaker produces a small sound in PHONES OUT Test, however this is a
normal operation.
