Select this test (T22) and press the [ENTER] button (or if the
test command is received), and tests
q and w are executed
automatically.
For test
e or thereafter, use the [ENTER] button to switch
Audio channels or switch ON/OFF of the MUTE or SRC-
BYPASS.
[Check item]
The unit automatically judges for q , w , t , y and u . Check
the result shown on the LCD.
In case of NG, the cause will be shown. Audibly check sine
wave for tests
e and r .

* Output to the STEREO OUT of the unit is changed
with the [ENTER] button. Output destination to the
unit is switched by
6 ch on the MLAN circuit board
side.
* SRC-BYPASS is OFF (SRC=ON) and Fs of the MLAN
circuit board (DICEII) is 96 KHz.
(B) Test r
SWP51-ch1&2 OUT " MLAN-ch1&2 IN
* SRC-BYPASS is OFF (SRC=ON) and Fs of the MLAN
circuit board (DICEII) is 96 KHz.
u GUID check: The unit asks GUID of the MLAN
circuit board (or mLAN16E2). The
MLAN circuit board (or mLAN16E2)
returns written GUID to the unit. The
unit shows lower 5 byte received on
the display.
[Test method]
Connect a speaker so that sounds from the [OUTPUT L/
MONO, R] or [DIGITAL OUT] jack can be heard. Connect
hubs (with power turned on for both) to the IEEE1394 ports 1
and 2.
