4.21 MUTE function check ...... (21) MUTE
(1) Outline
The function of the Mute circuit of the signal output at the
MONITOR OUT or STEREO OUT terminal is checked.
Until this test item is executed, the input signals of the MIC/
LINE INPUT terminal are output from the MONITOR OUT or
STEREO OUT terminal as they are. Once this test is started,
the output signals from these terminals are muted. The I/O
connection condition of the DSP is the same as the initial state
described in 3.2.
(2) Execution method in the normal state
The following message appears on the LCD. When proper
muting function is confirmed, press [KNOB-8].
21:MUTE
CPU MUTE NG OK
When OK is selected, the following message appears on the
LCD. After confirming the proper muting function, press
[KNOB-8].
21:MUTE
ANA MUTE NG OK
When OK is selected, the following message appears on the
LCD. After confirming the Mute Off state, press [KNOB-8].
The screen returns to the execution select screen and "O" is
displayed in the check item space.
21:MUTE
MUTE OFFOFF NG OK
(3) Execution method in the faulty state
If the muting function does not work properly, press the [KNOB-
7]. The screen returns to the execution select screen and "X" is
displayed in the check item space.
(4) Item description and error message
None
(5) Check point when judged as NG
The devices that can be diagnosed by this check are as follows.
Circuit board Device name Function
DM CPU (IC101) CPU MUTE output

AN TR310-312 etc Muting circuit
4.22 FADER LEVEL adjustment ...... (22) FADER LEVEL
(1) Outline
The operation condition of the motor fader is stored in the
memory of the program in the main unit so that the fader operates
properly.
(2) Execution method in the normal state
In this mode, the nine faders move to almost the uppermost
position and the following message appears on the LCD.
22:FADER LEVEL
SET UPPER LEVEL (+6/0dB) ENTER
After setting faders 1 to 8 to "+6" position and the STEREO
fader to "0", press the [KNOB-8], and that position is saved in
the memory of the main unit. Then, the nine faders move down
to approximately the center position. The following message
appears on the LCD.
22:FADER LEVEL
SET CENTER LEVEL (-7.5/-20dB) ENTER
