• AUDIO BUS
The AUDIO BUS setting is fi xed at “THRU” in this menu. In the
“THRU” setting, the A/D and D/A converters are internally con-
nected. Also the CHAN A/C and B/D PAN setting are set to left
and right respectively. Thus, the signals fed to CHAN A and C are
summed and output from the STEREO OUT L and the signal fed to
CHAN B and D are summed and output from the STEREO OUT R.
This mode is convenient when checking the input circuit.
• ATA BUS
The “OK” sign indicates that the ATA bus communication between the internal HD and the CPU is properly
made. If the “NG” sign appears, something must be wrong with the ATA bus communication.
• INPUT SEL
The “INPUT SEL” indicates the number corresponding to the INPUT A SELECT switch setting as follow.
GTR CLEAR: 2

MIC/LINE: 3
• FOOT SW
When an unlatched type foot switch is connected and it is pressed,
the “ON” indication will appear. If the foot switch is released or is
not connected, the “OFF” sign will appear.
• USB BUS
If the “USB BUS” section indicates the “OK” sign 3 ~ 5 seconds
after the “WAIT..” sign is displayed, the USB HOST function works
properly. If the “NG” sign is displayed, press the
[MENU/ENTER]
dial and then try to enter the Bus Check mode again by pressing the [MENU/ENTER] dial.
• ATAPI BUS
The “OK” sign indicates that the ATAPI bus communication between the CD-R/RW drive and the CPU is
properly made. If the “NG” sign appears, something must be wrong with the ATAPI bus communication.
