3. Audio test
Perform the through-playback and sine wave output.
• Contents of the submenu

ADA SP: AD/DA-through-SP mode
ADA LP: AD/DA-through-LP mode
DSP SP: DSP-through-SP mode
DSP LP: DSP-through-LP mode
1 kHz SIN: 1 kHz sine wave output mode

• Select the microphone sensitivity with the HOLD switch.

ON: High sensitivity

OFF: Low sensitivity

• The VOR detection operation can be checked by the LED.

Sound: The red LED is turned on. No sound: The red LED is

turned off.

• MUTE can be set to “ON” or “OFF” with the ERASE key.
• The sound volume can be adjusted with the VOLUME+ key or

VOLUME- key during the audio test except the MUTE mode.

• The microphone sensitivity, sound volume and MUTE (on/off)

are displayed on the bottom of the LCD.

11. USB test
• When the menu starts the USB self-check, either presence or

absence of the Vbus is judged.
(Vbus is present: “VBUS: ON”, Vbus is absent: “VBUS: OFF”)

• The USB driver always works regardless of presence or absence

of the USB signal only when Vbus is available during the USB
test. At this time, turning on HOLD causes the set to move to the
suspend state. Turning off the Vbus causes the set to return to the
test menu.
