10. AUDIO LEVEL ADJUSTMENT (SENSITIVITY CONTROL)
The microphone sensitivity is variable within a range of 15 dB.
To change the factory-preset level, follow the procedures below.
Step 1. Holding the microphone body, rotate the microphone grip
counterclockwise to remove it.
Step 2. Switch on the power of the tuner and microphone.
Step 3. Adjust the audio level control using a small screwdriver.
The microphone sensitivity increases as the control is rotated
clockwise, and decrease as rotated counterclockwise.
(Maximum input level: 130 dB SPL for maximum sensitivity and
145 dB SPL for minimum sensitivity).
Step 4. Adjust the corresponding tuner's volume control so that its knob points to the 2 o'clock position. When
the tuner's AF PEAK indicator remains lit, readjust the microphone's audio level control to the position
that causes the indicator to flash when the tuner output level reaches its peak. The AF PEAK indicator
lights when the output level reaches the point of about 3 dB below the clipping level.
Note: The AF PEAK indicator operates in response to the volume control position. However, the AF
LEVEL indicator (on the WT-4800) indicates the level regardless of the volume control setting.
Step 5. Replace the microphone grip.
