ELECTRICAL ADJUSTMENTS
Notes:
1. These adjustments are performed in the order that they are
described.
2. Adjustment and measurement are performed for each channel
unless otherwise specified.
3. Adjustment is made for the right channel first and then the left
channel.
4. The power voltage is supplied with 9 V.
Oscillation Frequency Adjustment
Setting:

–
Adjustment method:
• Perform this adjustment without signal.
1. Connect TP L (L-ch) and TP R (R-ch) to ground on the LED
board (to set the mute state), or use the test mode to set the mute
state (see page 7).
2. Connect a digital frequency counter to TP03 or TP04 for L-ch
and TP05 or TP06 for R-ch on the LED board.
3. Adjust L51 (L-ch) and L1 (R-ch) on the TX board so that the
reading on the digital frequency counter is each within 2.3 MHz
(L-ch) and 2.8 MHz (R-ch).

Adjustment method:
• Perform this adjustment without signal.
1. Connect TP L (L-ch) and TP R (R-ch) to ground on the LED
board (to set the mute state), or use the test mode to set the mute
state (see page 7).
2. Connect a digital voltmeter to TP03 or TP04 for L-ch and TP05
or TP06 for R-ch on the LED board.
3. Adjust RV51 (L-ch) and RV1 (R-ch) on the TX board so that
the reading on the digital voltmeter is 480 mV.
Specified value:
L-chRV51477.5 to 482.5 mV
R-chRV1477.5 to 482.5 mV
Caution:
