8-3. Modification to increase the audio output of
the control head
The speaker output can be increased to 13W by moving
jumper resistor (0 ohm) R74 to $R73 on the KCH-14 display
unit (X54-349 A/3). In this case, the KCH-14 internal speaker
cannot be used because the maximum input (3W) of the
internal speaker is exceeded. Therefore, use the KES-5 or
KES-6.
Note :
Even if the KRK-6DH is modified in this way, the audio
output of head 2 cannot be increased.

(Only when the PA or SP switch is on.)
4. If you use the transceiver shorted with pins 3 and 6, the
internal speaker is available (when the KCH-14 is used).
The KCH-15 does not contain a speaker.
