6-3. Modifi cation 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 in-
ternal speaker is exceeded. Therefore, use the KES-5.
