8 Input Gain Adjustment Control
Set the KTP-445U input gain to the minimum position. Using
a dynamic
CD as a source, increase the head unit volume
until the output distorts. Then, reduce the volume
1 step (or
until the output is no longer distorted). Now, increase the
amplifier gain until the sound from the speakers become
distorted. Reduce the gain
slightly so the sound is no longer
distorted to achieve the optimum gain setting.
CONNECTION CHECKLIST (Fig. 7)
Please check your head unit for the conditions listed
below: (Fig. 7)
a.
The
head unit does not have a remote turn-on
or
power
antenna lead.
b.
The
head unit's power antenna lead is activated only when
the radio is on (turns off in the tape
or
CD Mode).
c.
The
head unit's power antenna lead is logic level output
(+)
5V, negative trigger (grounding type),
or
cannot sustain
(+) 12V when connected to other equipment in addition to
the vehicle's power antenna.
If any
of
the above conditions
exist, the remote turn-on lead of your KTP-445U must be
connected to a switched power source (ignition) in the
vehicle. Be sure to use a 3A fuse as close as possible
to
this ignition tap. Using this connection method, the KTP-
445U will turn on and stay on as long as the ignition switch
is on.
If this is objectionable, a SPST (Single Pole, Single Throw)
switch, in addition to the 3A fuse mentioned above, may be
installed in-line on the
KTP-445U turn-on lead. This switch will
then be used
to
turn on (and off) the KTP-445U. Therefore, the
switch should be mounted so that is accessible by the driver.
Make sure the switch is turned off when the vehicle is not
running. Otherwise, the amplifi
er
will remain on and drain the
battery.
