CONNECTION CHECK LIST
Please check your head unit for the conditions listed below:
Remote Turn-On Lead
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 X-A90M/X-A70F/X-A90V 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 X-A90M/X-A70F/X-A90V 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 X-A90M/X-A70F/X-A90V turn-on lead. This switch will then be used to turn on (and off) the X-A90M/X-A70F/X-A90V. 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 amplifier will remain on and drain the battery.

Before switching each Selector Switch, turn off the power and insert a small screwdriver, etc.,
perpendicularly to the Switch.
Subsonic Filter (X-A90M/X-A90V only)
The subsonic filter for cutting ultra low frequencies from the input signal before being amplified. This is desirable for several reasons:
– To protect speakers too small or not capable
of reproducing ultra low frequencies.
– To minimize power wasted from reproducing
inaudible sound.
– To protect subwoofers in vented enclosures
from over excursion below the tuning frequency.
Crossover Frequency Adjustment Knob
(LP FILTER) (X-A90M/X-A90V only)
Use this control to adjust the crossover frequency between 50 to 400 Hz.
Bass EQ Adjustment Knob (X-A90M/X-A90V
only)
Add a 50 Hz bass boost up to +12 dB to tune your bass response.
9-EN
Page 12
Input Gain Adjustment Control
Set the X-A90M/X-A70F/X-A90V 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 becomes distorted. Reduce the gain slightly so the sound is no longer distorted to achieve the optimum gain setting.
Crossover Mode Selector Switch (X-A70F
only)
a) Set to the “OFF” position when the
amplifier will be used for driving full range speakers or when using an external electronic crossover. The full frequency bandwidth will be output to the speakers with no high or low frequency attenuation.
b) Set to the “HP” position when the
amplifier is used to drive a tweeter/ midrange system. The frequencies below the crossover point will be attenuated at 12 dB/octave.
NOTE:
In this case the maximum Bass EQ
boost level is reduced.
c) Set to the “LP” position when the
amplifier is used to drive a subwoofer. The frequencies above the crossover point will be attenuated at 12 dB/octave.
Crossover Mode Selector Switch (X-A90V
only)
a) Set to the “OFF” position when the
amplifier will be used for driving full range speakers or when using an external electronic crossover. The full frequency bandwidth will be output to the speakers with no high or low frequency attenuation.
b) Set to the “ON” position when the
amplifier is used to drive a tweeter/ midrange system. The frequencies below the crossover point will be attenuated at 12 dB/octave.
NOTE:
In this case the maximum Bass EQ
boost level is reduced.
Input Channel Selector Switch (SUBWOOFER)
(X-A90V only)
a) When this switch is placed in the
“1+2+3+4” position, all the signals are mixed and come out from the subwoofer. This setting provides signal to the subwoofer channel when only 4 channel input is available.
b) Setting this switch to “SUB” will
send the signal at the inputs of SUB to subwoofer of the X-A90V.
Crossover Frequency Adjustment Knob
(X-A70F/X-A90V only)
Use this control to adjust the crossover frequency between 50 and 400 Hz.
Input Channel Selector Switch (CHANNEL-3/4)
(X-A70F/X-A90V only)
a) This switch setting is for selecting
either 2-channel or 4-channel input mode. When set to “1/2”, signal will be copied from CH-1/2 and sent to CH-3/4, eliminating the need for Y-adapters.
b) Setting this switch to “3/4” will keep
both inputs, CH-1/2 and CH-3/4 independent. A 4-channel source is required for this mode.
