Crossover Frequency Adjustment Knob (LP FILTER) (S-A60M/S-A55V only) Use this control to adjust the crossover frequency between 50 Hz to 400 Hz. Bass EQ Adjustment Knob (S-A60M/S-A55V only) Add a 50 Hz bass boost up to +12 dB to tune your bass response. Crossover Mode Selector Switch (S-A32F 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 Frequency Adjustment Knob (S-A32F only) Use this control to adjust the crossover frequency between 50 Hz to 400 Hz. Input Channel Selector Switch (CH-3/4) (S-A55V 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. Crossover Frequency Adjustment Knob (HP FILTER) (S-A55V only) Use this control to adjust the crossover frequency between 50 Hz to 400 Hz. Input Channel Selector Switch (SUB) (S-A55V 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 S-A55V. 10-EN ALPINE S-A60M/S-A32F/S-A55V 68-35792Z59-A (EN/FR/ES) About Lights up Is off whe Indica Blue Red (blinking Red

Crossover Frequency Adjustment Knob
(LP FILTER) (S-A60M/S-A55V only)
Use this control to adjust the crossover
frequency between 50 Hz to 400 Hz.
Bass EQ Adjustment Knob (S-A60M/S-A55V
only)
Add a 50 Hz bass boost up to +12 dB to tune
your bass response.
Crossover Mode Selector Switch (S-A32F
only)

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 Frequency Adjustment Knob
(S-A32F only)
Use this control to adjust the crossover
frequency between 50 Hz to 400 Hz.
Input Channel Selector Switch (CH-3/4)
(S-A55V 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.
Crossover Frequency Adjustment Knob (HP
FILTER) (S-A55V only)
Use this control to adjust the crossover
frequency between 50 Hz to 400 Hz.
Input Channel Selector Switch (SUB) (S-A55V
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 S-A55V.
