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 (+) 5 V, negative trigger (grounding
type), or cannot sustain (+) 12 V 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 R2-A75M/R2-A60F must be
connected to a switched power source (ignition)
in the vehicle. Be sure to use a 3 A fuse as close
as possible to this ignition tap. Using this
connection method, the R2-A75M/R2-A60F 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 3 A fuse
mentioned above, may be installed in-line on
the R2-A75M/R2-A60F turn-on lead. This switch
will then be used to turn on (and off) the
R2-A75M/R2-A60F. 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.

Auto Turn-on Switch
a) For the “DC” Input setting,
connecting the Remote Turn-On
Lead is not required due to the
“REMOTE SENSING” function of
this product.
b) However, the “REMOTE SENSING”
function may not work correctly
depending on the signal source
connected. In such a case,
connect the Remote Turn-On
Lead to an incoming power
supply cord (accessory power) in
the ACC position and switch to
the “REM” Input setting.
• The DC offset auto turn-on circuit was
designed to work with ONLY high level signals
(i.e., speaker level signals). These high level
signals usually come from the amplified
output of radios, head units, and amplifiers.
Because LO signal input (i.e., low level signals)
cannot turn on the amplifier, the REMOTE
trigger signal must be supplied and the REM
setting needs to be used for LO signal input.*
∗ For details on turning on the unit with the
ACC trigger signal, see the Remote Turn-On
Lead (
) section (page 5).
Input Level Switch
a) If input is via the head unit
pre-out line using an RCA
extension cable (sold separately),
set to “LO”.
b) If input is via the head unit
speaker line using a speaker-RCA
conversion cable (sold
separately), set to “HI”.
Subsonic Filter Adjustment Knob (R2-A75M
only)
The subsonic filter is for cutting ultra low
frequencies from the input signal before being
amplified. Frequencies lower than the specified
frequency are attenuated at 24 dB/octave.
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) (R2-A75M only)
Use this control to adjust the crossover
frequency between 50 Hz to 400 Hz.
Bass EQ Adjustment Knob (R2-A75M only)

your bass response.
Input Gain Adjustment Knob
Set the R2-A75M/R2-A60F 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.
Filter Mode Selector Switch
(CHANNEL-1/2) (R2-A60F 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.
At this setting, Crossover Frequency
Adjustment Knob ( ) provides

Input Channel Selector Switch (CHANNEL-3/4)
(R2-A60F 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.
Filter Mode Selector Switch
(CHANNEL-3/4) (R2-A60F only)
a) Set to the “OFF” position when the

About Connecting to the Speaker Input Level System
When connecting by using the Speaker-RCA Conversion Cable (
) (sold separately), switch the Input Level
Switch ( ) to “HI”.

• Do not mistake the Speaker Output Lead on the head unit side connected to this unit.
Front Speaker output (L)/(R) to CH1/CH2, Rear Speaker output (L)/(R) to CH3/CH4
• For the “Speaker Input Level System” setting, connecting the Remote Turn-On Lead is not required due to
the “REMOTE SENSING” function of this product. However, the “REMOTE SENSING” function may not work
depending on the signal source connected. In such a case, connect the Remote Turn-On Lead to an
incoming power supply cord (accessory power) in the ACC position.
Important Tips on Bridging an Amplifier
Low output will result if only one channel input is used. The Y-adapter is not required if a stereo/mono pair
line output is used to drive both inputs of the bridged amp.

Cautions on Power Supply Wires
Use the specified wire size according to the total fuse capacity of the amplifier to be installed and the wire
length.
For details on the wire size to be used, refer to the supplied “Cautions on Power Supply Wires Connection”
and the following connection example.
Connection example when installing an amplifier alone
• When the wire length from the amplifier to the vehicle’s battery is (A)
Wire size used for (A): 4 AWG/21 mm
2
(Max. length 8 m)
• External Fuse capacity: Make it equal to or larger than the fuse capacity of the amplifier
R2-A75M: equal to or larger than 80 A
R2-A60F: equal to or larger than 60 A
(A)

Vehicle’s chassis
Vehicle’s battery
Amplifier
Connection example when installing two amplifiers with a fuse capacity of 80 A
and one amplifier with 60 A
• When the wire length from each amplifier to the distribution block is 1 m
Wire size used for (B): 4 AWG/21 mm
2
• When the wire length from the distribution block to the vehicle’s battery is 5 m
Wire size used for (C): 1/0 AWG/53 mm
2
or 4 AWG/21 mm
