• For details on how to connect, see “Cautions

on wire lead connections” (page 6).

Ground Lead (sold separately)

Connect this lead securely to a clean, bare metal spot on the vehicle’s chassis. Verify this point to be a true ground by checking for continuity between that point and the negative (–) terminal of the vehicle’s battery. Ground all your audio components to the same point on the chassis to prevent ground loops while keeping wire length as short as possible.

• For details on the wires size to be used, refer to

the supplied “Cautions on Power Supply Wires Connection” and “Cautions on Power Supply Wires” (page 20), and then use the wire of the specified size.

Remote Turn-On Lead (sold separately)

Connect this lead to the remote turn-on (positive trigger, (+) 12 V only) lead of your head unit. If a remote turn-on lead is not available, see “CONNECTION CHECK LIST” section on page 7 for alternative method.

• When connecting the speaker output leads of

the head unit to this unit with a Speaker-RCA Conversion cable (sold separately), you do not need to connect the remote turn-on lead, owing to the “REMOTE SENSING” function of this unit. 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.

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

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)

Add a 50 Hz bass boost up to +12 dB to tune 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 adjustment between 50 Hz to 400 Hz. 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.

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.

c) Set to the “LP” position when the

amplifier is used to drive a subwoofer. At this setting, Crossover Frequency Adjustment Knob ( ) provides adjustment between 50 Hz to 400 Hz. The frequencies above the crossover point will be attenuated at 12 dB/octave.

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

b) Set to the “HP” position when the

d) Set to “BP” if the amplifier is used to

drive a midbass or midrange speaker. Frequencies lower than the specified frequency set by Crossover Frequency Adjustment Knob ( ), and higher than the frequency specified set by Crossover Frequency Adjustment Knob ( ), are attenuated at 12 dB/ octave.

Crossover Frequency Adjustment Knob (HP/ LP/BP-L FREQ.) (R2-A60F only)

Use this control to adjust the crossover frequency between 50 Hz to 400 Hz.

NOTE:

• When the Crossover Mode Selector Switch (

is set to [BP], adjust the Crossover Frequency Adjustment Knob ( ) and ( ).

Crossover Frequency Adjustment Knob (BP-H FREQ.) (R2-A60F only)
