Input Section

This X2-Series amplifier is equipped with a balanced differential
input stage that is compatible with any analogue source
including Balanced and Unbalanced RCA, Common ground
speaker level output and Bridged Tied Load (BTL) outputs
common to many OEM head units. The RCA pigtails included
with these amplifiers are intended to be used with the speaker-
level outputs of a radio or amplifier. These pigtails include a
divider network molded into the RCA end that reduces the
voltage of the signal from the source. If you are integrating
into an OEM system with balanced or common ground line-
level signals you should not use these Pigtails. In this case it is
recommended that you use an appropriate RCA cable with one set of ends removed as inputs for the amplifier.

Gain / Sensitivity Controls

Because of the wide range of head unit output configurations
available, all ARC Audio amplifiers have an adjustable input
sensitivity or "Gain" control. The gain is not a volume or a power
limiting control like a throttle. It makes the amp more sensitive
to input from the source. With the gain up the amp will reach
full output at a lower volume setting on the deck and becomes
more sensitive to noise from the car's electrical system. Try to
run the gain at the lowest setting possible for you system.
There is no correct gain setting. As different size and shape
speakers require different amounts of power to reach the same
output, the gain settings need to be adjusted to compensate for these speaker efficiency differences. If you tried to set all
the gains at half way you would probably find the system didn't sound very good. Use good judgment and optimize each
channel carefully as you configure the system. You want to set the gains to maximize the output of the amplifier, while
producing minimal distortion for your given source unit and music selection.

Crossover Controls

A crossover is a circuit that limits what frequencies are
produced by the amplifier, and subsequently, the speaker(s)
connected to the amp. A tweeter can be destroyed by bass
information. Those frequencies need to be filtered for proper
operation. Likewise, a subwoofer will not sound natural if it
is playing midrange frequencies. A crossover removes these
sounds from the signal going to the speaker. As you might
guess, careful adjustment is required to ensure that all the
speakers are playing in the correct frequency range and that the
net frequency response of the total system is smooth with no
over- or under-lap.

Crossover Range and Function Controls

The X2 600.4 features an elaborate crossover system that can
operating in low-pass or high-pass on all pairs of channels, and
in a band-pass configuration on channels 3 and 4.
When the Band Pass switch is turned on and the crossover
function switch is set to LOW, both the HIGHPASS FREQ and
LOWPASS FREQ controls will affect channels 3 and 4.
The LP RANGE switch in the X1 position sets the range of the
LOWPASS Crossover at 50Hz to 500Hz. In the X10 position,
the LOWPASS Crossover range is 500 to 5kHz.
