ARC Audio X2 1200.6 Panduan Pemilik

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.

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
FUSE 30 AMP X 3
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.
The X2 1200.6 includes a High-Pass crossover on channels 3
and 4 and fully adjustable bandpass crossovers on channels
CH3/4
1 and 2, and 5 and 6.
