Coustic 160SE - Manual (Page 2)

Welcome
… to the Coustic world of power and clarity. The new 160SE amplifier delivers the cleanest music
you’ve ever heard at any power level in the 12-volt environment. Besides the sleek contoured
design, the 160SE amplifier has all the latest and most sophisticated audio features. This manual
offers you a guided tour of all these exciting features. For the best sonic reproduction, please fol-
low the installation suggestions and recommendations as closely as possible. The time you
spend will prove to be worthwhile when you sit back and enjoy the high fidelity music!
To further explore the potential of your Coustic amplifier, we recommend you match it with our
full-feature high performance AM/FM CD/cassette source units, dynamic full-range speakers or
subwoofers, state-of-the-art equalizers and electronic crossovers.
Whatever you need for your ultimate car audio system, look to Coustic - we have the fullest
range of car audio components to meet the most critical demands.
That’s because …….COUSTIC ROCKS!

FEATURES
MULTI-FUNCTION CIRCUIT DESIGN
This amplifier has built-in high-pass/low-pass filters. With the filter switched off, it can be
configured as a quasi 3-channel amplifier.
BUILT-IN ELECTRONIC CROSSOVER
You have a choice of selecting full-range, high-pass only or low-pass only. These filters feature
18 dB per octave high-pass and low-pass.
OVER-CURRENT, SHORT CIRCUIT AND DC OFFSET PROTECTION
The sophisticated circuitry monitors abnormal conditions such as voltage spikes, oscillation, DC
offset or short circuit. When any of these undesirable conditions exceed their respective preset
limits, the circuit will shut down the audio system briefly and lights up the protection indicator to
identify the problem for immediate attention. Once the problem is resolved, the amplifier will
resume operation automatically.
HIGH SPEED HIGH CURRENT HEXFET SWITCHING POWER SUPPLY
High current HEXFET transistors are used in the power supply section to minimize internal heat
and maximize reliability. Furthermore, the combination of the very high pulse-width-modulated
(PWM) switching frequency and the extra large filter capacitance guarantees stronger and
deeper transient bass response.
HIGH CURRENT/HIGH VOLTAGE FULLY COMPLEMENTARY OUTPUT STAGE
Complementary output stage audio circuitry has long been a hallmark of "exotic" home amplifier
design. Coustic is one of the very few car audio manufacturers to incorporate such elaborate
audio circuitry into its power amplifiers.
LINE OUTPUTS
The full-range line outputs can be used to feed signals to another amplifier for your future
expansion or for setting up a more sophisticated system.
WIDE RANGE INPUT SENSITIVITY ADJUSTMENT
The input sensitivity level of this amplifier can be easily varied from as low as 100 mV to as high
as 5.0 volts by adjusting the control on the End Panel.
HIGH/LOW IMPEDANCE INPUT
If you are using a floating or common ground car radio, this amplifier is the best fit for your
system. It is compatible with floating or common ground car radio speaker outputs even without
a floating ground adapter. If, in the future, you decide to change to a higher quality after market
source unit with RCA pre-amp outputs (like the Coustic CD527), this same amplifier is there to
give you improved frequency response and better sonic performance.
STABLE INTO 2-OHM LOADS
With the over-designed power supply section and a sophisticated power management circuitry,
these amplifiers can maintain their stability even in the highly reactive low impedance environ-
ment.
