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.

160SE specifications

The Coustic 160SE is a powerful and versatile audio amplifier that has gained popularity among audio enthusiasts and professionals alike. Designed to offer superior sound quality and robust performance, the 160SE is well-suited for various applications, ranging from home theater setups to professional sound reinforcement.

One of the standout features of the Coustic 160SE is its impressive power output. Capable of delivering up to 160 watts per channel into 4 ohms, this amplifier ensures that users can enjoy rich and dynamic audio reproduction. This level of power provides ample headroom, enabling the 160SE to handle demanding soundtracks and intricate audio with ease. The amplifier's low total harmonic distortion (THD) rating guarantees that the audio remains clean and undistorted even at high volumes.

The 160SE employs advanced circuit design and high-quality components to maximize its performance. The use of high-grade capacitors and inductors contributes to improved efficiency and sound clarity. Additionally, the unit features a built-in thermal protection system that safeguards the amplifier from overheating, ensuring long-lasting operation and reliability.

One of the key technologies present in the Coustic 160SE is its class AB amplification. This design combines the best aspects of class A and class B amplifiers, resulting in improved linearity and reduced distortion while maintaining efficiency. Users will appreciate the warm and natural sound signature that is characteristic of class A/B designs. The amplifier also includes variable crossover controls, allowing users to tailor the sound to best fit their specific audio needs.

The Coustic 160SE is equipped with multiple input options, including both low-level RCA inputs and high-level (speaker wire) inputs, making it compatible with a wide range of audio sources. The rear panel features comprehensive binding posts for easy speaker connections, as well as gain controls for each channel, enabling precise level adjustments.

For those seeking an amplifier that combines power, versatility, and quality, the Coustic 160SE stands out as an excellent choice. Its robust features, coupled with its advanced technologies, ensure that it delivers a stellar audio experience for both casual listeners and audiophiles alike. Whether used in a home audio system, for live sound monitoring, or in a professional studio, the 160SE is designed to meet and exceed expectations.
