Coustic 401SE, 601SE, 241SE owner manual Welcome, Features

WELCOME

. . . to the Coustic world of power and clarity. The new 241/401/601SE amplifiers deliver the cleanest music you’ve ever heard at any power level in the 12-volt environment. Besides the sleek contoured design, the 241/401/601SE 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 follow the installation suggestions and recommendations as closely as possi- ble. 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 dynamic full-range speakers or subwoofers and electronic crossovers.

Whatever you need for your ultimate car audio system, look to Coustic - for a wide range of car audio components to meet the most critical demands.

That’s because . . . COUSTIC ROCKS!

FEATURES

BUILT-IN ELECTRONIC CROSSOVER WITH CONTINUOUSLY ADJUSTABLE CROSSOVER FREQUENCIES

An electronic crossover has many advantages over passive crossovers - lower cost, simplified yet more flexible system design, lower distortion and higher gain structure. The 241/401/601SE power amplifiers are equipped with built-in 18dB per octave continuously adjustable electronic crossovers that can be configured for full-range, high-pass or low-pass applications.

OVER-CURRENT, SHORT CIRCUIT AND DC OFFSET PROTECTION

The sophisticated circuitry monitors abnormal conditions such as voltage spikes, oscillation, DC off- set 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 oper- ation automatically.

HIGH SPEED HIGH CURRENT MOSFET SWITCHING POWER SUPPLY

High current MOSFET 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.

TRIPLE DARLINGTON 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. Triple Darlington configuration ensures the audio amplifier is always operating at its optimum conditions.

LINE OUPTUTS

The full-range line outputs can be used to feed signals to another amplifier for your future expan- sion or for setting up a more sophisticated system.

WIDE RANGE INPUT SENSITIVITY ADJUSTMENT

The input sensitivity level of the Coustic 241/401/601SE amplifiers can be easily varied from as low as 100 mV to as high as 5.0 volts by adjusting the control on the Input Panel.

LINE LEVEL AND SPEAKER LEVEL INPUTS

These ampliifers feature pre-amp inputs for use with head units that have RCA or line level outputs. These amplifiers also feature speaker level inputs allowing the amplifier to work with head units that do not have RCA or line level outputs. The audio signal can be obtained by simply connect- ing the amplifiers speaker level input wires to the head units speaker level outputs wires. 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.

ADJUSTABLE BASS BOOST

This feature allows you to enhance the bass performance of your sound system. The control is con- tinuously variable with a maximum boost level of 18dB.

REMOTE SUBWOOFER GAIN CONTROL PORT (R S)

This amplifier has a built-in remote subwoofer level control input port. With the optional R S remote control, the subwoofer output level can be adjusted to compensate for bass fluctuations in a moving vehicle.

MULTI-FUNCTION PROTECTION INDICATOR

When the red protect indicator lights up it signifies a high operating temperature is detected and the amplifier is temporarily shut down to allow for a cooling period. As soon as the temperature returns to a safe level, the amplifier will restart and resume normal operation.

This indicator also lights up when the amplifier detects either an over-current situation, shorted speaker outputs or a DC offset at the outputs. Turn off the amplifier, double-check all inputs and speaker connections to make sure there is no short or inappropriate inputs. If all connections are in order, turn on the amplifier to resume operation.
