. . to the Coustic world of power These new Coustic 321QE and power amplifiers deliver the cleanest environment. Besides their sleek contoured design, the and most sophisticated audio features. This features. For the best sonic reproduction, please as closely as possible. The time you spend 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 Whatever you need for your ultimate car audio system, look audio components to meet the most critical demands. Coustic . . . a sound investment.

Please take a moment to register your purchase on line @ coustic.com. Please also record the serial number of your amplifier in the space provided below and keep this manual for future reference, as well as your sales receipt as proof of ownership. (The serial number of your amplifier is marked on the bottom of its metal chassis.) Serial Number: Date of Purchase: FEATURES BUILT-IN ELECTRONIC CROSSOVER ADJUSTABLE CROSSOVER FREQUENCIES An electronic crossover has many advantages yetmore flexible system design, lower distortion and higher gain structure. The 321/poweramplifiers are equipped with built-in 18dB electroniccrossovers. The front and rear channels can be orlow-pass applications. OVER-CURRENT, SHORT CIRCUIT AND DC OFFSET PROTECTION The sophisticated circuitry monitors abnormal conditions such as voltage spikes, oscillation, DC or short circuit. When any of these undesirable conditions exceed the circuit will shut down the audio system briefly and lights identifythe problem for immediate attention. Once the problem is resolved, automatically. HIGH SPEED HIGH CURRENT MOSFET SWITCHING POWER High current MOSFET transistors are used in the power supply section heatand maximize reliability. Furthermore, the combination of the very high pulse-width-modulated(PWM) switching frequency and the extra large filter capacitance guarantees deepertransient 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 amplifierdesign. Coustic is one of the very few car audio manufacturers to incorporate such elaborateaudio circuitry into its power amplifiers. Triple Darlington configuration ensures the audio amplifieris 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 expansion or for setting up a more sophisticated system. WIDE RANGE INPUT SENSITIVITY ADJUSTMENT The input sensitivity level of the Coustic 321/481QE amplifiers can be easily varied from as lowas 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 unitsthat do not have RCA or line level outputs. The audio signal can be obtained by simply connecting the amplifiers speaker level input wires to the head units speaker level outputs wires. If you areusing 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 groundadapter. ADJUSTABLE BASS BOOST This feature allows you to enhance the bass performance of your sound system. The control is continuously variable with a maximum boost level of 18dB. REMOTE SUBWOOFER GAIN CONTROL PORT (R S) The 481QE 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 fluctuationsin a moving vehicle. MULTI-FUNCTION PROTECTION INDICATOR When the red protect indicator lights up it signifies a high operating temperature is detected andthe amplifier is temporarily shut down to allow for a cooling period. As soon as the temperaturereturns 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, shortedspeaker outputs or a DC offset at the outputs. Turn off the amplifier, double-check all inputs andspeaker connections to make sure there is no short or inappropriate inputs. If all connections are inorder, turn on the amplifier to resume operation. 3 COUSTIC.COM CONTROLS, INDICATORS, AND TERMINALS INPUT PANEL FRONT REAR SPKR LEVEL L R REMOTESENS MIN MAX MODE HPF OFF LPF FREQ 30 300 60 180 0 +18 BOOSTSENS MIN MAX MODE HPF OFF LPF FREQ 30 300 60 180 0 +18 BOOST OUTPUT FRON...
