FEATURES
An electronic crossover has many advantages over passive crossovers - lower cost, simplified yet more flexible system design, lower distortion and higher gain structure. The 401DB/801DB power amplifiers are equipped with
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 the protection indicator lights up 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
D-BLOCK TECHNOLOGY
This proprietary class D output stage is used to deliver maximum power with minimal current draw from the vehicles electrical system while eliminating traditional class D interference.
LINE OUPTUTS
The
WIDE RANGE INPUT SENSITIVITY ADJUSTMENT
The input sensitivity level of the Coustic 401DB/801DB 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 amplifiers feature
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.
DEFEATABLE SUBSONIC FILTER
This feature allows you to maximize the amplifier’s ouput when a specifically tuned subwoofer sys- tem is needed.
REMOTE SUBWOOFER GAIN CONTROL PORT (R S)
This amplifier has a
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
