FEATURES
BUILT-IN ELECTRONIC CROSSOVER
An electronic crossover has many advantages over passive crossovers - lower cost, simplified yet more flexible system design, lower distortion and higher gain structure. The 161SE power amplifi- er is equipped with
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 lim- its, the circuit will shut down the audio system briefly and lights up the protection indicator to iden- tify the problem for immediate attention. Once the problem is resolved, the amplifier will resume operation 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
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.

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 Input Panel.

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
