Product Description
AUDISON - SR 5
INTERNAL
Output Transistors
Bipolar design, featuring high-speed TO247 Fairchild transistors, provides audiophile sound quality and bursting dynamics.
Dynab
Monitors the operating conditions of the amplifier, while automatically and constantly adjusting the bias current for the best possible sound quality in every condition.
Audison LNS™ Circuitry
Used to eliminate the electromagnetic disturbances found in today’s vehicles, preventing them from being induced into the input section.
RFI Filter
Used to eliminate the “Radio Frequency Interference” noise generated from the power supply and along the power and ground cables being transferred to external device, for noise free operation.
Power Supply Toroid
Multi-winding power supply toroid supplies current for the amplifier.
High Current Fuse
High current fuse is designed for the “impulsive” current demands of music.
Power Terminals
Up to 4 AWG cross-section wire required for the proper current transfer to the amplifier.
Low-Level Inputs
Low level inputs are provided for each channel, directed to a "pre-out" to feed input signals to other components.
Hi-Level Inputs
Each amplifier channel is provided with a hi-level input, with the ability to direct the signal to a low-level output for added system design flexibility.
EXTERNAL
Rotary Dial Controls
All level and crossover adjustments are controlled via a rotary potentiometer for accurate settings. All crossover functions are easily configured for virtually any system design, as well as being fully by-passable.
Top Mount Fuse
For visual check, the high current fuse is mounted on the top panel and can be quickly and easily replaced.
Status Indicator
The logo illuminates blue under normal operating conditions and turns red when the protection circuitry is engaged, easily identifying the amplifier status.
Convection Cooling System
Intakes fresh air, circulating this "cool" air through the amplifier and exhaling the "hot" air through the vent on the top of the amplifier. This keeps the amplifier cooler for extend listening pleasure in every installation position.
