Product Description

AUDISON - SR 1Dk

 

     AUDISON SR 1Dk is a powerful mono Digital amplifier representing maximum expandability in terms of power and configuration capability. Featuring a PRE OUT recreated from the hi-level speakers inputs and by-passable full configurable crossover along with its abillity to operate in "cascade" mode linking many amplifiers together, its extreme versatility makes it a premium product.
 
 
 
 
 

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.

 

Solid Aluminium

Solid aluminium heatsink construction.
