Enjoy the new SR: style and performance
The new SR range was created for the enthusiasts who want to enter into the world of car audio through an amplifier of excellence: an amplifier which satisfies their quality, power and cosmetics desires. In terms of electronics and mechanics, the SR project is the best available product in its class; balancing size, versatility, power and, like all Audison products, sound quality.
For the final stage of the amplifier, the proprietary DYNAB (Dynamic AB) Class circuitry was employed, automatically managing bias current without the need for complex adjustments. DYNAB merges the simplicity of the traditional B Class amplifier with the qualitative benefits of an AB Class amplifier. Essential in the SR project is the use of the latest generation high speed TO247 transistors, fixed to the heatsink with a new spiral spring system. Smooth, dynamic sound; an Audison philosophy.
Solid Aluminium Heatsink
Internal amplifier components can reach temperatures of 90°C (194°F) or more. This is why Audison chose
to create the heatsink and related parts from aluminium; a material which has no peer in terms of heat dissipation and light weight.
Level Virtual Heatsink
Electronics and mechanics merge into the new SR to create full synergy, giving form to the 2-Level Virtual Heat sink; a system
which allows the amplifier to perform longer, even as it reaches high temperatures. The SR delivers maximum power, even under demanding thermal conditions, without deteriorating the sound quality.
Unconventional in the car audio world, and approved by the most important international security regulatory authorities, the terminal blocks of the SR feature a rising clamp system, preventing the cable from damage. The new guided wire insert system accepts cables up to 4 AWG for the power supply and up to 8 AWG for the loudspeakers with easy, intuitive, safe and secure connection.
Top Panel Controls
According to the tradition of Audison, the controls for operating modes, input sensitivity and crossovers are found along the top panel of the amplifier, protected by the hinged cover plate. All crossover filters are entirely independent and are by-passable, allowing system design versatility. Also featured is the built-in remote volume control circuitry.
Hi and Low-Level Inputs
With its hi-level input, the new SR can be interfaced with virtually any factory OEM system or other source units without low-level outputs. The high level input also features ARTTM, negating the need for a remote turn on signal from the source. Being the only one within its market range, the hi-level speaker input signal can also be output through the PRE OUT RCA terminals. Both the low and the hi-level signal inputs incorporate the LNSTM circuit to eliminate electrical disturbances found in the car environment. These features allow you to expand any system with the highest possible sound quality.
