The Audison AFC CLK accessory is specifically engineered for the Audison Forza Compact amplifier line. This accessory kit comprises a metal bracket equipped with air flow slots and a cooling fan, which can be securely mounted onto the Audison Forza Compact amplifiers.
Key Features:
• Durable Metal Bracket: The sturdy metal bracket ensures reliable support and optimal airflow through strategically placed slots.
• Efficient Cooling Fan: The cooling fan is equipped with a temperature sensor, allowing it to activate only when the amplifier requires additional cooling. This ensures efficient operation and prolongs the lifespan of the amplifier by preventing overheating.
• Temperature Sensor: The intelligent temperature sensor continuously monitors the amplifier’s temperature, activating the cooling fan only when necessary, providing efficient and effective cooling precisely when needed.
The Audison AFC CLK accessory is highly recommended when the amplifier is installed in very tight spaces with limited air circulation, ensuring optimal performance and longevity under challenging conditions.
Features
- Improved audio performance and power thanks to the latest generation of ADT (Audison D-Class) technology
- Unbeatable power/volume ratio up to 0.47 W RMS/cm³ reaching 81% of efficiency
- Hi-Res compatibility performance, with an extended audio band up to 40 kHz
- Maximum versatility thanks to the possibility of using the bridging option for each pair of power outputs
Technologies
ADT uses a switching frequency twice as fast as many other modern Class D amplifiers using very high-tolerance component parts to keep the timing correct even during temperature extremes. The higher switching frequency of Audison Class D moves noise much farther away from the audible band. Audison Class D amplifiers also use a steeper 4th-order analog lowpass filter, rather than the simpler 2nd-order lowpass filters usually used in competing designs. The steeper filter will keep noise much lower in amplitude – which is good for controlling EMI and preventing infrasonic noise from getting to the tweeters. It also keeps phase shift outside the audible range. The cost is higher – twice as many components are needed for a 4th-order filter compared to the usual 2nd-order filter, and each output channel needs its own filter – but Audison determined through exhaustive listening testing that this design was the best-sounding approach.
The “All Channels Driven” design philosophy guarantees that the Audison amplifier delivers the rated power on all channels simultaneously. To reach that target, Audison designed the amplifier power supply to handle the cumulative power demand.
Maximum versatility thanks to the bridging option for each pair of channels.
According to the definition of Hi-Res audio provided by JAS (Japan Audio Society), this amplifier exceeds the above 40 kHz bandwith analog requirement.
Universal Speaker Simulator technology on high-level inputs for maximum compatibility with any type of Head-Unit OEM Source.
