Special features:

Class GD technology

Audiotec Fischer´s proprietary Class GD concept takes the efficiency of conventional Class D amps to the next level. By varying the internal supply voltage in several steps depending on the amplifier’s input signals, idle losses are significantly reduced and overall efficiency is close to maximum at any time. So heat dissipation is almost negligible, thus allowing smallest heat sinks and most compact form factors.

ACO – Advanced 32 Bit CoProcessor

The ACO platform (Advanced CoProcessor) handles all control and communication tasks within the DSP system. It ensures extremely fast system startups, lightning-fast switching between up to ten sound setups, and provides the decisive speed boost, especially in data communication with our DSP PC-Tool software.  
ACO also serves as the foundation for a wide range of additional features – including SFX Sound Effects like “Augmented Bass Processing” and “RealCenter”, functions such as Dynamic Loudness Control (DLC) and Remote Tone Control (RTC), and a channel-separated input EQ with integrated Advanced Input Signal Analyzer (AISA) for easy analysis and correction of input signals with factory-applied equalization.  
ACO stands for maximum performance, flexibility, and future-proof system architecture. 

Smart highlevel input ADEP.3

Modern, factory-installed car radios incorporate sophisticated methods for diagnosing connected speakers. In particular, the latest generation of car radios is equipped with advanced monitoring functions, which can often lead to error messages or the loss of specific features (e.g., fader function) when a standard amplifier is connected. 
The ADEP.3 circuit (Generation 3) meets the demands of these advanced OEM systems and ensures seamless integration. Controlled by the ACO platform, the system is future-proof and designed to flexibly adapt to changes in vehicle radio diagnostics. 
This guarantees maximum compatibility with nearly all OE head units – without unnecessarily loading the speaker outputs at high volume levels.

Power Save Mode

The Power Save Mode allows to significantly reduce the power consumption of the amplifier (and any additional connected amplifiers) when no music signal is detected for a certain period of time.
When power save mode is active, the internal amplifier stages and the remote output are automatically switched off. Once a music signal is detected again, the device returns to normal operation within approximately 2 seconds. The switch-off delay can be adjusted or completely deactivated via the DSP PC-Tool software.

Automatic Digital Signal Detection

The amplifier allows signal-controlled switching between the analog inputs and the digital input. As soon as an input signal is detected on the Optical Input, the amplifier automatically switches to this input. This feature can be deactivated in the DSP PC-Tool software. Alternatively you can use an optional remote control for manual switching between analog and digital inputs.

Start-Stop capability

The switched power supply ensures a constant internal supply voltage even during short voltage drops down to 6 Volts (e.g. during engine start), so the functionality of the device remains stable and unaffected.
