The GAN Series is ASCENDO’s comprehensive series of multichannel amplifiers for high-performance audio applications in markets where high channel count is required. Energy conservation is a major design goal for this range of products, which directly impacts CO2 emissions.

The power amplifiers are cutting edge multi-channel devices combining FPGA-based signal processing with advanced Class D power stages and universal power supply for global use. 

The use of a Power Factor Correction (PFC) results in a sinusoidal current consumption from the mains. The reduced mains harmonics no longer burden the power grid. Another effect is a much-improved power delivery from unstable mains.

These amplifiers diagnose themselves and provide information about channel and device status. The output current of all channels is measured and feed to a 20kHz detector. By using a pilot tone via the internal generator, the connection and voice coil of the speakers can be monitored.

Inputs are DANTE AES67, and outputs are Phoenix connections.

Their DSP sections:

• Adjustable limiter options. Limit the channel by current, voltage or power.
• FIR Filters are included to equalize the speakers or the acoustics of your listening room to a phase linear response. (Unlike IIR-Filters, you have the choice to adjust the phase response of the system.)
• To achieve simple and easy-to-use filtering, we also offer 32 IIR Filters per channel. These filters can be used to build crossovers and equalize the system.
• To adjust the time shift in your speaker system or the acoustic circumstances, every channel can be delayed up to 48000 samples, allowing more than 1 sec of delay time (approximately 330m of physical offset).
• Build read and write protected presets for specific speakers. Import, export and share them.

Extensive web-based user-interface:

• Control your ASCENDO GAN device with the shipped software. NO installation required.
• Use the overview page to watch and control every channel state.
• Create mute groups to mute multiple channels at once.
• Manage the input patching. Patch multiple inputs on each channel.
• Control device configurations, from network up to fan speed settings.
• Monitor channel events, peaks, level and more.
• Save, load, modify and import or export channel and device presets.
• Control the device from everywhere within the device network.
• Discover all GAN devices in the network, even across subnet boundaries. 
• Configure network settings for each device. 
• Identify individual devices and assign meaningful names. 
• Easy firmware updater for multiple devices. 
• Firmware manager which keeps you up to date.

Software integration:

• ASCENDO GAN devices provide an interface based on the REST standard to programmatically access and control all their settings and features. To simplify integration, an OPEN API documentation is provided which can be found on the devices webpage or on Github. 
• Partnership: We offer planning and implementation of automation solutions with LOXONE hard- and software. Integrate GAN devices seamlessly into a LOXONE environment. Control power, volume, mute, preset changes and many more settings.
