Features and Benefits

The Datasat AP25 is an extremely comprehensive digital signal processing (DSP) solution for cinema with an outstanding range of features available in a single chassis.

16 channels of digital audio

With 16 channels of digital audio available as standard, the AP25 leverages the power of six Analog Devices 400MHz DSPs. In addition, it includes one S/PDIF, two TOSLINK and four HDMI 2.0b inputs with Blu-ray decoding to provide the ability to handle widest range of professional and consumer content. Its channel support allows the AP25 to accommodate the standard 5.1 digital surround up to and beyond the 11.1 and 13.1 sound formats required for the next generation of 3D audio.

Extensive equalization functionality

The AP25 comes with 31 bands of third octave and three bands of parametric equalization on every channel. In all, the AP25 delivers 512 individual equalization bands. In addition, each channel includes low, high and bandpass filters as well as individual treble and bass controls to deliver a stunning clarity of sound.

Market-leading room optimization

The AP25 takes advantage of Datasat’s exclusive licensing of Dirac Live room optimization technology for the cinema industry. This makes the AP25 the only cinema audio processor to include true working mixed-phase correction. In addition to impulse response optimization, you receive advanced tools to correct issues in both the time and frequency domains including magnitude response correction, early reflection reduction and bass management.

Restored sound stage

The advanced room optimization technologies in the AP25 combined with its audio equalization and audio delay capabilities allow you to deliver a sound stage that is transparent and true-to-source. Regardless of room design or speaker arrangement, you’re able to tune the listening environment to provide the optimum experience whatever content type is being played.

Multiple memory presets

Every facet of a properly tuned room is captured and stored. The room can be tuned to optimize different content types. The memory presets can then be used to switch quickly between set-ups as the content changes without having to re-tune the room. In addition, all presets can be saved to a USB memory stick. This provides security in case of failure but also allows for the rapid tuning of new rooms. In new cinema construction where all rooms are designed to be identical, you an use one audio processor to tune the initial room, save this to the memory presets on the USB stick and tuning the next room becomes as easy as downloading the memory presets onto that room’s processor.

Ease of management

The AP25 presents you with a number of features to make management flexible and convenient. In addition to a range of wireless remote control options – including smartphone, tablet and laptop support – the system includes Ethernet and RS232 connects with up to 20 user-defined set-up and operational profiles.
