AP8.9 bit DSP Amplifier | 520 W | 9 CH DSP + 8 x 65 W @ 2 ohm | D-class Fully Bridgeable

The AP8.9 bit amplifier was designed by Audison R&D Department to achieve maximum sound quality in OEM Integration applications. The powerful management software proves the ability to acquire the bit Drive presets which the Audison team fine-tuned specifically for your car. Thanks to the innovative power supply stage, a power of 520 W total can be achieved in an extremely compact case. The non-amplifiable ninth channel can be used to drive a subwoofer via the mono AP1 D amplifier.

DRC MP
DRC MP
The new Audison DRC MP (Digital Remote Control Multimedia Play) is compatible with all the Audison electronics featuring AC Link bus. Its slim profile along with the holder supplied with it eases the installation in the best position inside the car. Thanks to the new Joystick, Rubber Touch finished for best control of the movements along the four direction axes, the DRC Settings menu can be adjusted and navigation is also possible through the Navi Comm and function if the system features an Audison bit Play HD with video output connected to a monitor.

DRC AB
DRC AB
DRC AB enables the main system control (volume, balance, fader and subwoofer volume, bass-boost) without the use of a PC. Thanks to this device, installed in an ergonomic position within the car dashboard, the user can: choose between the four DSP presets and select the source among master, auxiliary and the two optical digital inputs.

C2O
C2O
The C2O interface converts the signals coming from the coaxial digital input and from the analog AUX-IN into a TOSLINK optical digital output signal (up to 24 bit/192kHz). The conversion allows the integration of the new Hi-Res portable devices equipped with coaxial digital output (75 ohm) and smartphones with analog output on 3.5 mm mini Jack (also 4 poles) with Audison processors featuring an optical digital input compatible with the resolution of the signal sent to the C20. Thanks to its extreme compactness, the C20 can be installed in a hidden position on the dashboard, drastically reducing the length of the cabling between the portable player and the receiving device.

bit DMI
bit DMI
bit DMI is a digital interface for MOST systems, providing the ability to connect the Audison bit processors and the Audison amplifiers, equipped with digital input, to OEM multimedia systems in cars featuring the MOST technology based on optical fibre. Thanks to the digital connection, the signal can be transmitted without loss of quality, keeping the audio controls built in the OEM head unit “ such as volume, balance and tone controls as well as the hands-free kit, navigation system and parking sensors alerts unaltered.

bit Tune
bit Tune
The Audison bit Tune is a revolutionary system of automatic calibration for Audison bit processors developed with bit Drive technology. Bit Tune also includes a multitude of additional features for electro-acoustic verification and analysis of any car audio system.The Audison team s goal in developing the bit Tune was to speed up the setting of basic parameters for the calibration of the bit processors (time alignment, equalization, levels, etc.), ensuring an excellent level of acoustic performance. This phase also includes the diagnosis of comm on errors (channel inversion/phase, no signal on one channel/cable, etc.) to set the specialist free from his routine work and allow him to focus on the art of fine-tuning. Only personal interpretation and experience can achieve what a machine could never do: create Your Sound!

SPM4
SPM4
Stereo passive mixer (unpowered) featuring 4 input channels and 2 output channels, designed for active OEM multi-way systems where each speaker is powered by one specific amplified channel. SPM4 mixes audio through 4 audio transformers specifically developed to achieve very low distortion and highly linear acoustic response. SPM4 provides the ability to mix the midrange/woofer and tweeter channels coming from the amplifier and supply one single mid-high channel. The Ch1(L/R) channels feature two inputs, one features an inverting input compared to Ch2 (L/R) channels; the mixing process often gives better results when one of the two channels undergoes a 180° dephasing. SPM4 is especially recomm ended to extend the number of inputs of the Audison digital processors or amplifiers with built-in DSP because they feature a De-equalizer (De-Eq). In that case, any possible non-linear acoustic emissions due to the mixing of the pre-existing filtered channels are duly compensated.

USS4
USS4
Some OEM sources/head-units have a test circuit that monitors the presence of a low-impedance load to enable audio outputs. When you connect this type of head-unit to the high-level inputs of an Audison bit processor, which has a high impedance load, audio outputs are silenced. By inserting the USS 4 between the source and the processor / amplifier, these problems are definitively solved.
