ES3

It prevents the processor from shutting down when turning on vehicles featuring the start & stop system. When starting the engine, the vehicle battery voltage might decrease below 8 Volts value. If a signal processor (bit One, bit Ten) is installed in your system, especially with vehicles featuring the start & stop system, low supply voltage values might make the processor shut down. In order to avoid waiting for the processor to complete its turn-on cycle again, you can install the ES3 by connecting it in series to the processor power supply cables.

The Bit DMI is a high-quality digital interface designed to connect the original digital sources of a vehicle with Audison signal processors, ensuring a signal transmission free from disturbances and without loss of quality. This device allows you to maintain the original functionalities of the vehicle's audio system while integrating high-end audio solutions for a superior listening experience.

The Bit DMI is compatible with the digital systems of major automotive manufacturers, thanks to its ability to convert native digital signals into signals compatible with signal processors. This ensures a faithful audio reproduction, preserving the integrity of the original sound and enhancing its quality through the advanced signal management provided by Audison processors.

Installing the Bit DMI is simple and non-invasive, designed to integrate perfectly with the vehicle's onboard electronics without compromising the original functionalities of the system. Moreover, its compact and discreet design allows for flexible installation in different types of vehicles, without requiring substantial modifications.

In summary, the Bit DMI is an ideal solution for those who want to enhance their vehicle's audio performance while maintaining compatibility with the original systems, ensuring excellent sound quality and perfect integration with the existing instrumentation.

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

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.

STR

Male-Female Toslink adapter with rotating head. 90° angle shape to save space.

ECK DRC

It is a kit composed of a cable and an adapter allowing a 2 m / 78.74 in. Additional extension of the cable supplied with the DRC. This extension is required for installations on especially long vehicles such as SUV. Total length of the supplied cable with the extension is equal to 6,5 m / 225.90 in.
