ES3
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.

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.
