Many premium OEM sound systems use a common architecture: The source unit relays unprocessed audio signal to an amplifier, and also communicates with that amplifier on some data network connection. When the driver changes any audio setting of the system – volume, front/rear fade, bass/treble tone controls, etc. these commands are relayed on the network, and performed in the OEM amplifier. In addition, all vehicle-specific processing – phase, delay, and EQ processing – is performed in the OEM amplifier. The...

Some have been overwhelmed with the number of improvements in Audison AF Forza and bit Drive software.  We’ve often heard “where do we start? There are three big areas where Forza moves the category forward: 1 Power. Audison Forza 5-channel amp is now 1000 total watts RMS – over 2X the power! 100×4 at 4Ω, 600×1 @ 2Ω, RMS. The new AF Compact 8-channel is almost double the power of the model it replaces. The other amplifiers have similar increases....

    No category has been more confusing, or more disappointing, to in-car audiophiles than “high-resolution Bluetooth receivers”. Different handsets and different digital media players often deliver different sound-quality results, and it can be difficult to predict those results before the installation. Now, with the Audison B-CON audiophile Bluetooth receiver, you can guarantee performance. Audison B-CON is the first (and the only, at the time of this writing) Bluetooth 5.0® player designed for automotive use that has obtained the “Hi-Res...

Audison has engineered a system of BMW replacement speakers – a 200 mm shallow-frame under seat woofer, 100 mm midranges with 3-post aluminum cast frames, and Tetelon textile-dome tweeters. The midrange and coaxials are available in both 3-post frame sizes used by BMW and MINI. Connection is plug-and-play. The under-seat woofers are available in both 2Ω and 4Ω values, while the other speakers are 4Ω. The speakers can be used as replacements with OEM amplification, but the best results are...

For various reasons, OEM speaker outputs often have a muting protection circuit. Many of us have encountered this sort of muting behavior in OEM systems. Here’s some information about how it works. When the head unit turns on, the outputs are muted. This used to happen when the driver got in the car and turned on the ignition key. Today, it happens earlier – often when the user unlocks the door. This supports the vehicle’s use of the audio system to...

The bit Tune is an advanced measurement tool, and over the years it has evolved a few times, as we have added functions to it.         Some people who tried it years ago – often only to set up a bit Ten or bit One – haven’t ever seen the full feature set available to users today. Read on to learn what the bit Tune 3.1.0.1 SW can do for you.         ACOUSTIC REAL-TIME...

With this article we will understand why Audison Virtuoso 3.0 MPC (Mobile Phase Correction) technology is so important to achieve the highest listening quality in the car cabin. Sound waves have amplitude and phase characteristics. Amplitude is how powerful the wave is. The higher the pressure peaks, the louder the sound is perceived to be. Phase describes the timing of the wave – when the pressure peaks are occurring. Humans can often hear if the phase of the sound wave...

Dear Audison enthusiast, we wish to inform you that a major software and firmware upgrade for Audison bit One HD and bit One HD Virtuoso is available below: Virtuoso 3.0 web page The new release include the following features showing that even if you don’t have a bit Tune, the bit Virtuoso 3.0 gives the user advanced manual and automated tuning capabilities for both amplitude and phase:     – Built-in RTA with target curve support (display, creation, importing) and...

Audison_APM The development of Audison APM is the result of years of research and development into a complex topic, the evaluation of in-car sound quality. Many people in the industry have been talking about measuring acoustic performance without ever having achieved a tangible result up to now. The bit Tune hardware platform implements APM functionalities providing the market as well as industry specialists with a complete tool, enabling two innovative types of analysis which objectively evaluate customized and OEM car...

Audison bit Tune is the auto-calibration system for bit One HD Virtuoso for the setup of basic parameters (time alignment, equalization, levels, etc.), ensuring a correct acoustic result in a very short time. The bit Tune automatic routine also includes the diagnosis of common connection “errors” (channels/phase inversion, no signal from a channel/cable, etc.), to set the specialist free from his “routine” work and allow him to focus on the art of “fine-tuning” while listening.   Audison_bit_Tune   Thanks to...

The bit One HD Virtuoso is provided with advanced features for the integration with OEM infotainment and a purely audiophile vocation. The ability to independently configure the equalization for the MASTER and AUX inputs allows the user to create two separate systems without using different memory presets, the one dedicated to listening to the OEM Head Unit and the audiophile one to achieve maximum audio performance, in both cases preserving all the Head Unit functions (gong signal, alert, phone …)....

bit-One-HD-Virtuoso-RVA The bit One HD Virtuoso further improves its integration level with OEM Head Units with the RVA (Remote Volume Aux) function. This exclusive technology provides the ability to select an auxiliary source (I.e.: a HI-Res audio player or auxiliary wireless interface connected by digital inputs) and adjust its volume via the OEM Head Unit, offering full support to the management of the car priority signals such as parking sensor alerts, GPS messages, phone and vocal commands whilst music is...
