Box Content
Provided control interconnection to control memory selection and remote power-on.
Provided cable with eight pairs of labeled cables to connect the speakers to the AF M12.14 bit.
Eight stereo RCAs interconnection to connect Forza bit amplifier with after-market sources with PRE-OUT outputs provided with Forza amplifiers.
Provided cable with 8 pairs of labeled wires to connect Forza bit amplifiers bit with the high-level output of OEM sources.
Accessories
The F2O accessory is a digital input extension card, compatible with the new line of Audison AF bit amplifiers with integrated Dsp.
The card fits the dedicated external slot of the AF bit amplifier and it adds an additional Coaxial S/PDIF or a second Toslink S/PDIF input. The type of additional input can be selected by the switch mounted over the card itself.
In case the Coaxial S/PDIF input is selected, it is possible to use the Coaxial input cable included in the card box.
The F4IN accessory is an analog input extension card, compatible with the new line of Audison AF bit amplifiers with integrated Dsp. The card fits the dedicated external slot of the AF bit amplifier and adds four analog high-level input channels to the AF bit native eight, thus reaching twelve high-level (SPK IN) inputs.
With respect to the sensitivity range of the AF bit native eight SPK IN inputs (2.2 ÷ 22 VRMS), the F4IN features 3.2 ÷ 32 VRMS to allow a perfect integration in advanced OEM systems with higher voltages.
AF LINK accessory cable can be connected to have 6 additional channels configurable on the bit Drive software.
This Plug&Play T-Harness provides the ability to install an Audison AF bit amplifier on BMW vehicles equipped with RAM module. It is compatible with “Standard” and “Hi-Fi” sound system. The OEM seven-channel amplifier is connected via a forty-two pin multipolar connector.
AFBMW ReAMP 3 allows AF Forza user to:
- Retrieve the OEM source front mid/high, rear mid/high, underseat low-pass and center signals;
- Route the AF bit amplifier outputs to each of the OEM amplifier seven channels: (Mid-Hi FL; Mid-Hi FR; WF FL; WF FR; RL; RR; Centre)
- The Plug&Play terminals enable the user to choose which AF bit output to connect to each of the seven channels of the OEM audio system
- It is also possible to bridge the outputs of the AF bit amplifier
- Keep the OEM amplifier on.
The AFBMW ReAMP 3 can also be used with the Audison AP F IN ADP accessory (not included in the box) for full Plug&Play connection to an AP F8.9 bit amplifier.

Technologies
Next-generation bit Drive software platform – developed for this family of products – simplifies every control and function.
Native DSP working at 24 bit/96 kHz and an extended audio band up to 40 kHz.
The acoustic analysis integrates the response graph into the equalizer display ensuring efficient tuning and great sound, compatible with any 24-bit USB microphone.
The electrical analysis integrates the response graph into the input equalizer display, ensuring efficient tuning.
Electrical Signal Analysis ensures proper integration and correction for each input channel.
Enjoy the improved audio performance of the latest generation Audison D-Class technology.
Maximum versatility thanks to the bridging option for each pair of channels.
Forza amplifiers have two independent power supplies: the audio amplifier power supply is loosely regulated, which allows superior dynamic performance. The DSP power supply is stiffly regulated, which maintains DSP microprocessor operation even during lower-voltage transient states (i.e., start/stop operation).
Quick I/O Configuration speeds up system definition and signal routing.
When connected with Audison B-CON hi-res Bluetooth receiver, this feature manages the Master Volume of the Forza amp thus ensuring full dynamic range signal at the input.
iDatalink Maestro AR native support for a total integration with OEM infotainment.
Equipped with eight analog inputs, to support total connectivity even with the most complex OEM systems.
Automatically sums and reverses OEM equalization.
Input delay compensation of time-delayed factory outputs prior to signal summing.
Allows left and right inputs to match in phase before tuning, even if OEM phase processing has been used.
Universal Speaker Simulator technology on high-level inputs for maximum compatibility with any type of Head-Unit OEM Source.
14 DSP-processed output channels for a total control.
A New, Comprehensive Approach
THE FUTURE OF AUDISON BIT CONFIGURATION SOFTWARE
With bit Drive, Audison delivers the DSP software of the future. It configures itself for each product it controls, allowing it to control bit products we haven’t even imagined yet!
New Graphical User Interface
a technician’s most powerful tool
Improved user controls
for selecting frequency, channel, slope, and bandwidth
Infotip support
hover the cursor overan icon to see its definition
Integrated help
each core functional areacontains one-click guidance
Color-coded linking
of the interface controls to the selected channel keepsthe technician always focusedon the proper channel.
Integrated electrical and acoustic measurement and analysis without leaving the application
(compatible USB microphone required for acoustic RTA function)
Bit Drive is the future.
Even though we’ve modernized the user interface, key operations are still where Audison veteran dealers expect to find them – but info tips for new icons and embedded help files assist first-timers. The Configuration Wizard makes setup faster than ever, and Audison R&D has upgraded the OEM Integration section and the acoustic Tuning controls section with more powerful tools and capabilities.
