Frequently Asked Questions - bit C2O AUDISON

What is the Audison bit C2O?

The Audison bit C2O is a compact car audio digital signal processor (DSP) designed to optimize sound quality by processing audio signals from the head unit and providing customizable equalization and crossover settings.

How do I connect the bit C2O to my car stereo?

Connect the bit C2O between your head unit and amplifiers using RCA cables. It accepts high-level (speaker wire) or low-level (RCA) inputs. Use the optical input for a digital connection if available.

Can I tune the bit C2O without a computer?

No, the bit C2O requires a Windows or Mac computer running the Audison Bit Tune software for full configuration. An optional remote control can be used for basic adjustments.

How many channels does the bit C2O have?

It has 2 analog inputs (stereo) and 6 analog outputs (Front, Rear, Sub, Center) plus a digital optical input. It can process up to 6 channels independently.

What is the maximum input voltage?

The bit C2O accepts input voltages up to 9V RMS on RCA inputs and up to 28V peak-to-peak on high-level inputs, making it compatible with most factory head units.

Does the bit C2O include a microphone for auto-tuning?

No, the bit C2O does not include a microphone. It is designed for manual tuning using the Bit Tune software. For auto-calibration, an external microphone must be purchased separately.

How do I reset the bit C2O to factory settings?

Connect the device to your computer, open the Bit Tune software, and select 'Restore Factory Defaults' from the settings menu. Alternatively, press and hold the 'Reset' button on the unit for 5 seconds.

Can I use the bit C2O with a factory sound system?

Yes, the bit C2O is ideal for aftermarket upgrades. It has high-level inputs that accept speaker-level signals from factory systems and removes factory EQ irregularities.

What is the warranty period?

Audison offers a 2-year warranty from the date of purchase for manufacturing defects. Proof of purchase is required.

How do I update the firmware?

Download the latest firmware from the official Audison website. Connect the bit C2O to your computer via USB and use the Bit Tune software's 'Update Firmware' feature.

USER MANUAL bit C2O AUDISON

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 (75Ω) 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 nullifying in this way any issues with interfacing.

FEATURES

The coaxial digital input is provided with an isolation transformer that improves the balance between the transmitter and the receiver circuit, reducing noise due to EMI electromagnetic interference, which is particularly insidious inside the passenger compartment.

The AUX-IN input is equipped with a pre-amplifier with adjustable gain of 0.1V ÷ 2V for an optimal coupling with each device before the Analog-Digital conversion is performed by a high quality converter at a resolution of 24 bit/48 kHz.

For maximum ease of use in cars, the C2O independently selects the input with priority assigned to the AUX-IN. With the default setting, after 6 seconds of no analog signal, the C2O moves to the coaxial digital input. An internal switch allows for the time before the switch to be set to 9 or 12 seconds.
