Audison BIT C20 Converts Coaxial Digital Iinput TO A Toslink Digital Output

Audison BIT C20 Converts Coaxial Digital Iinput TO A Toslink Digital Output

USE

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.

PRODUCT 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 an 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.
