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.

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-amplier 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.
