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-amplier 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.
