6 MIXY - User Manual 55 000 057 - B
2.3. USB and auxiliary Return/Line In
MIXY also has auxiliary two-channel inputs that can be routed to the mix buses,
and/or monitored on the display and the headphone:
x USB: this interface brings a digital 2-channel signal, that is converted to
analog ; no gain adjustment is needed!
x Line In: two-channel input on a 5-pin female XLR (
15 ); balanced signals,
but unbalanced inputs can be used as well with no performance loss. A
gain adjustment is available in the menu in order to match the maximum
level with the clipping level of the internal A/D converter (0 dBFS).
The maximum level, that corresponds to 0 dBFS, is adjustable from -9 dBu
to +22 dBu., separately for each channel.
2.4. Analog outputs
2.4.1. Main outputs “Line Out”
The L and R mix buses are output on a male 5-pin XLR socket (
16 ).
The signals are electronically balanced; they can be unbalanced with no
impact on performance, as long as the level stays below +19 dBu.
The maximum output level (which corresponds to the maximum digital level,
0 dBFS) is adjustable via the menu, from -9 dBu to +22 dBu.
Also via the menu, a 40 dB attenuator can be inserted on each output
channel, so providing a “microphone level” signal.
It is also possible to use a dedicated coding matrix and encode or decode
the signals from/to a [normal] “stereo” or “M/S” mode.
As just one example, one can get normal stereo outputs while the buses
and digital outputs are M/S encoded. In this case, the following matrixing
takes place:
x L output = Bus L + Bus R (here Bus L and Bus R are M/S
encoded)
x R output = Bus L – Bus R
