Note: In case of use specific coupling the limiters are coupling together, which
is the required mode for applying simultaneous and identical gain reduction to
both channels in « stereo » and M/S modes, in order to preserve the coherence
of the stereo image.
2.1.2. Line inputs/return
Two inputs are available on a 5-pin female XLR socket, and are electronically
balanced. It is possible to unbalance an input without negative impact on the
performance. Each channel has its own maximum level adjustment in the menu
from -9dBu to +22dBu (for 0dBFS). Theses inputs can be use as a return from
video camera but can be use as more analog entries for the mix down or the
recorder. It is possible to have a fader control on each input through P1 to P4. In
this case, we provide you 15dB more gain.
Theses inputs have digital high-pas filtering, 50 Hz to 200Hz 12dB/octave and
300 Hz, 6dB/octave, suitable for compensating proximity effects in directional
microphones
2.1.3.
Embase “EXT I/O”, Récepteurs HF
The “EXT I/O” socket is available for the connection of an optional
extension box. This device can be used to interface 4MINX with radio
transmitters and/or receivers.
When the extension device is plugged into the “EXT I/O” socket, the
mixer can use, for channels 3 and/or 4, inputs from the EXT I/O socket instead
of XLR inputs 3 and 4. In this case NO microphone power is apply on these
inputs.
The extension device feeds these inputs with two balanced signals. For
safety, no microphone powering is inserted into these inputs on the EXT I/O
socket
but all others settings are the same.
On this interface, you have 2 asymmetrical outputs. Theses outputs are
described on the need paragraph.
Note: A 9V/ 600mA power supply is available on the connector.
