4. DETAILLED DESCRIPTIONS
4.1 LEFT SIDE PANEL
The left side contains the three Mic/Line inputs with their respective function switches as illustrated below, and
also a stereo BUS Input and the DC connector for the external power supply.
4.1.1 Mic/Line inputs [ IN1 à IN3 ]
Each of the input channels is transformer-less, electronically balanced, and is equipped in standard with a RF
Filter. They correspond to the input channels 1 to 3 on the front panel.
Input connectors are standard XLR-3 female where:
Pin1 = Gnd / Pin2 = High (+) / Pin3 = Low (-).
To connect an unbalanced source such as CD Player, Minidisk or else, pin 3 must be bridged to pin 1 (Gnd) and
wired to the Gnd on the source. Then use pin 2 for the unbalanced input signal.
WARNING:
Never use the [48V] Phantom in case of unbalanced connection or you could severely damage the
sourcing device !
4.1.2 Phantom power [ 48V ]
This switch turns the 48V Phantom power On or Off on the corresponding channel [IN1 à IN3]. In lower position
the 48V phantom is turned On to power condenser microphone. In upper position the Phantom power is turned Off
for connection of Dynamic microphone or any other analogue sources
WARNING:
Never use the 48V Phantom when an external device other than a condenser microphone is
connected to the input or you may severely damage the output circuitries of that device.
Never use the 48V Phantom in case of unbalanced connection.
NOTE:
Almost all modern condenser microphones of the latest generation are operating under 48V
Phantom power. Because of the excellent common mode rejection (CMRR) it has been decided to
include only this kind of microphone powering on the SX-M32.
