MIC INPUT
Dynamic, condenser or tube microphones can be connected to
the MIC input. The 48 V switch provides the phantom power
necessary for some microphones (see also „Control elements/
Phantom“ on page 16).
The MIC input can also be used as a balanced connection for
professional audio equipment with a maximum output level of
+20 dBu.
IMPORTANT NOTE: Always switch the phantom power (48 V)
off before connecting anything other than phantom-powered
condenser microphones.
HI-Z/LINE INPUT
The instrument input HI-Z/Line Input is for electric guitars
and basses or other high-impedance, line-level signals such
as keyboards, samplers, drum machines etc. with unbalanced
outputs. If a balanced connector (TRS) is inserted, the ring of
the plug is automatically connected to the ground to ensure
proper unbalanced operation.
ANALOG OUTPUTS 1/2
The preamplified output signal is fed to the balanced Analog
Outputs. Since the XLR and 1/4" TRS connectors are wired in
parallel, an unbalanced connection at one connector will cause
the other connector to operate unbalanced, e.g. if a mono 1/4"
plug is inserted into the 1/4" jack, the corresponding XLR socket
will also operate unbalanced.
IMPORTANT NOTE: The output connectors can deliver an output
level of up to +34 dBu. Please ensure that all other equipment
can handle these levels to prevent possible damage.
