Rear panel/connections

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.
