Separate inputs and outputs
Each Frontliner module is equipped with its own input and output stage. An obvious purpose
is to route the signal from any output, e. g. right after the preamp to store the pure recording
signal. Further applications such as using single or grouped modules separately or inserting
external processors are depicted on pages 9 and 10. Inserts can be determined before each
processing module input.
Preamplifier: MIC IN
You can connect any kind of microphone to the MIC IN socket (dynamic, condenser, tube and
ribbon microphones). 48 volts phantom power, which is required for some microphones, can
be activated with the 48V switches on the front or rear panel. Please read the important notes
in chapter “48V” on page 15. The microphone input can also be equipped with an optional
transformer (refer to page 27, “Information on I/O transformers”).
Preamplifier: LINE IN
Use the balanced LINE IN socket for high-level signals with impedances lower than 1 kOhm,
e. g. D/A converters, synthesizers or samplers. We recommend connection to a patchbay for
easier access.
The maximum input level of the LINE IN is +22 dBu.
High impedance sources (above 1 kOhm), such as e-guitars and basses, acoustic guitars with
pick ups and so on, must be connected to the instrument input (see pages 16 and 17).
IMPORTANT: The line input is deactivated if the instrument input is in use.
Preamplifier: OUT
The electronically balanced, analog preamplifier output provides the preamplified signal
prior to any processing. If you determine an insert between preamplifier and de-esser, the
preamplifier output serves as insert send.
De-Esser: IN and OUT
The analog de-esser input and output sockets are electronically balanced.
Normally the de-esser input signal is the internal preamplifier signal. If you are using the
de-esser module separately as single module, you connect the source and receiving units to
the de-esser inputs and outputs. If you are using the de-esser module as part of a group of
modules, you connect the source and receiving units to the group inputs and outputs. If you
determine an insert between preamplifier and de-esser, the de-esser input serves as insert
return.
