Compressor: IN and OUT
The analog compressor input and output sockets are electronically balanced.
Normally the compressor input signal is the internal de-esser signal (or the EQ signal if EQ
PRE COMP. is activated). If you are using the compressor module separately as single module,
you connect the source and receiving units to the compressor inputs and outputs. If you are
using the compressor module separately as part of a module group, you connect the source and
receiving units to the group inputs and outputs. If you determine an insert between de-esser
and compressor, the de-esser output is the insert send and the compressor input is the insert
return.
Equalizer: IN and OUT
The analog equalizer/tube saturation input and output sockets are electronically balanced.
Normally the EQ input signal is the internal compressor signal (or the de-esser signal if EQ
PRE COMP. is activated). If you are using the equalizer module separately as single module, you
connect the source and receiving units to the equalizer inputs and outputs. If you are using the
equalizer module separately as part of a module group, you connect the source and receiving
units to the group inputs and outputs. If you determine an insert between compressor and
equalizer, the compressor output is the insert send and the equalizer input is the insert return.
MAIN OUTPUTS: OUT 1 and OUT 2
The output signal of the channel strip is supplied by the electronically balanced, analog
outputs OUT 1 and OUT 2. The splitted outputs allow to feed recording and monitoring devices
simultaneously, or, in a live application, monitoring and P. A. paths. Each output is driven by its
own stage to exclude mutual influences. OUT 1 can optionally be equipped with a transformer
(refer to page 27, “Information on I/O transformers”).
If you have excluded all three processing modules from the channel strip as a group, the
group’s output signal is supplied by the MAIN OUTPUTS. In this case, the preamplifier output
signal is only present at the preamp’s output. In all other cases the final output signal of the
channel strip is always present at the MAIN OUTPUTS.
AD Input 2
The Frontliner is a mono channel strip, but the optional A/D converter card is a dual-channel
device. Therefore a second (external) signal can be converted with the converter card, if it is
connected to the AD INPUT 2. If no signal is connected to the A/D INPUT 2, the output signal of
the Frontliner is routed to both converter channels. The maximum input level for the converter
is +12dBu (=0 dBFS).
Power connection and fuses
Connect the power cord to the rear MAINS INPUT socket. Transformer, power cord and case
connection conform to VDE, UL and CSA requirements.
The Frontliner’s power supply houses two fuses, one for the neutral wire and one for the phase
conductor. The fuses are accessible from outside and placed right behind the flap below the
socket. Fuse ratings are 315 mA slow blow (230 volts) or 630 mA slow blow (115 volts).
