Settings for HK AUDIO VX 2400 amps:
Gain VX 2400: + 35 dBu
Max Output ( Firnet): + 6 dBu
The FIRNET’s limiter cannot effectively attenuate
signals when set to other dBu levels, so connected
speakers may be damaged or destroyed.
7.4.5.5 Muting Outputs
The SPEAKER, SCENE, LEVEL, DELAY/PHASE and
ADMIN keys serve the second purpose of muting
outputs. The label above each key tells you its
mute function. To mute outputs, press and hold
the MUTE/HOLD key and press the key of the
output you wish to mute (key A to D for Output
A to Output D). The Lim/Mute LED in the given
output’s LED chain lights up red to indicate the
output is muted. Follow the same procedure to
enable the output.
7.5 Firmware
The FIRNET controller ships with the current
fi rmware. LIPAN software lets you update the
device with future fi rmware versions. See chapter 4
LIPAN PC Software, to learn more about fi rmware
updates.
