We perfectly know the importance of the preamp section, a good preamp section will allow the sound engineer to work
with maximum dynamics, an exceptional signal-to-noise ratio... then to be able to use EQ, external dynamic controls
and other ancillary equipment to shape its own sound!
The Typhoon preamp section features all the useful controls to accurately manage the sound source in the most ver-
satile way.
PHANTOM POWER switch & LED
The switch must be engaged when
you're using a condenser microphone
or a direct box that can be powered
by phantom power, instead of batteries.
The LED gives the user a visual con-
trol over channels with phantom power
on.
GAIN
HIGH PASS LED
A very useful LED shows if the HIGH
PASS section is active or not.
PHASE switch & LED
This switch allows the user to invert by 180
the signal. This switch is very useful in a lot
of circumstances, in particular when several
microphones are very close (e.g. drum kit,
brasses, chorus, etc.) and the sound engi-
neers notices interferences between micro-
phones that can not be solved moving the
microphones. The LED gives an immediate
control over channels with inverted phase
electronic circuits.
CLIP LED
At LTO we're very careful about the feed-
back we continuously receive by our cus-
tomers and the demands of pro users. For
this reason we included a preamp CLIP LED,
allowing the sound engineer to detect the
clip incurring at the beginning of the audio
path. The preamp CLIP LED turns on when
the input level reaches 6dB before clipping.
If the clipping has been generated by other
channel controls (e.g. an excessive boost
by EQ.) the sound engineer will see the pre-
amp CLIP LED not lighted, while the fader
clip LED will be lighted. In this case the re-
search of the fault will become much faster!
HIGH PASS switch
This section allow the sound engineer to re-
duce the lower frequencies by engaging the
switch and selecting the turnover frequency
in 40Hz/400Hz range. This control is very
useful when you detect hum or rumble or
you want to cut unwanted low frequency
sounds picked-up by microphones.

[ Typhoon Mono Input Channels ]
The GAIN control gives you the chance
to continuously adjust the pre-amplifier
gain for input signal. This control can be
adjusted in 0/+60dB range for microphone
input and -25/+35dB for line input.
