Alto Typhoon User Manual

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 control over channels with phantom
power on.
GAIN
The GAIN control gives you the chance to
continuously adjust the pre-amplifier gain
for input signal. This control can be adjust-
ed in 0/+60dB range for microphone input/
line input.
HIGH PASS LED
A very useful LED shows if the HIGH PASS
section for the MONO input is active or
not.
INPUT SELECT LED
This LED is lit when you use a mono signal,
the INPUT SELECT switch is pressed.
PHASE switch & LED
CLIP LED
At LTO we're very careful about the feedback
we continuously receive by our customers and
the demands of pro users. For this reason we in-
cluded a preamp CLIP LED, allowing the sound
engineer to detect the clip incurring at the beginn-
ing of the audio path. The preamp CLIP LED turns
on when the input level reaches 6dB before clip-
ping. If the clipping has been generated by other
channel controls (e.g. an excessive boost by EQ.)
the sound engineer will see the preamp CLIP LED
not lighted, while the fader clip LED will be lighted.
In this case the research of a wrong level setting
will become much easier.
HIGH PASS switch
This section will allow the sound engineer to re-
duce the lower frequencies of MONO INPUT 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.
STEREO IN GAIN
The GAIN control gives you the chance to contin-
uously adjust the amplifier gain for LEFT (MONO)
& RIGHT inputs. This control can be adjusted in
-20/+20dB range input.
INPUT SELECT switch
Pressing this switch you'll select the mono input
source for this channel, while releasing this switch
you'll use the stereo signal.

[ Typhoon Stereo Input Channels ]
The Typhoon preamp section is fully featured with all the useful controls to manage the sound source. There are two
different preamp input path for mono or stereo signals, the latter features just GAIN while the mono preamp input is
regularly featured like any other mono input. In this way the sound engineer can use, for example, the stereo keyboard
outputs in the same channel of the entertainer voice, if both signals are not required at the same time and each source
will has its own level control.
This switch allows the user to invert by 180 the
signal. This switch is very useful in a lot of circum-
stances, in particular when several microphones
are very close (e.g. drum kit, brass, choirs etc.)
and the sound engineer notices interferences be-
tween microphones that can't be by solved moving
the microphones. The LED gives an immediate
control over channels with inverted phase electronic
circuits.
