[ Cyclone Mono Input Channels ]
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 Cyclone 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 control over channels with phantom
power on.
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 engineers notices
interferences between microphones that can not be solved moving the
microphones. The LED gives an immediate control over channels with inverted
phase electronic circuits.
GAIN & LEVEL SET LED
The GAIN control gives you the chance to continuously adjust the preamplifier
gain for input signal. This control can be adjusted in 0/+60dB range for microphone
input and -25/+35dB for line input. The LEVEL SET LED will help the sound engineer to immediately detect the input level. In
this case the research of the fault will become much faster!
HIGH PASS switch & LED
This section allows the sound engineer to reduce the lower frequencies by engaging the switch This control is very useful
when you detect hum or rumble or you want to cut unwanted low frequency sounds picked-up by microphones. The LED
shows if the HIGH PASS section is active or not.
