the Roland
SN-550
Digital
Noise
Eliminator.
The
SN-550
includes
both
noise and hum
canceling
units that can effectively
reduce
noise during
live performances
and studio
recordings.
To make
the best
use
of this device, please

carefully.
FEATURES
@ The SN-550 includes both noise and hum canceling units which
can
reduce
the noise
generated
by musical
instruments
or
variable lighting systems, the hum caused by power supplics or
picked up by microphones and guitars, the tape hiss of analog
recording equipment etc.
It can therefore be effectively used in
live performance or studio recording situations.
@Jn the noise canceling unit, the input signal is divided into five
bands.
This makes it possible to reduce the noise in a specific
frequency range of cach band, therefore effectively removing
the noise from the input signal.
@The
hum canceling unit removes
hum with minimal
tonal
alteration.
It effectively removes the hum caused by power
supply
lines
with
an
automatic
power
supply
frequency
detecting system.
@Owing
to
the
latest
signal
processing
technology,
fine
adjustments can be made quickly and easily.
@The SN-550 features a monitoring function that allows you to
monitor the noise and hum canceling operations.
@An internal level-controfling system is used to adjust the signal
without affecting the input or output level.
@The SN-550 has two completely independent channels for signal
processing and therefore can be connected
to a stereo sound
source or two mono sound sources, with different settings for
each source.
@Both 1/4 inch phone and XLR balanced connectors are provided
for input and output so that the SN-550 can be used with various
types of devices.
@Analog
circuits are constructed
with discrete systems
at all
stages to ensure high quality sound.
@The
SN-550
features
a bypass (on/off) switch.
When
this
switch is tumed on, the input signal will be output without
passing through the intemal circuits.
