BUS
A bus is a signal route that
combines the signals of
multiple channels within
the mixer, and sends
the combined signal to
a common destination
output. The M-16DX has
four buses: MAIN, ALT,
AUX, and SOLO. (→p.8
“Glossary”)
Pre-fader/Post-fader
“Pre-fader” refers to the signal
before it passes through the
channel level control, and
“post-fader” refers to it the
signal immediately after the
channel level control. Since the
pre-fader signal is not affected
by pan or channel level, it is
often used when sending the
signal to a multi-track recorder
or to the stage monitors.
Bit depth/Sampling frequency
An analog audio wave is generally
represented by a continuous line
called a “waveform.” By measuring
its level at regular intervals of
time and recording these values
as a set of vertical gradations, we
get a shape that represents the
digital audio signal. The horizontal
interval is the sampling frequency
(expressed in Hz), and the vertical
intervals are determined by the
bit depth (the number of bits used
to quantize each sample). Using
higher sampling frequencies and
a greater number of bits will allow
the recorded digital signal to more
faithfully represent the original
waveform. Music CDs are recorded
as 16-bit 44.1 kHz digital audio.

circuitry, structure, and
materials of instruments or
audio equipment have on
a sound.

In order to bring out the full poten-
tial of an instrument, quality is
demanded of an audio mixer. It
must reproduce the full range of fre-
quencies from low to high without
faltering, and needs dynamic range
that can express everything from a
subtle whisper to a powerful roar.
The M-16DX/M-10DX use cutting-
edge digital technology to fulfill
these exacting requirements.
We have also included numerous
original ideas derived from Roland/
EDIROL’s years of experience in mak-
ing audio mixers. Experience the
enjoyment of mixing with the kind
of sparkling fidelity available only
with a digital mixer.
