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.

COSM technology

COSM (Composite Object

Sound Modeling) technology

This is proprietary Roland

modeling technology that

analyzes and simulates the

effect that the electrical

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.
