LIMITER indicator

If the output level of signals received at the SPEAKERS
jacks (output of the internal power amplifier) reaches
maximum, the indicator will light.

Caution: If the LIMITER indicator flashes continuous-

ly, the internal power amplifier section is being exces­sively overloaded and may malfunction. Reduce the
output level at the ST OUT fader (K) below the level
that the indicator flashes only briefly on the highest
transient peaks.

PRECAUTIONS FOR OPERATION – FOR CORRECT OPERATION –

Connector pin assignments

• XLR-type connectors are wired as follows: pin 1: ground, pin 2:
hot (+), and pin 3: cold (–).

• Insert TRS phone jacks are wired as follows: sleeve: ground, tip:
send, and ring: return.

Replacing abrasive parts

• The performance of components with moving contacts, such
switches, rotary controls, faders, and connectors, deteriorates
over time. The rate of deterioration depends on the operating
environment and is unavoidable. Consult your dealer about
replacing defective components.

Influence on cell phone usage

• Using a cell phone (mobile telephone) near this unit may induce
noise. If noise occurs, use the telephone away from the unit.

Volume level setting

• Do not set all equalizer controls and faders to maximum.
Doing so may cause oscillation depending on the condition of
the connected unit and speakers, and may damage the speakers.

Interference with other electronic devices

• The digital circuits of this unit may induce a slight noise into
nearby radios and TVs. If noise occurs, relocate the affected
equipment.

EMX5000-20/EMX5000-12—Owner’s Manual

Introduction

Thank you for purchasing the Yamaha
In order to take full advantage of the
trouble-free performance, please read this owner’s manual carefully, and keep it
in a safe place for future reference.

Features

• The EMX5000-20/EMX5000-12 provides versatile
inputs, such as two stereo input channels and two ste­reo sub inputs, as well as 16 (EMX5000-20), 8
(EMX5000-12) monaural input channels compatible
with mic/line signals. The mixer also has ample power,
with a maximum output of 500 W+500 W (1000 W
with bridge connection), and is suitable for a wide
range of applications from installed systems to small­scale PA systems.

• A two-channel power amp is built-in. The signals out­put to speakers can be selected as stereo (ST L-R),
AUX+monaural (AUX 1- MONO), two AUX (AUX1­AUX2) or monaural (bridge connection).

• In addition to the speaker output jacks, two stereo
output channels for line-level signals, two AUX output
channels, two effect outputs, and one monaural out­put are provided. You can easily expand the system by
adding a power amplifier or powered speakers.

• The EMX5000-20/EMX5000-12 also has a PHONES
jack, which is very useful for checking the sound. You
can monitor only a specific channel or bus signal
through the headphones.

• Each amp contains a limiter circuit to prevent distor­tion due to excessive input levels.

• A maximum output select switch lets you switch the
maximum output of the amp between three levels.
This lets you adjust the maximum output of the inter­nal power amp as appropriate for the size of the room
or the input capacity of the speakers.

• Two multi-effect units are built-in, each providing six­teen types of effect equivalent in quality to the
acclaimed Yamaha SPX series of multi-effect units.
The effects can be used to add reverb or ambience to
vocals or instruments. The sixteen types (provided by
each of the two effect units) include TAP DELAY,
which lets you easily adjust the delay time.

• The EMX5000-20/EMX5000-12 has implemented
“EEEngine”, Yamaha’s epochal amp drive technology
to create an unrivaled high-efficiency drive.
The EEEngine’s energy-saver/low-heat-generation
design has reduced power consumption to 50% or
less, and reduced heat generation to 35% or less (in
field applications, compared to Yamaha’s previous
models), and has lead to a reduction in energy cost
and to less-restrictive installation requirements related
to heat generation.

(High pass filter) switch

This is an on/off switch for the high-pass filter.
The high-pass filter is on when the switch is
pressed inward, and the frequency region below
80 Hz will be attenuated at 18 dB/octave.

Equalizer controls (HIGH, MID, LOW)

This is a 3-band equalizer that adjusts the high
frequency range, mid frequency range, and low
frequency range of each channel.

When the HIGH and LOW knobs are in the “▼”
position, the high and low ranges will have a flat
response. Turning a knob toward the right will
boost the corresponding frequency range, and
turning it toward the left will cut it.

For the mid range, use the upper MID knob to
specify the center frequency of the range, and use
the lower knob to set the amount of boost or cut
that will occur. The frequency response is flat
when the lower knob is set to the “▼” position.
Turning the lower knob toward the right will
boost the corresponding frequency range, and
turning the knob toward the left will cut it.

The base frequency (or center frequency), range
of boost or cut, and equalizer type of each band
are as follows:

HIGH: 10kHz, ±15 dB, shelving type
MID: 250Hz–5kHz, ±15 dB, peaking type
LOW: 100Hz, ±15 dB, shelving type
