The Owner’s Manual Revisions
Thank you for purchasing the Yamaha EMX5000-20/EMX5000-12 Powered Mixer. Parts of the EMX5000-20, EMX5000-12 owner’s
manual have been revised. Please refer to the following revisions rather than the corresponding sections of the original owner’s
manual.

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.

^
Level Meter
This LED display shows the
level of signals received at the
ST OUT jack (input/output
panel
0
).

SPEAKERS (speaker output) jacks
These jacks are used to connect speakers.
Jacks 1 are Speakon-type connectors. Use only Neutrik
NL4FC plugs for connecting Speakon connectors.
Jacks 2 are 1/4”phone jacks. The setting of the control
panel power amp select switch
Y
will determine the sig-
nal that is output to these jacks, and the number and
appropriate impedance of the speakers that can be con-
nected.
P.33
Block/Level Diagram
Power Amplifier output section level diagram (bottom right)
These plots show the nominal output and maximum output
levels of signals received at the SPEAKERS jacks. If the output
level is +4dB (Level Meter “0”), the internal power amplifier
will deliver 100W into a 4
Ω
load. If the output level is +11dB
(LIMITER indicator lights), the internal amplifier will deliver
a maximum of 500W into 4
Ω
.
E
Caution:
If the LIMITER indicator flashes continuous-
ly, the internal power amplifier section is being exces-
sively 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.
Note:
The SPEAKERS 1 & 2 jacks (rear panel
3
) out-
put the signals received at the ST OUT jack via the inter-
nal power amplifier. Check the output signal level via
the LIMITER indicator (
X
). The LIMITER indicator
will light before the Level Meter “8” or “PEAK” LED
light.
