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.

POWER amp section

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

).

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.
