■
Channel section
Use these controls to adjust factors such as the
equalization, (frequency response), volume,
effect and monitor output level for the input sig-
nal to each channel.
1
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. Response is flat
when the knobs are in the
▼
position. Rotating it
toward the right will boost the corresponding fre-
quency band, and rotating it 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: 10 kHz
±
15 dB shelving type
MID: 2.5 kHz
±
15 dB peaking type
LOW: 100 Hz
±
15 dB shelving type
2
Monitor controls (MONI)
For each channel, this controls the amount of sig-
nal that is sent to the MONI bus.
The signal of the MONI bus is sent to the speak-
ers connected to the MONITOR A/B jacks and to
the MONITOR jacks (input/output panel
6
).
3
Effect control (EFFECT)
For each channel, this controls the amount of sig-
nal that is sent to the EFFECT bus.
The signal of the EFFECT bus passes through the
EFFECT section and the built-in digital effect,
and is sent to the external effect device connected
to the EFFECT OUT jacks (input/output panel
3
).
4
PAN control (BAL/PAN control for CH7/8)
This knob adjusts the stereo image (L/R) for each
channel. Adjust for equal volume on left and
right with a sound source input to the CH7 and 8
LINE connectors (L/R).
5
Level control (LEVEL)
This adjusts the output level for each channel.
6
Pad switch (PAD) (1–6 only)
This switch attenuates the input signal by 30 dB.
When connecting a line level device to channels
1–6, or if the mic input is distorted, turn this
switch on (the pressed-in position).

1 Channel input jacks (Hi-Z, Lo-Z) 1–6
These are the input jacks for channels 1–6. By
using the PAD switches (control panel 6) you
can connect any of the jacks to a wide range of
sources from mics to line level devices (synthesiz-
ers or rhythm boxes etc.). The Lo-Z jacks can
provide +48 V phantom power, allowing you to
use condenser microphones.
Both Hi-Z and Lo-Z are balanced, and are com-
patible with microphones of output impedance
50–600Ω or line level devices of 600Ω. The nom-
inal input level is from –40 dB to –10 dB for the
Hi-Z jacks, and from –50 dB to –20 dB for the
Lo-Z jacks.
Pin connections for the Hi-Z and Lo-Z jacks are
as follows.
2 Channel input jacks (MIC/LINE) 7–8
These are the input jacks for channels 7–8.
Connect microphones to the MIC jacks. Connect
line-level devices, such as synthesizers to LINE L
(MONO)/R jacks if the devices are stereo sound
sources. Use the LINE L (MONO) jack if the
devices are monaural sound sources.
The MIC jacks are balanced, and are compatible
with microphones of output impedance 50–
600Ω. The LINE jacks are unbalanced, and are
compatible with line level devices of 600Ω output
impedance. Nominal input level is –50 dB for the
MIC jacks and –20 dB for the LINE jacks.
3 Effect output jack (EFFECT OUT)
The input of an external effect such as a delay or
echo can be connected to this jack. The signal
adjusted by the EFFECT control of each channel
will be sent to the EFFECT bus, its level adjusted
by the EFFECT OUT control, and output from
this jack.
The nominal output level and impedance are
+4 dB/10 kΩ.
4 Foot switch jack (FOOT SW)
You can connect a Yamaha FC5 foot switch (sold
separately) to this jack and use it to turn the
built-in digital effect on and off. The Digital

5 AUX IN/TAPE IN jacks
These are input jacks that allow the signal from
an external device to be added to the MAIN out-
put.
• AUX IN jacks: Connect these jacks to the
output jacks of an external effects processor.
If the effects processor has a stereo output,
connect it to the AUX IN L (MONO) and R
jacks. If it has monaural output, use the AUX
IN L (MONO) jack. Signal input to these
jacks is sent to the ST bus.
• TAPE IN jacks: Use these jacks to connect a
stereo device, such as a cassette player or a
CD player. The signals input to these jacks is
sent to the ST bus.
The nominal input level and impedance are –10 dB/
600Ω for the AUX IN jack, and –10 dBV/600Ω
for the TAPE IN jacks.
6 REC OUT/MONITOR/MAIN (STEREO)
jacks
These are output jacks which send line level sig-
nals from the EMX860ST to external devices. A
stereo recording device such as a cassette recorder
or MD recorder can be connected to the REC
OUT jacks, and a playback device such a power
amp can be connected to the MONITOR and
MAIN (STEREO) jacks. The signals sent from
each jack are as follows.
• REC OUT jacks: The ST bus signal before it
has passed through the MASTER control
and graphic equalizer
• MONITOR jack: The MONI bus signal
which has passed through the Monitor MAS-
TER control and graphic equalizer
• MAIN (STEREO) jack: The ST bus signal
which has passed through the Main MAS-
TER control and graphic equalizer
The nominal output level and impedance are
–10 dBV/10 kΩ for the REC OUT jacks, and
+4 dB/10 kΩ for the MONITOR/MAIN (STE-
REO) jacks.

1 SPEAKERS MONITOR jacks
Connect monitoring speakers to these jacks.
MONI bus signals adjusted at the MONITOR
section are output from these jacks. The SPEAK-
ERS MONITOR A and B jacks are internally con-
nected in parallel, and output the same signals.
You can connect speakers with an impedance of
4–8Ω to either or both the A or B jacks. You can
connect speakers with an impedance of 8–16Ω to
both pairs.
2 SPEAKERS L/R/L+R BRIDGE jacks
Use these jacks to connect the main speakers.
These jacks output ST bus signals that are
adjusted at the MASTER section. The speaker
connection varies depending on the setting of the
stereo/bridge select switch.
■ When the Stereo/Bridge select
switch is set to STEREO (2-chan-
nel connection)
L/R channel signals are routed from the ST bus to
the SPEAKERS L/R jacks. The SPEAKERS L A/B
jacks are internally wired in parallel and output
the same signals. You can connect a pair of speak-
ers with an impedance of 4–8Ω to either or both
the A or B pair of the SPEAKER L/R jacks (total
of two speakers). You can connect two pairs of
speakers with an impedance of 8–16Ω to both A
and B pairs or the SPEAKER L/R jacks (total of
four speakers).
This connection provides a maximum output of
200 W + 200 W.
■ When the Stereo/Bridge select
switch is set to L+R BRIDGE
(BRIDGE connection)
L/R channel signals are mixed in the ST bus and
routed to the SPEAKERS L+R BRIDGE jack as a
monaural signal. You can connect only one

When connecting various devices, make sure the cables and plugs have the correct rating.
Be sure to use cables designed for the purpose when you connect speakers to speaker jacks.
■ Connecting monitoring speakers
You can connect one or two speakers to the SPEAKERS MONITOR jacks. Speaker impedance varies with the
number of speakers that are connected. Be sure to maintain speaker impedance at the specified value or
higher. Refer to the figure below.
■ Connecting main speakers
If you select the two-channel connection, connect the speakers to the SPEAKERS L/R jacks. If you select the
BRIDGE connection, connect the speakers to the SPEAKERS L+R BRIDGE jack. Depending on the number
of connected speakers and the type of connection, speaker impedance requirements vary. Be sure to maintain
speaker impedance at the specified value or higher. Refer to the figure below.

Basic Operation 15
EMX860ST—Owner’s Manual
Basic Operation
Connecting microphones
and instruments
1 Before connecting mics or instruments,
make sure that the power of all equip-
ment (where applicable) is turned off.
Also make sure that the level controls of
each channel of the EMX860ST and the
MASTER control of the MAIN section are
turned down.
2 Connect cables to your mics and instru-
ments, and insert the other end of the
cable firmly into the appropriate Lo-Z/Hi-
Z jack (channels 1–6) or the MIC/LINE
jack (channels 7–8).
3 Turn the power on in the order of periph-
eral devices ➞ EMX860ST.
4 Set the MAIN section MASTER control to
the √√
√√
position.
Adjusts the stereo image of each channel using
the PAN controls. (Adjust the balance between
the left and right volume levels of the sound
sources connected to the LINE connectors L/R
for channels 7 and 8 using the BAL/PAN con-
trols.)
5 While speaking into the mic (while play-
ing the instrument), adjust the channel
LEVEL control so that the 0 LED of the
MAIN section peak level meter lights
occasionally.
6 If you wish to adjust the tone of each
channel, rotate the equalizer controls as
desired.
7 Use the MAIN section graphic equalizer
and MASTER control to adjust the overall
volume and tone.
Sending an independent
mix to the monitor speakers
1 Set the MONITOR section MASTER con-
trol to the √√
√√
position.
2 Adjust the MONI control to increase the
level of the channel you want to hear
from the monitor speaker, and also adjust
so that the peak level meter 0 LED of the
monitor section lights up occasionally.
3 Use the graphic equalizers and MASTER
controls of the MAIN/MONITOR sections
to adjust the overall volume and tone.
Using the digital effect
The EMX860ST has a built-in digital effect,
allowing reverberation or ambiance to be added
to vocals or instrumental sounds.
1 Connect a mic or instrument to the
desired channels, and adjust the volume
and tone.
2 Press the DIGITAL EFFECT ON switch of
the DIGITAL EFFECT section.
3 Use the effect select switches of the DIGI-
TAL EFFECT section to select the effect
type.
VOCAL ...... Reverb appropriate for vocals.
L. HALL...... Reverb typical of a large hall.
S. HALL...... Reverb typical of a small hall.
4 Raise the EFFECT control of the channels
to which you wish to apply the digital
effect.
5 Use the MAIN/MONITOR section EFFECT
RTN control to adjust the level of the
sound processed by the effect.
Note: When connecting a line level device to
channels 1–6, turn on the PAD switch.
You cannot use a channel’s Lo-Z and Hi-Z
jacks, and MIC and LINE jacks at the same
time.
Note: When turning the power off, reverse this
sequence.
Note: The MONI controls are not affected by
the level settings of each channel. This allows
you to create a mix that is independent of the
MAIN section.
Note: If the effect sound is distorted even if the
EFFECT RTN is turned all the way down, lower
the EFFECT controls of each channel.

Note: Set the power amp select switch of the
POWER AMP section to the “MAIN MONI-
TOR” position.
If you are using an external effect, we recom-
mend that you turn down the EFFECT RTN
controls of the MAIN and MONITOR sections.
If the external effect has a stereo output, it is
possible to connect its output jacks to the LINE
jacks of channels 5–6. However in this case, be
sure that the EFFECT controls are turned all the
way down for the channels into which the effect
sound is being input. If the EFFECT controls
are raised, feedback will occur, and your speak-
ers may be damaged.

Problem Cause Action
Sound is no
longer out-
put from the
speakers.
The POWER
indicator is
dark.
The load on this device was too great, and
the protection circuit for the internal
transformer
has operated. Possible rea-
sons for the excessive load are an exces-
sive input to the device, or inappropriate
ventilation.
Please wait. When the device cools off, normal opera-
tion will resume automatically. However, please
check the following two points to prevent the problem
from recurring.
If the input to this device is greater than the nominal
level, lower the input to the nominal level. If the
device is not ventilated sufficiently, refer to the cau-
tions given at the beginning of this manual and take
appropriate measures to insure adequate ventilation.
The POWER
indicator is lit.
The load on the amplifier of this device
was too great, and
the protection circuit
for the amplifier
has operated. Possible
reasons for the excessive load are an
excessive level setting in the channel con-
trol section or main section, insufficient
ventilation, or insufficient load imped-
ance of the connected speakers.
Please wait. When the device cools off, normal opera-
tion will resume automatically. However, please
check the following three points to prevent the prob-
lem from recurring.
If the level setting is excessive, lower it to the nomi-
nal level. You can refer to the peak level indicators of
the main section when doing so.
If the device is not ventilated sufficiently, refer to the
cautions given at the beginning of this manual and
take appropriate measures to insure adequate ventila-
tion.
If the load impedance (including a short) is too low,
refer to the chapter on connections (page 13) and
change the connections so that the impedance is cor-
rect.
Other
Connections between devices have come
loose.
Inspect the connections, and correct any faulty con-
nections.
