Warnings

• Do not allow water to enter this unit or allow the unit to become wet. Fire or electrical shock
may result.

• Connect this unit’s power cord only to an AC outlet of the type stated in this Owner's Manual
or as marked on the unit. Failure to do so is a fire and electrical shock hazard.

• Do not scratch, bend, twist, pull, or heat the power cord. A damaged power cord is a fire and
electrical shock hazard.

• Do not place heavy objects, including this unit, on top of the power cord. A damaged power
cord is a fire and electrical shock hazard. In particular, be careful not to place heavy objects on
a power cord covered by a carpet.

3

• If you notice any abnormality, such as smoke, odor, or noise, or if a foreign object or liquid
gets inside the unit, turn it off immediately. Remove the power cord from the AC outlet.
Consult your dealer for repair. Using the unit in this condition is a fire and electrical shock
hazard.

• Should this unit be dropped or the cabinet be damaged, turn the power switch off, remove the
power plug from the AC outlet, and contact your dealer. If you continue using the unit
without heeding this instruction, fire or electrical shock may result.

• If the power cord is damaged (i.e., cut or a bare wire is exposed), ask your dealer for a
replacement. Using the unit with a damaged power cord is a fire and electrical shock hazard.

• Do not remove the unit's cover. You could receive an electrical shock. If you think internal
inspection, maintenance, or repair is necessary, contact your dealer.

• Do not modify the unit. Doing so is a fire and electrical shock hazard.

Cautions

• Allow enough free space around the unit for normal ventilation. This should be: 20 cm at the
sides, 40 cm behind, and 40 cm above.
These distances should also be adopted when rack-mounting the unit. For normal ventilation
during use, remove the rear of the rack or open a ventilation hole.
If the airflow is not adequate, the unit will heat up inside and may cause a fire.

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-chan­nel 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

Basic Operation

Basic Operation 15

Connecting microphones and instruments

1 Before connecting mics or instruments,

make sure that the power of all equip­ment (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/Hi­Z jack (channels 1–6) or the MIC/LINE
jack (channels 7–8).

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.

3 Turn the power on in the order of periph-

eral devices ➞ EMX860ST.

Note: When turning the power off, reverse this
sequence.

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 con­trols.)

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.

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.

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: 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 MONI­TOR” position.

If you are using an external effect, we recom­mend 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 speak­ers may be damaged.

Using an external effect

1 Set the EFFECT section EFFECT OUT con-

trol to the √√√√ position.

2 Raise the EFFECT controls for the channels

to which you want the external effect to
be applied.

3 Adjust the input level of the external

effect so that the sound is not distorted at
the input of the external effect.
