equilateral triangle, is intended to alert you to the
presence of uninsulated "dangerous voltage” within
the product's enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle is
intended to alert you to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.

the power of all units OFF and turn the MJ100
master volume all the way down.
Do Not Open the Unit
This product contains no user-servicable parts.
Refer all maintenance to qualified YAMAHA ser-
vice personnel. Opening the unit and/or tampering
with the internal circuitry will void the warranty.
Cleaning
Never use solvents such as benzine or thinner to
clean the unit, and do not use aerosol-type sprays
nearby. Wipe the unit clean with a soft, dry cloth.
Electrical Storms
In the event of an electrical storm (lightning)
nearby, unplug the power cable from the AC power
source.

The AUX control adjusts the signal sent from the
INST inputs to the internal delay circuit or the rear
panel AUX SEND. The L and R signals will be
mixed. You cannot send only L or only R. When
an effects device is connected between AUX SEND
and AUX RETURN, the front panel AUX control will
regulate the depth of the effect.
The level will increase as you rotate AUX to the

INPUT
SELECT
switches
These switches select the sources connected to the
rear panel SOURCE 1 and SOURCE 2 inputs. Press
the switch to select the corresponding source.
D dë SOURCE 1, 2 faders
These adjust the level of the input sources selected
by the Input Select switches. A single fader controls
both L and R. Use these faders to balance the
SOURCE 1 and 2 inputs with the other input chan-
nels.
@ CROSS FADER
This fader adjusts the balance between SOURCE
1 and SOURCE 2, as follows.
e As the CROSS FADER is moved to the left,
SOURCE 1 becomes louder and SOURCE 2 be-
comes softer.
@ When the CROSS FADER is in the center posi-
tion, SOURCE 1 and 2 are the same level.
e As the CROSS FADER is moved to the right,
SOURCE 1 becomes softer and SOURCE 2 be-
comes louder.
This is a graphic equalizer with center frequencies
at 100Hz, 400Hz, 1kHz, 3kHz and 8kHz, with
+/—12dB of control over each band. Moving a
slider in the plus (+) direction will emphasize that
frequency range. Moving a slider in the minus (—)
direction will de-emphasize that frequency range.
When the slider is at 0, the response is flat. Adjust
equalizer settings to suit the room or speaker
system you are using. The equalized signal is sent
only from the MASTER OUT L, R jacks. Each slider
of the equalizer affects both channels L and R in
the same way.
@ MASTER fader
The MASTER fader regulates the level output from
the rear panel MASTER OUT L, R jacks. It controls
the final volume (channels L and R together) of the
mixed input sources. Adjust the MASTER fader
level according to the VU meters (4D, D).
®
;
(20)
Output
VU
meters
These meters indicate the level of the signal output
from the rear panel MASTER OUT L and R jacks.
The levels will depend on the MASTER fader set-
ting. Adjust the MASTER fader @ so that the
loudest signal makes the meters indicate 0dB.
A) LINE OUT fader
The LINE OUT fader regulates the level output from
the rear panel LINE OUT L, R jacks. It controls the
final volume (channels L and R together) of the
mixed input sources sent from the LINE OUT jacks.
6) DELAY TIME select switch
The MJ100 has a built-in delay unit. When the rear .
panel AUX RETURN jacks are not being used, a
Long, Mid or Short delay can be selected.
@ REGENERATION control
When the rear panel AUX RETURN jacks are not
being used, the REGENERATION control regulates
the amount of signal sent to the built-in delay unit.
Use REGENERATION together with @ RETURN
to adjust the amount of delay effect. When the
RETURN control is at 0, there will beno delay effect.
The built-in delay unit can be used only by the MIC
and INST inputs.
Note) fan effects device is connected to the rear
panel AUX RETURN inputs, the built-in
delay unit will not operate, and @ and ®
will have no effect.

(24) SEND control
The SEND control regulates the level of the signal
output from the rear panel AUX SEND jack. When
using an external effects unit, this control regulates
the level of the signal sent to the external effects
unit. Only the MIC and INST inputs can send a
signal through the SEND control to the rear panel
AUX SEND jack.
(2) RETURN control
The RETURN control regulates the level of the
signal received from the rear panel AUX RETURN
inputs. When an external effects device is con-
nected, this control regulates the level of the signal
received from the external effects unit. If nothing
is connected to the AUX RETURN jacks, this control
regulates the level of the signal from the built-in
delay unit.
@ MONITOR SELECT switches
These switches select the signal to be monitored
in the headphones. The monitor signal is selected
as follows.
e SOURCE 1 & 2... The Selected Source 1 mixed
(L FR) signal input the left channel, and Selected
Source 2 mixed (L+R) signal input to the right
channel. All signals are before the source fader.
e MIC ... The MIC signal input after the mic amp
but before the MIC fader. l
O INST ... The INST signal input before the INST
fader.
e MASTER OUT ... The mixed signal output from
the MASTER OUT jacks. Input signals are mon-
itored before the faders, and output signals are
monitored after the faders.
@ PHONES LEVEL control
The MONITOR LEVEL control regulates the level
of the headphone monitor signal. The headphone
will monitor the signal selected by the MONITOR
SELECT switches.
Q) PHONES jack
Connect a pair of stereo headphones to this jack
to monitor the signal selected by (26) and regulated
by @.
@) POWER indicator
When the rear panel power switch is turned on, this
indicator will light.
