NOTE: This equipment has been tested and found to com-
ply with the limits for a Class A digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to pro-
vide reasonable protection against harmful interference
when the equipment is operated in a commercial environ-
ment. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications.
Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be
required to correct the interference at his own expense.
FCC Caution: To assure continued compliance, (example -
use only shielded interface cables when connecting to com-
puter or peripheral devices). Any changes or modifications
not expressly approved by the party responsible for compli-
ance could void the users authority to operate this equip-
ment.
For U.S.A
WARNING:
To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK).

CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
The lightning flash with arrowhead symbol,
within an equilateral triangle, is intended to
alert the user to the presence of uninsulated
dangerous voltage within the products
enclosure that may be of sufficient magni-
tude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and mainte-
nance (servicing) instructions in the litera-
ture accompanying the appliance.
Power disconnection. Unit with or without
ON-OFF switches have power supplied to
the unit whenever the power cord is inserted
into the power source; however, the unit is
operational only when the ON-OFF switch is
in the ON position. The power cord is the
main power disconnect for all units.

This audio mixer has four mono input lines, four stereo input lines, one mono/stereo input line and three output lines.
FEATURES
●Three modes applicable to different amplification systems
DIP switches at the rear panel support the following amplification systems:
•Mode 1: One-circuit amplification (stereo: 1 and mono: 1)
•Mode 2: Two-circuit amplification (stereo: 1 or mono: 1)
•Mode 3: Three-zone amplification (stereo: 1 and mono :2)
●Integrated level control of microphone sounds or BGM
The mono or stereo output level is adjustable with one knob: the MONO OUT or STEREO OUT knob.
●Customizable amplification systems
•The SUB OUTPUT connector can be assigned to a desired input line from among the STEREO INPUT jack 1 to 4, the con-
nectors MONO INPUT 1 to 4, and the MULTI IN STEREO/MONO jack. Refer to p. 18 Output Line Setting for SUB OUTPUT
for details.
•The MULTI INPUT* ST and the MULTI INPUT MONO jacks serve as additional stereo or mono input lines, as they can be
assigned to any output line.
•The LINE IN* jack at the front panel can be connected to a personal computer, MD player or CD player. 
*  The signal from MULTI INPUT ST/MONO jack(s) and the LINE IN jack are unavailable at the same time. (The LINE IN jack
has a priority to MULTI IN.)
●Basic functions
•Head amplifier with discrete construction (mono input)
•Electronically balanced output circuit
•Design for noise reduction and sound quality improvement (Refer to p. 38 SPECIFICATIONS.)
•Stereo input auto mute switch, used for information broadcasting in a shop
•Acrylic cover is attachable on the front panel to prevent wrong operation.
Note: In these Operating Instructions, Mono and mono stand for monophonic.

the appliance body.
Use a dry cloth to clean the appliance when it is dirty.
When the dirt is hard to remove, use a mild detergent
and wipe it gently.
•Do not operate the appliance beyond its specified
temperature, humidity or power source ratings.
Do not use the appliance in an extreme environment
where high temperature or high humidity exists.
Use the appliance at temperatures within 0 °C - +45 °C
(32 °F - 113 °F) and a humidity below 90 %.
The input power source for WR-XS3 is 120 V AC, 60 Hz
or 220 - 240 V AC, 50 Hz.*
