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 connectors 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".

INSTALLATION
■ Work Flow ■ Before Installation
Caution:
Contact your dealer for installing the unit.
Be sure to toggle the power off and unplug the unit from
the receptacle before installation. Follow the safety
instructions.
● Power Connection
Connect the power cord by any of the following methods,
making sure to provide a breaking device in each case.
(1) Connect the power cord to the power control unit.
(2) Install the unit near a receptacle and connect the power
cord to the receptacle via a breaking device. The
breaking device should be installed near an operator.
(3) Connect the power cord to a circuit breaker in a panel
board that has a contact distance of 3.0 mm or more.
Use a circuit breaker that will interrupt each circuit of
the main power supply (except a ground-protective
conductor).
● Installation Place
• Install the unit out of direct sunlight and away from outlets of heated air. Installation in a humid, dusty or shaky
place may cause trouble.
• Keep a distance between this unit and a transformer,
dimmer, image device, CRT monitor, etc. as much as
possible. Failure to do this may cause induction noise.
● Rack Mounting
Keep the temperature in the rack below 45 °C . Failure to
do this may cause damage to internal components.
● Grounding the Unit
Ground the unit by the grounding terminal at the rear side.
If the devices are connected in unbalanced connections,
synchronize each grounding potential as follows:
• Synchronize the power supply phases.
• Synchronize the power supply lines.
• Connect each device's grounding terminal or chassis
with a thick grounding wire of each device.
Failure to do this may cause induction noise.
Note: If the unit is placed more than 10 m away from
other external devices, grounding the unit near an unbalanced external device is recommended.
● Condenser Microphone
• When using a condenser microphone, connect it to an
external device.
• Do not connect external devices supplying phantom
power, as it may damage the unit.
12
Secure the unit by 4 pieces of rack
mounting screws (M5 x 12) in the
accessories.
Where to install How to install
1. Install the unit on a rack.
Apply the screws in the accessories.
Note: Attach the four rubber feet if not installing the unit in a rack.
Cautions:
• When mounting this unit in a place where it is frequently subject to vibrations, secure its rear to the rack with reinforcing
angle steel (manufactured locally) or other materials.
• Keep the temperature in the rack below 45°C.
• Place this unit below heat-producing devices such as amplifiers if possible.
• If placing the unit below and above heat-producing devices such as amplifiers cannot be avoided, keep a distance of 1 U
or above the heat-producing devices.
• Use the rack mounting screws (nominal diameter: 5 x 12) supplied with the brackets if the mounting positions of the rack
are not tapped. If the screws are used at tapped positions of the rack, the original threads may be destroyed.
• The rack mounting screws in the accessories do not fit all types of racks. In that case, use the screws included with the
rack or buy your own screws.
■ Mounting into the Rack
● Rack
Use either one of the following racks for mounting the unit.
Standard: WU-RS71, capacity of 29 U (Panasonic)
Long: WU-RL76, capacity of 41 U (Panasonic)
EIA standard-compliant: depth 450 mm or more (other than Panasonic)
● Items to prepare
If you use a rack supplied by other than Panasonic, it may require four rack mounting screws (option) or four M5 x 12 screws.
(If you use a Panasonic rack, you can use the tapping screws supplied with the rack.)
Attach 4 rubber feet.
