PREFACE
The WA-MA120N/240N is a Mixing Power Amplifier that
features multi-input, announcement priority control, call tone,
and other features.
You can select either a 120 W model (WA-MA120N) or 240
W model (WA-MA240N) to suit the structure of your system.
Features such as 2-channel announcement, Remote
Microphone announcement, zone expansion capabilities,
all-zone announcement between different work areas, and
other features provide outstanding system flexibility that
meets the needs of a wide range of applications, including
retail outlets, businesses, office buildings, factories, schools,
and more.
The term "Amplifier" in this manual refers to the Panasonic
WA-MA120N/240N Mixing Power Amplifier.
FEATURES
Can be configured as a 1-channel or 2-channel
broadcast announcement system.
Supports connection of up to four Remote
Microphones (WR-210AE). Individual zone, group, all-
zone, and 2-channel broadcast announcements are all
supported from Remote Microphones.
Expansion to up to 30 zones is supported by
combining up to 10 Amplifier units.
When multiple Amplifier units are used in combination,
all-zone announcement is supported even if each area
has a different system configuration.
Other Functions
• Multiple inputs for two line inputs, three microphone/line
inputs, one Remote Microphone input, one telephone
paging input, and one EMG input. Supports connection to
business and emergency announcement equipment at a
single location.
• Announcement priority control with four 1-channel
announcement priority levels (fixed). In case of an
emergency call or emergency announcement, lower
priority announcements are blocked automatically in
accordance with the priority levels.
• Easy switching of high impedance loudspeaker output
voltage between 100 V and 70 V for plenty of flexibility to
adapt to the needs of each system.
• Equipped with REC OUT, LINE OUT, INS IN/THRU/
OUT. The Amplifier can be expanded while connecting
equipment to enable announcements required for
operation of a particular business.
• External attenuators can be bypassed during all-zone
announcement. This allows emergency announcements,
even when an attenuator is being used in a local area.
• Operation on/off control can be use for remote switching
between operation and non-operation modes.
• Connecting a battery (24 V) allows continued operation in
case of a power outage.
2-channel Broadcast Announcement
• This Amplifier supports 2-channel broadcast announcement from INPUT 1 or a Remote Microphone.
• The illustration below shows the concept behind 2-channel broadcast announcement. This function can be used to announce
to zone 1 only, without interrupting the BGM being played in zones 2 and 3. Note, however, that zone1 2-channel broadcast
announcement is cancelled during all-zone announcement. Because of this, it coincides with the 1-channel announcement and
the output audio signal priority for zone 1 is shown in the table below.
