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.
