All-in-One Mixer and Amp

From the simplest to the most complex public address needs, the WA-MA120N and WA-MA240N have what it takes. These mixing power amplifiers combine multiple inputs with assigned priorities and call signs to provide the flexibility required for applications ranging from schools and business facilities, factory, office and religious buildings. To ensure more efficient and reliable communication, options including program broadcasting and troubleshooting.

The Public Address System Made it Easy.

2-channel Broadcast

Background music and announcement transmission can be transmitted independently to any of three zones, with background music transmitted to one zone and announcements transmitted to another zone.

*2-channel broadcast requires the optional WA-BA240N Booster Power Amplifier

Up To Four Remote Microphones

Up to four (4) WR-210AE remote microphones can be used to broadcast from remote locations. These remote microphones can be used for individual, group, all-at-once or simultaneous broadcast.

Add Up To 30 Zones

Depending on scale of application systems may include up to ten (10) WA-MA120N or WA-MA240N mixing power amplifiers for expansion to up to 30 zones.

Broadcast Simultaneously To Multiple Remote Areas

For example, facilities with multiple buildings can have a WA-MA120N or WA-MA240N installed in each building. Via the simultaneous broadcast BUS I/O connector, broadcasts can be directed to selected all buildings at once.

Program Broadcast

With the optional WU-ZM001E Sound Message Unit, an SD memory card can be used to store MP3 data to be broadcast for a week at specified days and times. The SD memory card holds 100 messages.

Troubleshooting

The optional WU-ZS001E Surveillance Unit checks at preset intervals (or 24-hours a day) for overheating and sound and speaker irregularities.

Reliable Cooling

Cooling fan control is provided by two thermal sensors monitoring temperatures inside the case.

Energy Saving Design

This mixing power amplifier uses Class-H amplifier technology developed by RAMSA, the Panasonic Professional Audio Group, to minimize power consumption.

WA-MA120N/WA-MA240N

INSTALLATION

AC Voltage Setting

• Before plugging the AC power plug into the mains, make sure the VOLTAGE SELECTOR switch on the back of the Amplifier is in the proper position.

• The factory preset is 220 V to 240 V. The Amplifier will not operate correctly if the VOLTAGE SELECTOR is set to 220 V to 240 V while the AC voltage is 110 V to 120 V.

CONNECTIONS

Important:

• The Amplifier's output power cannot be increased if multiple Amplifiers (or WA-BA240N Booster Power Amplifier) are inputting and outputting the same signal "in parallel operation" because it will short circuit. Absolutely do not connect the Amplifiers together in parallel operation, doing so may result in a malfunction.

Backup for AC Power Cut

• Do not use UPS (Uninterruptible Power Supply) as backup in case of AC power cut. Use external batteries instead.

Replacing the Fuse

• If the fuse blow, replace it with a fuse that is the same shape and capacity. The wrong type of fuse will be prone to blowing even under normal conditions, and creates the risk of danger if the Amplifier malfunctions.

Rack Mounting Precautions

External Battery Precautions

Note the following precautions when using an external battery.

• Make sure the external battery is a 24 V Lead Acid battery (or two 12 V batteries in series connection). Panasonic Corporation holds no responsibility for any Amplifier fault operation or other inconveniences resulting from using any other batteries except that indicated above.

•

Use the formula below to determine the battery capacity that is necessary to support the amount of operating time required. Note, however, that the actual amount of operation time provided by a battery varies greatly in accordance with the Amplifier's signal output Level.

•

When connected to an external battery, the Amplifier will automatically switch to the battery power supply once the AC power supply is cut off by turning off the POWER switch or due to power cut. The battery power is not cut off even when the POWER switch on the back of the Amplifier is turned off. The battery power consumption continues even when both the OPERATE and the POWER switches are off and the OPERATE indicator remains lit amber. Use the formula below to determine the battery life.

To save the power of the battery, switch off both the POWER and the OPERATE, remove the battery if the Amplifier is not in use for a long period.

•

No battery power will be consumed only if the AC power is connected. And the Amplifier has no built-in battery charger. Note that the battery discharges even when it is not in use, so observe the battery's instructions and check the battery periodically. Be sure to remove the battery from the Amplifier before charging. And charge the battery properly according to the instructions of the battery and the battery charger.

•

The Amplifier operates normally with the battery voltage over 21 V, and audio output malfunction may occur if the voltage is lower than 21 V.

Battery Capacity [AH] = Amplifier Normal DC Consumption Current [A]* x Required Operating Time [H]

* Based on IEC60065 standards. Refer to the SPECIFICATIONS (page 48).

Battery Life [H] = Battery Capacity [AH] ÷ Amplifier Standby DC Consumption Current [A]*

* Please refer to the SPECIFICATIONS (page 48).

WA-MA120N: 15 A WA-MA240N: 30 A

Cautions:

• Refer all work related to the installation and maintenance of the external battery to qualified service personnel or system installers.

• Be sure to turn off power (AC) before installing or removing a battery. To protect the battery, provide one of the fuses shown below between the battery + terminal and the Amplifier's + terminal.

Take care to ensure proper battery polarity and to avoid shorts while working.

Installing Rack Mounting Brackets

• Installing the supplied rack mounting brackets lets you configure the Amplifier for rack mounting.

1. Remove the screws (M5 x 16) from both

sides of the Amplifier.

2. Use the four screws (M5 x 16) to attach

the rack mounting brackets.

• Also remove the four rubber feet on the bottom of the Amplifier by using a flat blade screwdriver to pry out the pins that hold the feet in place.

Battery Connection

• Use the formula below to determine the battery capacity that is necessary to support the amount of operating time required. Note, however, that the actual amount of operation time provided by a battery varies greatly in accordance with the Amplifier's signal output level.

Operation On/Off Control

• Operation On Control and Operation Link Control

The Amplifier can be put into the operation mode externally by no-voltage make contact. The Amplifier can also cause other linked equipment to enter operation mode when it enters the operation mode.

Important:

• In order for external operation control to be performed, the POWER switch on the back of the Amplifier must be ON, and the OPERATE switch on the front must be OFF so the Amplifier is in the non-operation (standby) mode. The Amplifier's current operation/non-operation mode is determined by the relationship between external control (no-voltage make contact) status and the Amplifier's OPERATE switch setting.

• Operation Off Control

The Amplifier can be put into the non-operation (standby) mode externally by no-voltage make contact. Use this capability when you want to terminate business announcements from this Amplifier during announcements from external emergency announcement equipment.

Important:

• In order for operation off control to be performed, the POWER switch on the back of the Amplifier must be on, and the OPERATE switch on the front must be ON so the Amplifier is in the operation mode. The Amplifier's current operation/non-operation mode is determined by the relationship between external control (no-voltage make contract) status and the Amplifier's OPERATE switch setting.

Caution:

Be sure to turn off power (AC) before installing or removing a battery. To protect the battery, provide one of the fuses shown below between the battery + terminal and the Amplifier's + terminal.
