Caution: hot and sharp surfaces! This professional device needs to be installed by qualified per-
sonnel only.
Please check the packing for any kind of damage upon reception of the goods. If the packing is
damaged, please contact your dealer before opening it.
!!!! Danger!!!! Exposure to high sound pressure levels may cause permanent hearing loss. Hear-
ing loss induced by exposure to high sound pressure levels will vary from individual to individual,
but nearly everyone will lose some hearing when exposed for a sufficient amount of time. There-
fore it is recommended that all persons exposed to equipment capable of producing high sound
pressure levels, such as this amplifier, wear sufficient ear protection while installing or operating
this unit.
Read all documentation before operating your equipment.
Keep all documentation for future reference.
Keep the carton and packing material, even if the equipment has arrived in good condition.
Should you ever need to send the unit back, use only the original factory packing.
Do not spill water or other liquids on or into the unit.
Make sure power outlets conform to the power requirements listed on the back of the unit.
Do not use the unit if the electrical power cord is damaged.
Always operate the unit with the AC ground wire connected to the electrical system ground.
Turn the level controls on the amplifiers all the way down during power-up to prevent speaker
damage if there are high signal levels at the inputs.
Do not connect the inputs / outputs of amplifiers or consoles to any other voltage source, such
as batteries, mains sources or power supplies, regardless of whether the amplifier or console is
turned ON or OFF.
Power down and disconnect units from mains voltage before making connections.
Do not use the unit near stoves, heat registers, radiators, or other heat producing devices.
Do not operate equipment on a surface or in an environment which may distort the normal flow of
air around the unit. If the unit is used in an extremely dusty or smoky environment, the unit should
regularly be “blown free” of dust.
Do not remove the cover. Removing the cover will expose you to potentially dangerous volt-ages.
Do not drive the inputs with a signal level higher than that which is required to drive equipment to
full output.
Do not run the output of any amplifier back into another input.
In case of malfunction, this device should be serviced by qualified service personnel only.
Safety first!

- Loudspeaker output connector zone 5 zone 5 is a 70 volt speaker line output compatible with 100 10
- Loudspeaker output connector zone 6 zone 6 is a 70 volt speaker line output compatible with 100 10
- Present on the preamp out connectors you can activate the emergency input by closing a contact between the gnd and prior connections or alternatively activate the input by setting the automatic vox circuitry set the internal jumper marked s3 to the vox position and set the threshold level with vr13 the jumper and level adjustment are located inside the unit on the rear pcb in order to reach them you will need to open the unit for authorized persons only 10

- Selective paging without an external paging amplifier will cause interruption of the bgm in the non paged zones in case a zone is being paged the ma247 mr will bypass the internal zone level control caus ing the paging message to be heard at full level in the selected zone s when external volume control lers are in use connect the 24v priority input of the controller to the dedicated 24v zone output of the ma247 mr 17
- What about external volume controls if you use additional external volume controls such as our e vol series be sure to connect the 24 volt priority output from the ma247 to the volume control s 24 v priority input this will bypass the external volume controls allowing paging messages to be heard at full power there is a general 24vdc output and also an individual per zone 24vdc output available max current supplied is 0 a in total with a limit of 0 a for the individual zone outputs as a general rule a normal external volume control such as our e vol series volume controllers con sume about 50 ma when priority is active as a result the ma247 can feed a maximum of 12 external volume controllers 12 x 50ma 0 a with a limit of 6 controllers per zone 6 x 50ma 0 a when third party external volume controllers are in use please check the supply current and polarity of the priority inputs 17
