- 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
