Meyer Sound MJF-212ATM Manuale Utente

8

 For best performance, the AC cable 

voltage drop should not exceed 10 volts, or 

10 percent at 115 volts and 5 percent at 230 volts. 
Make sure that even with the AC voltage drop, the 
AC voltage always stays in the operating windows.

The minimum electrical service amperage required by 
an MJF-212A system is the sum of each loudspeaker’s 
maximum long-term continuous current. An additional 30 
percent above the minimum amperage is recommended to 
prevent peak voltage drops at the service entry.

Pay close attention to these important electrical and safety 
issues.

 

 In the unlikely event that the 

circuit breakers on the monitor’s user panel 

trip (the white center buttons pop out), disconnect 
the AC power cable. Do not reset the breakers with 
the AC connected. Contact Meyer Sound for repair 
information.

 

The MJF-212A monitor requires 

a grounded connection. Always use a 

grounded outlet and plug.

 

Do not use a ground-lifting 

adapter or cut the AC cable ground pin.

 

Do not exceed the current 

capability of the monitor’s 20-amp AC 

connector. When looping, always take into account 
the current draw of all loudspeakers on the circuit, 
including the first unit. 

 

Make sure that the power plug 

is appropriate for the AC power at the site 

where you will operate the MJF-212A monitor. In 
addition, the connector must be rated for the total 
load of 

all MJF-212A loudspeakers looped to the 

same power plug.
