8.3.2. Power supply and limit on the number of remote microphones
The number of remote microphones connectable in a system is as follows.
• Up to 2 RM-200SFs and up to 6 RM-300Xs and RM-500s (8 units in total) can be connected to the VX-3000F.
• Up to 4 RM-320Fs can be connected to the RM-200SF, and up to 7 RM-210Fs to the RM-300X.
The method of power supply to the remote microphones differs depending on the system application and
conguration, and also type of remote microphone. In a system conguration, the allowable number of the
microphones connected to the VX-3000F may be limited.
[Power supply to the remote microphones]
Note : Red lines are DC power lines. Black lines are other control lines.
• Each of the VX-3000F's RS LINKs A and B is capable of supplying the maximum current of 1 A. Ensure that
the total current consumption of the remote microphones to be connected to each RS LINK is 1 A or less.
When power is not supplied from an AC adaptor or the VX-3000DS or the VX-3150DS, the number of the
remote microphones connectable to each RS link is up to 2 units in combination of the RM-200SF, RM-300X,
and RM-500.
• If the total current consumption of the remote microphones to be connected to each RS LINK exceeds 1 A,
the AC adapter or VX-3000DS or VX-3150DS is additionally required to compensate the power supply for the
excessive amount of current.
• If a remote microphone does not need to operate during power failure, the AC adapter can be used to supply
power to it.

[Current consumption of the remote
microphones]
Model No. Current Consumption
RM-200SF 240 mA
RM-320F 180 mA
RM-300X 240 mA
RM-210F 80 mA
RM-500 130 mA
(Example)
RM-200SF x 1 240 mA x 1 = 240 mA
RM-320F x 2 180 mA x 2 = 360 mA
RM-300X x 1 240 mA x 1 = 240 mA
RM-210F x 2 80 mA x 2 = 160 mA
Total 1000 mA ≤ 1 A
