(1) Input Connector
This professional 2P screw terminal speaker jack is used to input the amplified high level program sources coming
from the external power amplifier.
Caution: Pay more attention to the connection of the speaker cables, only connect the + terminal of the speaker jack
to the + output of the amplifier, vice versa.
Detail connecting information, please refer to the " WIRE CONNECTIONS".
(2) NEAR or FAR field selection
Via this switch, you can apply your M series monitor speakers in the near field or far field configuration.
Generally, near field option is designed for the near distance monitor which is mainly used in the smaller sound system,
and the speakers are placed relatively close to the listener, normally about 1~1.5m.
By the near field monitoring, you can try to avoid the interference caused by the acoustic environment, esp. the reverb
effect, and do the serious mixing.
As for far field option, it is usually designed for the larger sound systems, where the monitor speakers are placed comparative farther away from the listener.
