Wireless Personal Stereo Monitor System
The Shure ® PSM ® 900 Wireless in-ear monitor system is used for on-
field/on-stage talent. The system allows for personal adjustment of
mix and volume and compensates for delay from the sound system.
Sound travels at 1120' (341 m) per second. This produces a noticeable
delay as one moves away from the speaker. Even experienced
performers have trouble adjusting to this delay. A wireless in-ear
monitor system provides a real-time signal to the talent and blocks the
sound delay from their ears.
Note: If more receivers are required and the transmitter is already
installed, additional receiver packs and headphones are available
to purchase.
