The Sennheiser SR 300 IEM G3 monitoring system takes wireless monitoring to the next level. The in-ear stereo transmitter has an integrated 5-band equalizer for extra sound control. Pass-through sockets for the audio signal enable the audio feed from a console to be routed to other devices in the chain, simplifying your setup. The enhanced audio frequency response of 25 to 15,000 Hz means the performers hear the most accurate sound possible from this in-ear wireless monitor system. The enhanced frequency bank system reserves up to 16 compatible frequencies to maintain a crisp, clear sound. An Ethernet port allows for connection to the Wireless Systems Manager (WSM) software for control via computer-this delivers a good overview of monitoring and professional data management for multi-channel systems. The Sennheiser SR 300 IEM has an Auto-Lock function that avoids accidental setting changes. Lastly, the entire set can be monitored and remote-controlled, with Sennheiser's "Wireless Systems Manager" software built in the stereo transmitter.
