Shure U1 Body Pack

The U1 body-pack is a compact transmitter. The U1 functions with the full range of Shure lavalier, head-worn, and instrument microphones, as well as guitar cables. These body packs support the full range of Shure lavalier, head worn and instrument mics as well as guitar/bass cables.  The pack has a standard 4 pin mini connector to allow quick and easy changes from microphones to headset, ear-set, etc.  These units also have an easy-to-read, programmable, multi-function LCD to set and view: Group and channel, Five-segment battery fuel gauge, Frequency lock, power lock, and on/off status.  They come with a 1/4 wave whip antenna and a LED power on indicator.  There is a 3 position attenuator switch for adjusting input on the back of the pack, and a complete adjustable audio gain attenuator inside the pack.  Please note these units allow the technician to power and frequency lock to ensure no missed presentations due to packs being turned off, or muted. The Shure U1 packs are very rugged and their durable all metal housing will with stand drama, dance, and concerts.  The two AA batteries will produce a solid 12-hour transmission period.

Please note for this wireless ear-set system to function, you require a 3 items, this body-pack as detailed, receiver set to the frequency the body-pack is transmitting, and an input transducer such as this ear-set, headset, or microphone capsule such as the WL185, or a smaller capsule such as the WL93. If this is required or an instrument, please be sure to let us know so we can include a WA302 in your rental package.

Of coarse when this system is rented from us, we will ensure it is ready for your use with two simple connections, one into a wall plug for power, and the other connection into your sound system with a simple microphone cable.  If you require a sound system - we are pleased to assist you with selecting only the required items for your sized venue also.
