The SIEM-111 System features reliable JTS UHF PLL technology.
* There are 961 selectable UHF channels available. As many as 16 sets of SIEM-111T transmitters can operate on the same stage.* The system offers 4 groups, with each group having 16 compatible preset channels to choose from. This allows the monitor engineer to set up systems quickly and easily.
* MPX Stereo Audio Transmission / Reception, switchable to Mono operation if desired.
* All metal case construction on the SIEM 111R and SIEM 111T.
* The JTS advanced circuitry assures outstanding signal-to-noise ratio.
* IE-1 and IE-6 earphones seal off the ear canal with JTS designed Dyna-Driver ear buds which reduce undesired stage noise, ambient sound levels.
* 3 pairs of different sized Silicon sleeves included with the IE series earphones ensure a right fit for the users ear canal and comfort.
IE-1
* This wideband dynadriver earphone reproduces full range of frequency, natural mids, and full highs and bass. It delivers sound musicians want and should be heard with full detail.
* Three pairs of silicon sleeve are provided with different sizes for best fitting and sound isolation.
* Human friendly mechanical structure ensures long time fatigueless wearing.
* Ergonomic design for long-time wearing without fatigue.
