The PRO UHF Wireless In Ear Monitoring System: D Debra audio's new UHF system with phase-locked loop PLL. It using high-quality IC chips, improves the overall performance, anti-frequency reduction, anti-series frequency, has a stronger and more stable signal, better signal to noise ratio. The frequency range is 510 MHz-580 MHz. The preset 100 frequencies for each channel can be switched at will, which can better avoid signal interference.
Suitable For Multiple Places: Built-in limiter circuitry eliminating distortion under excessive input levels. Front panel 1/4-inch monitoring has the headphone jack. Back panel have 6.35 mixed input and two channel independent integrated interface input. Good used in stage, broadcast, recording studio, musicians, band performance.
Feature Design: The transmitter has LCD display panel, RF and AF display. The receiver is equipped with LCD display, power supply and RF receiving indicator. The panel can monitor battery power.
More Stable Signal, Longer Effective Distance: On an unobstructed open stage, the effective distance can reach 800 feet. The best range is within 500-600 feet. The good the signal-to-noise ratio of the dynamic range, the good anti-interference and the perfect original sound reproduction.

Some tips to improve the performance of the system:
1. The transmitted and antenna should kept in the relative position of accessibility of the straight line.
2. Don't put the receiver close to the radio wave emission source, with magnetic objects or most digital devices (such as the CD player, computer, speaker, wifi etc).
3. Try to place the receiver in height of 1.5 meters from the ground and the position of a distance of 1 meter away from the wall.
