Sennheiser EK IEM G4 Stereo Bodypack Receiver, IE 4 Earphones, A: 516 - 55

Robust bodypack receiver delivering clarity along the whole frequency spectrum for daily use on stage with evolution wireless G4 In Ear Monitoring systems.Architect's SpecificationThe compact monitor receiver with adaptive diversity technology is for use with a companion transmitter as part of a wireless RF monitoring system.The receiver operates within nine UHF frequency ranges, with a switching bandwidth of up to 42 MHz: 470 - 516 MHz, 516 - 558 MHz, 520 - 558 MHz, 626 - 668 MHz, 734 - 776 MHz, 780 - 822 MHz, 823 - 865 MHz, 566 - 608 MHz, 606 - 648 MHz; transmission frequencies are 1,680 per range and are tunable in 25 kHz steps. The receiver features 20 fixed frequency banks with up to 16 compatible frequency presets and 6 user banks with up to 16 user programmable frequencies.The receiver is menu-driven with a backlit LCD display showing the current frequency, frequency bank and channel number, metering of RF level, metering of AF level, lock status, battery status, muting function or audio channels, and pilot tone evaluation. An auto-lock feature is provided to prevent settings from being accidentally altered.The receiver parameters is either configurable in the associated transmitter's menu and synchronized with the receiver via an integrated infrared interface or is programmable in the receiver menu.The earphone output utilizes a 3.5 mm stereo jack socket with an output level of 2.4 V with 5 % THD at nominal deviation and an output power of 2x 100 mW at 32 Ohm.Nominal/peak deviation is +/-24 kHz/ +/-48 kHz. Squelch threshold is defeatable (off) or adjustable from 5 - 25 dBmicroV in steps of 2 dB.The receiver incorporates the Sennheiser HDX compander system and a defeatable pilot tone squelch. Sensitivity is < 4 microV, 1.6 microV (typical) for 52 dBArms S/N with HDX engaged at peak deviation. Adjacent channel rejection is >= 65 dB (typical). Intermodulation attenuation is >= 70 dB (typical); blocking is >= 80 dB.Signal-to-noise ratio at 1 mV and peak deviation is approx. 90 dB. Total harmonic distortion (THD) is
