Sennheiser EK 300 IEM Receiver (GB)

This bodypack receiver has adaptive diversity for reliable reception; the headphone cable is utilised as a second antenna. The upper surface has a volume control, a locking, 3.5mm, stereo jack socket, for the earpiece and a whip antenna.

The front has a backlit graphic display, offering ‘intuitive menu navigation’ and a ‘user-friendly menu’ in conjunction with an up/down rocker button and set button. A standard display is presented at switch-on, showing RF signal levels, squelch threshold, transmitter modulation levels for the two audio channels, current transmission frequency, the name of the receiver, lock-mode status, battery status, mute status and whether the pilot tone is activated. Two alternative standard displays may be chosen, showing the limiter status, channel number, equaliser settings and stereo/focus mode, and other information in different combinations. Control functions include a ‘Hi Boost’, a multi-level limiter, stereo/focus mode and balance. An ‘auto-lock function’ avoids accidental changing of settings. LEDs indicate battery status and RF signal indication. The front folds down to reveal the battery compartment for 2x AA cells or a BA 2015 accupak rechargeable battery pack and the ‘set’ and ‘escape’ buttons. On the rear there is a removeable metal belt-clip.
