Round off your Sennheiser Tourguide System with the EK 2020-D receiver. Whether conferences, guided tours or hearing assistance: this extremely sturdy and versatile bodypack receiver provides excellent audio and ease of use for your guests. The EK 2020-D can be used with headphones or an induction neckloop for transmitting the sound to hearing aids equipped with a T coil. Digital transmission ensures optimum reception quality, with a range of up to 100 metres outdoors and around 50 metres indoors. The backlit receiver display shows all settings at a glance. Of course, the bodypack receiver can be used in mixed systems with stethoset receivers.

EK 2020-D: just right for everyone. All your guests need to do is connect their headphones or induction neckloop to the receiver. That's it! The receiver can conveniently be clipped to the shirt pocket or worn on a lanyard.

Audio-Technica MCB4 Antenna Combiner allows the signals of up to four M3 Wireless In-Ear Monitor stereo transmitters to be combined onto a single transmitting antenna, reducing rack clutter.

A wide-band unit that operates over the 440-865 MHz range, the MCB4 is designed to complement Audio-Technica M3 Wireless In-Ear Monitor Systems. It is also suitable for many other in-ear wireless systems (with external BNC antenna connections) operating within the 440 to 865 MHz range. The MCB4 provides one output and four isolated transmitter inputs. All RF connectors are BNC-type.

Four jacks on the rear panel (controlled by the unit's power switch) provide 12V DC (centre positive) to power as many as four transmitters operating on 12 volts at up to 600 mA each. Included with the unit are four DC cables appropriate for use with M3T (or like-powered) transmitters. The 12-volt supplies for powering transmitters are short-circuit protected. The unit features all-metal construction for extreme durability and protection from radio frequency interference.

This wireless monitoring set's receiver uses adaptive-diversity technology. The earphone cable serves as a second antenna, which considerably reduces the number of drop-outs. Combined with IE 4 ear-canal phones for precise sound reproduction, EK 2000 IEM conveys an authentic acoustic pattern of live sound and allows you to monitor your own performance perfectly.

Audio-Technicaʼs System 10 Stompbox digital high-fidelity guitar wireless system combines the advanced 24-bit operation, easy setup and clear, natural sound quality of other System 10 configurations with unique functionality for guitarists, bassists and other instrumentalists. Operating in the 2.4 GHz range, far from TV and DTV interference, System 10 Stompbox offers a rugged, metal, pedal board-mountable receiver with foot switch, two switched TRS balanced 1/4" outputs and an output mode selector. With the tap of a foot, musicians can toggle between outputs (e.g., for switching amps) or mute and unmute one output without muting the other (e.g., for convenient tuning). And a single receiver can be paired with up to eight UniPak® body-pack transmitters, allowing users to easily switch between instruments without having to move a body-pack from one instrument to the next.

System 10 wireless ensures clear communications by providing three levels of diversity assurance: frequency, time, and space. Frequency Diversity sends the signal on two dynamically allocated frequencies for interference-free communication. Time Diversity sends the signal in multiple time slots to maximize immunity to multipath interference. Finally, Space Diversity uses two antennas on each transmitter and receiver to maximize signal integrity.

Each Stompbox system includes an ATW-R1500 Stompbox receiver, an ATW-T1001 UniPak body-pack transmitter with an AT-GcW guitar cable, and hook & loop strips for adding receiver to an effects pedal board. The ATW-R1500 is a digital receiver with sturdy, metal-body construction, easy-to-read digital ID and transmitter battery level displays, and AF Peak and Pair indicator lights.
