Therefore, small specification changes may not be reflected in this catalogue. Images, labels, packaging, accessories and product colours are subject to change without notice. Radio frequency systems provide clear sound for assistive listening in small or large public venues, and in tour guide applications. Contacta RF assistive listening system ideal for when sound sources need to be wirelessly transmitted across large areas, sending signals through walls, ceilings or other obstacles regardless of building characteristics. Transmitters are connected to an audio source such as a microphone or PA system and send signals to compatible RF receivers. Our system can utilise up to 42 channels simultaneously with a range of up to 100 metres in buildings. Receivers can be used with Inductive Neck Loops, allowing users to receive the sound directly in their T Coil enabled hearing instrument. 3 Transmitters Radio Frequency Rack Transmitter RF-TXRM-865 / RF-TXRM-915 The Radio Frequency Rack Transmitter, available in either 865MHz or 915MHz (USA/AU) frequencies. It uses internationally approved FM frequencies to transfer clear sound to portable receivers (see page 10). It is designed to provide wireless and amplified assistive listening in large venues from a sound source to compatible RF receivers using FM radio waves. Applications: Designed to deliver wireless FM assistive listening in large public venues and for interpretation. · Lecture Halls · Auditoriums · Meeting Rooms · Conferences · Places of Worship What's in the Box: · Radio Frequency Stationary Transmitter · Power Supply Adaptor · 19" Rack Mount Bracket · Earth (Ground) Cable for Optional Use · Fixing Screws · TNC Rod Antenna Compatible Accessories · Portable Radio Frequency Receiver (see page 10) · Remote Antenna Kit (see page 19) Physical Data: Dimensions Weight Finish Height 51mm (2") Width 215mm (8.46") Depth 210mm (8.26") 1.25kg (2.75lbs) Mixed Product Code: Radio Frequency Rack Transmitter RF-TXRM-865/915 See next page for Technical Data. 4 Transmitters Assistive Technology Technical Data: Carrier Frequency Range RF Output Power Antenna Headphone Output Inputs Mic/Line Inputs XLR Connector Mic-In Connectors Connectors Outputs Wireless Coverage Power Requirements Frequency Response Channel Display Software 865MHz (UK/EU) / 915MHz (USA/AU) (country dependent) Hi: 18 dBm Mid: 13 dBm (country dependant) Lo: 10dBm TNC connector 200mW @ 32 ohm Mic in: 3.5mm & 6.3mm Aux in: RCA Loop in: 6.3mm Incoming BluetoothTM streaming Mic Input: -30dBv Line Input Limits: 10dBv Unbalanced/Balanced connections available Level= \-30dBv Balanced Connection Mono/Stereo Aux out-Mono Mic Level--30dBv AUX IN = Audio Source MIC IN = Dynamic Mics PH PWR = Electret Mics Earmic out: 3.5mm, stereo Aux out: RCA Loop out:6.3mm Approx. 100 meters (line of sight @ Hi power) 100 ~ 240 V AC / 12 V DC, 1A switching power 70Hz - 12kHz 42 channels are accessible on the 865MHz version. 25 channels are available on the 915MHz version Backlit OLED Smart programming software for fast set-up of multiple receivers Front / Rear Panels: 5 Transmitters Portable Radio Frequency Transmitter RF-TX1-865 / RF-TX1-915 The compact Portable Radio Frequency Transmitter sends signals of speech or music to compatible portable receivers (see page 10) across selectable channels.
