The Telex BTR-800 UHF Wireless Intercom Base Station with full-duplex beltpacks
Los Angeles Area, Dallas, San Francisco and Bay Area, San Diego Area, Orlando, Las Vegas, More Cities


In a vast majority of shows, the proper communications systems can make the difference between a sloppy show and a professional presentation. Generally whenever there are three or more technicians (especially if the are in separate locations) an intercom system is vital to the coordination of cues. As the number of people directly involved grows the need increases exponentially, and the requirement for sophistication of the system increases as well. Most professional intercom systems are quite simple in structure, setup, and operation. A basic system consists of a base station/power supply, local stations, headsets, and cabling.

On more complex shows where there are several groups of operators who must communicate among each other, a multi channel system is the best option. This way the electrician and spotlight operators can coordinate their cues, the video Technical Director can call camera shots, the production crew can coordinate with each other and the talent, and the sound crew can communicate, etc. the separation of the groups eliminates a logjam of cue calling at each major transition as well as allowing each group to communicate problems and issues that develop over the course of the presentation.

Wireless headsets are also a very beneficial addition if there are people in the crew who must have freedom of motion around the entire stage area. Wired headsets can limit the area of movement to a few feet while a wireless headset can allow the stage manager to go where every he is needed. It is also a good idea to give wireless headsets to the trouble shooters on the crew; once a trouble shooter must go off his wired headset to fix something, he is gone until that problem is fixed and he returns, regardless what may arise in the mean time.

A properly designed intercom system will improve the overall quality of a presentation as well as heading off many problems before they become apparent to the audience. This is a small investment to help insure a smooth presentation.


The Telex BTR-800 is a 2-channel, frequency-agile UHF wireless intercom Base Station, with channel access from each of four full-duplex beltpacks, stage announce output with relay closure, wireless talk around (ISO), the patented Enhanced ClearScan channel search feature, and a talk/listen headset station at the base.

The BTR-800 features a transparent graphical user interface and a backlit display, with advanced technology functions such as combination tone code/RF noise squelch and DSP digital audio processing.

This unit has a A4M Telex headset jack and works on A2 - 518-536 MHz frequencies.

The heavy duty beltpacks are durable and well layed out, because our Wireless Com system are there to make your life easier, not complicate it. The best part about the BTR-800 is our rental price - the same as our other RF intercom products!  Give us a call to reserve your booking

Standard Features:

1) Fully UHF
a) Both the transmitters and the receivers operate in the UHF frequency band.
b) Some Existing products are split band VHF/UHF mixed devices that have not performed well in hostile RF conditions and have not been well accepted in the marketplace among RF savvy users.

2) Fully User Synthesized
a) The user can select any TX frequency within the 18MHz transmit operational bandwidth in 25KHz increments – that’s 720 transmit frequencies to choose from for each of two transmitters!
b) The user can select any RX frequency within the 18MHz receive operational bandwidth in 25KHz increments – that’s 720 receive frequencies to choose from for each of four receivers!

3) Enhanced ClearScan™
a) Both the base station and the beltpacks can scan for clear frequencies and tell the user
which RF channels to set the system up on.
b) This is an advanced form of our existing ClearScan technology. It actually looks at all of the available frequencies in the pre-intermoded groups and ranks them so that the user knows the best frequencies to use.
c) A user can walk into a new venue in a new city and have a clear set of frequencies in less than a minute with the push of a couple of buttons!

4) Two Intercom Channels
a) Each beltpack can access two separate and distinct intercom channels, one at a time, which can be fed to the base station in 2 wire or 4-wire form. All beltpacks share access to the same two intercom channels and any combination of beltpacks can utilize either channel at any time.
b) Each intercom channel can be selected as either 2-wire or 4-wire. Selection is made via convenient front panel buttons with LED indicators for each for each channel.
c) The intercom 2-wire interfaces are completely AudioCom ® , RTS™ and Clear-Com ® compatible. No external interfaces necessary!

5) Wireless Talk Around (ISO)
a) The WTA (wireless talk around) button (sometimes called ISO in broadcast) on the
beltpack lifts the user’s audio off of the intercom bus and routes it to the other wireless beltpacks on his channel for a “private” conversation.

6) Stage Announce with Relay Closure
a) The Stage Announce button routes the user’s audio to a line level +8dB output on the back of the base station and triggers a relay closure for as long as the button is depressed.
b) This is a super feature that can allow a user to activate a two-way radio, greenroom speakers or a GPI input on a matrix intercom system.

7) LCD Displays
a) Both the base station and the beltpacks have LCD displays that allow the user to easily and quickly make changes to the operating parameters of the system.
b) This user interface is extremely intuitive and marks a substantial improvement in system usability over any other wireless intercom model.

8) “Fifth Person” Talk/Listen Station at Base
a) The base station has a standard 4-Pin XLR headset connection (reverse for RTS versions) that allows a fifth user to talk and listen (just like another beltpack) on intercom channel A or B or Both.

9) Intelligent Transmitter Power
a) The base station has two individual transmitters (one for each intercom channel - they share a common antenna) that each put out 100mW of power.
b) Each beltpack has one transmitter that normally puts out 50mW of power.
c) Intelligent Power? Yes! The beltpack senses when it is close to the base station and intelligently reduces it’s output to 10mW. This effectively eliminates the “near – far” desensing problem experienced in other wireless intercoms.

10) Numerous Beltpacks in Simultaneous Operation
a) With the current system architecture, any user using the pre intermoded groups can operate two base stations with up to eight beltpacks in any one operational band. Many more base stations and beltpacks can be coordinated by more RF savvy users (and rental houses) for high end RF venues.
b) Once the second band is available (Sept-01, see chart below) any user will be able to utilize 16 beltpacks in one location (2 base stations and 8 beltpacks per band) and power users will be able to use many, many more.

11) Cast Magnesium Beltpack
a) The beltpack is an extremely light, strong and durable cast magnesium. That’s the metal “Mag” wheels are made from! Metal, not plastic!

12) Detachable Beltpack Antennas
a) The beltpack has detachable antennas. This is great for shipping and storing. It is also a big plus if there is a service issue. The user can just buy new antennas rather than having to send the whole beltpack in for repair.
b) The antennas utilize a stud-type connector that does not have a fragile center pin to break off or bend.

Frequency Bands and Frequency Coordination:
The 800 ships with 24 Pre-Programmed groups of intermod free frequencies so virtually any user can get started right out right out of the box. More RF savvy users will also be able to save their own favorite frequency sets in easy to use User-Defined groups. These frequency groups, in conjunction with our revolutionary new Enhanced ClearScan technology offers users the most powerful, yet simple way, to select clear frequencies regardless of location or venue. The system will be sold in TX bands and RX bands (referenced as they relate to the base station). The chart below shows the bands that will be available first. The first two sets of frequencies will be A2 and C6. The A2 band, as shown below, will have a base transmit range of 518 to 536 MHz and a base receive range of 632 to 650 MHz. The C6 band will have a base transmit range of 554 to 572 MHz and a base receive range of 704 to 722 MHz. In the first few months of shipment the 800 will only be offered in the C6 configuration.

Frequently Asked Questions about Conference Interpreting

What is simultaneous interpreting?

Simultaneous Interpreting is when an interpreter listens to a presentation and relays it in another language with no significant delay.

What other types of interpreting are there?

Consecutive interpreting. This is where the presenter pauses after each phrase or sentence to allow the interpreter time to relay it into the other language. Although this is generally less expensive than simultaneous interpreting, the meeting will take twice as long as normal, and it can only be used when there are a maximum of two languages (usually English plus one other).

Are all simultaneous interpreters the same?

Simultaneous interpreting is the most difficult form of interpreting. Only a small percentage of interpreters can truly interpret simultaneously, that is: listen to someone speaking one language, and, without pausing, speak the same idea in another language.

A professional simultaneous interpreter should be able to speak both languages fluently, without a strong accent that would make him or her hard to understand. The best interpreters also speak in an interesting way so that their voices are a pleasure to listen to.

If your event will be discussing 'technical' subjects make sure you let us know when you request interpreters, so we can select those who have a background in your subject area. An interpreter who is very knowledgeable in legal matters may not be the best person for an electronics conference!

How many interpreters will I need?

Simultaneous interpreters generally work in pairs. This form of interpreting is very concentration-intensive, so the interpreters will normally work as a 'tag team' to cover the sessions. If the meeting lasts less than 1 hour, it may be possible for a single interpreter to cover it. For top-level events, such as government conferences, a team of 3 may be required. You might also need a team of 3 if the working day is very long. Most interpreters expect a working day to be between 6 and 8 hours of actual meeting time. Of course, if you have more than one room requiring interpreting at the same time, or more than one foreign language, you will need more teams of interpreters.

Tip: To keep expenses down, try to plan the schedule so that the meetings requiring interpreting take place one after the other, in the same room, rather than all at the same time in different rooms.

Can the same person be used to interpret from English to Spanish and from Spanish to English, for example?

Some interpreters are equally comfortable in both directions, others prefer to work only into their mother tongue. If you expect to need interpreting in both directions, be sure to let us know.

What kind of support will interpreters need to do their best work?

The most important support you can give your interpreters is written materials to prepare from. We cannot stress enough the importance of helping the interpreters prepare themselves for your conference. If possible, we recommend that you supply us with advance scripts of the presentations. If these are not available, you should procure abstracts, copies of overheads or PowerPoints that will be used, sales brochures, and a list of acronyms and abbreviations that may come up. You should also let us know of any web-sites that would give us background information. All materials should reach us at least a week before the first day of interpreting.

Expect to provide meals and refreshments and drinking water for your interpreters while they are working, and if they have been flown in from another city, you will need to provide all other meals too.

At meal and break times, remember to give your interpreters a break too. Do not expect them to do informal interpreting at the meal table for instance. By lunch-time, their brains may need to be 'de-fried', and that requires taking a break from thinking! If necessary, we can hire bi-lingual hosts to help facilitate meal-time conversations. Hosts are often available at much lower rates than professional interpreters.

What else will I need?

For simultaneous interpreting, you will also need to rent equipment so that your delegates can hear the interpreter's voice.
