General Description The Tempest 2400 Wireless Intercom System is a four-channel wireless intercom system that operates with up to five wireless beltstations per base station in full duplex simultaneous operation. Tempest operates in the non-licensed RF band at 2.4GHz. Tempest wireless systems will not interfere with traditional wireless microphone, IFB or in-ear monitor systems that operate in the UHF TV band.
Wireless beltstations are also compatible with hardwired system features such as Call and Mic Kill. In addition to the shared Stage Announce relay, each wireless beltstation controls its own unique relay that can be associated with additional events or actions at the beltstation. Tempest 2400 series base station comes standard with two RP-TNC RF antenna connectors and an RJ45 connector for remote RF transceiver operation.
Theory of Operation Tempest uses Frequency Hopping Spread Spectrum (FHSS), Time Division Multiple Access (TDMA), and 2xTX technology. For example, on Frequency 1 the base station and each beltstation take turns broadcasting, each with its own time slot to send audio data (TDMA). The total time for one cycle is 5 milliseconds (1/200 second).
orthogonal frequency relationship of the consecutive redundant packet transmission, the potential for loss of any single audio packet (2 consecutive data packet transmissions) is dramatically reduced. In addition, each packet transmission is sent out from different antennas. This unique approach enables Tempest to utilize spatial diversity, frequency diversity, time diversity and polarization diversity.

Other Items You May Need Headsets A Headset is required for each user (XLR-4F connectors). Headsets may use Electret or Dynamic microphones. Most major brand headsets that have the correct XLR-4F connector should be compatible, requiring nothing more than a simple Mic Gain adjustment. DC Power input cable If you plan to power the Tempest base station via DC power (Battery) instead of AC power, you will need to provide a DC Power input Cable.
¼” Tip/Ring/Screen Connector The pin-to-pin connections are shown in the table below. Connector 1 Screen Ring Tip Connector 2 Screen Ring Tip Stage Announce XLR-3F Cable If you plan to connect the Tempest base station to an external audio device via the Stage Announce connector, you will need to provide the appropriate XLR-3F cabling.
Choose a Location A Tempest Base Station mounted in an equipment rack. Choosing a location for your Tempest base station and the associated antennas is one of the most important factors to ensure proper system operation and achieve maximum operational range. As covered in the General Information and Theory of Operation section of this manual, Tempest is a radio system, broadcasting and receiving RF signals that can be greatly affected by physical and electromagnetic barriers.
Power Connections AC Power Connection The Tempest base station can be powered from AC or DC (battery) power sources. Always connect the power cord to the Tempest base station before connecting to the outlet. Only use approved IEC AC power cords. Only use AC power from 85 to 260 VAC at 50 – 60 Hz. DC Power Connection (Battery) To power the Tempest base station from DC power you must provide an appropriate DC power input cable. The DC power input jack on the base station is a Switchcraft 722RA.
Antenna Location Wired Intercom Connection Proper antenna location is essential for the best system performance and maximum range. Antenna positioning is important with all RF systems and in all applications. Locate the Tempest base station antennas as high as possible for your application to maximize line-of-sight RF operation. Positioning the antennas higher than head level is the minimum acceptable height for most applications.
Antenna Configuration Install the base station in the center of the area of Communication, with antennas installed on the back of the base station, having a clear line of sight in all directions. It is necessary to have both antennas connected and properly located for proper system performance and operational range. Never operate the system with less than two antennas.
other end. LMR-195 (or equivalent) coaxial cables can satisfactorily be used in lengths up to 10 feet. LMR-400 coaxial cables (or equivalent) can be used at lengths up to 25 feet. Longer RF coaxial cable runs are not recommended due to signal attenuation in the cable. Install the base station in a convenient location and use the Tempest Remote Transceiver connected with CAT 5 cable and RJ-45 connectors to position antennas in the most suitable locations.
Use optional directional antennas to improve system performance and operational range. A directional antenna focuses the RF signal into a smaller area. When the beltstation is located within this focused area of energy it will have a more powerful signal which will improve range. Only use approved antennas. Unauthorized antennas may be illegal.
Configure the Base Station Base station settings can be configured in two ways: from the base station menu or with the Computer interface called “T-Desk” via a LAN connection. While many functions are available through both methods, certain features may only be available through the base station. Using the Front Panel Controls The Tempest base station can be configured depending on user preferences and the tasks to be accomplished.
In Menu Mode pressing one of the five numbered buttons selects the menu item with the corresponding number from the current list of displayed menu items. This action produces the same result as scrolling with the Volume control to the desired menu item and pressing Enter or the Volume control. To view and select additional menu items, rotate the scroll knob and press Enter to select. A complete menu list is available beginning on page 60.
Selecting a Frequency Band The Tempest 2400 Wireless Intercom System is approved for license free use in most countries. However, due to differences in radio spectrum regulations, some countries require that 2.4GHz equipment limit or adjust its RF spectrum operation. Always determine if there are country specific frequency restrictions that apply and select the required frequency band as described below.
Network Number and Lockout Key The Network Number determines the RF frequency hopping pattern for the base station and its beltstations. This is a key operational parameter and is represented by a number between 0 and 63. The Lockout Key prevents systems with the same Network Number from trying to communicate with each other and is represented by a number between 0 and 255.
Set Display Mode to Static or Dynamic The Static or Dynamic selection only affects the order that the base station LCD Operational screen displays beltstation information. “Static” will be the preferred choice for users who want to ensure that a beltstation that is logged in will always appear in the same location (slot) on the base station display and are using only one base station. “Dynamic” is the default setting.
Base Station Headset Connection and Controls The base station headset connection is a functional user communication point, and may also be used for setup and troubleshooting. The Front Panel Headset can communicate on any one of the four intercom channels. Controls for this headset are located just to the right of the connector, and in the Menu on the base station Settings screen. The front panel headset connector is a 4-PIN XLR male. A compatible headset must be provided by the user.
Front Panel Lock The Front Panel Lock function is intended to minimize the probability of unintentional adjustments to the system. Press MENU, select “Base Station Settings”, select “Front Panel Lock”, press 1 or ENTER to select “Lock”. Press MENU to exit to the main Operational screen. The buttons and knobs on the front of the base station will not function until unlocked, except the power switch will power the unit off. When the base station is powered on it is always unlocked.
GPO Relay Contacts Tempest Wireless provides six General Purpose Output (GPO) contact closures. These GPO contact closures can be used for interfacing with other external devices. The SA (Stage Announce) Relay and the five GPO relays, one for each beltstation, are available through the DB-15 Relay Connector on the back of the Tempest base station. These relays can be triggered from the wireless beltstations. The Stage Announce Relay function in the Tempest base station is activated by the STAGE button.
Auxiliary Input/Output Auxiliary IN can be used to bring program or other audio into the Tempest base station. Audio supplied to the Aux IN Connector can be assigned to any combination of the four intercom channels with individual volumes for each channel at the “Aux In/Out Assignment/Level” menu. Audio from the Aux IN port is routed only to wireless users and is not routed out to the hardwired system.
Reset Memory There are two options to reset memory: Restore Factory Default and Clear memory. Restore Factory Default This option will restore all settings to factory defaults except Pairings and names. Be aware that restoring factory defaults will have an immediate effect on volume, sidetone, relay selection, Aux In/Out levels, hardwired intercom levels, and Shared Slot settings, among others.
Wired Intercom Interface to the Base Station Each of Tempest’s four wireled intercom channels can interface with a 4-Wire matrix intercom or a 2-Wire party-line intercom. Tempest supports a 4-Wire intercom interface to most major digital matrix intercom systems and other intercom 4-Wire devices. Tempest also interfaces with 2-Wire intercom systems including Clear-Com, RTS, and AudioCom (Bal) systems, as well as compatible brands.
Controls The two 2-Wire Intercom Type Select Switches determine the type of 2-Wire intercom that may be connected to the corresponding 2-Wire connectors on the rear panel of the base station. Clear-Com, RTS, or Balanced (AudioCom) can be selected. These switches only affect 2-Wire operation and do not control 4-Wire operation. The CHAN A/B switch selects the 2-Wire system type for both the A and the B intercom channels.
4-Wire (Matrix) Intercom Interface 4-Wire intercom systems use two pairs of wires to carry one full duplex channel of intercom audio - one pair for send and the second pair for receive. In addition to intercom audio, most systems have separate data lines that carry system data from the matrix to the remote devices. The Tempest 4-Wire connection is an audio-only interface to 4-Wire systems. Data can be present on the input cable but no data is utilized in the Tempest base station.
2-Wire (Party-Line) Interface 2-Wire party-line intercom systems carry one or two (depending on the system type) channels of full duplex intercom audio plus system power and other information on a single XLR-3M cable (2 wires and a ground). Each 2-Wire intercom type has a different wiring scheme and unique line characteristics. It is imperative to have the rear panel connections and the front panel settings adjusted correctly for audio to pass correctly between the systems.
station DSP monitors the echo and adjusts the line characteristics (Resistance and Capacitance) to optimize the interface to the external 2-Wire system. When Auto-Null is initiated, all of the functions of the base station including communication are interrupted. The Auto-Null process takes approximately 10 seconds. Intercom levels may need to be adjusted after the 2-Wire intercom lines have been nulled.
Auto-Null Procedure Turn off all TALK buttons on both the wired and wireless systems. Since Tempest monitors a self generated tone to adjust the Null characteristics, any sounds entering through either the wired or wireless intercom systems will interfere with the nulling process.
Other Causes of Echo Please be aware that echo can be cause by several sources. A type of echo referred to as acoustic echo can be caused by another user’s headset, but is inaudible to that user. Have other users turn off their TALK button and determine if the echo stops. Acoustic echo is minimized by software resident in each beltstation. Acoustic echo may be mitigated by decreasing the Mic gain, sidetone or volume on the headset causing the echo.
2-Wire Wiring Schemes Wiring schemes vary and it is important to ensure that the cables are wired correctly for proper system operation. When Tempest is configured for a particular manufacturer’s system, Tempest routes the signal to internal circuitry that conforms to the requirements of that system. The 3-pin XLR connectors on the back of the Tempest base station can have very different characteristics depending on the setting of the slide switches, as can be seen in the table below.
Connecting Multiple Base Stations 2-W Audio links Accu-Sync Tempest base stations may be used together to form large wireless systems, and may include external wired intercom systems. Intercom audio for any or all channels can be linked across multiple base stations. Audio from one base station can be passed via a 2-Wire, wired connection to another base station if they are to share a single channel of audio. Through this method many complex combinations of intercom channels can be achieved.
Steps to Configure a Multiple Base Station System • • • • • • • Locate and configure antennas to minimize RF interference. Make Accu-Sync connections. Confirm BaseSync “ON”. Make 2-Wire Connections. Configure for the appropriate 2-Wire connections. Null each base station. Adjust IN/OUT levels if necessary. Audio Connections for Multiple Base Stations When using multiple Tempest base stations it is often desirable to share the same communication channels across some or all base stations.
section in this manual for more information about connecting to external wired intercom systems. When using an external 2-Wire hardwired connection, only channels that are connected to a wired intercom will be able to share audio between base stations.
Accu-Sync Three Base Stations Accu-Synced Accu-Sync provides a common timing signal between connected base stations. This signal ensures that transmission cycles for all Accu-Synced base stations occur simultaneously. This synchronized transmission eliminates the negative RF effect called desensing. See the following section, “Special RF Considerations for Multiple base stations”, for more information on connecting multiple base stations.
Master Mode Master Mode is a Tempest base station function that allows multiple base stations to share audio without the presence of an external hardwired intercom system power supply. Master Mode provides the necessary system termination to the 2-Wire hybrid circuitry in each of the Tempest base stations so that common audio transfer can take place. Each base station in a linked system provides its own power for audio. Any combination of channels may be linked, from just one channel to all four channels.
Special RF Considerations with Multiple Base Stations Whenever multiple Tempest base stations are operated together in close proximity, special consideration must be taken to ensure proper system operation and maximize operational range. See the Antenna Location section on page 24 of this manual for more information on antenna placement.
Multi-System Tempest Technology Tempest is a digital, frequency hopping spread spectrum (FHSS) radio device. Using 80 MHz of spectrum in the 2.4GHz ISM frequency band, Tempest changes frequency (hops) 200 times per second, following one of 64 hopping patterns (Tempest Network Numbers 0 – 63). The hopping pattern determines the order in which frequencies will be utilized. Each hopping pattern has the same frequencies as all other hopping patterns; the only difference is the order of use.
Factors that affect the maximum number of systems that may be collocated in any given location include: • • • • • • • • The existence and extent of harmful interference caused by in-band external radiators. Number of base stations. Number of beltstations per base station. Whether or not Accu-Sync is being employed. Physical location of base station antennas (either on base stations or on Transceivers). Physical location of the beltstations. Specific hopping patterns selected.
