The SL-2 is an updated model of a previously released range of SuperSlot -based connectors that bring wireless interchannel audio over existing television broadcasts. This new two slot-in radio receiver interchannel audio integration system readily mounts easily to the front panel of any modern 8-series mixer-processor. The integration solution enables manufacturers to build on-board mixing consoles and soundboards with state-of-the-art components and advanced technology. In addition, many of the latest multimedia features are also available on the interchannels. For example, digital video compression is now offered. There is also a wide range of signal sources to choose from.
The most important function for all radio receivers is their ability to capture and transmit audio signals for recording purposes. The most common form of radio interconnects used for this purpose are Cat 6 carriers. However superslot, as advances in the technology have increased, other types of interconnects have been developed, such as SLIP (subscriber line interconnect), SSTP (subscriber store switch) and TDMA (TAB + switching media access). With the development of SLIP, however, the possibilities for wireless audio interconnection has increased as well. The SL-2 had the ability to provide HD voice broadcast capabilities.
With SL-2B, manufacturers can now offer high definition voice broadcast capabilities. They also increase the possibility for HD voice output to work with SSTP and TDMA systems. These features can be combined with various types of converters and power solutions, such as Toshiba proprietary converters and Power Matters TM (Power Matters TM slots). With these solutions, manufacturers can build on-board powered mixers and receivers that incorporate both SSTP and TDMA.
With the use of an RF command transmitter, the RF command receiver can also be enabled with a remote control. This allows the user to monitor all functions from a remote location. For example, the RF command transmitter can be used to control and change video and audio outputs from the input receivers, depending on the needs of the particular application. One example is a hospital setting where a patient is seen but no surgeon is available to operate. Using the RF command transmitters, a technician can activate and deactivate the cathodal cord intercom, or monitor heart-rate monitoring equipment. Since the RF command receiver has a built-in de-clocking mechanism, it can be left on indefinitely while at the same time, transferring data between the user’s computer and hospital server.
The superslot’s RF output capabilities can also support zoned wireless audio channels. A zone is a virtual radio stations that can be assigned to different frequency channels and can be used for indoor or outdoor operations. The superslot has been designed to allow all zoned wireless channels to be enabled and demodulated. If a single frequency is needed for the system, the zoned channels can be omitted in order to maintain compatibility with the other RF elements. The RF signal is sent out as a continuous signal after demodulation, allowing it to travel long distances and to be used in conjunction with zoned channels.
An RF output powered by an SFP or SiFET antenna will work well for the SL-2 slot. The antenna can support both 12 V DC and AC in the receivers and will support SFP single mode, SFP dual mode and SFP optical Ethernet modes. The antenna is also optimized to work well with the SL-2 slot’s duplex function. In this function, both analog and digital signals can be transmitted and received.
Other RF output devices from the superslot include a RF power analyzer, RF isolator, RF modulator and RF spectrometer. All of these RF products operate in single or double wave mode, have separate RF output circuits and can support DC outputs in excess of twelve V. They can be used in applications where additional bandwidth is needed, such as for uplink and downlink. The RF isolator allows for separate channels to be set up for any given radio station and is useful when multiple transmitters and receivers are needing to operate in the same frequency band.
The RF mixer and RF demodulator are useful for creating demodulated and blended RF waveforms for remote control operations. The RF mixer uses a dedicated mixer stage to convert the broadcast waves into lower or higher frequency RF signals and then converts the lower frequency signals to send them to the receiver. The RF modulator is similar to a demodulator only that it produces lower frequency RF signals to enable transmission on another channel. Mixers, receivers, transmitters, and mixers are using in various radio and satellite communications applications to facilitate communication.
