STL

Studio Transmitter Links

Marti STL transmitters and companion receivers form a high-quality, point-to-point radio communications link.

Marti gives you a choice in uncompressed analog STLs. We continue to offer discrete systems utilizing separate transmitters and receivers for left and right channels, as well as composite stereo configurations. Companion subcarrier generator/demodulator pairs are also available.

Available in a wide range of band models, complex systems can be built from basic transmitter/receiver pairs having multiple relays (repeaters), bi-directional (full duplex), and automatic switching standby features.

STL Transmitters

Marti STL transmitters provide the value and features demanded by today’s broadcasters.

Each transmitter is equipped with a wideband power amplifier to produce a radiated RF output power that is adjustable from the front panel up to 30 watts in most bands. Unlike older STL models, the power amplifier combined with a wideband synthesizer means no RF tuning is required.

The internal gain stages are pre-matched for optimum performance and stability across the entire band.

Marti STL transmitters operate on any AC voltage from 110-120 VAC or 220-240 VAC, and feature external 12-15 VDC or 15-30 VDC supply capability and external transmit control.

STL 20C

Frequency-agile Studio-Transmitter Link

The STL 20C is our latest composite STL transmitter. This transmitter replaces the STL 15C. There are a number of changes that were made to make this the price-value leader in composite STL products. The STL 20C is synthesized, frequency agile and utilizes a new RF amplifier, as well as a cooling fan. More power, reliable, cooler and easier to tune – that’s the new STL 20C.

STL 20M

Single-channel Studio-Transmitter Link

The STL 20M is our latest mono STL transmitter. This transmitter replaces the STL 10. There are a number of changes that were made to make this the price-value leader in mono STL products. The STL 20M is synthesized, has a new RF amplifier, as well as a cooling fan. More power, reliable, cooler, and easier to tune – that’s the new STL 20M. Two of these units can be used to build a discrete stereo STL system.

STL Receivers

As part of a paired Marti STL system, the SR 20C and SR 20M receivers exemplify performance and reliability.

Each Marti STL receiver is offered in a wide range of band models.

Complex systems can be built from basic transmitter/receiver pairs by integrating multiple relay (repeater), bi-directional (full duplex) and automatic switching hot standby features.

Marti STL receivers are equipped with a multimeter and meter select switch for the monitoring of signal level, subcarrier level, power supply voltage and program output level parameters.

SR 20C

STL Receiver

The SR 20C is the companion receiver to the STL 20C transmitter. This unit is fully synthesized and can be operated in any frequency within the specified band of operation. The SR 20C is frequency agile and can be programmed easily to any operating frequency in the band of interest.

SR 20M

STL Receiver

The SR 20M is the companion receiver to the STL 20M transmitter. This unit is fully synthesized and can be operated in any frequency within the specified band of operation. The STL 20M is a single frequency receiver, but is fully synthesized for great performance.

RPU

Remote Broadcast

Marti remote pickup transmitters and receivers are reliable year after year and can stand the punishment of time and hostile field conditions. Providing the best value, Marti products are assembled and tested in the USA to meet the rugged demands of today’s broadcasters. Marti RPU equipment can also be used as TSL units, providing return audio links.

RPU Transmitters

Whether you’re looking for a fixed, portable or mobile remote transmitter, Marti RPU transmitters combine unbeatable value with the features and reliability you’ve come to expect from BE.

Marti SRPT 30/40A models are wideband, high-power RPU transmitters designed for reliable high-quality remote broadcast links.

Both models feature synthesizer technology to increase performance and eliminate the need for RF tuning.

SRPT 30

Two-channel RPU Transmitter

This two-channel synthesized RPU transmitter is available in bands from 135 MHz to 965 MHz. The features are similar to the RPT 30, but is wide band so there is no minimum separation of the two frequencies as long as they are within the band selected. This model incorporates the proven synthesizer and RF amplifier technology.

SRPT 40A

Frequency-agile RPU Transmitter

The SRPT 40A is our most powerful RPU transmitter. The synthesizer and RF power amp technology was developed for the composite STL and has been incorporated into the SRPT 40A. Now you can dial the exact frequency for the selected band from the front panel. The SRPT 40A is available in models that cover frequencies from 135 MHz to 965 MHz.

RPU Receivers

Working with their companion transmitters, Marti receivers provide a high-quality synthesized point-to-point communications link for remote broadcast applications.

Each receiver is offered in a wide range of band models for maximum flexibility.

Each can be portable or rack-mounted and can operate on AC or DC power, and features front panel squelch control and front panel signal attenuation control to minimize IMD products.

SR 30

Two-channel RPU Receiver

The SR 30 is the companion RPU receiver to the SRPT 30 RPU transmitter. This two-channel receiver can be operated anywhere within its specified operating bandNo minimum spacing requirement within the band of operation.

SR 40A

Frequency-agile RPU Receiver

The SR 40A is the companion RPU receiver to the SRPT 40A RPU transmitter. This receiver is fully synthesized and frequency agile. It can be operated on any frequency within its specified band through the front panel controls and there are no minimum spacing requirements with the operating band. This frequency agile RPU receiver is available in bands from 135 to 965 MHz.
