California-based Henry Engineering is doing what it does best: making nifty utility tools for broadcasters.

The latest are the AES DigiSwitch 3X1 switcher and Superelay II.

The AES DigiSwitch 3X1 is a switcher for AES digital audio signals. It can select up to three AES sources, one of which is selected to be sent to the output. Users can control the switcher via front-panel pushbuttons or remotely with any GPI contact closure. It uses passive relay switching to keep the AES stream bit-accurate with no added delay or latency.

An updated version of Henry’s Superelay, Superelay II is now compatible with LED “on the air” warning lights. It features a DC tally light output that provides up to 300 mA of current. The tally light can “sink” up to 1 amp of current for use with LED lights that require more than 300 mA. Both the AC and DC tally outputs can be used simultaneously. The Superelay II features a built-in flasher.

The ASI5811 adds a low-noise microphone preamp with a software adjustable gain.

Both analog and AES/EBU interfaces are standard on the ASI581x cards. AudioScience says that the analog interface is balanced and uses 24-bit oversampling converters to deliver more than 100 dB of dynamic range with THD+N better than 0.002 percent at sample rates from 32 kHz to 192 kHz. In addition, the AES/EBU input features a hardware-based sample rate converter with a range of 32 to 192 kHz.

The ASI5811’s balanced microphone input is designed to work with professional studio microphones requiring 48 V phantom power. Gain is adjustable from 20 dB to 60 dB. Processing effects for the ASI5811’s 32-bit floating point DSP include a compressor/limiter/expander, and a three-band parametric equalizer.

Each has SoundGuard technology to prevent damage from lightning strikes and voltage surges.

The cards are Windows 7-, 10- and Server-compatible, along with Linux-compatible. Both are compatible with AudioScience’s Multi-Rate Mixing technology for playback, recording and mixing. They will ship with XLR breakout cables.

The card is suitable for broadcast applications that do not require onboard audio compression, such as production. The microphone preamp allows you to create a low-cost recording studio for producing spots and promos.

Transmitter and support equipment manufacturer Bext says that cross-coupling combiners are designed to maximize performance by allowing users to combine closely-spaced frequencies with excellent separation while minimizing insertion loss.

It says that in standard designed-combiners the traditional method used is to combine closely-spaced frequencies is by using a high number of RF filters, which has the undesired side effects of critical tuning, high insertion loss, bulky size and heavy weight due to the extensive number of RF filters necessary.

Bext says the cross-coupling combiner design in its new series of FM combiners accomplishes better performance by the use of an additional out-of-phase coupling which, when properly designed, creates a sharp cutoff without generating high insertion losses, or needing a more limited number of RF filters when compared to standard RF combiners. By using this design, Bext is able to offer combiners capable of putting two or more stations on the same antenna with good isolation among the transmitters, even when the RF spacing between them is as close as 400 kHz.

Processor maker DaySequerra is upgrading its series of TimeLock HD Radio diversity delay processors.

A release explains: “The original DaySequerra TimeLock algorithm, used in the M4 and M4.2 products, measures the time alignment of the MPS and HD1 streams with accuracy to one audio sample. The company’s new TimeLock algorithm maintains this precision with the added capability of working under the most adverse conditions, including situations where an FM station is operating in mono on the legacy analog side and in stereo on the HD Radio side.”

Series 2 of the M4 TimeLock extends delay capability to almost double that of the first series, reaching ±7 seconds. It has also beefed up SNMP capabilities for improved monitoring. The M4 TimeLock Series 2 and M4 TimeLock DDC Series 2 are compatible with Omnia, Orban and Wheatstone processors and the GatesAir HDE200 exporter and Nautel Exporter Plus.

President David Day said, “Proper synchronization is critical to ensure the best HD listener experience. Shifts in synchronization can occur at any time.”

Dielectric has new products to please both low- and high-power broadcasters.

The DCR-U (shown) is aimed at the higher-power broadcasters while the DCP-K is for the lower range.

The company says, “The DCR-U is a broadband, circularly polarized ring antenna that minimizes tower footprint while doubling capacity. Its full bandwidth and high-power design characteristics — notably a pressurized tap point and 4-inch balun — support capacity and high-voltage requirements for multi-station operations.” It says the high-voltage protections are especially important for handling the voltage peaks that come with passing multiple analog FM and/or HD Radio stations through the same antenna.

The DCP-K is a broadband, circularly polarized panel antenna. It “reduces the number of cables required in the feed system by half. Instead of using the traditional hybrid feed system and dual-input panels, the DCP-K design incorporates a single input directly into the balun — thus reducing feed line count and connections, which equates to increased reliability.”

In addition, Dielectric says it will introduce an “innovative field-tunable, FM two-channel combiner that eliminates various traditional components from the design. This includes the absence of coaxial Tee junctions, as well as the associated coaxial line and elbows.”

Dielectric Senior Engineer Derek Small said, “Traditionally, a Tee junction, a pair of delay lines and filters are used to multiplex two channels. By removing the Tee and delay lines, we’ve reduced the combiner footprint for space-limited sites and improved efficiency.” He said the tunable common case design also protects a broadcaster’s investment in the event of a frequency change, allowing the station to use the same infrastructure instead of replacing filters and line.

Orban’s Optimod-PC 5501e is a PCIe card-based FM audio processor designed for work with Windows computers. The company says that it provides the functionality of its Optimod-FM 5500.

Features include two-band and five-band processing, a stereo encoder with Orban’s Half-Cosine Interpolation composite limiter and a low-latency monitor output.

Dedicated on-chip DSP chips relieve the CPU of the heavy lifting.

Using an Orban OptiEXP PCIe expansion chassis, a single computer can shepherd as many as eight 5501e cards.

Both left and right analog and AES3 digital inputs and outputs are available. There two analog composite outputs and two analog SCA inputs plus two sync inputs: AES11 sync and word clock/10 MHz.

Orban says the card can also function as a standard Windows sound card, providing “a recording input and playback output, so it can accept a left/right audio input and emit a processed L/R output through the normal Windows Sound mechanism.” For example, a 5501e can accept the output of playout software that runs on the same computer. “Moreover, integration with Windows Sound allows the 5501e to be interfaced to an audio over IP distribution system using an Ethernet port and audio-over-IP distribution driver on the host computer.”

The 5501e can be controlled remotely and multiple cards can be monitored across a network.
