INOVONICS PRESENTS HD RADIO FIX

HD Radio receivers are hybrid-mode radios. They grab and play the analog channel, then cross-fade to digital reception once that signal has been locked in. HD Radio encoding and decoding takes about 8 seconds. This means that the analog channel must be delayed by a corresponding time interval to be in sync with the digital program signal at the receiver output.

Inovonics says that from the inception of HD Radio, keeping the analog and digital programs synchronized has been a major problem. Responsibility for correcting timing errors falls on the broadcaster.

The Justin 808 from Inovonics serves this need; it picks up the FM hybrid broadcast off air, as it’s received by listeners. A correlation algorithm constantly checks for timing differences between the analog and digital program channels, and an additional program buffer adds to or subtracts from the primary diversity delay timing to maintain sync within one 44.1 kHz sampling period, or 22.6 microseconds.

The Justin 808 normally is placed directly ahead of the HD exciter, following audio processing for the HD channel. But it could be placed in the AES digital audio path to the FM stereo generator/exciter if a particular installation dictates. Since time can’t be made to run backward, the fixed primary diversity delay is offset by a small amount so that its audio buffer can make up any difference, plus or minus.

The box also monitors the phase and the level of the audio programs. It can reverse an out-of-phase condition and match RMS. loudness. Its Web interface has SMTP support and enables remote control with level metering. Alarms for carrier and audio loss are dispatched by SMS text or email messaging, and the unit offers time-correction logging presented by graphic display.

BW’S TR300 V2 IS A MULTI-FEATURED TRANSLATOR

BW Broadcast says that its TR300 V2 is the only single-box FM translator.

The TR300 V2 is a versatile box since it can be used as a standalone transmitter complete with analog, digital and MPX inputs. Its built-in four-band DSP audio processor and stereo generator will ensure a competitive signal.

Using a built-in BW Broadcast receiver the TR300 V2 can pull in weak signals. Combined with a low-distortion modulator, difficult translator sites should broadcast a clear signal.

Intelligent email alarms, SNMP, Telnet, UDP and local SD card logging keep users updated with how the translator is doing and will let them know if it needs attention. A front-panel LED screen provides local control while a remote control app allows users access and control from wherever there they are, even if using a smartphone.

Tool-free dual slide-in hot-swappable power supplies will keep the TR300 V2 on air if one of the power supplies falls foul of a lightning strike or power supply failure.

AXIA FUSES CONSOLE EXPERIENCE

Axia highlights the Fusion AoIP console. It features anodized extruded aluminum construction and frame sizes from 8 to 40 channels.

Laser-etched panel markings are used on modules; Axia says they won’t rub, chip or fade. Side-loading faders protect against internal grime buildup, and avionics-grade LED backlit switches rated to 5 million operations are used.

Each fader features an OLED display at the top of the console to provide source, confidence metering and other critical information. Rotary encoders below each display allow rapid source selection and parameter adjustment, including internal Omnia microphone processing with compression, de-essing, expansion, EQ and other functions.

Optional call handling modules and an integrated dialing keypad put control of codecs and phone lines at the user’s fingertips. Controls for external profanity delays (such as the 25-Seven Program Delay Manager) are standard.

Fusion automatically configures mix-minus on the fly, with dedicated talkback buttons on each fader for sources like codecs and telephone hybrids. Integrated IFB capabilities allow users to talk down phone or codec lines, to host and guest headphone feeds or add intercom panels to form a facility-wide intercom system.

In addition to the phone bus, Fusion provides added mixing capacity with four main stereo program outputs, plus four stereo aux sends, two aux returns and a dedicated Record bus for off-air recording. Fusion supports mixing in 5.1 Surround, with synchronized stereo upmix/downmix capabilities.

There’s a dedicated “record mode” key that assigns mics, phones, or any other sources to a utility bus and can start the recording device automatically.

A Web interface allows remote configuration, management and diagnostics. The console can also be controlled using Axia SoftSurface for Windows.

GATESAIR ENHANCES VISTAMAX IP NETWORK

GatesAir has extended networking capabilities of its VistaMax portfolio with VMXpress IP, an AES67-compliant audio and logic device that establishes an audio over IP gateway for radio studios.

VMXpress IP provides interoperability across the studio and signal transport architecture through an open, standards-based foundation, GatesAir says, taking advantage of the non-proprietary nature of ALC NetworX’s Ravenna networking. It simplifies connectivity with audio processors, satellite receivers, phone systems and studio support equipment including program delays. With GatesAir’s network-based studio networking architecture at the core, it says, Ravenna’s networking provides low-latency distribution and signal transparency.

Beyond the studio, VMXpress IP extends networking to other IP transport equipment, including GatesAir Intraplex IP Link codecs, for low-latency audio contribution and distribution. This expands connectivity to transmitter facilities (STL), live remote broadcast sites and the Internet for streaming content to other studios and the Web. The company says limitations of AES and analog connectivity are eliminated, leveraging intelligent networking with IP transport systems by using AES67 over the local Ethernet.

GatesAir says this offering continues its strategy of using single network-based connections (Cat-5/6) to move hundreds of audio and data signals across a multipoint network, ensuring a clean studio design that is easy to deploy, operate and scale as requirements evolve.
