Shure Whiteboard – Rechargeables for Wireless

Shure UK Senior Applications Engineer, Tom Colman explores rechargeable battery options for wireless microphones - moving from standard disposable batteries to modern integrated rechargeables. Read the article below, or scroll down to watch the Whiteboard Video. Wireless microphones and in-ear monitor systems all need power from somewhere. Traditionally, wireless operators use a standard portable cell […]

Shure Whiteboard – Digital Wireless Latency Explained

Shure UK Project Engineer, Stuart Stephens explores digital wireless latency and what causes latency in a digital wireless system. Read the article below, or scroll down to watch the Whiteboard Video. Latency is the amount of time it takes for our signal to journey from input (microphone capsule) to audio output (analogue audio output on […]

Shure Whiteboard – Analogue vs Digital Wireless

In this month’s Shure Whiteboard Session, Shure Senior Applications Engineer, Tom Colman explains some of the basic differences between digital and analogue wireless systems. (Video at the bottom of this article).  For many years, analogue wireless systems ruled the airwaves, but in recent years we’ve seen increasing amounts of digital systems. On the surface, one might […]

Shure Whiteboard – Two Common Causes of RF Interference

When it comes to RF interference, there are two elements (or items if you like) that come up frequently as common culprits – metal and salt water. We’ve written plenty of detail about these major RF enemies before, and the following video should help to add context. In essence, large metal structures (fences, stage rigs, […]

What Are Whitespace Devices? Shure Whiteboard Explains…

Not so long ago Ofcom approved plans for Whitespace Devices to share spectrum with digital TV and wireless microphones. As a relatively new development in the ongoing debate about the future of spectrum, Whitespace Devices are often overlooked or misunderstood. In this week’s whiteboard session, we cover what whitespace devices are, why and where they operate, […]

Shure Whiteboard Session: Antenna Selection & Placement

Like microphones, antennas are transducers, converting energy from one form to another. In the case of transmitting antennas for in-ear monitors, they’re converting current into electromagnetic waves; for wireless microphone systems, they perform the reverse. The size of antenna required is related to the wavelength. For example: in a VHF system operating from say 170 to […]

Shure Whiteboard Session: Visualising the RF Environment

This week’s Shure Whiteboard Session covers visualising the RF landscape. Why would we want to do that? I hear you ask…. The reason for RF visualisation is simple: When setting up our wireless rig, we need to maximise the amount of channels we can have on air and ensure reliable performance by understanding what spectrum […]

Shure Whiteboard Session: Understanding Cables for RF

Welcome back and happy New Year! As we head into 2016, we’re back with another whiteboard session. This week’s topic will answer common questions about cable components for your RF setup. RF cables are an often overlooked aspect of wireless systems. You can have everything else set up perfectly: you’ve got the right kit; you’ve […]

Shure Whiteboard Session: What is Intermodulation?

Welcome back, in this week’s whiteboard session, we’re going to tackle the often misunderstood concept of intermodulation. Intermodulation is a product of two signals interacting with each other while on air simultaneously. It commonly occurs when two signals are in very close proximity to one another, and therefore, any intermodulation need to be avoided with […]

Shure Whiteboard Session: How to Coordinate a Wireless System

Welcome to the fourth instalment of our Shure Whiteboard Sessions, we hope you’re enjoying the new series thus far. In this week’s video, we get stuck into some wireless microphone best practice with our explanation of how to coordinate a wireless system (or frequency coordination as it’s otherwise known). Some basics to consider The first […]

Shure Whiteboard Sessions: What’s happening to UHF

Welcome back to the Shure Whiteboard Sessions. In last week’s episode, we covered the most common parts of spectrum used for the operation of wireless microphones and explained why the UHF bands are the preferred space for professional users. With the latter in mind, today’s episode will explain what’s happening to the UHF space and […]

Shure Whiteboard Sessions: What Spectrum is Right for You?

For radio microphones to work reliably, we need access to clean spectrum – this much is well known and documented. What’s less well known, is which bands of spectrum are best suited to each given application. Unfortunately, we can’t just use any portion of spectrum; and while in theory there’s a lot of spectrum available, the […]
