The Bisset Brief: Label those Cables!

By John Bisset on Aug 9, 2017 11:15:00 AM

As I travel throughout the US, I've seen a number of great Axia Livewire+ AES67 AoIP installations, and enjoy sharing some of these concepts with readers.

IP Audio Networking and clearing out analog wiring has been a key theme of late. Clearing unneeded cabling is an essential concern when converting to Livewire+ AES67, and it's crucial to label your Axia Livewire+ AES67 CAT5/6 cabling. Over time, networks grow, and labeling your Ethernet cables ensures the wiring won’t get out of hand.

The Bisset Brief: Cutting the Cord

By John Bisset on Jun 28, 2017 11:30:00 AM

Veldon Leverich is the Director of Engineering for Salem Media’s Sacramento cluster. Veldon recently installed an AXIA IQ 8-fader console with a 6 channel Telephone Expansion Chassis, pictured in figure 1. One of the impressive features of AXIA’s patented AoIP Livewire+ system is the elimination of lots of wire. Livewire+ is really a paradigm shift for engineers – no more distribution amps, endless punch blocks, or even TRS patch bays.

A Visit to the Past and the Present

By John Bisset on Jul 8, 2015 2:00:00 PM

Many Television engineers got their start in radio, and still keep up with happenings in the world of Radio. The staff at WIBW, Channel 13 in Topeka, Kansas, is no exception. My associate from Linear Acoustic, Hal Buttermore, and myself, had the pleasure of speaking to the engineers of SBE Chapter 3, Topeka, Kansas, meeting at the WIBW studios in May. Chief Engineer, Cary Lahnum, led a tour of the facility which included both new and old, including one of the station’s old RCA black and white cameras, with an old remote mixer sitting on top.

Disaster Planning for the Transmitter Site

By John Bisset on Jul 9, 2014 3:47:00 PM

Of all the components of the broadcast facility, the transmitter may be the most important in a disaster. That site can be pressed into service as a combination studio/transmitter location, especially if a backup generator exists. Back in the days of cart machines, we removed a rack of three decks, relocating them to the transmitter, to stay on the air when the studio flooded. It wasn’t the most glorious of 'studios', but we stayed on the air and covered all the spots. Nowadays with backup hard drive systems or even an iPod® for source material, a station can usually stay on the air during a disaster.

Disaster Planning for the Studio

By John Bisset on Jun 11, 2014 1:52:00 PM

Last time, we covered a number of general planning tips in preparation for disasters. When the disaster strikes is not the time to develop a plan. First on our list of suggestions is hardening your studio site. Should the studio site fail, do you have an off-site backup facility?

If not, think remote truck! Should you lose your studio facility, a remote truck can be pressed into service to keep you on the air. Prior to predictable weather emergencies, keep the truck fluids topped off.

By John Bisset on Mar 1, 2014 10:01:00 AM

As engineers exchange the world of single- and two-pair shielded cable for CAT5/6, finding a simpler way to interconnect non-networked gear becomes more important. Of course, you can buy adaptor cables pre-made, but what do you do with the excess cable?
