The company offers monthly payments instead of a single capital purchase expense.
In this review, Doug Irwin rates the DM500 as very useful around the radio station facility.
The handheld tester adds a function to solve a common mic cable problem.
The M2A-FM is based on the M2 HD Radio monitor and shares many of its features.
The .1 release is a free upgrade for all users of True RTA Version 3.
Several units are now available to test analog or digital AM and FM signals.
Beginning in fall 2008, new deliveries of MR-PRO will include extended mass storage RAM capacity of 512MB, allowing storage of 16 times more test signals.
The new software includes a new Starfish display that allows users to see what they are hearing when they are listening in surround sound.
Day Sequerra has updated its M2.0 HD modulation monitor, adding some nice and very useful features. I first reviewed the original M2.0 in Radio magazine in May 2006, and the new M2.2R model is an attractive piece of test equipment that will likely go in your facility where it can be seen by you and others.
When a station changes to AES3 or S/PDIF digital audio, the availability of easy-to-use, rugged and portable test equipment declines greatly.
With analog, engineers know how to measure levels, frequency response and distortion to gauge the audio performance. Unfortunately, digital audio changes all this.
Audemat-Aztec has released software version 1.4 for its Goldeneagle HD monitor. The new release is based partly on input from customers to improve the unit and is available free of charge.
With HD Radio, stations at minimum need to monitor the main channel audio. But there's also multicasting, PAD and funny initials like DAAI and QI that tell volumes about the signal. The big question is how to acquire all of that data.
The computer hard drive is 50 years old this month. Take a look at the IBM RAMAC, which held 5MB of data and was the size of a refrigerator.
Being able to go back and forth easily between different HD Radio streams is educational in terms of processing--and being able to quickly study your competition's HD Radio audio, now that's what radio engineering is all about.
If you had the opportunity to equip yourself anew for the year, which pieces of equipment would make your core list?
When the work takes you outside the studio.
Doug Irwin put the Dscope test set through several tests of his own.
You have seen the TV spots for the latest and greatest products that we just can't live without. Recently there was one that caught the eye of our reviewer. It might have caught your eye as well.
While the basic skills of evaluating system performance are still in place, the tools and the methods used today are changing significantly. Digital signals require analog tools, but you can't neglect the analog elements either.
Radio magazine's annual Product Source, Beyond these walls.
A few engineers believe it is easier to maintain a digital audio chain because they no longer need to deal with the audible effects of ground loops, noise, crosstalk and mismatches typical in some analog signal paths. Wrong!
This interface facilitates making analog audio measurements with an oscilloscope.
Early solid-state audio spectrum instruments provided limited resolution, but the MSD100 offers a bright, easily read display of stereo separation and frequency dispersion.
Most digital equipment is woefuly lacking in its ability to display why it is unhappy. Luckily, the Digilyzer displays things such as lack of data compliance, bad cables or poor signal quality.
