How Did AusCam Score It? By David Hague

It's amazing how much bad audio there is on video these days, especially in interviews. Too much emphasis is placed on using on-camera mics as against actually aiming for tippy top audio.

To reiterate, viewers will put up with the occasional skippy frame, shaky image or even the odd out of focus, but lousy or stuttery or out of sync audio will never be tolerated and people will turn off. So to fix audio problems, the first thing to do is make sure you are using the right mic for the job, and for interviews, this generally means using a radio transmitter receiver and lapel (also called lavaliere) mic.

Hobbyist videographers and even some top enthusiasts have the misconception that these are horrendously expensive, but this is not necessarily so. Chez Auscam has just taken possession of an Azden WLX-Pro radio mic setup and this retails for less than $250.

And for this price you get a nifty little unit indeed.

Firstly, you get a decent range of up to 76 metres (depending on conditions of course) using FM radio frequencies. And if you are using a couple of these for two interviewees, you have a pair of frequencies to choose from. A shoe mount is built in to attach the receiver to a camera/camcorder but it also possible to attach it to a wall mount.

Why would you do that? Because the WLX-Pro can also double as sender receiver for a PA system for public speaking or in a classroom environment.

The sending unit has a belt clip and the cable is around 1 metre long which is adequate for most jobs. An extender can of course be got if required for just a few dollars from Dick Smith, Jaycar and so on.


Power is supplied by a standard 9v battery in each of the units and the receiver also has provision for an earphone (supplied) or of course you can use your own set of cans (headphones). An adaptor plug is also supplied. The antenna on the receiver extends to around 15 centimetres.

Both units have a single switch for Off/Freq 1/ Freq 2.

In use, audio was very good and quite suitable for live interviews and the like. It would also be more than adequate for shooting say a monologue on stage with a camera on wide to take in the whole stage (think Stephen Fry or Billy Connolly).

Battery life is said to be 10 hours continuous.
