BeachTek HD DSLR audio adapters

BeachTek now has two audio boxes for HD DSLRs that take XLR inputs, allow you to adjust levels, and route the result to the DSLR's mini-jack input.

The BeachTek DXA-5DA (pictured top) is a passive adapter, which doesn't have phantom power – you would use it with self-powered condenser microphones or wireless receivers, or as an interface to an audio mixer.

It has two inputs, a level meter, and a "unique AGC Disable feature controls the wild swings of the Auto Gain Control that plague most cameras," which reduces noise during quiet moments of recording so that you can record cleaner audio. It fits under the camera and can also be mounted to a tripod. It is powered by one 9-volt battery and costs about £290.

There is also the BeachTek DXA-SLR, with phantom power. It is similar, but without the little LCD meter display. It has Good/Peak signal indicators that show the ideal input levels at a glance, plus the AGC Disable feature. You can also monitor the playback audio from the camera. It costs about £350.

Also potentially useful is BeachTek's MultiMount 5D ($89), which provides four horizontal cold shoes and one vertical shoe for mounting microphones, wireless receiver, lights, etc. on your DSLR or camcorder. It is made of polycarbonate with metal shoe inserts and has threaded 1/4-inch/20 holes on all shoes for added flexibility. It also has a rubber mounting foot with locking plate for mechanical shock isolation, but it may not be advisable for use with heavier devices, which is why it also comes with an extra foot that provides a firmer mount.
