Sony has announced a new XLR module for the A7S, the XLR-K2M. The device is smaller and more affordable than the current XLR-K1M XLR adaptor and the the hot shoe cable, alleviating the requirement for an additional cold shoe mount. Matt Allard from News Shooter caught up with Sony at IBC with a pre-production model of the currently un-named audio adaptor: The previous XLR-K1M adaptor is great, opening up more professional audio solutions for Sony cameras like the A7S. However, the adaptor is only connectable via a hot shoe cable, the module itself also requires an additional cold shoe mount, meaning a rig or arm is required if you want the XLR peripherals. This isn’t such a bad thing when rigging up the Sony A7S, however the beauty of the camera is that it’s small and discreet, traits not usually shared by a rigged up camera setup. The new adaptor module removes the cable, you simply attach the device directly to the camera. There’s certainly situations where both XLR adaptors would have use, Sony has foreseen this and will continue to sell the XLR-K1M adaptor when the new one ships; it would’ve been nice to see a new device replace it, with a removable cable so that you can choose according to setup, instead you’ll have to be more decisive at the time of purchase (or buy both).Read more

Just bought a GH4 or A7S? Missing those lovely audio features that large sensor camcorders brought back? Check out the DXA-SLR ULTRA, Beachteks latest audio module that offers professional audio features via XLR and 1/4″ jack inputs. The DSLR revolution was both fantastic and problematic. It brought us fantastic image quality (for its time) but created a whole host of issues with audio. The latter was arguably one of the main draws of large sensor camcorders. Despite the industry’s immense advancements with camera technology, we find ourselves in a similar position to that of a few years ago. There’s been a surge in popularity with mirrorless systems (thanks to two specific cameras), bringing us some fantastic features and improvements in image quality (compared to most DSLRs), yet we’re back to square one with poor on-board audio. (Having said that, the preamps on the A7S are much better than on Canon DSLR, as Johnnie discovered on his recent review of the camera.) Manufacturers have listened and learned from last time, both the GH4 and the A7S have their respective audio modules that provide greater audio options, yet both are expensive, and the GH4 YAGH interface specifically has a very poor form factor and tricky power options. The DXA-SLR ULTRA is a third party solution for audio, which will no doubt be popular with owners of the new GH4 and A7S cameras, as well as many other XLR-lacking DSLR and mirrorless systems. The DXA-SLR ULTRA is designed to sit under your camera (much like a battery grip) and works inline with the 3.5mm input on your camera and professional audio equipment such as shot gun mics, wireless kits and mixers. It negates the need to record audio separately, offering two audio inputs that double up as both XLR and 1/4″ jack. Each channel is independently adjustable, and along with the monitor volume is controllable via a large analog knob. Other features include independent limiters for each channel, phantom power, low-noise preamplifiers for better audio recording and gain & mic/line switches for greater versatility with various audio formats. Beachtek has released a host of similar devices over the years, a brand new feature of the DXA-SLR ULTRA is the detachable 15mm rod mount. The rods supplied with the device are threaded on both ends, so providing Beachtek haven’t been obstructive we should be able to use any threaded 15mm rod accessories. Whilst this won’t fix the issue of poor inbuilt pre-amps in your XLR-lacking camera, it will give me much greater control over the audio going in, as well as proper audio monitoring both coming into the device, and being recorded to the camera. Here’s a list of the key feature of the DXA-SLR ULTRA Detachable 15mm rod support base. Includes two threaded 3″ rods 3.5mm input to loop back from camera for playback monitoring Built-in headphone amplifier with volume control and 3.5 mm phone jack Switchable 12V/OFF/48V phantom power for both channels Built-in limiters prevent distortion from overly hot inputs High/low gain setting for each channel and MIC/LINE switches Easily replaceable 9-volt battery and low battery indicator Transformer-balanced inputs for isolation and enhanced circuit protection Sturdy die-cast aluminum enclosureRead more
