Description
The Beachtek DXA-SLR PURE is a two-channel, passive audio adapter
for connecting amplified signals from a wireless mic or a mixing board to
any DSLR camera that has a built-in mic jack. It can also be used with
any camcorder or other audio recording device that has a mic jack. Note
that it is not designed to connect directly to unamplified microphones.
The DXA-SLR PURE uses exceptionally low noise, wide bandwidth,
balancing transformers for pure, clean audio with no electronics to get in
the way. This allows you to record high quality audio directly to the
camera which will always be in sync with the video. Direct audio
recording eliminates the need to have a separate audio recording device
and syncing the audio in post editing.
The transformer balanced inputs provide electrical isolation from the
camera for protection and also to reduce the possibility of ground loop
noise. Built-in VU meters makes it easy to verify the proper signal levels
at a glance, while the level controls allow you to adjust the output signal
for optimum recording. The phone jack lets you monitor the audio from
the adapter during recording, or camera during playback.
The adapter mounts to the bottom of the camera and can also be
mounted to any standard tripod.
Warnings
Ensure that the VOLUME control is set low to avoid excessively loud
audio from damaging your hearing.
Always do a test recording and play back the audio to ensure it is
acceptable.
This adapter does not have a preamplifier to increase the signal levels
from the inputs – the output level will only be as strong as the input level.
It is not designed to be connected directly with most microphones as it
will most likely result in a too low an output level for optimum
performance with DSLR cameras. For this application you should use
one of our active adapters which have built-in preamplifiers.

Before You Begin
1) These instructions refer to the use of this adapter with Canon
DSLR cameras unless otherwise noted.
2) Do a few test recordings and check playback on the camera to
ensure that the audio is captured as expected. Most cameras do
not have a headphone jack to monitor what is being recorded.
3) Some older Nikon cameras have a very sensitive microphone input
and require a special 25dB padded output cable from the adapter.
Please contact us for details.
4) Some Sony wireless mics have very low output levels which will
not give you good results without some form or preamplification.
5) Panasonic Lumix GH1 and GH2 require a special 2.5mm mic
cable which is available from our Online Store.
Supplied Accessories
3.5mm to 3.5mm output cable
AV Cable for playback monitoring
