Description
The BeachTek DXA-SLR PRO is a two-channel, active XLR
adapter with built-in preamplifiers for attaching external
microphones and other audio gear 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.
The DXA-SLR PRO uses exceptionally low noise, wide
bandwidth preamplifiers for superb audio. 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 DXA-SLR PRO is very easy to set up and use. It allows you
to connect a wide variety of audio devices including wireless
systems, mixers, sound boards and professional condenser
microphones that require 48 volt phantom power to operate.
The inputs are transformer balanced for isolation and enhanced
circuit protection. Built-in VU Meters makes it easy to verify the
proper input levels at a glance, while the level controls allow you
to adjust the output signal for optimum recording. Built-in fast
acting limiters prevent distortion from overly hot inputs for worry
free operation. The phone jack lets you monitor the audio from
the adapter during recording, or camera during playback.
A unique feature of the DXA-SLR PRO is the ability to control
the wild swings of the Auto Gain Control that plague most
cameras. This dramatically reduces noise during quiet moments
of recording.
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 damaging your hearing.
Always do a test recording and play back the audio to ensure it
is acceptable
DO NOT activate phantom power for dynamic microphones,
condenser microphones that do not operate on phantom power,
wireless receivers, mixing boards or any unbalanced device as
it may cause damage to both the adapter and connecting
device.
Turn off power to adapter before plugging or unplugging any
microphones or equipment to or from the adapter.
