The DXA-SLR PRO makes it possible
to use professional microphones that require XLR connections. Two
high-quality Neutrik XLR inputs ensure a noise free recording
chain, even for longer distance cable connections.
Each channel offers up to 15dB of gain on its HIGH setting, and 0dB
of gain for more sensitive condenser type microphones.
12 or 48v phantom power can be sent to each channel for phantom
Limiters are an essential feature for recording unpredictable sound
levels, without distortion or clipping. Each of the two channels on
the DXA-SLR PRO feature independent limiters that keep the audio
levels below 0dB to prevent signal overload.
The AGC Disable feature reduces the hiss that normally occurs when
certain HDSLRs record audio during quiet moments. This is
accomplished by delivering an inaudible tone to the camera to force
down the recording level consistently throughout the recording.
This allows you to use the adapter's cleaner preamps for adjusting
the volume of each input. AGC: The camera's Automatic
Gain Control pumps up volume beyond a recording subject, creating
noise. AGC DISABLE: DXA-SLR PRO actively supresses noise.
Lacking a headphone output and level meters, most HDSLRs lack the
basic monitoring capabilities that are standard on pro video
cameras. Recording audio without being able to listen to what the
camera is recording is like shooting without a viewfinder. Several
crucial monitoring features are included in the DXA-SLR PRO to
ensure that audio issues are identified before and during the
Monitoring audio levels is made even easier with the DXA-SLR PRO VU
Meter LCD Screen on the rear of the adapter. The meter is perfectly
positioned in direct line of sight when holding the camera in a
With headphones connected to the adapter and the camera’s A/V
output connected to the adapter, it becomes possible to monitor
audio during and after recording with the flick of a switch.
Every aspect of the DXA-SLR PRO has been designed
with the cinematographer in mind. From the intuitive controls and
high-quality preamps, to the form-fitting ergonomics and a sturdy
aluminium chasis, this is a highly capable HDSLR audio adapter.
The DXA-SLR PRO is designed to conform to the shape of HDSLRs,
resulting in improved ergonomics and a more compact package
