RovoRx UltraHD HDBaseT Receiver v1.0r1 11 www.aja.com
Audio Level
The RovoCam microphone input is a single ended stereo audio input with a fixed
20dB of gain. The RovoRx has a fixed audio gain of 10dB, giving a system gain of
30dB which will bring a typical microphone output up to line level.
System Ground and Audio
When the RovoCam is used with RovoRx, the power provided by RovoRx
has 1500V isolation from ground, meaning that the RovoCam is electrically
isolated from ground. When RovoCam is used with an external microphone, the
microphone is also isolated from ground, and there will be no noise issues. If you
use the RovoCam microphone input from source equipment which is grounded it
can cause ground loops in the system and unintended noise will be heard on the
microphone input. To correct this, the user can ground the RovoCam camera by
connecting a ground wire to the negative input of the 12V DC power connection.
This will effectively tie the camera to earth ground and eliminate the unwanted
noise.
RovoRx-HDMI Rack Mounting
The RovoRx-HDMI can be mounted to a rack using AJA's optional RMB bracket.
The threaded holes in the case can also be used for mounting without the
bracket, using 1/4 inch 440 thread screws.
RovoRx-HDMI units can also be installed in AJA's DRM frame, but each RovoRx-
HDMI will require its own external power supply (provided). If unused space is
not available in the DRM frame, the power supplies can be tie-wrapped above or
below the frame, provided air flow is not restricted.
