whether the cables were plugged directly into the BSS case or into the ATEM
Mini. Alternatively, with a high-quality 10 m HDMI cable, the signal flow with all
tested sources was possible without any problems.
Our recommendation:
Based on our consistently positive experience, we recommend using HDMI
quality cables from PURELINK (e.g. PI 1000 series or better). These are available
in different lengths.
Audio connections
Depending on the version, the BSS Case for ATEM Mini contains two audio in-
puts, which are designed either as 3.5 mm stereo jack sockets (Basic) or as 3-pin
XLR sockets (Professional). These inputs are unbalanced stereo inputs, analo-
gous to the inputs on ATEM Mini. This can be used, for example, to import the
audio signal from a PC or smartphone. The professional case includes two au-
dio adapters (3.5 mm stereo jack to 3-pin XLR connector).
Unbalanced stereo inputs
The input sensitivity of the two audio inputs can also be switched to "Mic" (mi-
crophone) in the ATEM software (ATEM Software Control Panel). Nevertheless,
these inputs are not suitable for the direct connection of a symmetrically wired
microphone. In such a case, a (stereo) signal converter (balanced to unbal-
anced) must be connected upstream. Other methods, such as using audio ca-
bles with appropriate jumpers between the pins, can work in individual cases,
but often result in ground loops or other audio artifacts that do not lead to the
desired result.
Feeding the signal from the unbalanced outputs of an upstream mixer is cer-
tainly one of the easiest ways to connect microphones to the ATEM Mini. Our
experience shows that, depending on the internal circuitry of the console, it
may still be necessary to use a (two-channel) line transformer to decouple
ground loops.
Our recommendation:
• Wherever possible, use hi-fi level, unbalanced stereo signals to feed ATEM
Mini's audio inputs.
• Use an upstream mixer with unbalanced outputs to connect microphones.
It may be necessary to use a Y-cable with a 3.5 mm stereo jack (for the basic
case) or one with a 3-pin XLR male connector (for the professional case).

• Depending on the internal circuitry of the mixer, ground loops can still oc-
cur. In this case, please use an appropriate line transformer (galvanic isola-
tion) between the mixer output and the ATEM Mini audio input.
• Alternatively, signal converters (balanced – unbalanced) can be used to di-
rectly feed in individual symmetrical audio sources. These external convert-
ers are available from specialist retailers.
Audio workaround
Many cameras can process symmetrical signals directly (usually recognizable at
the XLR input). The signal is then made available to the ATEM Mini via the HDMI
input. This solution also has the advantage that video and audio from the cam-
era are synchronized. In this video input, the audio signal can be placed firmly
in the stream with the "ON" button on the ATEM Mini, even when switching
sources.
