Audio features
Primary audio group — Input and output balanced or unbalanced stereo audio
on 3.5 mm, 5-pole captive screw terminals.
• Audio input gain/attenuation (primary audio group) — Individual input
audio levels can be adjusted so there are no noticeable volume differences
between sources. Users can set the input level of audio gain or attenuation
(-18 dB to +24 dB) via the Ethernet port, any RS-232 port, or the front panel.
Mic audio group — Input mono audio on 3.5 mm, 3-pole captive screw
terminals.
• Audio input gain/attenuation (mic audio group) — Individual input audio
levels can be adjusted so there are no noticeable volume differences between
sources. Users can set the input level of audio gain or attenuation (0 dB
to +80 dB) using the DSP Configurator program or SIS commands and the
Ethernet port or any RS-232 port.
• Phantom power — The switcher can provide +48 VDC phantom power, a
standardized method of providing power to condenser microphones.
• Output two channel mono audio on the primary audio group outputs.
Audio output volume — The audio volume of each output can be displayed and
adjusted through a range of full output to completely silent from the front
panel or under RS-232 or Ethernet control.
Digital signal processor — The powerful, built-in, DSP provides a wide variety
of high-end audio capabilities, including:
• Gain, volume, and trimming
• Balance control
• Filtering
• Dynamic processing
• Feedback suppression
• Delay
• Loudness
• Mic mixing
• Mic ducking
Group masters — Any of the gain, volume, and trim controls in the DSP can be
grouped with other controls of the same type (in the same location in the
audio signal flow) for single-slider control of the entire group.
