3.5mm Audio Input Selection in a RealPresence OTX Studio System

You can enable 3.5mm audio input from the RealPresence Group Series 3.5mm audio port using the
RealPresence OTX Studio web interface. 3.5mm audio input is only active under the following conditions.
3.5 mm audio input is then heard from the RealPresence Group system speakers and from all far-end
sites.
• The RealPresence Group system is in an active call.
• Content sharing is active.
• HDMI or VGA video input is active.
When audio is part of active HDMI or VGA content, the 3.5mm audio input mixes in with the HDMI
or VGA audio input.

Set Up Audio Meters

Audio meters measure the strength of audio signals from content audio and recording outputs (HDMI1,
HDMI2, HDMI3, component, and Recording Out).
The Audio Meters indicate peak signal levels. Set signal levels so that you see peaks between +3dB and
+7dB with normal speech and program material. Occasional peaks of +12dB to +16dB with loud transient
noises are considered acceptable. A meter reading of +20dB corresponds to 0dBFS in the RealPresence
ITP system audio. A signal at this level is likely clipping the audio system.
Meters function only when the associated input is enabled. Currently, the microphone meters function is
only available from the SoundStructure Studio software.
