5.2 Connecting an Audio Output Device
Knowledge of audio interfaces on the endpoint and the various types of audio interfaces can
help in quickly and correctly connecting an audio output device to an audio output interface
on the endpoint.
5.2.1 Connecting a Speaker
Connect the AUDIO OUTPUT RCA L/R port and the audio input port of a display device
using an audio cable. In this way, the endpoint can use the built-in speaker of the display
device (for example, a television which is usually equipped with a speaker) or it can be
connected to an external speaker system, wherein the volume can be increased and a better
audio effect can be obtained.
Use an audio cable to connect the AUDIO OUTPUT L/SPDIF port to a speaker to provide
high-fidelity audio quality.
5.2.2 Placing an External Speaker
If the endpoint is connected to an external speaker, correctly placing the speaker helps to
achieve the expected audio quality.
Note the following when placing an external speaker:
If you are using a unidirectional microphone, the speaker and microphone must not face
one another.
If you are using an omnidirectional microphone, the distance between the speaker and
microphone must be more than 1 meter.
5.2.3 Adjusting the Speaker Volume
Press to increase the volume or to decrease the volume. The adjustment affects the
volume heard only at the local site.
5.3 Connecting a Tuning Console
If a conference room requires multiple microphones or already has a tuning console for
controlling microphones, you can connect the tuning console to the endpoint as the endpoint's
audio input source.
Connect the output interface of the tuning console to the RCA L/R audio input interface of the
endpoint using an RCA audio cable.
5.4 Adjusting Audio Effects
You can adjust the audio effects, such as the audio input, sound effect, and volume.
