• Verify the connections at the speaker

Excessive noise or distorted audio is heard at the far end

• Locate microphones further away from vent (air flow from the vent should not be

blowing on the microphone)

• Reduce the MIC ADJ trim pot on the front of the SM-02

• Reduce the input level in the codec setup menus to 50% (if available)

• Contact CTG technical support with the manufacturer, revision and model of the

codec

The room sounds extremely "hollow" to the far end

• Reduce the MIC ADJ trim pot on the front of the SM-02

• Contact CTG technical support to review microphone locations and specifications

of the room.

Return (speaker) audio sounds distorted from the far end

• Set the SPEAKER LEVEL knob to the 2:00 position and the volume setting on

the codec to 50%

• Run an audio tone test from the codec or call a different location to ensure a good

audio source

• Disconnect all speakers and test each one individually to isolate a defective

speaker

The far end hears a delayed return echo

• Ensure that the echo cancellation setting of the codec is set to ON if available

• Verify that the LINE OUT A of the SM-02 connects to the specified input by

CTG

• Ensure the SPEAKER LEVEL is set to at least the 2:00 position

• Reduce the speaker volume of the codec and raise slowly back to 50%, the echo

cancellation should converge at the lower levels

• Contact CTG technical support with the make, revision and model of the codec

The voice-tracking camera does not work properly

• Voice tracking cameras use separate microphones located in a set-top system or

near the camera. The CTG audio system will not change or affect in any way

voice tracking performance. A reverberant, "hollow" room will negatively impact

voice-tracking performance.

• If the camera points to a ceiling speaker when the far end speaks, a Y-cable and a

connection to the voice-tracking base should be added. Please refer to the

instructions provided by the manufacturer.
