In the following pages you will find a complete list of the system settings. The examples shows either the default value or an example of a value.

All specifications are subject to change without prior notice.

We recommend you visit the TANDBERG web site regularly for updated versions of the manual. Go to: http://www.tandberg.com/docs

Audio Input Line [1..2] LoopSuppression: <Off>

Loop suppression detects whether a delayed signal loop is present from an audio Line output to an audio Line input on the codec. If a loop is detected, this unwanted feedback is suppressed.

On: Set to On to activate Loop Suppression.

Off: Set to Off to deactivate Loop Suppression. Note! Codec C60 does currently not support Loop Suppression, hence Loop Suppression can be set to Off only.

Example: Audio Input Line 1 LoopSuppression: Off

The Audio settings

Audio Input HDMI [2..2] Level:<-24..0>

Defines the input level of HDMI input 2 in steps of 1dB from -24 dB to 0 dB.

See the Audio Level tables in the Codec C60 System Integrators Guide for a complete overview of the menu values represented in dB.

Range: -24 to 0 dB

Example: Audio Input HDMI 3 Level: 0

Audio Input HDMI [2..2] Mode: <On/Off>

Determines whether or not the two audio channels on the HDMI 2 input should be enabled. On: Set to On to enable the audio channels on the HDMI 2 input.

Off: Set to Off to disable the audio channels on the HDMI 2 input.

Example: Audio Input HDMI 2 Mode: On

Audio Input Line [1..2] Channel: <Left/Right/Mono>

Defines whether the Audio Line input is a mono signal or part of a multichannel signal. Left: The Audio Line input signal is the left channel of a stereo signal.

Right: The Audio Line input signal is the right channel of a stereo signal.

Mono: The Audio Line input signal is a mono signal.

Example: Audio Input 1 Channel: Left

Audio Input Line [1..2] Level: <0..24>

Defines the input level of each Line input in steps of 1dB from 0dB to 24 dB. Addresses the specific Audio Line input.

See the Audio Level tabels in the Codec C60 System Integrators Guide for a complete overview of the menu values represented in dB.

Range: 0 to 24 dB

Example: Audio Input Line 1 Level: 10

Audio Input Line [1..2] Mode: <On/Off>

Determines whether or not an Audio Line input is enabled. Addresses the specific Audio Line input. On: Set to On to enable the Audio Line input.

Off: Set to Off to disable the Audio Line input.

Example: Audio Input Line 1 Mode: On

Audio Input Microphone [1..4] EchoControl Mode: <On/Off>

The echo canceller continuously adjusts itself to the audio characteristics of the room and compensate for any changes it detects in the audio environment. If the changes in the audio conditions are very significant the echo canceller may take a second or two to re-adjust. Addresses the specific microphone.

On: Echo Control is normally set to On to prevent the far end from hearing their own audio. Once selected, echo cancellation is active at all times.

Off: Echo Control should be switched Off if external echo cancellation or playback equipment is used.

Example: Audio Input Microphone 1 EchoControl Mode: On

Audio Input Microphone [1..4] EchoControl NoiseReduction: <On/Off>

The system has a built-in noise reduction which reduces constant background noise (e.g. noise from air- conditioning systems, cooling fans etc.). In addition, a high pass filter (Humfilter) reduces very low frequency noise. Requires the Echo Control Mode to be enabled for the specified microphone. Addresses the specific microphone.

On: The Noice Reduction should be set to On in the presence of low frequency noise.

Off: Turns Noise Reduction Off for the specified microphone input.

Example: Audio Input Microphone 1 EchoControl NoiseReduction: On

Audio Input Microphone [1..4] Level: <0..24>

Defines the input level of each microphone in steps of 1dB from -24 dB to 0 dB. Addresses the specific microphone.

See the Audio Level tables in the Codec C60 System Integrators Guide for a complete overview of the menu values represented in dB.

Range: 0 to 24 dB

Example: Audio Input Microphone 1 Level: 14
