Using Audio Level Meters (Clear-Vu ®)

You can apply Clear-Vu ® audio level meters to conferences and four-wire ports in real-time with Dynam-EC. The meter setups can be saved to the project (layout) file (*.ccr). Audio level meters can be added to four-wire ports in the palette in a reduced format.

This facility normally requires at least one LMC-64 audio metering card to be fitted to the matrix.

You can set up a single audio meter without an LMC-64 card in Settings > Associated Meter Port. For more information, see Setting up an Associated Meter Port.

You can configure the number of audio meters provided by an LMC-64 card to 16, 32, 48 or 64 meters in EHX. The same audio meter data can be used by multiple Dynam-EC clients, which means that multiple assignments of the same audio meter will not use up additional meters.

The total number of available meters:

• Is displayed in Dynam-EC within the red circle of the meter.

• Updated on all Dynam-EC clients, every time a meter is applied.

You can still assign meters to a four-wire or conference when zero free meters are reported, provided that the four-wire or conference:

• Already has a meter assigned to it.

• The audio level data is already being broadcast.

In this case a new meter does not need to be assigned to the target.

However, if an attempt is made to assign a meter that requires an additional meter and no free meters are available, the following message is displayed:

There were not enough free meters to fulfil the request.

Because the audio level information is broadcast by the LMC-64 cards, the Dynam-EC clients must be on the same network as the LMC-64 cards (unless switches or routers are configured to forward the broadcast data between networks).

Dynam-EC does not require the IP address of the LMC-64 card.

Warning: The use of meters consumes PC system resources. If extensive use is being made of audio level metering, a minimum specification PC may not be suitable (see System Requirements.

Meter functions	Comments / Description
Input meter	Input meters display the audio level into the matrix from a port, after input level adjustment has been applied.
Output meter	Output meters display the audio output level from the matrix to a port after output level adjustment has been applied.
Conference meter	Conference meters display the mixed audio level. Conference members can hear their own audio output if their output level is set to 0dB.
