4.5 Metering

After you have followed the steps in Chapter 1, IQwic is running, and the Input/Output meters window (Figure 4.5) is at the left of the screen. Its features are described below.

1. Output Level Meters

Audio level meters are provided for each output channel: Left, Right, Center, Subwoofer, Surround Left, Surround Right, Back Left, and Back Right. The meters sense the audio signal immediately after the audio output processing block. Meter range is from –60 to +20 dBu with 0.5 dB resolution.

Another meter labeled “Monitor” shows the output level at the Monitor Output connector.

2. Input Level Meters

Audio level peak program meters are provided for each of the input channels: Left, Right, Center, etc. The meters sense the digital or analog audio signal, and respond with 1.7 millisecond attack and 350 millisecond release. Calibra- tion is in dBu when the input is in “line” mode and set at 0 dB. Meter range is from –60 to +20 dBu with 0.5 dB resolution.

3. Preset Information

Last Preset indicates the Preset that is currently displayed. Below that is the label associated with that Preset. The Preset can be changed by IQwic, the front panel of the unit, by the event scheduler (described later), or by a pro- grammed control-port input.

4. Status Window

This window shows the current status of the unit and has three modes:

•Active (green): Indicates that the settings of the unit agree with the displayed Preset.

•Modified (yellow): Indicates that the settings of the unit are different from the displayed Preset.

•Offline (red): Indicates that IQwic is not currently communicating with the unit.
