DP564 Multichannel Audio Decoder Listening Room Calibration
5-9
For future reference, if you calibrate the subwoofer with an RTA, measure the
calibrated level with an SPL meter and note the meter reading for the proper
calibration. Use this measured value for quick future checks of the system calibration.
When you have set trim levels for all channels, return to the Channel Trim menu,
select Test Noise, select Off, and press Enter.
5.4 One-Touch Output Level Adjustment Dim provides a one-touch level adjustment. It applies a level shift you specify to the
current volume setting.
The range of settings for Dim is +6 to –30 dB, or Mute.
To set the level shift for Dim:
1. On the Monitor Configuration menu, select Dim Gain and press
Enter.
2. Use the ▲▼ buttons to find the setting you want, and press Enter.
At any time, you can apply that level shift by pressing Dim. You can return to the
previous level by pressing Dim a second time. This enables you, for instance, to lower
the listening level to allow a conversation to take place easily, and then return to the
previous listening level at one touch. The Dim button is lit when the level shift is
active.
