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.
