Meridian Audio 565 - Manual (Page 21)

Using the digital surround processor
17
The digital surround processor adjusts the volume in precise
steps of 1dB, where 9dB is equivalent to doubling the loudness.
The current volume setting is displayed in dB on the front panel
display, and can be varied in the range 1 to 99dB. When you first
connect power to the digital surround processor the volume is
set to 65, which is similar to the mid-way position of the rotary
volume control on a conventional preamplifier.
A setting of 87 corresponds to THX reference gain, the level at
which film soundtracks are mixed. For normal to high level
listening you should expect to use volume levels in the range 60
to 90.
To change the volume
● Press the red A or V keys on the remote.
As you adjust the volume setting the display shows the current
volume level.
For example:
Music 70
