How the VS-2400CD Meters Show Signals
Levels are shown on the VS-2400CD's display in
a row of vertically oriented meters. Each meter's
signal is shown as a thick black bar that grows
taller as its signal gets louder. The 48, 12, 4 and 0
markings to the left of the meters show you how
loud the signal is in dBs— -48 dB, -12 dB, -4 dB
and 0 dB—as the black bar varies in height.
How Loud Is Too Loud?
In general, you want each signal to be as loud as possible without exceeding 0 dB. 0 dB
is the loudest a digital signal can get without causing clipping—see Page 58.
Each signal should be in the -12 dB to 0 dB range when you're setting:
•
•
•
When you're mixing, the playback level of individual tracks is determined by how they
sound in the mix, not by metered levels. Fortunately, if you've set each track's recording
level properly, it'll be impossible to set its playback level so that it exceeds 0 dB.
To help you keep track of how loud your signals get, a
peak line representing each signal's loudest level
remains for a few moments in its meter after the signal's
level goes back down. This lets you look from meter to
meter without worrying that you've missed a too-loud
signal peak.
You can set the peak lines so they "stick" at their loudest levels until you release them,
to make sure you don't miss anything important—see "PEAK HOLD Sw" on Page 360.
Pre- and Post-Fader Level Metering
You can meter the level of most any signal:
•
•
You can't meter input signals pre- or post-fader because they haven't yet traveled
through an input channel. You can meter an input channel's signal this way, however.
The meters display's pre/post indicator shows you whether you're viewing pre-fader or
post-fader signals, as shown in the illustration on Page 116. The meter switches
(Page 120) include a switch that lets you select a pre- or post-fader view.
In general, you'll want to view signal levels post-fader. However, it can be helpful to
view pre-fader levels when you're experiencing a problem and need to track down the
precise spot in the signal's signal flow at which the problem is occurring.
