Meter Inserts

Keeping track of signal levels is important in any audio system, be it analog or digital.

You want to keep the signal levels running as close to maximum in order to achieve

high resolution and low noise. On the other hand, you don’t want the signal level so

high as to cause clipping. To help you maintain optimum signal levels, we have

included Peak Level Meters, which can be dropped into any insert location.

The insert meters are of the “peak hold” type. The topmost bar in the meter holds its

highest level for a second to let you see transients that would otherwise be too quick for

the eye.

The peak meters are also color-coded to indicate the signal strength. The chart below

outlines the meanings of the colors. Avoid lighting the topmost red bar, as this

indicates distortion of the signal. Click on the clip indicator to turn it off.

One of the most obvious uses of the insert meters is to set input levels. On the analog

inputs, the analog-to-digital converter (ADC) is one of the most critical points in the

signal path. You want the input signal level to drive the 24-bit ADCs into their

optimum range without clipping. A reading of 0dB on an input meter indicates signal

clipping.
