Figure 6: Compression - limiting signal level graphs

If a compression effect is required together with limiting of high level transients, two

channels of the DN540 may be cascaded. The output of Channel 1 (compression) is fed

to the input of Channel 2 (limiting), which gives powerful two stage control over gain.

Figure 7: Limiting and compression graph

Below the compression threshold, the signal is unaltered. In the example shown in

Figure 7 “Limiting and compression graph”, the first threshold is compressed at a mild

2:1 ratio. Whereas, at the second threshold it is firmly limited at a ratio of 20:1.
