Re: DL4 distortion problem

["Nic Roozeboom" <nicroozeboom@hotmail.com>]

Hi Cam,

My first guess is that the first DL-4 has a setting that is peaking or 
otherwise has a gain noticeably higher than unity. Peaking is when filters 
(such as the sweep effect on the DL-4) emphasize (amplify) a certain 
frequency range. Other ways of achieving above-unity gain is by layering 
several overdubs (although this is compensated in part by the DL-4's own 
internal feedback level control).

In other words, the DL-4 is capable of output signals that exceed its own 
input dynamic range. (This is a property - in fact a virtue - of many 
effects/processor devices, not a fault of this particular design).

A solution might be to route the output of the first DL-4 through 
compression/limiting if available. A second, less desirable approach is to 
reduce the input signal level to the first unit (which has the drawback of 
reducing signal-to-noise ratio by the same amount).
