Chandler Limited Little Devil pre amp - Manual (Page 3)

GAIN - max gain 66.5
MIC/LINE- There are three different input types on the Devil 500. Mic/line switches
between two of them - the transformer balanced mic or the line inputs. The Little Devil 500
pre is more than just a mic pre. It is processor. Switching to line input processes any
line level source such as tape or DAW tracks, buss submixes or the complete stereo
buss. For unbalanced sources such as bass and keyboards select the DI input.
LOW/HIGH- Selects low or high impedance for BOTH mic and line freq response.
FEEDBACK/BIAS-
How the feedback and bias works. Some users may be familiar with our Germanium
pre amp which incorporated variable negative feedback in a pre amp for possibly the
first time. On the Devil we wanted to take this a step further and allow you to change the
bias of the gain stage AT THE SAME TIME as the feedback.
So what does this mean?
Well you can modify about any parameter of the sound of the pre with the use of the feedback/bias
control. It will change the frequency response in the hi and low areas, harmonic distortion, nature of
clipping, and the overall tonal characteristic of the pre amp. For example with the feedback on full the
sound gets “gushy” as users have described. The unit will soft clip much earlier, harmonics increase
exponentially, hi frequency is slightly increased and the unit takes on a very high voltage “overbiased”
Class A personality.
With the feedback control low you get a very colored but more “tame” sound. Harmonics are very low
(in the range of .007%) and noise is the lowest possible with the unit, in the area of -93db. The sound
could be described as an accurate but interestingly colored Class A sound.
With the Feedback/Gain near the middle of its operation you will get the most headroom and what
could be considered the most typical operation of a mic pre. All parameters tend to come into the
norm for a Class A style mic pre, BUT don't let that keep you from using it set there! The pre always has
a great colored sound we all look for!
