Chandler Limited Zener Limiter - Manual (Page 3)

Controls and Features continued
At unity gain input with the INPUT switch on full you will get about 2% THD. If this is increased
to +4-5db, distortion will increase to around 5%, which is many, many times that of tape
and without clipping.
One excellent use of this is to patch the two Zener channels in series and use the first to Limit
and the second for THD. You can then use the OUTPUT control of the first channel to drive the
second into higher THD percentages while lower the output of the second to control overall
level. Very retro!
OUTPUT GAIN - Another 21-position gold contact switch set for +/-10db of gain control in 1db
steps. Use this for Gain make up when hard limiting or to drive the second channel into a higher
THD range when in THD mode as described above.
COMP/LIMIT - A very important control for tailoring the overall tone of the unit. COMP 1 is a
2:1 ratio with slower time constants that was originally designed by EMI engineers to emulate
the Altec 436/RS 124 EMI modified Altec compressors. Limit is much faster and designed to
emulate the response curves of the much loved Fairchild 660. COMP 2 is a new setting designed
to put you halfway between the two original settings and essentially gives you the compression
curve of COMP 1 with faster release times similar to LIMIT.
