DF4041-2 EXPANDER/GATE
Stereo Expander:
Ratio : Normal, varies with level 1.5/1 to 5/1 - Fixed 2/1 (button)
Threshold : 0/-40dBu variable
Attack : Normal 4 m-sec. FAST (button) 50µs
Recovery : 75ms to 4 sec variable
Depth : 0/40dB variable (extent of expansion below threshold)
Bargraph : Up to 20dB gain reduction
Links : 1 & 2 to external busses or pairs
Stereo Noise Gate:
Gate : Button with LED indication.
All expander controls apply
except Ratio becomes infinite.
Gate Delay : 0/1 sec variable - in addition
to normal 6dB gate hysteresis
Expander & Noise Gate:
DYN-IN : Button with LED indication.
When OFF gives total bypass
condition except that bargraph
operates as a preview at reduced
intensity.
QF4042 PARAMETRIC EQ & FILTERS
Stereo Filters / Equaliser:
2 band parametric filters : HF (low pass) 12dB/octave
: LF (high pass) 18dB/octave
4 band parametric equaliser: +_ 16dB max at selected frequencies
Exclusive lift/cut law allows fine control near centre and low noise in detent.
LF & HF bands can be shelf or bell
(Q 1.0)
LMF & HMF bands can be normal Q
(1.0) or high Q (3.5) bell.
Separate Filters & EQ in buttons.
