release – as Fairchild 670 etc. Attack and release
times are in 3 categories each – Fast (F), Medium (M)
and Slow (S). Each switch position is a composite of
Attack / Release.
1
= F/M, 2 = F/S,3 = M/ F, 4 = M/M, 5 = M/S, 6 = S/M.
3.6 Side Chain Bass Cut
This switch reduces the compression on signals below
100Hz - see op hints.
3.7 Presence
This control mimics the highly acclaimed mid-lift
control on the Earlybird 2.. It’s simply a very broad –
band lift peaking at around 3 kHz.
3.8 Air
Boosts the very high end, peaking at:
6.
10 kHz, 5. 13 kHz, 4. 18 kHz – then 3., 2. & 1. are
damped versions of 6., 5. & 4., making the response
broader and more of a ‘shelf’.
3.9 Active EQ
Both "Presence" and "Air" can be switched IN/OUT
together using this switch.
3.10 Output Trim
A reverse linear attenuator, reducing output level by
up to 15dB to suit low level inputs.
