The input section

9V DC input

 – Plug a standard 9V pedal PSU (plus 

outside) or insert a 9V battery.

(Main)  INPUT

  –  Plug  a  TS  instrument  jack  cable 

carrying  either  line,  instrument  or  dynamic  mic 

signal.  Be  sure  to  use  a  proper  XLR  to  mono  TS 

adapter  jack.  Stereo  TRS  jacks  will  not  work.  If  a 

mono TS plug is not inserted into the INPUT then 

the unit won’t turn on.

THRU

 – An unbuffered copy of the input for direct 

recording, amp or daisy chaining multiple ACS.

IP GAIN

 – Can amplify the input from 0 to 40dB. The impedance looking 

into the input is 100kOhm. Set this knob while the source audio is playing. 

Turn up until the “over” LED lights up on the highest peaks.

2 POLE / 4 POLE

 

sw.

 - The auto-filter which helps frequency detection can 

be  configured  as  2-pole  in  the  down  position  (for  faster  transient 

response) or 4-pole in the up position (for more filtering of harmonics).

Input LED meter

 – A 4 character LED meter to show the input’s level. The 

bottom LED lights up when the ACO’s gate is open.

GATE

 – Controls the gate threshold level. Turn it low if the source doesn’t 

have much noise and you wish to enjoy more dynamic range or sustain. 

Turn it higher to reject any noisy bursts present in a less clean source.

S. Chain Audio in –

 Auxiliary audio input for the 2

nd

 ENV follower.

S. Chain to ENV sw. –

 Bottom = S. Chain off, middle = S. Chain on, top = S. 

Chain on with +15 dB gain for lower level sources.
