For each of the three channels there is a volume control that controls how hard the limiter is driven.
When the knob is at 9 o’clock what passes through is almost unaffected but limiting peaks to +/-5V. At 12 o’clock you will have 2,5 times compression still fairly transparent compression. Turning the the knob to full will give 5 times amplification drive in to the limiter, giving a rounded distorted sound.
The three channels are completely independent.
AC/DC coupling for Lim1 and Lim2 is done with the switch on the panel.
AC/DC coupling for Lim3 is done by a jumper on the back of the module.
When the jumper is mounted Lim3 is DC coupled.
The module is delivered with the jumper mounted.
If you want higher compression than just one limiter you can chain several limiters by connecting OUT from one limiter to IN on the next.
Module size: 6 hp wide, 25 mm deep with power connector.
Input impedance: 20 kohm
Output impedance: 1 kohm
Power requirements: +/- 12V. Max power consumption +/- 20 mA
Connect the power cable with the red stripe (-12V) down.
The unit is protected for reverse power.
