Warm Audio WA-2A Tube Opto Compressor

- Peak Reduction - The peak reduction control on the WA-2A applies the “amount” of compression from the 2A to the signal. This is on a percentage scale with “100” equalling 100%, which is 40 dB of gain reduction.
- Output Gain - The output gain control adjusts the amount of makeup gain applied to the output signal. This is on a percentage scale with “100” equalling 100%, which is approximately 40 dB of makeup gain. Take care to monitor DAW or recording device input levels as you raise the makeup gain to avoid unwanted clipping.
- Pre Emphasis - This control adjusts the sidechain audio that directs the optical module to compress. Set all the way to the “flat line” image, the optical module responds to peaks across the full bandwidth of the audio source with no frequency filtration. As you move the control towards the “high pass line”, the WA-2A will become more responsive to high frequency transients and “disregard” some lower frequencies in applying compression.
- Stereo Link - The dedicated TRS stereo link input on the back of the WA-2A allows for quick connection between two WA-2As making stereo optical compression easy and intuitive. When linked, the linked 2As will share threshold response, so it’s important to manually match the front-panel controls, especially the output gain.
