Step 3: Connect the Compressor to the Interface
This step varies depending on the routing you want to achieve. You can either connect the compressor in a series or parallel configuration.
Connecting in Series
This is the most common method of connecting a compressor. Here’s how to do it:
- Take the output of your audio source (like a microphone or instrument) and plug it into the input of the compressor using an appropriate cable (e.g., XLR or TRS).
- Connect the output of the compressor to one of the inputs on your audio interface.
- If your audio interface has a ‘Line In’ option, use it for connecting the compressor’s output. This guarantees a higher input level without distortion.
Connecting in Parallel
Parallel compression allows you to blend the compressed signal with the original uncompressed signal, resulting in a more dynamic range while retaining punchiness.
- Input from the audio source connects to the compressor’s input.
- Retrieve the output from the compressor and connect it to the audio interface.
- Use an additional direct connection from your audio source to another input on the audio interface.
- In your DAW, adjust the levels to blend the two signals to achieve the desired sound.
Step 4: Adjust Compressor Settings
Once everything is connected, it’s time to adjust your compressor settings for optimal sound. Important settings include:
- Threshold: The level at which compression begins. Set this based on the input signal.
- Ratio: Determines how much compression is applied. A 2:1 ratio means that for every 2 dB above the threshold, the output will only increase by 1 dB.
- Attack: Controls how quickly the compressor responds to an incoming signal. Faster attacks can enhance presence and punch, while slower attacks preserve transients.
- Release: This setting dictates how soon the compressor stops working after the signal drops below the threshold. Shorter releases can create a pumping effect, while longer releases provide a more natural sound.
- Makeup Gain: Use this setting to boost the output level after compression to compensate for any gain reduction.
Step 5: Test and Fine-Tune Your Settings
Speak, play, or sing into the microphone while monitoring the compressor’s meter. Adjust the threshold, ratio, and makeup gain accordingly to find the sweet spot where the sound is controlled but still retains its natural character.
