2. External Hardware Processor: The external hardware processor receives the audio signal from the send connection. It applies the desired processing to the signal, such as compression, equalization, or effects. The processed audio then flows to the return connection.

3. Return: The return portion of the insert is where the processed audio signal returns to the original signal path. This is where the audio signal is re-integrated back into the audio interface’s signal flow, ready for further processing or routing.

When configuring signal routing with inserts, it’s important to consider the order in which your external hardware processors are connected. Placing different processors in different positions can yield different sonic results.

For example, if you have a compressor connected to one insert and an equalizer connected to another insert, the order in which these processors are placed in the signal chain can affect the sound. Placing the compressor before the equalizer will result in different dynamics and tonal characteristics compared to placing the equalizer before the compressor.

Signal routing with inserts also allows for flexibility in applying processing to specific tracks or the overall mix. You can choose to insert external processors on individual tracks, such as vocals or drums, to shape their sound. Additionally, you can insert processors on the master bus to apply effects or processing to the entire mix.

It’s important to note that inserts provide a “break” in the signal chain, allowing for the integration of external hardware processors. This means that when an insert is engaged, the original signal bypasses the internal processing of the audio interface and is solely processed externally. This can be advantageous when using high-quality external gear or when aiming for a specific sonic character.

Ultimately, understanding signal routing with inserts gives you the ability to tailor your audio processing and shape the desired sound in your recordings or live performances. Experimenting with different routing configurations and the order of processors can lead to unique and creative results.
