Why Choose Analog Summing Over In-the-Box (ITB) Mixing?

1. No Mix Collapse
Preserve clarity and punch — ITB mixes often flatten on export.

2. Superior Instrument Separation
Achieve a deep, wide 3D stereo image with analog summing.

3. Enhance Your Apollo Output
Drive the analog summing inputs from your Apollo for subtle harmonic warmth and pleasing saturation.

4. Add Final Color and Character
Use your Apollo Unison preamps to shape the final tone with true analog flavor.

As an audio engineer, I’m always on the lookout for gear that can improve the sound quality of my recordings. Recently, I had the pleasure of testing out the custom passive summing mixer designed for Apollo x8 – x8p by VintageMaker, and I must say I was blown away by the results.

The mixer features 10 inputs and 4 outputs, allowing me to sum multiple channels of audio from my Apollo interface into a stereo mix. The balanced analog signal path provides a warm and natural sound, with excellent clarity and depth.

One of the things I love about this mixer is its simplicity. It’s a passive design, which means there are no active components to introduce noise or coloration. It simply sums the signals together, allowing me to achieve a more cohesive and musical sound.

The build quality of the mixer is excellent, with a sturdy metal chassis and high-quality connectors that feel solid and reliable. The unit is also compact and portable, making it easy to take with me on location recordings or to use in a home studio setup.

Overall, I would highly recommend the custom passive summing mixer designed for Apollo x8 – x8p by VintageMaker to any audio engineer looking to improve the sound quality of their recordings. It’s a fantastic piece of gear that delivers excellent results and is built to last.
