4×2 Studio Precision Mastering Summing Mixer XLR – Input Channel Gain Control

Precision gain controlled mastering mixer designed for final mastering purposes, where two master stereos (main stereo + effect) or two stereos need to be summed into one final master stereo before recording. “When mixing reverb into a stereo mix, the levels must also be done carefully so as not to create any smearing.”

Introducing our custom-built unit, tailored precisely for applications like yours. Are you seeking to infuse your master mix with a touch of room reverb, delicately balancing between the divergent opinions of mastering engineers? Look no further.

While some may recoil at the mere suggestion, others will commend your discerning approach. Through meticulous experimentation, we’ve discovered that incorporating a subtle hint of room reverb can yield remarkable results:

1. Undo (diffuse) some of the unwanted artifacts introduced from saturation and compression, especially at high listening levels
2. De-ess sibilant cymbals and vocals
3. Make all the instruments sound like they are playing in the same performance space
4. Enhance the listener’s sense of depth and width of the mix
5. Add air to the mix
As long as a mastering reverb is EQed properly so as not to muddy the mix, this technique can breathe life back into an otherwise 2-dimensional sounding compressed mix. When mixing reverb into a stereo mix, the levels must also be done carefully so as not to create any smearing.

Embrace the transformative potential of our custom unit, revitalizing your compressed mix from two-dimensional confinement to dynamic vibrancy. It’s time to rediscover the essence of your sound, one subtle reverberation at a time.
