2U Rack 64-Input Ch Summing Mixer – 32 x 64 Mono Swich

2U Rack 64-Input Ch Summing Mixer – 32 x 64 Mono Swich for Logic Pro Apogee DA16X Lynx Aurora Antelope orion with Black Lion Audio Auteur, Universal Audio 6176 – 64 ch input DSUB/DB25 Tascam Balanced, XLR out passive summing mixer with 32 x stereo to 64 mono and variable -15/-25dB gain switch

AUX IN = Line Input / Summing mixer

DIR+BYPASS: Choose the desired input then route to the Master Out + Bypass = Mute all other summing inputs (input can be freely selected).

STM – Stereo to Mono Switch: Gives a stable Real Analog Mono Base for key elements like Kick, Bass, Main Vox, and Snare. Save digital channels and enhance separation with a simple switch, achieving a centered mono signal for hard-panned L/R inputs. Easily toggle for stereo instruments or maintain a fully stereo mix with panning options from your DAW.

Master Insert Send Return Switches: Enables sending the master stereo L/R signal to external processors like EQ, compressor, or limiter, or a Preamp like Focusrite ISA and then returning it to the master output for printing or recording. The ‘Master SND/RET’ is placed before the master out, with 100% of the signal routed to the send.

The system requires two stereo switches for signal isolation and control: The first switch enables sending to external processors (routes the master to SND). The second switch enables the return from external processors (routes the return to the master out).

Variable Headroom Gain Switch: It provides a wide gain-volume range for different applications, offers gain stages between various microphone preamps or DAW interface inputs, and accommodates various source inputs, such as synthesizers or DAWs. Placed after passive SUM BUS (passive mixer) determines main out (total) gain reduction – for different (pre amps) applications – gain stage – volume range. You have a great opportunity to experiment with different gain reductions and determine what sounds better for your mix: 1. Whether it’s with fewer input signals and more amplification. 2. Or the other way around, with more signals and less amplification. Benefits: You can overdrive the summing inputs with different gains to achieve more saturation and warm harmonics.
