10×4 Input Analog Summing Mixer with insert designed for UAD – Focusrite ISA828

Dual stereo discrete signal path, fully balanced from input to output!
8 + 2 (AUX) Input Passive Summing mixer (10×4) TRS/DSUB designed for Garage Band, Steinberg Cubase Pro 12 UAD Apollo x8 and D. W. Fearn VT Microphone Preamp,Grace Design m501 500 Series Microphone Preamp
Summing Mixer with insert designed for UAD (Unison Preamps) – Switch Insert Bypass SND/RET for Focusrite ISA8288

DIR/SUM Input: Link AUX In (line) signal or another (second slave) Passive or Active summing unit.
Switch DIR = 0dB reduction in AUX in (no gain loss).
Switch SUM = Summing mixer input (dB reduction equal to summing reduction).

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).
