Product Overview
The Ultimate Solution for Precision Analog Insert Routing and Automated Recalls
In a professional mastering setup, changing the sequence of analog equalizers, compressors, limiters, and harmonic saturators drastically alters the final master tape or print. Traditionally, comparing whether an EQ should sit before or after a compressor required physical patchbays, cable swaps, and brief signal drops that disrupted critical listening focus.
The SPL Hermes removes this friction completely. It acts as an intelligent, automated routing brain that allows you to connect up to eight premium stereo processors via standard DB25 connectors. Engineers can re-arrange the processing order of all eight slots freely, store up to four complete routing matrix presets in internal memory, and swap layouts instantly with zero signal clicks, pops, or latency gaps—preserving the acoustic snapshot in your mind.
Product Description
Unrivaled Headroom with 120V Rail Technology:
Like all legacy units in SPL's mastering tier, Hermes operates on a high-voltage plus/minus 60V DC internal audio rail—effectively double or quadruple the operating power of common pro-audio gear. This immense electrical framework delivers a massive +32.5 dBu of clean headroom, an expanded dynamic range, and a vanishingly low noise floor. Complex mastering signals containing sharp transient spikes, heavy sub-bass energy, and dense high-frequency content pass through the router with absolute transparency, zero compression artifacts, and zero harmonic distortion.
Dual Parallel Mixing Stages with Step Controls:
A standout capability of Hermes is its Dual Parallel Mix (Mix 1 and Mix 2) engine. This feature allows you to choose any two insertion points out of the eight active loops and assign them to independent parallel processing channels. Using high-grade, stepped potentiometers, you can blend the dry uncompressed signal with the wet processed output in precise steps from 0 percent to 100 percent. This lets you apply aggressive, hard-knee compression or saturating grit to individual components while retaining the clean transient punch and open dynamics of the original mix.
Automated Presets and Comparative Auditioning:
The faceplate interface features an intuitive, logic-driven memory matrix that saves up to four distinct routing configurations. This allows for immediate, seamless comparative testing between two radically different processing strategies. Furthermore, the unit features an intelligent Auto-Bypass engine with an adjustable speed interval control. This toggles your analog processing loops on and off automatically at preset times, allowing you to move to the sweet spot of your studio and judge processing adjustments objectively without loudness bias.
Lossless Routing Matrix Layout:
The physical backpanel configuration segregates processing paths over balanced DB25 connection ports wired to TASCAM standards, while the main input and print output paths deploy heavy-duty gold-plated XLR terminals. Every single internal trace uses gold-plated gas-sealed relays to execute path switches. This guarantees that whether a processor is engaged at position 1 or position 8, the signal meets zero inductive loss, zero cross-talk bleed, and zero impedance degradation across a vast 4 Hz to 300 kHz frequency response spectrum.
