SPL present a versatile routing matrix with the power to harness up to eight stereo processors. With this immensely talented product rerouting, custom preset creation and sample comparison are all available at the touch of a button.

New Mastering Frontiers

Historically mastering routers were custom built by in house engineers to wildly bespoke specifications. Keen to untangle this industry knot, SPL devised a professional mastering router which could mould to applications, optimise mixes, and ensure engineers never again became lost amongst their patch cords.

Ready To Rock

HERMES features everything mastering houses could need in a single prepatched rack. Armed with two parallel mix stages, any of eight individual processors can be engaged, allowing ease of comparison between different mix settings or compression chains with all configurations storable in local memory. This enables extremely fast workflow and cuts out previously laborious repatching operations to find the correct dynamics for a particular track.

Bring Your Gear Back Within Reach

HERMES allows engineers to rediscover the talents of existing signal chain processors thanks to its ease of reordering configurations to achieve new sounds. Rather than investing in new processors, invest in HERMES to get the very most from your current gear and fast!
