Technical Aspects

120 Volt Technology

SPL‘s goal was to push analog signal processing to the limits. That‘s why we combined

the best possible components with a high-grade optimized circuit design.

We have been using the in-house developed 120 Volt technology - the highest-ever oper-

ating voltage used for audio applications - in all our products from the Mastering series

for years. Some of the most highly respected Mastering studios today revolve around

SPL consoles and signal processors from our Mastering series (Bob Ludwigs Gateway

Mastering & DVD in the USA, Simon Heyworth‘s Super Audio Mastering in the UK, Galaxy

Studios in Belgium, and the legendary Wisseloord in the Netherlands, for instance).

The 120 Volt technology is based on op-amps developed internally by SPL‘s co-founder

and Chief Developer Wolfgang Neumann. The Hermes Mastering Router features the

most advanced generation of these op-amps. They boast with even better tech specs

thanks to the thermal behavior optimization they underwent under the hands of Bastian

Neu.

Ultimately, the supply voltage is key for the overall dynamic response of a processor.

Voltage is to an electrical circuit what cylinder capacity is to an internal combustion

engine:

You can‘t replace cylinder capacity with anything else, except more cylinder capacity.
