Since 1984, German manufacturer SPL offers analog and digital audio signal processors for the professional sound and music production.
Milestones of our R&D history are the patented VITALIZER® sound optimization processor, the invention of the mother of all transient design tools, the TRANSIENT DESIGNER, the launch of the world‘s first discrete 5.1 surround miking system ATMOS® 5.1 already in 1998 and the development of the SPL SUPRA op-amps with an unprecedented operating voltage of 120 Volt.
The SUPRA op-amps are the integral components of our 120 V Mastering Series product line which is setting new benchmarks in audio signal processing to outperform any existing analog or digital audio format.
In 2008 a new team of software developers accomplished the breakthrough in developing digital products without compromising sound quality. Thanks to a new approach in component modeling, the digital products finally met SPL‘s general demands on sound quality.
With the advanced line of ANALOG CODE® plug-ins, SPL makes its unique audio signal processors also available for all important digital platforms and formats and invites audio professionals to rediscover analog in any environment.
