Restoration / Analog systems / Digital upgrades

Many music and audio enthusiasts favor vintage and high-end equipment for its distinctive sonic character, whether for professional or home use. That’s why we offer specialized services to restore these systems to their original condition and specifications. When desired, we can even enhance them through carefully planned upgrades or replacements using high-quality components, blending modern audio technology with the authentic tonal character and ‘musicality’ of the original design.

Many first- and second-generation high-end digital audio systems benefit greatly from upgrades that include refined A/D and D/A conversion stages, high-precision FIR digital interpolation filters, superior current-to-voltage (I/V) conversion topologies, and meticulously optimized low-pass filtering on both input and output stages, all contributing to greater resolution, improved transparency, and a more natural, balanced presentation.

Fully analog systems can also be restored to their original factory specifications using high-quality components. This applies both to semiconductor-based systems (commonly referred to as solid-state in the early 1970s) and to those using vacuum tube technology.

Studio installation / System configuration / Measurements

All adjustments and measurements are carried out using high-end professional equipment, including systems from Rohde & Schwarz and Audio Precision. For more information about our Broadcast Audio services, please contact our engineer, Harry v.d. Schans.

Acoustic measurements / Structure-borne noise / Compliance

In accordance with local noise pollution regulations, it is essential to ensure that any installed sound system complies with relevant environmental and building standards. This obligation typically applies to venues such as restaurants, nightclubs, theatres, concert halls, and other spaces where amplified sound is part of regular operations. Non-compliance can result in fines, community complaints or even suspension of operating licences.

To ensure compliance, venue owners work with our acoustic consultant to measure both airborne and structure-borne noise, with a focus on low-frequency transmission that may affect neighbouring properties. Sound-level meters and real-time analysers are used to assess airborne sound pressure levels across frequency bands, while accelerometers are deployed to monitor structure-borne vibrations travelling through floors, walls and foundations (in both directions) to evaluate potential emission and ingress of unwanted noise.

Upgrading or replacing an existing audio or PA system can significantly alter a venue’s acoustic signature, potentially increasing sound transmission beyond acceptable limits. This risk is heightened when higher-powered equipment, subwoofers or differently oriented speakers are introduced. To prevent costly retrofits or legal issues, it is advisable to perform predictive modelling and in-situ measurements, both before and after any modifications.

Mitigation strategies may include installing soundproofing materials (e.g., bass traps and acoustic panels), isolating speaker mounts to reduce structural vibrations and implementing digital signal processing (DSP) to control output in sensitive frequency ranges. Noise limiters and time-of-day restrictions may also be enforced to balance venue operations with community well-being.

By integrating acoustic compliance into the design and operations of a venue, stakeholders not only adhere to regulations but also foster improved community relations and sustainable business practices.
