Hertz SPL Show S8 DSP – Compact 6 Analog In + Digital In, 8 Outputs, Hi-Res DSP Processor

Meet the Hertz SPL Show S8 DSP, a compact digital interface processor designed to elevate audio setups with precision and reliability. Housed in a corrosion-free metal and composite chassis, it blends rugged construction with high‑fidelity signal handling and a Hi‑Res certification that signals refined performance across digital‑to‑analog stages.

Flexible, high‑resolution processing

At the heart is a 32‑bit DSP engine that handles six analog input channels, one digital coaxial input, and eight outputs, offering generous routing and tuning options for complex systems. Processing runs at 96 kHz / 24‑bit, enabling detailed dynamic range and clean digital paths for demanding content.

• 96 kHz / 24‑bit signal processing
• 32‑bit DSP engine for precise adjustment
• Six analog input channels
• One digital coaxial input
• Eight outputs for flexible configuration
• Bluetooth 5.0 for wireless control
• CONFIGURATOR app compatibility on iOS and Android

Wireless control and digital connectivity

The built‑in Bluetooth 5.0 receiver lets you wirelessly reach the DSP parameters using the CONFIGURATOR app on a tablet or smartphone. This enables on‑the‑fly tuning and remote adjustments when access to the unit is limited or convenient placement matters. The digital coax input is well suited for connecting a Hi‑Res player or other digital source, preserving signal integrity for critical listening sessions.

• Wireless parameter access via CONFIGURATOR app
• Hi‑Res coaxial digital input for high‑quality sources

Durable build and installation flexibility

Constructed to withstand demanding environments, the S8 DSP combines a robust metal frame with composite materials, delivering a compact form factor that fits snugly into audio racks and installation enclosures. The multi‑input/multi‑output design supports a range of configurations, from home theaters to professional installations, without compromising signal paths.

In practice, you can imagine routing analog and digital signals through tailored EQ, dynamics, and crossover settings, then monitoring results through precise imaging and depth. The result is a platform that keeps the focus on what you hear while offering the tools to fine‑tune the experience as needed.

This device is designed for audio professionals and enthusiasts who value flexibility, solid build quality, and the potential for precise tuning, without implying guarantees about outcomes.
