Presonus NSB 16.8 Networked Stage Box: Scalable AVB Stage Connectivity

The Presonus NSB 16.8 Networked Stage Box Black brings live sound engineers a robust and versatile I/O expansion solution. Purpose-built for StudioLive Series III digital mixers, this model delivers 16 high-headroom XMAX mic preamps and 8 professional-grade XLR outputs directly to the stage, reducing analog cable runs and preserving audio integrity. Fully AVB-compliant, the NSB 16.8 integrates easily into digital audio networks, enabling remote preamp and phantom power control from both consoles and Universal Control software. What stands out is its reputation as a road-ready workhorse for demanding event environments.

Standout Features: Advanced Networking & Gain Compensation

Dual AVB Ethernet ports with locking XLR jacks make daisy-chaining and flexible deployment on large stages straightforward. Each of the 16 remote-controllable XMAX preamps features gain compensation, so input levels stay stable and independent when using several mixers on the same AVB network. With a soft "Mute All" button, combo input jacks, and a robust chassis, this model is engineered for reliability in digital stage applications.

Flexible Input Architecture for Live Sound

Adapting routing is critical for modern stage productions. Extensive, remotely manageable inputs and outputs simplify complex configurations and enable precise control.

• Inputs: 16 locking combo (XLR/TRS) with remote XMAX preamps — a design that accommodates vocals, instruments, and more for a wide range of stage needs.
• Signal paths are optimized for various sources, thanks to a Gain Range of 0 dB to +60 dB.
• Phantom Power: +48 VDC — supports condenser microphones with remote activation.

Networked Output Power and Control

Reliable, high-headroom outputs enable the NSB 16.8 to drive any professional PA or recording system with clarity and authority. Audio routing via AVB supports FOH, monitors, and recording workflows for any venue size.

• Outputs: 8 locking XLR — robust, secure connections ensure stable main and auxiliary sends.
• Long cable runs and powered speakers are easily handled with a Max Output Level of +24 dBu.
• Output Impedance: 100 Ω — compatible with most professional equipment.

Performance Specs for Modern Stages

Audio quality and reliability are paramount in critical live settings. This unit delivers transparent sound, low noise, and diagnostic tools for smooth operation.

• Frequency Response (Inputs): 20 Hz – 20 kHz (±0.5 dBu) — captures the full spectrum of modern stage instruments and vocals.
• Expect clean audio for high-fidelity mixing and recording, thanks to a Signal-to-Noise Ratio of 94 dB (mic/line).
• Dynamic Range (Digital): 115 dB (A-weighted, 48 kHz) — delivers ample headroom and detail in complex mixes.

Who Is It For: Pro Engineers and Growing Venues

Rental companies, production teams, churches, and venues looking to expand input capacity and streamline cabling will find this model ideal. The Presonus NSB 16.8 Networked Stage Box is suited for professionals needing remote control, pristine audio, and AVB network integration in a reliable, road-tough package. Designed for compatibility with StudioLive Series III mixers, the NSB 16.8 supports scalable solutions from clubs to large events. Advanced users appreciate its modular, repair-friendly design and easy integration with third-party AVB gear.
