Product Description
The Palmer NAAB (Item No.: PNAAB) is the ultimate "media specialist" in the RIVER Series. Specifically designed for the modern AV integrator and live sound engineer, the NAAB is the perfect bridge between consumer media devices—like laptops, smartphones, and tablets—and professional mixing consoles.
Whether you are managing a corporate presentation in a boardroom or a background music feed in a high-end lounge, the NAAB ensures your audio is clean, balanced, and free from the hum and buzz typically associated with unbalanced consumer connections.
Versatile Connectivity for Any Device
The NAAB is uniquely equipped to handle the wide variety of outputs found on modern media hardware:
Inputs: 2 x 6.3mm (1/4") Jacks, 2 x RCA (Phono), and 1 x 3.5mm (1/8") Stereo Mini-Jack.
Outputs: 2 x Balanced XLR (Left and Right).
Flexible Routing: Features a Mono/Stereo Switch, allowing you to sum a stereo signal into a single mono output—ideal for saving channels on a small mixer or feeding a mono-distributed speaker system.
Key Technical Features
High-Fidelity Isolation Transformers: Two custom-engineered Palmer transformers provide complete electrical isolation, eliminating ground loops and 50/60Hz interference.
Passive Operation: Requires no power, batteries, or phantom power. It is a "plug-and-play" solution that is always ready for use.
Ground Lift Switch: Instantly breaks ground loops to solve noise issues in complex AV setups.
Audio-Grade Shielding: The internal components are protected against RF (Radio Frequency) and EM (Electromagnetic) interference, ensuring a pristine signal path.
Built for Professional Reliability
Modern RIVER Design: Features the signature ultra-rugged aluminum housing with a solid steel base, built to withstand heavy use in a toolbox or an equipment rack.
Recessed Connectors: All jacks and switches are protected within the frame to prevent accidental damage during transport.
