Product Overview

The N 248 (008537) is engineered for versatility and audio purity. While it functions as a high-quality universal 48 V phantom power supply for any condenser microphone, its standout feature is the integrated rotary switches for pattern control. By subtly varying the phantom voltage (a patented Neumann technology), it allows engineers to switch between five directional patterns remotely, saving time and effort during complex recording sessions.

Product Description

Dual-Channel Versatility:

The N 248 is equipped with two independent channels, each featuring high-quality XLR 3 connectors. It can simultaneously power two separate mono microphones or a single stereo microphone (like the SM 69 series). Because the channels are independent, you can even engage in mixed operation: one channel can remote-control a TLM 170 R while the other provides standard 48 V power to a completely different microphone model without interference.

Patented Remote Pattern Control:

When used with the TLM 170 R or TLM 127, the N 248 acts as a remote commander. By using the front-panel rotary switches, you can toggle through the five polar patterns (Omni, Wide-Cardioid, Cardioid, Hypercardioid, and Figure-8) without touching the microphone. This is achieved by varying the nominal 48 V voltage within a ±3 V range—a safe, patented method that works over standard microphone cables up to 300 meters long.

Audiophile-Grade Signal Path:

Neumann has ensured that the N 248 does not color or degrade your audio. The audio signal outputs are entirely DC-free, protecting your preamp inputs from unwanted offsets. The internal switching regulator is highly filtered to eliminate electronic noise, ensuring that your high-end microphones maintain their full dynamic range and industry-leading signal-to-noise ratios.

Compact and Desktop-Ready:

The N 248 features a rugged, space-saving design that fits comfortably on any studio desk or equipment rack shelf. The unit is powered by an included external plug-in power supply, keeping the high-voltage AC components away from your sensitive audio lines. Its sleek Black finish and intuitive layout make it a professional addition to any modern control room.
