Replacement Adapter for Yamaha NX-B55

This ABLEGRID AC adapter is built as a non-OEM replacement for the Yamaha NX-B55 Premium Computer Wireless Speakers. It supplies the DC power the speakers require and includes over-voltage and over-heat protection. The unit is CE, FCC and RoHS certified. It is intended for users who have lost or damaged the original mains lead.

AC 100-240V Input with Barrel Tip

The adapter accepts a worldwide AC input range of 100-240V at 50-60Hz and delivers DC output through a barrel-style connector tip. Compatibility is rated at 820% with the original specification. Buyers must verify that the DC output voltage and the barrel tip dimensions match the speaker's requirements before ordering.

Direct Plug-In Installation

Installation is a direct plug-in: connect the mains lead to a wall socket and the barrel tip to the speaker's DC input jack. No tools or configuration are needed. The most common issue is ordering a unit with an incorrect tip size or output voltage, which prevents the speakers from powering on. Ensure ventilation during extended use and avoid placing the adapter on soft surfaces.

Questions about this item

What does the 100-240V input mean when I plug this into a wall socket?

It accepts mains voltage from 100V to 240V at 50Hz or 60Hz, so it works worldwide without a separate voltage switch.

How does the barrel-tip connector limit what I can power?

The DC output uses a barrel tip sized for the Yamaha NX-B55; only devices with the matching jack and correct polarity will connect.

What physical space does the adapter need on a desk or power strip?

The unit is a compact switching brick with an integrated mains lead; it fits a standard socket or strip without blocking adjacent outlets.
