share on:

Press Release (Edited):  Libertyville, IL MB Quart announced an upgrade series to its current NA marine amplifier line.  The new Nautic Series 3 (NA3) amplifiers use conformal coated PC boards to protect against the elements.

The Nautic Series 3 line includes a 5 channel amplifier to run a full system with 4 full range channels and a 5th channel to power the subwoofer as low as 1 ohm. The 5 channel amplifier has a bass remote for fine tuning. Additionally, a full range, 6 channel amplifier can run several more sets of speakers around the vessel.  A third model is a full range 4 channel amplifier.

Brian Sherman, Vice President of Product & Marketing for Maxxsonics USA said, “These amplifiers represent a huge leap forward for high-power marine amplifiers and are built on an all-new architecture that you’ll soon see in other MB Quart products. A 360° heat sink design ensures best in class thermal stability, while top mounted controls and modular connectors make install and setup a breeze.”

The NA3 amplifiers are IPX certified to handle harsh marine conditions of both salt and fresh water. They offer top-mounted controls and have a 360 degree heat sink design.

“If you could look inside the amplifier, you would see that the amplifier PC board is floating and designed with components in a 360 degree layout. This gives the NA3 amplifiers best-in-class, thermal stability due to the fact that each output device (MOSFET) has ample aluminum heat sink area for cooling,” said Maxxsonics, MB Quart’s parent company.
