ASHLY NX1502 Power Amplifier 2 x 150 Watts @ 2 Ohms

Product Overview

The Ashly NX1502 is a two-channel multi-mode power amplifier delivering 150 watts per channel across all load configurations — 25V, 70V, 100V constant-voltage, and 2, 4, or 8 ohm low-impedance — without network control or onboard DSP. As a base-level NX series amplifier, the NX1502 is configured via rear panel DIP switches and designed for use with external DSP processors in commercial AV installations requiring two independent output zones with 25V constant-voltage support at a cost-effective entry point. The consistent 150W/ch across all load types including 25V makes the NX1502 a practical two-zone amplifier for compact commercial installations, meeting rooms, retail spaces, and smaller educational facilities that use 25V speaker systems and manage signal processing externally.

Product Description

The Ashly NX1502 commercial power amplifier delivers two-channel multi-mode amplification at 150W/ch in a compact rack-mount chassis. Each of the two channels is independently configurable for 25V, 70V, or 100V constant-voltage or 2, 4, or 8 ohm low-impedance operation via rear panel DIP switches, requiring no software for initial setup. The NX1502 is the entry-level two-channel amplifier in the NX series lineup, providing 25V constant-voltage support alongside 70V, 100V, and low-impedance configurations at 150W/ch. This makes it suitable for retail spaces, small meeting rooms, classrooms, and compact two-zone commercial installations where 25V speaker wiring is in use and external DSP handles signal processing. The switch-mode power supply auto-detects 120V or 230V AC input for international installation compatibility. Class-D amplifier technology provides high efficiency in a space-efficient chassis. Multiple independent internal power supplies deliver improved channel separation at simultaneous output. Front panel level controls and power switch can be disabled for secure installation in publicly accessible locations. Remote DC level control per channel supports integration with external zone management hardware. The Ashly EMS provides automatic sleep mode drawing less than 1 watt during idle periods. The NX1502 is manufactured in the United States, TAA compliant, and carries a 5-year limited warranty. For the same 150W/ch with network monitoring added, see the NXE1502. For DSP, see the NXP1502.

Key Features

• 150 W/Ch Across All Loads — Consistent 150W/ch at 25V, 70V, 100V, 8 ohm, 4 ohm, and 2 ohm for straightforward two-zone capacity planning.

Technical Specifications

Frequently Asked Questions

Does the NX1502 support 25V constant-voltage speakers?

Yes. Both channels support 25V, 70V, and 100V constant-voltage operation, covering compact commercial installations with 25V speaker systems.

What is the difference between the NX1502, NXE1502, and NXP1502?

All three are two-channel 150W/ch amplifiers with 25V support. The NX1502 is DIP-switch configured only. The NXE1502 adds Ethernet-based network monitoring and control. The NXP1502 adds full Protea DSP and Ethernet control.

Does the NX1502 work on international power?

Yes. The switch-mode power supply auto-detects 120V or 230V AC input.

Can the front panel controls be locked?

Yes. The power switch and level controls can be disabled for secure installation in publicly accessible rack locations.

What is the NX1502 warranty?

The NX1502 carries a 5-year limited warranty and is manufactured in the United States. It is TAA compliant and certified RoHS, cTUVus, CE, and FCC.
