ASHLY NX1.52 Multi-Mode Power Amplifier 2 x 1.5KW @ 2/4 Ohms & 70V, 1250W @ 8 Ohms

Product Overview

The Ashly NX1.52 is a two-channel high-output multi-mode power amplifier delivering 1500 watts per channel at 70V, 4 ohm, and 2 ohm loads, and 1250 watts per channel at 100V and 8 ohm loads, without network control or onboard DSP. As a base-level NX series amplifier, the NX1.52 is configured via rear panel DIP switches and designed to work with external DSP processors in commercial AV installations requiring maximum output in a two-channel constant-voltage or low-impedance format. The consistent high-wattage output across 70V and low-impedance loads makes the NX1.52 a practical choice for large house of worship systems, concert halls, convention centers, and commercial installed audio requiring substantial per-zone power without the overhead of integrated DSP or network management.

Product Description

The Ashly NX1.52 commercial power amplifier delivers two channels of 1500W output for the most demanding large-format installed audio zones. Each channel is independently configurable for 70V or 100V constant-voltage or low-impedance operation at 2, 4, or 8 ohms via rear panel DIP switches. With 1500W/ch at 70V and both 2 and 4 ohm loads, the NX1.52 provides high-capacity 70V distribution suitable for large commercial spaces with extensive speaker arrays. At 8 ohm and 100V, output is 1250W/ch, still substantial for most large installed audio zones. The switch-mode power supply operates on 120V or 230V AC input without adjustment, enabling deployment in both domestic and international installations. Class-D switching amplifier technology maximizes efficiency in a rack-mount chassis that occupies minimal rack space relative to its output capacity. Multiple independent internal power supplies improve channel separation and reliability when both channels are driven simultaneously at full output. Continuously variable cooling fans keep operating noise low during standby and low-demand periods, which matters in quiet listening environments. The front panel power switch and level controls can be disabled to prevent unauthorized adjustment in publicly accessible rack locations. Remote DC level control per channel supports integration with external volume control and zone management hardware. The Ashly EMS provides automatic sleep mode drawing less than 1 watt during idle periods. The NX1.52 is manufactured in the United States, TAA compliant, and carries a 5-year limited warranty.

Technical Specifications

Frequently Asked Questions

Does the NX1.52 include network control or DSP?

No. The NX1.52 is a base-level NX series amplifier configured entirely via rear DIP switches. For network control at this output level, consider the NXE series. For DSP at this output level, consider the NXP series.

What is the output power difference between 70V and 8 ohm loads?

The NX1.52 delivers 1500W/ch at 70V, 4 ohm, and 2 ohm loads, and 1250W/ch at 100V and 8 ohm loads. Output is consistent across its highest-demand configurations.

Does the NX1.52 work on international power?

Yes. The switch-mode power supply auto-detects 120V or 230V AC input for international installation compatibility without adjustment.

Can the front panel controls be locked?

Yes. The power switch and level controls can be disabled to prevent unauthorized access in publicly accessible rack installations.

What is the NX1.52 warranty?

The NX1.52 carries a 5-year limited warranty and is manufactured in the United States. It is TAA compliant and certified RoHS, cTUVus, CE, and FCC.
