ASHLY CA 1.52 Power Amplifier 2 x 1500W @ 4 Ohms, 750W @ 8 Ohms, 1500W 70V

Product Overview

The Ashly CA 1.52 is a two-channel Class D power amplifier delivering 1,500W per channel at 2 or 4 ohms and 70V/100V constant-voltage capability, providing the highest per-channel power available in the two-channel CA series configuration. Built on Ashly's D-MAX technology with Dynamic Power Factor Correction and SailFlow directed cooling, it delivers 3,000W total output in a lightweight 2RU chassis. The CA 1.52 is designed for commercial AV installations requiring high stereo or dual-zone power, including large performance venues, houses of worship, and high-demand distributed audio systems.

Product Description

The Ashly CA 1.52 puts 1,500W per channel at 2 and 4 ohm loads across two independent channels, and 750W per channel at 8 ohms, delivering 3,000W total system output from a single 2RU rack-mount unit. In bridge-mono configuration, the CA 1.52 produces 3,000W at 100V and 2 x 1,500W at 70V for large-venue constant-voltage distributed audio applications. Stable 2 ohm operation allows multiple low-impedance speakers to be connected in parallel per channel for demanding sound reinforcement applications, including subwoofers and high-output line arrays. D-MAX Class D technology uses Ashly's Dynamic Power Factor Correction with Silicon Carbide semiconductor switching, delivering extremely high efficiency that allows multiple CA 1.52 units to operate simultaneously on a single 20-amp service circuit. SailFlow directed active cooling directs airflow specifically to the areas of the chassis generating the most heat, maintaining reliable low-temperature operation under sustained high-output commercial use. Per-channel controls include a switchable 80Hz HPF, clip limiter, and adjustable gain accessible from the solid metal front panel, with a lockout switch to prevent unauthorized changes. Balanced Euroblock and XLR combo inputs provide flexible wiring for professional installation environments. Remote VC ports per channel support wall-panel volume control, and a remote standby port with switchable polarity integrates with building control or AV automation systems. Dual-voltage capability (120V / 230V AC) supports international commercial installations. Made in the USA, the CA 1.52 is built for long-term sustained commercial service.

Technical Specifications

Frequently Asked Questions

What is the rated output of the CA 1.52 per channel?

The CA 1.52 delivers 1,500W per channel at 2 or 4 ohms, and 750W per channel at 8 ohms. In bridge-mono mode, it delivers 3,000W at 100V or 1,500W per channel pair at 70V.

Can the CA 1.52 drive 70V distributed speaker systems?

Yes. Each channel supports 1,500W at 70V, and the two channels can be combined in bridge-mono for 3,000W at 100V, making the CA 1.52 compatible with large-venue constant-voltage distributed speaker systems.

How does D-MAX technology achieve high efficiency?

D-MAX uses Dynamic Power Factor Correction with Silicon Carbide semiconductors that switch on and off faster than conventional silicon, eliminating switching loss and residual tail current. This results in efficiency high enough for two CA 1.54 units (equivalent 4-channel setup) to operate on a single 20-amp circuit.

Is the CA 1.52 made in the USA?

Yes. The CA 1.52 is manufactured at Ashly's facility in Webster, New York.

Does the CA 1.52 include DSP processing?

The CA 1.52 includes switchable 80Hz HPF and limiter per channel for basic speaker protection but does not include full onboard DSP. For complete system processing, an upstream DSP processor such as the Ashly AQZ32 is recommended.
