ASHLY CA1.04 High Efficiency Power Amplifier 4 x 1000W at 2/4 Ohms or 70V, 500W at 8 Ohms

Product Overview

The Ashly CA1.04 is a four-channel Class D power amplifier delivering 1,000W per channel at 2 or 4 ohms and 70V/100V constant-voltage capability, built on Ashly's proprietary D-MAX technology for high efficiency and reliable commercial installation performance. With 4,000W total output in a 2RU rack-mount chassis, it occupies the mid-tier of the CA series commercial power amplifier line between the CA 504 and CA 1.54. The CA1.04 is designed for demanding commercial AV applications including large-venue distributed audio, house of worship sound reinforcement, and high-power commercial installation work.

Product Description

The Ashly CA1.04 applies D-MAX Class D amplifier technology to deliver 1,000W per channel at 2 and 4 ohm loads, and 500W per channel at 8 ohms, across four independent channels. The D-MAX design uses an ultra-high-speed switching power supply and intelligent power management to preserve transient detail and spatial characteristics in the audio signal while maintaining efficient operation that avoids excessive current draw. Stable 2 ohm operation means multiple speakers can be wired in parallel per channel where zone coverage demands it. All four channels also deliver 70V and 100V constant-voltage output for transformer-tapped distributed speaker systems, giving integrators the option to deploy the CA1.04 in pure distributed audio environments, pure low-Z environments, or a mix of both. SailFlow directed active air cooling moves air along a selective path to the areas generating the most heat, keeping operating temperatures in check during sustained high-output commercial use. Each channel includes a switchable 80Hz HPF, limiter, and per-channel gain control accessible from the solid metal front panel. A front-panel lockout switch prevents unauthorized adjustment. Balanced Euroblock and XLR combo inputs provide flexible signal connection. Remote VC ports per channel and a remote standby port with switchable polarity support integration with wall-panel controls and building automation systems. The lightweight 2RU chassis fits standard installation racks, and all Euroblock output connections simplify speaker wiring during installation. With a 5-year Ashly warranty, the CA1.04 is built for sustained commercial installation service.

Technical Specifications

Frequently Asked Questions

What is the rated output power of the CA1.04?

The CA1.04 delivers 1,000W per channel at 2 or 4 ohms, and 500W per channel at 8 ohms, for a total of 4,000W system output across four channels at 2/4 ohm loads.

Can the CA1.04 drive 70V distributed speaker systems?

Yes. All four channels support 70V and 100V constant-voltage operation, making the CA1.04 suitable for transformer-tapped distributed audio speaker installations.

Is the CA1.04 stable into 2 ohm loads?

Yes. The CA1.04 is rated for stable 2 ohm operation, supporting multiple-speaker parallel wiring per channel in installations requiring high zone coverage.

How does the CA1.04 differ from the CA 1.54?

Both amplifiers share the same CA series D-MAX Class D design and 4-channel configuration. The CA1.04 delivers 1,000W per channel (4,000W total) while the CA 1.54 delivers 1,500W per channel (6,000W total). The CA1.04 is the appropriate choice when zone power requirements are moderate.

Does the CA1.04 include DSP processing?

The CA1.04 includes switchable 80Hz HPF and limiter per channel for basic speaker protection, but does not include full onboard DSP. For complete DSP processing, an upstream processor such as the Ashly AQZ32 is recommended.
