Ashly CA-504 power amplifier

The Ashly CA-504 is a four-channel Class D power amplifier and part of the CA series. With this series, Ashly takes Class D performance to a whole new level, with their proprietary ultra-efficient D-MAX technology. The engineers applied advanced design practices and state-of-the-art components to achieve something truly unique. Ashly CA-504 and the other power amplifiers from this series therefore represent new pinnacles in the world of power amplifiers.

Powerful. Clean. Reliable.

CA-504 is lightweight and power efficient. In combination with Ashly’s newly engineered ultra-high-speed switching power supply and intelligent power management, the end result is nothing short of stunning. All transient impact and spatial details of the sound are preserved. With a power amplifier like this, it will never be necessary to drive loudspeakers to the brink of destruction. Your loudspeakers have never been so happy! Some advantages of this amplifier are:

  • The amplifier supplies 500 Watts per channel
  • Selectable gain per channel with, lock-out
  • Adjustable input
  • Stability to 2 Ohms
  • Solid metal front panel
  • Installer friendly Euroblock and XLR combo connectors
  • Switchable HPF and Clip Limiter per channel
  • CV remote ports per channel

Coolest amplifier ever

The CA-504 is the most efficient amplifier to date, by far. The pay-off is less heat, lower distortion, more stable operation and greater reliability. The amplifier even runs so cool that bulky heat sinks, used in most other amplifiers, are no longer required. Instead, the CA-504 is able to optimise active air cooling using Ashly’s newly developed bi-lateral SailFlow cooling, which moves the air along a selective path, to where cooling is most needed.

Excellent in all kinds of applications

Ashly CA-504 is specifically designed to excel in performances installations. However, due to 70 & 100V direct-drive capability and more integration-friendly features than are typically found on many amplifiers, this power amplifier is also right at home in commercial installations. Thanks to the WR1.1 wall remote, this amplifier is very easy to operate in any situation. The black with grey amplifier is therefore perfect for use in, among others, auditoriums, places of worship and theatres.

For every application the ideal power amplifier

The Ashly CA series consists of six 2 or 4 channel models with 500, 1000 or 1500 Watts per channel. So there is a CA amplifier for every project and any conceivable application.
