Power your speakers with the ultra-efficient Ashly CA-502, a 2-channel power amplifier that delivers up to 500W of power per channel (3000W bridged). The unit incorporates Ashly's proprietary ultra-efficient D-MAX amplifier technology for the cleanest and most reliable performance with lower power draw. Additionally, the CA-502 can power a variety of speaker types including Low Z (2, 4 & 8 Ohms) to Hi Z (70 or 100V).
The CA-502 is 2 RU and can be mounted into a standard 19" rack enclosure. The rear panel features combo XLR-1/4" inputs and removable Euroblock input and output connections as well as remote VC ports and switchable 80 Hz HPF and Clip Limiter on each channel. The front panel provides a volume control knob for each channel and comprehensive LED indicators for levels and amplifier status.

- When current and voltage are exactly in phase, current demand is reduced and efficiency increased. Dynamic Power Factor Correction tracks current continuously to maintain accurate monitoring & control.
- Silicon Carbide semiconductors boost both speed and efficiency and are significantly faster than the old-school pure silicon of the past.
- Traditional silicon semiconductors don’t shut off instantly. They have a lag time called “switching loss”, leading to a residual tail current (red portions in the drawing at left). From an audio-quality standpoint, this makes for a sloppier, less precise sound; from an efficiency standpoint it sucks up unnecessary power.
- Instead, Ashly is pioneering the use of Silicon Carbide (SiC) semiconductors. They have unique electrical characteristics that render them able to switch on and off far faster than conventional silicon. The result is an amplifier design that’s faster (thus better audio fidelity) and more efficient.
- Power amplifiers need cooling. In most amps, heat-reducing airflow takes a convoluted path in and around internal components. Front to back, back-to-front-side-to-side…those nice, perforated grilles look simple until you look inside the amp and see the helter-skelter airflow.
- Ashly didn’t want cooling air to just wander around inside the CA chassis, so they came up with their unique SailFlow architecture, which directs internal airflow strictly over the areas that generate the most heat, rather than arbitrarily over the whole amp. This keeps the already highly efficient CA Series even cooler and assures reliable, stable operation, even under heavy loads.
