Highlight Features
Acitve Full Range Speaker K-15AF
The K-15AF is a high-output full-range loudspeaker developed for sound systems that require strong low-frequency reproduction, clear vocal projection, and consistent coverage across large listening areas. Its 15-inch woofer, high acoustic sensitivity, and maximum peak SPL of 131 dB make it a suitable choice for live stages, event venues, auditoriums, clubs, and permanent sound installations.
Product Description
- Advanced digital signal processing: A professional 2-input / 2-output DSP platform operates at 48 kHz / 24-bit resolution using Cirrus Logic audio conversion technology.
- Responsive real-time processing: The hardware floating-point DSP architecture minimizes signal latency while maintaining stable and accurate audio processing.
- Professional loudspeaker management: Dedicated configuration software provides detailed control for system tuning, signal optimization, and loudspeaker performance adjustment.
- Low-noise analog signal path: Fully differential analog audio channels improve common-mode noise rejection and help maintain signal integrity in professional environments.
- Expandable remote control: The integrated RS-485 cascade interface supports centralized configuration and monitoring through the manufacturer’s dedicated USB Bridge.
- Optimized thermal management: A high-efficiency heat sink works together with an intelligent variable-speed fan to regulate operating temperature during extended use.
- Efficient Class D power stage: The digital amplification system achieves conversion efficiency of up to 90%, reducing energy loss while maintaining high output capability.
- Visible operating feedback: Front-panel Signal, Limiter, and Protection indicators allow users to monitor system status and identify abnormal operating conditions quickly.
