Onboard level and temperature monitoring allow remote system management via Ethernet-connected PC software.
Frequently asked questions
What is IPAL technology and how does it benefit the KS8?
IPAL is an amplifier module technology that combines a high-power Class D amplifier with a differential pressure sensor and zero-latency DSP. In the KS8, it enables precise driver control and high output efficiency from the integrated 8500 W amplifier module.
Is the Firenze-KS8 suitable for outdoor use?
Yes. The speaker enclosure carries an IP45 rating and the electronics module an IP65 rating, providing protection against water jets and dust ingress for outdoor concert and festival environments.
Can the KS8 be configured for directional bass output?
Yes. The onboard DSP supports input delay of up to 2 seconds and parametric filtering, enabling cardioid and end-fire arrangements. It is also fully integrated into EASE Focus simulation software for detailed system modelling.
