- Three-channel infrared system supports two microphones and one presenter remote simultaneously.
- 4 × 70 W at 8 Ω (4 × 130 W at 4 Ω) with outputs for up to eight speakers.
- Designed for classrooms and lecture theatres up to 400 m².
Overview
Key features
- Three-channel infrared system supports two microphones and one presenter remote simultaneously.
- 4 × 70 W at 8 Ω (4 × 130 W at 4 Ω) with outputs for up to eight speakers.
- Designed for classrooms and lecture theatres up to 400 m².
- Infrared sensors can be integrated into the loudspeakers, reducing separate sensor installation.
- USB camera input and a built-in digital sound card support lecture capture and online teaching.
- IPM power management and automatic sleep extend microphone battery life.
The kit is assembled from matched Seekika Audio components, so the receiver, microphones, charging cradle and speakers arrive as one tested configuration rather than separate parts.
Each kit is configured before delivery for the target room size and microphone mix. Contact Seekika Audio with the room dimensions and ceiling type for a configuration and deployment plan.
