KIT-DW-305 Wireless Classroom Audio Kit
A complete classroom sound reinforcement kit built around the DW-305 infrared amplifier, with room for two infrared microphones and a page-flipping presenter. The 2 × 70 W amplifier is sized for teaching rooms up to 200 m² and supports up to four speakers.
- Three-channel infrared design runs two microphones and one presenter remote at the same time, with no frequency pairing.
- 2 × 70 W at 8 Ω (2 × 130 W at 4 Ω) with speaker outputs for up to four loudspeakers.
- Built-in USB digital sound card and USB camera input for recording, video conferencing and hybrid lessons.
Overview
Key features
- Three-channel infrared design runs two microphones and one presenter remote at the same time, with no frequency pairing.
- 2 × 70 W at 8 Ω (2 × 130 W at 4 Ω) with speaker outputs for up to four loudspeakers.
- Built-in USB digital sound card and USB camera input for recording, video conferencing and hybrid lessons.
- IPM power management wakes microphones on movement and puts them to sleep after one second of inactivity.
- Two RJ45 sensor ports accept up to four remote infrared sensors for difficult room layouts.
- Feedback suppression and DSP tone adjustment are built into the amplifier.
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.
