IP Controller (4 Channel) – KS Series (KS-707)
The KS-707 IP Controller (4 Channel) is a professional rack-mounted network control unit designed for multi-channel IP public address systems. Supporting independent IP audio decoding on four channels, relay-based device control, and remote power management, the KS-707 is ideal for centralized PA control rooms, factories, campuses, transportation hubs, and large-scale distributed audio systems.
Products Description
- 19-inch rack-mount design: Standard 1U height (44 mm), fully compatible with standard rack cabinets and control racks.
- Static IP configuration: Fixed IP addressing ensures stable and predictable network deployment, independent of DHCP services.
- 4-channel independent IP decoding: Four RJ45 network input ports, each with its own IP address, enabling independent IP audio streaming and decoding.
- High-quality audio processing: Supports MP3 / MP2 decoding with adaptive bitrates, delivering clear, CD-equivalent audio quality.
- Flexible audio input/output: Mic and line inputs combined with RCA stereo output allow seamless integration with mixers and amplifiers.
- Remote device & power control: Built-in AC power outlet and network-based on/off control for connected external amplifiers or devices.
- Advanced control interfaces: Four dry-contact relay outputs support triggering and controlling external systems such as alarms, lighting, and access control.
