KAMEHA KA235 Audio Extender 300M over CAT5e/6 Optical & Analog Audio Transmission with Bi-Directional PoC

Product Introduction

The KAMEHA KA235 Audio Extender 300M is a professional long-distance audio transmission solution designed for PA systems, AV installations, home theaters, multi-room audio systems, and commercial sound applications.

This high-performance audio extender transmits digital optical (SPDIF) and analog stereo audio signals simultaneously over a single CAT5e/6 cable up to:

• 300 meters (48kHz)

• 150 meters (96kHz)

• 100 meters (192kHz)

With built-in DAC (Digital-to-Analog Converter) and bi-directional PoC (Power over Cable) support, it offers a reliable, plug-and-play solution for professional audio system integration in Malaysia.

Product Description

The KA235 allows stable transmission of both optical fiber audio and analog stereo audio signals across long distances without signal degradation.

Key capabilities include:

• Optical digital audio pass-through from transmitter to receiver

• Selectable analog output on receiver (digital or analog input source)

• High-resolution audio up to 24-bit / 192kHz

• Ultra-low jitter and high-fidelity audio design

• Plug-and-play operation (no complex setup required)

This makes it ideal for extending audio signals from HDTV, media players, or digital sources back to:

• Amplifiers

• AV receivers (AVR)

• Multi-room audio systems

• Commercial PA systems
