About JK Audio Universal Host Desktop Digital Hybrid Telephone Interface

Let the JK Audio Universal Host Desktop Digital Hybrid Telephone Interface elevate your telephonic communications to a professional level with unparalleled ease and reliability. Designed to seamlessly convert your IP or PBX telephone into a high-quality interview station, this advanced interface ensures that you can conduct broadcast-quality interviews right from your desktop.

Experience crystal-clear caller audio that rivals talk show standards, thanks to the interface's ability to provide excellent separation between your voice and the caller's. The simple connection between your telephone handset and the base transforms your telephone into a powerful communication tool, perfect for capturing dynamic interviews with a professional microphone and headphones.

Ideal for conference room settings, the Universal Host effortlessly integrates your PA system with your existing IP or PBX telephone system. The built-in echo canceller algorithm works to prevent feedback and supports full duplex conversations, ensuring that your communications are both smooth and professional.

The 16-bit USB audio codec is a standout feature, enabling stereo recording at a high-quality 48kHz sampling rate. This ensures that your voice is recorded on the left channel with full audio bandwidth, while the caller's voice is isolated on the right channel. Additionally, you can play recordings from your computer directly into the phone system, adding versatility to your audio management.

The digital hybrid's sophisticated Digital Signal Processor (DSP) continuously monitors both transmit and receive audio signals, delivering exceptional audio separation. The proprietary dual-convergence echo canceller algorithm provides this superior separation effortlessly, without the need for complex setup or disruptive noise bursts.

Connectivity is a breeze with options for a microphone, headphones, mixer, sound card, and telephone handset. The stereo output jack located on the rear of the unit offers a dedicated channel for your voice and another solely for the caller's voice. The balanced XLR output jack is reserved for the caller's audio, ensuring a professional and isolated feed for recording or broadcasting.

Switching between handset and audio connection modes is straightforward with the Handset and Online buttons, while a secondary switch allows you to toggle between monitoring the caller or listening to the USB codec through your headphones. With its durable construction and reliable performance, the JK Audio Universal Host Desktop Digital Hybrid Telephone Interface is the professional's choice for superior telephonic communication and audio recording.
