DEVA DB91‑TX Compact IP Audio Encoder

The DEVA DB91-TX Compact IP Audio Encoder is a second‑generation IP audio codec designed to convert audio signals into high‑quality compressed streams for STL, internet radio and remote contribution. It supports high quality HE‑AAC v1/v2 and MPEG‑1 Layer 3 encoding, plus uncompressed PCM, allowing broadcasters to choose between efficient low bitrate links and transparent audio transport.

The DEVA DB91-TX encoder accepts analogue stereo audio on twin RCA connectors and a digital S/PDIF input, then streams over IP as HTTP, Icecast or SHOUTcast source, or as an RTP multicast sender. Standard sample rates of 32, 44.1 and 48 kHz are available, with bitrates up to around 88 kbps for HE‑AAC, 320 kbps for MP3 and over 1.5 Mbps for PCM. Front‑panel LED bargraph meters and status indicators provide quick local checks, while a headphone output and spoken IP address on startup simplify installation. Configuration and monitoring are performed via a simple HTML5 web interface from any browser, and UPnP support helps discovery on local networks.

• Second‑generation compact IP audio encoder for broadcast and STL use
• HE‑AAC v1/v2, MPEG‑1 Layer 3 and PCM encoding
• 32, 44.1 and 48 kHz sample rates with wide bitrate range
• Analogue stereo input (2 x RCA) and digital S/PDIF input
• Icecast / SHOUTcast compatible TCP/IP streaming with up to 10 clients
• RTP multicast transmitter mode for contribution and distribution
• HTML5 web browser configuration, UPnP discovery and front‑panel level meters

The DEVA DB91-TX pairs naturally with the DEVA DB91‑RX Compact IP Audio Decoder, forming a compact same‑brand codec link for studio‑to‑transmitter paths, backup feeds and remote programme injection over IP networks.
