AxelTech PUMA FM Rebroadcast Receiver & IP Encoder

AxelTech PUMA is a professional FM rebroadcast receiver and Audio-over-IP encoder for transmitter sites, relay stations and broadcast networks. Its frequency-agile DSP tuner receives FM signals from 87.5 to 108 MHz, recovering a complete MPX signal that can feed an FM transmitter or another MPX distribution path.

Reliable FM Rebroadcasting with AxelTech PUMA

Designed for unattended broadcast installations, PUMA combines FM reception with built-in RF, MPX, audio and RDS monitoring. Engineers can check incoming signal quality, modulation and programme status locally on the front-panel display or remotely through the embedded web server. The unit also includes RDS decoding and UECP-format data output for RDS bridging and rebroadcast applications.

In addition to its analogue, AES/EBU and MPX outputs, AxelTech PUMA encodes received programme audio for network delivery. It supports UDP/RTP, TCP/IP and Icecast2 streaming, with OGG Vorbis and optional MP3, AAC, HE-AAC and HE-AAC v2 encoding. This allows stations to monitor the off-air programme remotely, feed a low-bandwidth backup stream or distribute received audio to other network locations.

Dual Ethernet ports, dual USB ports, RS-232 and four opto-isolated GPIs with four relay outputs support integration into broadcast control and monitoring systems. The receiver is designed for high immunity to strong RF fields, while a front-panel headphone output provides a convenient local confidence-monitoring point at the transmitter site.

AxelTech PUMA is a natural companion to the AxelTech Tiger E3/E5 FM site controller and MPX generator, which can provide transmitter-site control, MPX generation and RDS encoding. For programme processing before transmission, it can also be used alongside the AxelTech Falcon X5 audio processor. Where a dedicated bidirectional STL or studio-to-site IP link is required, the AxelTech Streamer Max MKII provides complementary full-duplex audio transport over IP.
