The Barix Exstreamer 100 is an IP audio decoder that receives digital audio streams over the network and converts them into an analogue audio signal, which can be connected to amplifiers or speakers. The device is designed for use in professional sound systems, particularly in areas such as broadcast, internet radio, and VoIP applications. It supports a variety of audio formats and network protocols, enabling flexible integration into different technical environments.

Applications

The Exstreamer 100 is suitable for applications where digital audio must be transmitted over IP networks and played back locally. This includes, among others, internet radio broadcasts, VoIP telephony, background music systems in shops or public spaces, and professional transmission systems in the broadcast sector. Support for various encoding methods enables use with different streaming sources and servers.

Functions and Features in Detail

The device decodes IP audio streams and provides an analogue output signal via RCA sockets and a 1/8″ jack connector. The output power is software-controlled and adjustable, allowing flexible adaptation to different amplifiers and speakers. The output impedance is between 40 and 60 Ohm, suitable for compatible connection to standard amplifiers. The maximum output signal is 5.6 dBu (4 Vpp), providing sufficient signal strength for operation with professional amplifiers.

Technology Explained Simply

The Exstreamer 100 features an Ethernet connection with an RJ-45 socket and integrated Link/Activity LED, enabling network connectivity at 10/100 Mbps. Supported network protocols include TCP/IP, UDP, RTP, SIP, and DHCP, allowing easy integration into existing networks. Power supply is via a 2.1 mm hollow pin connector with a voltage of 9 to 30 VDC or 12 to 24 VAC, with a maximum power consumption of 6 W. The audio decoder function supports formats such as MP3 (CBR/VBR up to 320 kbps, 8–48 kHz), AAC, AAC plus, AAC-HE, WMA (up to version 9), Ogg Vorbis, PCM 16 Bit (at various sampling rates), and G.711 (μLaw, aLaw). The frequency response is 19 Hz to 22 kHz (±3 dB), ensuring clear reproduction within the audible range. The dynamic range is 87 dB, and the signal-to-noise ratio (SNR) and distortion (THD) are below -87 dB and below 0.05 %, respectively, indicating high audio quality.

Compatibility and Accessories

The device can be used with accessories for rack and wall mounting, allowing flexible integration into various installation scenarios. The RS-232 interface enables serial control with baud rates from 300 to 230,400, which can be used either for local control or for tunneling. The aluminium housing construction ensures a robust and compact design, weighing 250 g with dimensions of 108 x 38 x 78.7 mm.

Installation and Mounting

Installation is performed over the network, with IP address and network settings configured via DHCP or manual setup.

Operational Advantages

The Exstreamer 100 offers a reliable and flexible solution for IP audio playback. Support for many audio formats and network protocols enables broad compatibility with various streaming sources. The software-controlled volume control and high audio quality (87 dB dynamic range, <0.05 % THD) ensure clear and clean reproduction. The compact design and options for rack or wall mounting make the device suitable for professional installations.
