APT Oslo Duplex Analogue
There are over 15 different varieties of pre-configured, plug-in audio modules for the WorldNet Oslo. All modules provide an interface I/O board with standard XLR connectors. With up to 6 physical slots, a maximum of 24 simplex and 12 duplex connections are possible on a single frame.
Each module offers four audio channels which can be either four encode, four decode or two encode and two decode. Offering a high level of flexibility and channel density, the simplex modules can operate either as dual stereo or quad mono cards.
Based on a modular architecture, all WorldNet Oslo modules are “hot swappable” and can be changed without causing a glitch on any of the audio channels or affecting them in any way.
On synchronous networks, individual channels can be enabled and disabled or routed to two different destinations i.e. stereo A on the main E1 or T1 link and stereo B on the secondary / drop and insert circuit. On IP networks, the inputs of audio cards can be sent together to multiple destinations in multicast or multiple unicast applications.
Broadcast Grade Audio
Exceptional audio quality can be delivered using either Enhanced apt-X audio coding or the pure linear PCM/uncompressed option. The Enhanced apt-X audio format provides an operational audio resolution depth of either 16 bits or 24 bits while the digital circuits of the audio module run at a resolution of 24 bits (A/D - D/A converters, audio DSP etc). Using low delay, Enhanced apt-X at high quality 16-Bit resolution, the WorldNet Oslo can combine up to 6 fully duplex 15kHz stereo programs on a single T1 line or 7 on an E1 line.
Other coding and companding options available include G.711, MPEG 1/2 Layer 2, J.57 and J.41. These options provide the ability to employ the WorldNet Oslo in networks equipped with third-party codecs.
Phase-Matching for Surround Sound
6 duplex audio channels or 12 simplex audio channels, provided by three audio cards of a kind, can be phase locked in order to provide a true surround sound image for 5.1 Radio Broadcasts.
