Systembase is a leading supplier of professional digital audio codecs to many international TV and radio broadcasting companies. Systembase codecs have the lowest coding delays for realtime transmissions and live OB’s.Full duplex audio is provided at various bandwidths:3.7kHz dual mono(64kpbs) for programme communications, up to linear PCM for live music.
Systembase audio codecs include the C510ip, designed and manufactured to deliver unparalleled performance and reliability for professional real-time audio applications over ISDN, ADSL, IP and Satellite. The C510ip incorporates the fast apt-X Sub Band ADPCM compression system which can deliver a coding delay of only 2.8ms, in addition to Linear PCM, G.722 and G.711.
The C510ip is fully compatible with the existing C310xr ISDN codec when operating over ISDN and X.21 circuits. In addition, the C510ip also supports Dual G.711 and Dual G.722 coding to provide enhanced compatibility with ISDN codecs from other manufacturers. Additional design features include 24 Bit analogue and AES audio interfaces. The analogue interface is electronically balanced resulting in a high Common Mode Rejection Ratio (CMRR) for a significant improvement in performance.
Following a power failure, the C500 series of audio codec can fully reboot to the ready state in approximately 1 second.
