ADA102 is able to work as Coder or Decoder, commutable by software. Full-duplex supported
for non compressed audio streaming.
Stereo balanced In/Outs -10 to + 15 dBu input level, regulated by front panel level control
Max output level + 20 dBm over 600 ohms (at FSD level) 0 VU at meter = +4 dBu out
Analog: 30 - 15.000 Hz +/- 0,5 dB @ 192 kbps
Digital AES-3: 20 - 15.000 Hz +/- 0,1 dB @ 192 kbps
Less than 0,01 % THD distortion, Analog or Digital @ 192 kbps
Distortion
Typical AES-3: 0,005 % @ 192 kbps Total Encoder+Decoder
Dynamic Range > 70 dBA @ 192 kbps as encoder
Noise
Dynamic Range > 80 dBA @ 192 kbps as decoder
Dynamic range AES 3: > 90 dBA @ 192, Total Encoder + Decoder
• MP3 Layer 1 (32, 44.1 and 48 kHz)
• MP3 Layer 2 (16, 22.05 and 24 kHz)
• G.711 (µLaw / A-Law 8 and 24 kHz sampling rate)
• 16bit PCM uncompressed (from 8 KHz to 48 KHz)
MONO Streaming: MPEG1/2 Layer 3, VBR (Fs:48KHz): 72 76 80 88 96 112 144 160kbps
STEREO Streaming: MPEG1/2 Layer 3, VBR (Fs:48KHz): 88 96 104 120 144 160 176 192kbps
IP standard based protocols; TCP/IP, UDP, HTTP, ICMP, SNMP
Protocols
Supports BootP, DHCP and Auto IP.
Supports RTP for low latency audio streaming.
The encoder uses Variable Bitrate Encoding (VBR) to realize optimal compression of the audio
data. The setting of a fixed bitrate is replaced with setting a quality level that preserves audio
quality in critical sections and enhances compression otherwise.
Bidirectional serial port RS232 used for Audio Processor control from studios, RDS signal control
or Transmitter remote control. Supports all speeds up to 96 Kbits/s
Used for switch on-off transmitter, change to Day-Nigth power, change antenna array, etc.
Four On-Off lines, 2 relay outputs (120 V - 1 A) and 2 open collector outputs (up to 24 V / 0,25
A ). In/Outs using D-15 female connector
In case of Internet streaming interruption, ADA102 starts to reproduce a pre-recorded radio
program. The user must record it on a Pen Drive, using MP3 format. The Emergency Radio
Program could be only music or a complete program several hours long.
