ADA102 Coder / Decoder Technical Specifications, version II
Coder / Decoder Mode	ADA102 is able to work as Coder or Decoder depending on the software loaded. The client is able to change this software from a PC or laptop. Using non compressed PCM signals, ADA102 can work bidirectional (full duplex)
Analog Input / Output	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
Digital IN / Out	AES 3 professional balanced digital stereo IN / Out Z=110 Ohms. Full compatible S/PDif
Frequency Response	Analog: 30 - 15.000 Hz +/- 0,5 dB @ 192 kbps Digital AES 3: 20 - 15.000 Hz +/- 0,1 dB @ 192 kbps
Distortion	Less than 0,01 % THD distortion, Analog or Digital @ 192 kbps Typical AES 3: 0,005 % @ 192 kbps Total coder+Decoder
Noise	Dynamic Range > 70 dBA @ 192 kbps as encoder Dynamic Range > 80 dBA @ 192 kbps as decoder Dynamic range AES 3: > 90 dBA @ 192, Total Encoder + Decoder
Headroom	Safety level from 0 VU meter to Full Digital Scale: 15 dB
VU meter Level	Measures true peak level with a peak-hold system
Channel Separation	Better than 70 dB @ 1 kHz, Analog Better than 90 dB @ 1 kHz, Digital AES 3
Power supply	220-240V / 110 - 127 V 50 / 60 Hz, 15 VA

Digital Streaming & Control signals
Streaming connection	Standard RJ45 Ethernet connection TCP/IP
Standards supported	• 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 (8,16,32,44.1 & 48 kHz) Full duplex (transmitting and receiving) 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
Protocols	IP standard based protocols; TCP/IP, UDP, HTTP, ICMP, SNMP • Supports BootP, DHCP and Auto IP It supports RTP for low latency
Latency (time delay)	ADA102 has a latency of only 50 - 100 mS
Variable Bit Rate (VBR) Encoding	The MP3 encoder uses Variable Bit rate Encoding (VBR) to realize optimal compression of the audio data. The setting of a fixed bit rate is replaced with setting a quality level that preserves audio quality in critical sections and enhances compression otherwise.
RS 232 port	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
4 channels remote control lines	Used for switch on-off transmitter, change to Day-night 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
Emergency Radio Program	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.

Total Delay of two ADA102 units ADA102 connected to a standard Ethernet LAN of 100 Mbits/sec

Type of use	Speed Kbits/sec	DELAY (analog or AES) Milliseconds	Comments
uLaw MONO	64	60-90	Use only for return voice to remote journalist
MPEG1 Stereo	118 - 192	150	For high quality STL link using Internet
MPEG 2 Stereo	80 - 130	250	For STL link using Internet with reduced wide band
PCM 32 Khz Stereo	1.024	40	Recommended for high quality FM link between studios or STL link connected with fiber optic
Delay using 5,8 GHz microwave 802.11 link
PCM 48.1 kHz Stereo	1.411	30 - 50	Delay of ADA102 is less than 5 mS. Using 20 mS buffer total delay is < 30 mS

MPX output specifications model ADA102mpx
MPX Output	Differential output, BNC connector, floating ground 50 ohms Allows 45 dB canceling buzz & noise due to ground loops Level: Adjusted 0,5 to 4 Vpp from rear panel preset
Total Distortion	THD less than 0.003 % at 1 kHz.
Stereo Separation	75 dB at 400 Hz / > 70 dB; 30-15.000 Hz.
38 kHz Suppression	75 dB minimum below 100% modulation.
57, 76 and 95 kHz Suppression	75 dB minimum below 100% modulation.
Pilot Level	Adjusted 7-12 % from rear panel preset control
Pilot Stability	+/- 0.05 Hz, 0 to 50 °C.
