General Detail:

DIGI-SYS ADA 2x12D is digital distribution amplifier used for distributing digital audio data in AES/EBU format including latest AES 3. ADA 2x12D economically distribute, audio signals in a broadcast station or a recording studio. The ADA 2x12D can drive one source to up to 12 destinations with excellent quality. The outputs of ADA 2x12D are through isolated drivers and transformers. This configuration allows outputs to be patched freely or drive long lines with clean signals.

DIGI-SYS ADA 2x12D has excellent performance and accepts AES digital signal carrier levels as low as 200 m volts and delivers full 5 Volt output drive which is free from all distortions due to cable losses. Input and outputs are through high quality digital transformers, eliminating hum completely. The unit is housed in a 1U 19″ rack mount chassis with power connections as per IEC recommendation.
