General Detail:

DIGI-SYS Pro Dig. Audio 1200 is digital distribution amplifier used for distributing digital audio data in AES/EBU format including latest AES 3. It is economically distribute, audio signals in a broadcast station or a recording studio. The 1200 can drive one source to up to 12 destinations with excellent quality. The outputs of 1200 are through isolated drivers and transformers. This configuration allows outputs to be patched freely or drive long lines with clean signals.

DIGI-SYS Pro Dig. Audio 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.
