ASI 6114
 The
new ASI 6114 is aimed at high performance broadcast applications requiring MP3
record and play with both analog and AES/EBU digital interfaces. The
ASI6114 uses a 150MHz Texas Instruments TMS320C6711 DSP and provides a powerful
multi-rate digital mixer. There are four discrete
stereo audio outputs and a stereo record input. Four
internal audio devices can be steered to any of the four physical outputs, which
can each be connected to a fader on your air board for maximum control of your
on-air playback. All analog outputs and inputs are balanced for maximum noise
rejection. Audio
format choices include MP3, MPEG Layer 2 and linear PCM.
The ASI6114 also has AES/EBU and S/PDIF digital audio input
and output for communication with other digitally equipped audio devices and
mixer boards, as well as having a powerful multi-rate digital mixer of its own.
Features
-
4 stereo streams of playback simultaneously, mixed to 4 stereo physical outputs.
-
4 stereo streams of Layer 3 (MP3), MPEG Layer2 or PCM playback into 4 stereo physical outputs.
-
4 analog and digital play outputs. 4 analog and digital inputs.
-
1 stereo stream of Layer3 (MP3), MPEG Layer2 or PCM record.
