Description
The ASI4346 features multi-stream MP3 and MP2 audio playback, MP2 record, GPIO and an RS422 serial input, making it the most feature complete broadcast audio adapter in existence
The ASI4346 is a feature packed digital audio adapter with powerful on-board mixing, GPIO and direct bitstream inputs. The GPIO consists of eight relay outputs and sixteen opto-isolated inputs.
These enable the control of station equipment and sensing of news feeds and other events. Using a standard Windows multimedia control type, the GPIO may be accessed using Windows multimedia mixer calls.
A unique feature of the ASI4346 is the RS422 serial input.
This supports the direct input of a satellite receiver MPEG bitstream which can be recorded as a tandard .WAV or .BWF file for later playback. The ASI4346 removes the transcode and
analog-to-digital conversion process that typically occurs when recording network satellite feeds, improving the audio quality.
Three balanced stereo inputs and four MP3 or MPEG-1 Layer II playback streams can be digitally mixed to four balanced stereo outputs. One stereo MPEG-1 Layer II record stream can be sourced from any of the three inputs. 20bit over-sampling A/D and D/A converters are used to provide greater than 90dB of Signal-to-Noise Ratio (SNR) and less than 0.005% of Total Harmonic Distortion+Noise (THD+N) when recording or playing.
Signal quality is beyond reproach with Pro standard +4dB analog signals being supported with lots of extra headroom. Output can be adjusted down to -10dB consumer levels using the control applet if you want to interface to unbalanced gear.
