Miranda UAP-1783-3RU Eight channel universal audio processor
Miranda UAP-1783-3RU Eight channel universal audio processor - UAP-1783-3RU
The UAP-1783 is a high quality, 24 bit universal audio processor that can process up to eight discrete channels of audio. Inputs comprise mono/two stereo analog channels as well as two AES. Outputs are analog (four mono/two stereo) and two AES. The actual I/O combination depends on the rear panel installed. The UAP-1783 can be used as a standalone audio processor for discrete audio signals or can be combined with a wide range of video analog-to-digital, digital-to-analog video converters and digital frame synchronizer proc/amps. When working in conjunction with a video card the audio cards process embedded audio channels that have been de-embedded and can be re-embedded into the video signals. Two audio processing cards can be combined together to process a total of 16 audio channels. When combining any two cards together, all audio processing is synchronous and in-phase ensuring proper alignment and matched delays. A ribbon connector carrying audio, timing signals and metadata links the video card with the audio card(s).
