DAS-441A Audio Synchronizer with Embedding

Delay. Transcode. Embed. Lip-Sync. The DAS-441A is a multi-channel audio synchronizer and processor with reference quality 24-bit A/D and D/A conversion sampled at 96 kHz. When paired with any Integrity 400 Series or 500 Series video synchronizer, it eliminates lip sync errors by automatically tracking the video synchronizer delay. A fixed delay offset can be added to compensate for upstream A/V timing errors. Convert analog audio to AES, AES to analog, embed or de-embed. Each input channel can be routed to any output channel. The phase of the individual audio channels can be inverted. Independent tones from the internal 24-bit test tone generator can be routed to the outputs for channel identification. Maximum analog input and output levels are +28 dBu.

The DAS-441A is a modular card for Integrity system frames. Choose either a 1RU standalone frame or a 4RU higher-density frame with optional redundant power supply.
