- Analog to Digital and Digital to Analog conversion
- Supports CD, DVD, and Blu-Ray sample rates at 32kHz, 44.1kHz, 48 kHz and 96kHz
- Supports 2-channel linear PCM digital audio and 5.1 Channel Dolby Digital and DTS encoded bitstreams
- Delay up to 510 ms
- Delay calculation based on distance with optional automatic temperature compensation
The AD-340 is an audio delay processor with universal analog (L/R) and digital (SPDIF) inputs and outputs. Both outputs are simultaneously active, enabling conversion between analog stereo audio to LPCM or vice versa. Delay time can be specified in milliseconds, frames, or distance depending on the application. Analog inputs provide +/- 24 db of gain for direct connection of low level mic as well as handling 2vrms line-level signals. The AD-340's digital I/O support 2-channel linear PCM, 5.1 Channel Dolby Digital, and DTS Surround encoded bitstreams at any sampling rate from 32KHz to 96KHz.
For advanced control, the AD-340 connects to a PC via USB (cable included). No special USB drivers are needed and Hall Research provides a free software configuration utility available for download below. Advanced settings include:
