Overview: Multimedia ICs Audio digital delay (KARAOKE echo) BU9252S / BU9252F The BU9252S and BU9252F are digital delays specifically for Karaoke systems. Each has an internal sample hold circuit, an 8-bit A / D and D / A converter and 2kB SRAM, and allows for the selection of one of eight delay times just by attaching an inexpensive ceramic resonator. A digital echo system can be formed by using either of these ICs together with the BA7725S or BA7725FS.
