Quick Overview

This echo delay/reverberation circuit is based around the new PT2399 echo audio processor Integrated Circuit utilizing the latest CMOS Technology and equipped with ADC and DAC with high sampling frequency. An internal memory of 44K is used to generate a delay time of up to a maximum of 342 ms easily adjustable by an onboard potentiometer. The circuit also offers very low distortion (THD < 0.5%) as well a low noise (< –90dBV), thus producing high quality audio output suitable for many types of applications. The circuit incorporates both delay and repeats adjustments. An optional custom enclosure is also available with silk screened panels (Part # BX-128).

Popular applications are for Karaoke, Audio Equipment, Music Instruments, Public Announcement Systems, and many more.

Supplied assembled, also available in kit form.
