Introduction

DF-PLUS is a high-performance general-purpose effects module with onboard SDRAM, implementing a dual-engine 99-effect processor. Each effects engine features independent ultra-long delay time and ultra-large reverb space. The module integrates an AKM AK4619 audio ADC/DAC, and uses an ATJ2853 Bluetooth chip from Zhuoxin (Actions Technology) for accompaniment audio, supporting Bluetooth v5.0. The module also provides 48K/24BIT full-duplex asynchronous sound card functionality, housed in a standard DIP36 through-hole package with a 2.54mm pitch. This module series is dedicated to analog mixing consoles, incorporating the BETFX audio algorithm suite — including ECHO, Delay, Chorus, Flange, and Reverb — suitable for vocal performance and live instrument applications.
