TDA7388 Class AB Power Amplifier with ADAU1701 DSP and PCM5102 DAC

Enovo-77 is a class-AB quad bridge amplifier with DSP. You can control TDA7388 amplifier with ADU1701 on-board DSP via SigmaStudio software. With on-board DSP you can add various crossovers, equalizers, effects to the amplifier. Along with on-board DSP, Enovo-77 also has a on-board PCM5102 DAC (digital to analog converter) connected to DSP's SDATA_OUT, MCLK & BCLK, which outputs Analog signal via AUX connector. You can program which output as Sub-woofer out or even stereo out and connect either a subwoofer amplifier or another Enovo-77 together to output 4.1, 4,2, 6.1, 8.0, 8.1 or 8.2 channel outputs.

Do More!

You can club together multiple systems to build 4.1 or more channel amplifiers. Connect DSP Board to the Digital Out from Master DSP on the amplifier which you can use to connect either TDA7388 4 channel amplifier along with TAS5828m Mono amplifier or directly connect Master DSP to TAS5828m.

Possibilities are unlimited!

System	Options	Difficulty Level
Stereo	enovo-77 You can either use only 2 Outputs from enovo-77 to run a stereo system or combine 2 left & 2 right channels for more power.	Plug-n-Play
2.1	enovo-77 You can 2 Outputs from enovo-77 to run left-right channel and combine 2 channels as Mono Sub-woofer.	Medium
4.0	enovo-77 You can either use each output from enovo-77 to run left-right Tribal & left-right Bass.	Plug-n-Play
4.1	enovo-77 + enovo-tas-5 You can either use each output from enovo-77 to run left-right Tribal & left-right Mid and use Digital Out from enovo-77 as Digital In for enovo-tas-5.	Pro
8.0	enovo-77 + enovo-77 You can use Digital Out from one enovo-77 (set as master) as Digital In for enovo-77 (set as slave) to run 8.0 syetem.	Pro
8.2	enovo-77 + enovo-77 + enovo-tas-5 You can use Digital Out from one enovo-77 (set as master) as Digital In for enovo-77 (set as slave) to run 8.0 system, additionally you can use Digital Audio from enovo-77 (set as slave) as Digital In for enovo-tas-5	Pro
