Frequently Asked Questions about High-End Digital Amplifiers

What is digital echo?

A digital signal processor (DSP) is a device that processes audio signals entirely digitally. 

It receives analog signals (from microphones, CD players), converts them into digital signals (via an ADC ), processes them (anti-feedback, reverb, EQ balancing, etc.) using a DSP chip, and then converts them back to analog (via a DAC ) to output to the amplifier and speakers.

Why should you use a digital reverb unit instead of an amplifier with a mechanical echo effect?

Analog echo amplifiers can only adjust very basic effects (Echo, Delay, Repeat). Meanwhile, digital reverb allows for deeper control over each frequency range of both music and microphones through the Equalizer, managing frequency ranges for subwoofers and full-range speakers , and is significantly more effective at preventing feedback and howling. See also: Should you choose an analog or digital reverb for your karaoke system?

How to choose the right digital mixer?

You need to determine your needs: for home or business use? Do you need many ports? What is your budget?

For home karaoke, models like the E3 S7 and CAVS V850 are good choices. For higher demands or commercial use, the JBL KX180A and DMX DK9900 PRO would be strong contenders.

How does the anti-feedback function of a digital sound processor work?

Most high-end digital sound processors use frequency shifting or narrow frequency filters. When a repeated frequency is detected and amplified, causing feedback, the system will automatically shift that frequency slightly by a few Hz or use a filter to cut it out, eliminating the feedback loop without significantly affecting the overall sound quality. 

See also: How to adjust a digital sound processor to prevent feedback in a very simple way.

Can I adjust my digital sound processor at home myself?

You absolutely can! Most digital sound processors come with accompanying software for computers. You can learn how to adjust basic parameters like volume and echo/reverb effects yourself. However, to optimize the entire system and make in-depth adjustments to EQ, Crossover, and Limiter, you need more advanced software.

Reference: Guide to adjusting digital reverb manually and using a laptop.

What is the difference between a cheap digital mixer and a high-end digital mixer?

The difference lies in the quality of the components: the DSP chip, the ADC/DAC converter, and the processing algorithms. 

High-end digital sound processors use more powerful chips, allowing for more complex processing with high accuracy, and proprietary anti-feedback and reverb algorithms for a much better sound quality, less distortion, and cleaner audio. The higher price reflects this superior quality.

How does a digital sound processor improve sound quality?

Digital sound processors improve sound quality through four core elements:

1. Equalizing the frequency response of the speakers and the listening room through EQ helps to create a balanced sound.
2. Separating the frequency ranges for the subwoofer and full-range speakers via a crossover ensures that the speakers function correctly.
3. Achieve smoother, more expressive vocals with professional effects.
4. Eliminate background noise and feedback.

Do digital sound processors need a separate power amplifier (amply)?

Yes. A digital sound processor (DSP) is only a signal processing device; it does not have a power amplification function. Therefore, you must connect the DSP's output to a power amplifier, and then the power amplifier connects to the speakers. See details: Does a DSP need a power amplifier?
