Tone Module M65831 T62M0001A Karaoke Reverb Board Preamp Board High Bass Adjustment DC 12V Power Supply Board Module

<ul><li>1. It Has Its Own Negative Voltage Conversion Circuit, Which Doubles The Power Supply Voltage And Has A Larger Dynamic Range And Is Less Prone To Distortion;</li><li>3. The Reverberation Part Refers To The Design Of Power Amplifier, Using Forward And Reverse Circuits To Stereo Reverberation.(If A Monophonic Power Amplifier Is Used, The Output End Can Only Be Connected To One Sound. If The Other One Is Left Empty, Must Not Be Connected In Parallel. This Cancel Out The Reverberation Signals, Resulting In Artificial Faults In The Music And Vocals Without Reverberation.)</li><li>5. The Positive And Negative Poles Of The Power Supply Are Protected Against Reverse Connection, The Static Operating Current Is About 100ma, The Gain Of The Microphone Part Is 37db, The Music Part Is 20db, And The Treble And Bass Adjustment Range Is ±12db.</li><li>2. The Delay Time Uses A Voltage Controlled Oscillator And A Potentiometer To Adjust The Time. It Is Much More Advanced And More Convenient Than The Switch Type Recommended By The Pdf, Haha! That Exceed Those Of Others On The Market;</li><li>4. The Stereo Music Amplification Part Has Treble And Bass Control, And The Two-Way Dynamic Microphone Amplification Circuit Has Volume Control And Treble And Bass Adjustment;</li></ul>
