XH-M164 NE5532 Stereo Tone Control Preamp Board, 4-Way Treble Mid Bass Volume Adjustment, Dual AC 12-24V Audio Preamplifier Tuning Board

Description

Product Overview

XH-M164 tone control preamp board adopts dual NE5532 high-fidelity op-amps as the core audio processing chip, realizing independent adjustment of treble, midrange, bass and master volume for stereo audio signals. Standard RCA stereo input, 2.54mm 3P terminal audio output, designed for matching with power amplifier boards. Powered by dual AC 12V~24V alternating current transformer, low noise circuit layout restores rich audio layers, widely used in DIY HiFi audio systems, home speaker modification, car audio upgrade and audio equipment development.

Core Product Advantages

Dual NE5532 Hi-Fi Op-Amp, Clear & Layered Sound
Classic NE5532 low-noise operational amplifier, excellent dynamic range and low distortion, effectively suppress background noise, restore delicate vocal details, full and thick bass, bright and transparent treble.
4 Independent Tuning Knobs, Full Sound Customization
Four 50K linear potentiometers for separate adjustment: Treble / Midrange / Bass / Master Volume, freely shape sound style to match pop, classical, rock and other music genres. 24mm knob spacing, convenient for panel installation.
Dual AC Wide Voltage Power Supply Design
Support dual AC 12V~24V transformer power input, built-in complete rectifier filter circuit, stable power supply ripple suppression, power consumption only 5W, low heat during long-time operation.
Standard Audio Interface, Easy Matching

Input: Dual gold-plated RCA jacks for stereo signal access (phone, DAC, Bluetooth receiver, CD player)
Output: 2.54mm pitch 3Pin terminal cable, directly connect to post-stage power amplifier board

Complete Installation Accessories, Easy DIY Assembly
Comes with 4 blue knob caps, fixing nuts and gaskets, reserved M3 mounting holes (53×93mm hole spacing), easy to fix inside audio chassis.
Optimized Low-Noise Circuit Layout
Independent ground separation design, multi-stage electrolytic capacitor filtering, reduce cross-interference between left and right channels, no obvious hum even at high volume.

Full Technical Specifications

Parameter	Detailed Data
Main Chip	Dual NE5532 Operational Amplifier
Power Supply	Dual AC 12V ~ 24V Alternating Current Transformer
Static Power Consumption	5W
Audio Channel	Stereo Left + Right
Adjustment Functions	Treble / Midrange / Bass / Master Volume 4-way independent control
Input Interface	Dual RCA female stereo audio input
Output Interface	2.54mm pitch 3Pin terminal output
PCB Size	100mm × 60mm (excluding knob extension)
Potentiometer Spacing	24mm
Mounting Hole Spec	M3 screw, hole distance 53mm × 93mm
Matching Accessories	Knob caps, fixing nuts, gaskets, output connecting wire

Wiring & Operation Guide

Power Wiring: Connect dual AC transformer output wires to the board’s AC power terminals, distinguish dual alternating current without positive/negative polarity.
Signal Input: Plug audio source RCA cable into the left/right input jacks of the board.
Signal Output: Connect the matched 3P output wire to the power amplifier board’s audio input terminal.
Sound Tuning: Rotate four knobs to adjust volume, treble, midrange and bass according to listening preference.

Application Scenarios

DIY HiFi combined audio system, desktop lossless music playback set
Modification and upgrade of passive speakers, old audio amplifiers
Car audio host front-stage tone adjustment upgrade
Student electronic audio circuit experiment, op-amp preamp learning project
Small commercial audio equipment, public broadcast pre-processing module

Important Usage Notes

Must use dual AC transformer power supply, DC single power supply cannot drive the board normally.
Do not input AC voltage higher than 24V, excessive voltage will burn the op-amp and filter capacitors.
For long-distance audio input wiring, use shielded RCA cables to avoid external electromagnetic hum interference.
The board is only a preamplifier tone adjustment module, must be matched with a post-stage power amplifier to drive speakers.
Minor color differences of PCB and components among batches will not affect tone adjustment and sound quality performance.
