Hi-fi Stereo Bass Treble with Active Volume – PCB only

Hi-Fi Stereo Bass Treble Control with Active Volume PCB Board (Bare PCB)This PCB is designed for building a stereo pre-amplifier with active volume control, bass and treble adjustment, and onboard power supply rectification. Performance depends on components used and assembly quality.Working Voltage:Input: 12-0-12 VAC, 1 A to 2 A (step-down transformer recommended)Onboard rectifier and regulators generate required DC supplySignal Processing:Active volume control (linear response compared to passive controls)Bass and treble adjustment: up to ±15 dB (depends on component values)Signal gain: up to 20 dB (depends on configuration)Op-Amp Compatibility:Supports NE5532, JRC4558, TL072, NJM4560, LM833, OPA2160Separate op-amp configuration for each channelFeatures:RF input filter for reduction of unwanted noiseOnboard regulated power supply sectionSuitable for powering external modules such as Bluetooth or USB audio players (depends on configuration)Connectors:2.54 mm JST / Relimate connectors for input, output, and power connectionsBoard Specifications:PCB dimensions: 115 mm × 80 mmCompact layout for enclosure integrationConstruction:Bare PCB (components not included)Designed for through-hole componentsConfiguration:Compatible with audio amplifiers using ICs or discrete transistorsFinal performance depends on component selection and assembly qualityIncluded Support Material:Bill of Materials (BOM) includedAssembly and connection instructions providedIntended Use:Pre-amplifier stage for audio amplifier systemsBass and treble control in stereo audio systemsIntegration with amplifier and audio source modulesDIY audio and signal processing projects
