AIYIMA Audio A3001 TPA3255 300W Subwoofer Amplifier HIFI Mono Power Class D Digital AMP for Passive Speaker Home Theater DIY
Product Description
The AIYIMA A3001 provides high-efficiency low-frequency power for home theater subwoofers and passive mono speakers. Powered by the Texas Instruments amplifier architecture, it offers excellent energy efficiency with very little total harmonic distortion, making it perfect for driving tough passive subwoofers or strong bookshelf or floor-standing speakers.
Designed with routing options, a front-panel toggle switch makes it easy to switch between SUB mode (which is a dedicated low-pass subwoofer amplifier) and PBTL/Mono mode (which is a full-range $20\text{Hz}. 20\Text{kHz}$ mono power amplifier). In SUB mode the front-panel cutoff knob lets you adjust the low-pass frequency filtering ($40\text{Hz}. 300\Text{Hz}$).
Key Features
Texas Instruments TPA3255 Chipset: Provides up to three hundred watts of power output into four‑ohm loads with high power efficiency and very low distortion (THD less than or equal to zero point zero three percent).
Dual Working Modes (SUB / PBTL Full‑Frequency Switch): Allows you to easily switch between driving a passive subwoofer and working as a full‑range mono speaker amplifier.
Adjustable Low‑Pass Crossover Control: Includes a front‑panel SUB FREQ adjustment knob that ranges from forty hertz to three hundred hertz, letting you match low‑frequency bass output to your room acoustics and main speakers.
Dual Subwoofer Output Support: Speaker terminals drive subwoofers directly and a dedicated three‑point‑five‑millimetre pre‑out jack allows you to connect an active subwoofer or another power amplifier at the same time.
Swappable Op‑Amp Sockets: Built‑in DIP‑8 operational amplifier sockets let you swap the stock NE5532 op‑amps for compatible alternatives, such as OPA2134 or MUSES02, to customize the sound.

Advantages
The SUB/PBTL mode switch gives you flexibility to use this unit with subwoofers or single mono speakers. It works well either way.
A dedicated low-pass filter ranges from 40Hz to 300Hz, which keeps the bass clean and prevents mid-range frequencies from interfering. This means tight bass without muddiness.
You’ll find both speaker output terminals and a 3.5mm pre-out on the back. That lets you connect two subwoofers at once, giving you control over your bass setup.
The DIP-8 socket is designed for swapping. Audio hobbyists can try op-amps to tweak the sound exactly how they want—just pop in a new one.
Even though it’s small and built with a metal case, this amplifier doesn’t skimp on power. It delivers up to 300 watts of low-end performance while taking up space on your desk or in your rack.
