ARRAROWN ZK-1002T PRO Bluetooth 5.0 2.0-Channel 2x100W Amplifier Board (2 Pack) with Treble & Bass Controls

ARRAROWN ZK-1002T PRO is a compact 2.0-channel Bluetooth 5.0 amplifier board delivering up to 100W per channel with treble and bass controls, USB/AUX inputs and protection features for DIY speakers and subwoofer setups.

This dual-pack amplifier module pairs modern wireless connectivity with adjustable tone controls in a small, mountable board designed for hobbyists, cabinet builders and small audio projects. It supports Bluetooth 5.0 streaming, USB audio playback and AUX input, while operating from a DC 12–24V supply. The board includes thermal, over/under-voltage and short-circuit protections and prints interface labels on the protective plate for straightforward installation.

How does the ZK-1002T PRO connect to my devices?

Connect wirelessly via Bluetooth 5.0 for stable streaming from phones, tablets and computers. You can also plug in audio sources directly using the USB or AUX inputs; note that AUX should be used with Bluetooth disconnected to avoid input conflict. The board outputs stereo to two speakers or can be integrated into a 2.1 subwoofer system with appropriate wiring.

• Bluetooth 5.0 for low-latency wireless audio
• USB input for media playback or connected digital sources
• RCA/AUX input for analog devices; disable Bluetooth when using AUX
• Dual-channel outputs supporting standard speaker wiring

What sound adjustments and quality features are available?

The module includes independent treble and bass adjustment buttons so you can shape the tonal balance directly on the board without relying on your source player. A high-performance amplifier chip, front-stage low-noise operational amplifier and power shielding reduce interference and keep distortion low at typical listening levels. These elements combine to deliver clear midrange and controlled low-end suitable for bookshelf speakers and compact subwoofers.

• Integrated treble and bass controls on the module
• Low-noise front-stage op-amp for cleaner signal path
• Shielded power inductance and AM interference suppression
• Designed for minimal audible distortion at normal volumes

How do I power and protect the amplifier safely?

The ZK-1002T PRO runs from a single DC supply between 12 and 24 volts, letting you use common bench PSUs, sealed lead-acid batteries or compact switch-mode adapters. The board includes multiple protective circuits — over-voltage, under-voltage, over-heat and short-circuit protection — and ships with a protective plate to guard components during installation. Follow polarity and voltage limits, and mount the module with adequate ventilation for reliable long-term operation.

• Operation voltage range: DC 12–24V
• Over-voltage and under-voltage protection circuits
• Thermal and short-circuit protection for reliability
• Compact footprint with labeled protective plate for easy wiring

How easy is the ZK-1002T PRO to install and integrate?

The protective plate has printed labels for each interface, reducing setup errors and letting even first-time builders wire the board without a lengthy manual. Its small size (4.4" × 2.75" × 0.78") fits inside most small speaker cabinets, portable enclosures or custom DIY projects. Mounting holes and clear terminal points speed up integration into finished systems.

• Labeled protective plate simplifies wiring and setup
• Compact dimensions fit inside small speaker enclosures
• Mounting-friendly layout for quick integration into projects
• Included protections reduce risk during bench testing

Who is this for: The ARRAROWN ZK-1002T PRO 2-pack suits DIY audio enthusiasts, small-scale speaker builders and hobbyists who want a feature-rich amplifier module for bookshelf speakers, desktop setups or compact subwoofer systems. It’s also practical for electronics tinkerers needing a reliable, tone-adjustable Bluetooth amplifier with straightforward installation and robust protection circuitry.
