STUDIOFINIX 4-Channel Mini Amplifier Bluetooth 5.0

STUDIOFINIX 4-Channel Mini Amplifier is a compact multi-zone amplifier that streams Bluetooth 5.0, accepts USB/MIC/AUX inputs, offers app and infrared remote control, and remembers settings after power-off.

If you need a small but capable amplifier for ceiling, wall, bookshelf, or garage speakers, this STUDIOFINIX unit lets you run up to four passive speakers with flexible source routing and simple controls. It pairs Bluetooth 5.0 wireless audio with a dedicated mobile app (PiLink) for zone assignment and fine-tuning, while an infrared remote provides quick access without a phone. The amplifier supports TWS pairing so two units can work together for larger setups and includes mounting hardware and a power supply for quick install.

How do I control audio zones and inputs from my phone?

The PiLink mobile app enables direct control of input selection, volume, and zone routing from iOS or Android devices. You can assign any connected source to any of the four channels and save settings so the amplifier returns to your preferences after power loss.

• Assign USB, AUX, Bluetooth, or MIC to individual zones via PiLink.
• Save presets and retain last settings with power-off memory.
• Use the app for smooth volume balancing across four channels.

What wireless and wired connections are supported?

This amp covers common connection needs: Bluetooth 5.0 for robust wireless streaming, plus physical USB, microphone, and AUX jacks for wired sources. Bluetooth 5.0 improves range and stability over older versions and remains backward-compatible for broad device support.

• Bluetooth 5.0 for higher throughput and improved connection range.
• USB input for direct playback from compatible drives or devices.
• MIC and AUX jacks allow announcements, karaoke, or wired players.

Can I expand the system for more speakers or larger spaces?

What installation and daily-use conveniences should I expect?

For everyday use you can choose app control, the included infrared remote, or physical source selections on the unit. Power-off memory restores your last configuration, so the system behaves predictably after power cycles.
