Product details

Overview

Meet the Herdio 4-Channel Bluetooth 5.0 Amplifier, a compact, adaptable unit designed to power multiple passive speakers across home, garage, or ceiling installations. With a total output of 200W (50W per channel), it can drive several speakers while delivering clean, stable sound over Bluetooth 5.0. The newer Bluetooth 5.0 standard aims to improve transmission speed and reduce signal loss over distance, while staying compatible with older Bluetooth versions.

Each Herdio amplifier can connect to four passive speakers at once, making it well suited for larger rooms or small multi-zone layouts. A built‑in TWS (True Wireless Stereo) mode lets two identical amplifiers in proximity stream to up to eight passive speakers simultaneously. When you want to revert to a single‑unit setup, the dedicated TWS button toggles the feature off with ease.

Key capabilities

  • 4-channel output enables multi-speaker configurations (50W per channel).
  • TWS function allows linking two units for up to eight speakers.
  • Bluetooth 5.0 offers faster pairing and stable streaming with compatible devices.
  • Multiple inputs: USB, MIC, and AUX for flexible audio sources.
  • Volume control is accessible directly on the amplifier for quick level adjustments.

Setup and usage

Installation is designed to be straightforward: mount on a wall or place on a table. Plan enough cable length to connect power and speaker wires without tension. The unit ships with a 19V3A AC‑DC power supply, mounting screws, a screwdriver, and a user manual, plus access to responsive support and a one‑year warranty with ongoing pre‑ and post‑sales guidance.
