  • Class D design runs cool with high efficiency from 12 V to 24 V supply
  • Built-in protection circuitry keeps output silent when no signal is playing
  • Solid aluminium chassis provides rigid housing for low-noise home Hi-Fi use
  • Includes power adapter, AC cord and manual for immediate desktop setup

Compact stereo amplifier for passive speakers

The Fosi Audio V1.0G is a 2.0 CH Class D amplifier built around the Texas Instruments TPA3116D2 chip. It delivers 50W x 2 into passive speakers and accepts line-level sources such as a laptop, TV or game console. The unit ships with a 24 V power adapter, an AC cord and a user manual.

Sustained output with minimal heat

Class D topology and the TPA3116D2 oscillator design keep power loss very low across the 12 V to 24 V supply range. The aluminium chassis dissipates heat without a fan, so the amplifier remains silent during long listening sessions. THD is rated at 0.04 % and signal-to-noise ratio reaches 98 dB at the specified load.

RCA input limits and speaker matching

The rear panel provides only RCA inputs, so digital or wireless sources require an external converter. Output impedance range is 2–8 Ω; speakers outside this range are not supported. Maximum output power is 50W per channel, so systems needing higher continuous power or a dedicated subwoofer output will need a different amplifier.

Questions about this item

How much heat does the 50W x 2 TPA3116D2 Class D amplifier produce when running all day?

The ultrahigh power efficiency and cool operation make it suitable for continuous use in home audio systems with very low power loss under all operating conditions.

What audio source and speakers must I already own to use the RCA inputs and passive speaker outputs?

Connect any device with RCA line-level output — such as a PC, TV, or DVD player — and a pair of passive speakers rated 2-8 ohms.

Will the 12 V to 24 V supply range and 2-8 ohm impedance match work with older passive speakers I already have?

Yes, the amplifier supports a supply voltage range from 12 V to 24 V and a terminating impedance of 2-8 ohms, compatible with most legacy passive speakers.
