Donner 5.1 channel amplifier with Bluetooth 5.3 and microphone inputs review

A 5.1 amplifier with two microphone inputs and echo — which places it between a home cinema receiver and a karaoke amplifier, and the page says which parts serve which.

The bottom line A five-channel amplifier rather than a receiver — cheap, well connected on the analogue and optical side, and without the HDMI that defines the category.

What it is, precisely

An amplifier with five channels and a subwoofer output, fed by optical, coaxial, USB, RCA, FM or Bluetooth. What it does not state is HDMI, which is what separates an amplifier from an AV receiver: switching sources, receiving audio over ARC, and decoding the formats those connections carry.

What that means in practice

Connected by optical from a television, it will drive five speakers and a subwoofer. It will receive compressed surround — the ceiling of the optical standard — and not lossless or object-based audio, because optical cannot carry them.

The microphone inputs

Two, with echo. That is a karaoke feature and it is stated plainly. It is a real reason people buy this class of product, and it is worth naming rather than treating as an oddity.

What is not published

A power figure with conditions. As across most of this catalogue, so the amplifier cannot be compared with a receiver stating W into 8 ohms.

Where it makes sense

A household that wants five speakers on a small budget, connected optically, with a microphone for occasional use. Where lossless surround and HDMI switching matter, this is not the shelf.

Availability

On sale at around 110 € on the German, American, British, French, Italian and Spanish Amazon stores at the time of checking.

The Italian and Spanish Amazon listings are priced above 1.6× the cheapest store, which is normally a reshipping offer rather than a local price; they are left out of the range above.

What we like, and what we don't

Strengths

  • Five channels and a subwoofer output at a fraction of the price of a true AV receiver
  • Optical and coaxial digital inputs, so a modern television can reach it
  • Two microphone inputs with echo, which is a genuine feature for the households that want it

Compromises

  • No HDMI stated, so it cannot switch sources or receive audio over ARC
  • No power figure with conditions
  • Without HDMI it cannot decode the modern surround formats a receiver handles

Questions people actually ask

Is this an AV receiver?

Not in the usual sense. It amplifies five channels and a subwoofer and it does not appear to switch HDMI, which is what a receiver is mostly for. Connected by optical from a television, it will drive a five-speaker system — and it will not handle the lossless or object-based formats an HDMI receiver does.

What do the microphone inputs change?

They make it a karaoke amplifier as well as a home cinema one. That is a legitimate use and it is worth being clear about: this product is designed for a household that wants both, and its feature list reflects that rather than a pure cinema priority.
