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.

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.
A 7.2 receiver from the house that states power with its conditions — the specification style that makes a receiver comparable to anything else that does the same.
Best for: A first proper surround system, with enough channels to add height speakers later without replacing the receiver.
A 5.2 receiver with an 8K-capable HDMI board — the board is what dates a receiver, and this one is specified for a resolution beyond what most systems will use.
Best for: A first 5.1 system where the budget matters and the HDMI board should not be the reason to replace it in three years.
7.2 channels · Dolby Atmos Height Virtualizer · gaming features · voice control · network receiver
A 7.2 network receiver with a height virtualiser — processing that produces height without ceiling speakers, and which the maker names rather than implies.
Best for: A room where ceiling speakers are impossible and a console is part of the system.
