The RX300A is a home theater receiver by Yamaha. It is a 5-channel design using a AB output stage. The Yamaha RX300A has an MSRP of $400.
Performance Specs
One of the most important factors when deciding on a home theater receiver is its power ratings and compatibility with your speaker's impedance requirements. The Yamaha RX300A is rated at 70 watts RMS into 8-ohms (2 channels driven).
Here are the main highlights of its performance specs:
How loud will 70 watts actually play in your room? →
Wiring more than one pair of speakers to it? Check the load first →
Need more power?
Yamaha RX300A is rated at 70 watts into 8 ohms, which puts it in our 61 to 90 watts band. The next band up is 91 to 120 watts, which is worth about 1.5dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room. Plenty of systems are better served by the Up to 60 watts band and better speakers.
When pairing the Yamaha RX300A with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
Inputs and Outputs
Besides the performance specs of the Yamaha RX300A, the next important feature set that you have to evaluate is the input and output selections that it offers.
Yamaha RX300A has total of 2 Analog inputs .
Inputs
- Total Number of Analog Inputs: 2
- 1 Optical Digital Input
- 1 Coaxial Digital Input
- USB Input
Outputs
- Speaker Outputs
- Subwoofer Output (Dual)
- HDMI Output (1)
Phono Input
Yamaha RX300A doesn't have a phono input so in order to play your vinyl albums, Yamaha RX300A has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
Surround Sound and Channels
Yamaha RX300A is a 5.2-channel receiver, powering 5 speakers directly - the .2 is 2 subwoofer outputs, not extra amplified channels. It decodes Dolby Atmos, DTS:X.
Video and HDMI
An AV receiver is the switch every source passes through on its way to the
television, so what it can carry sets a ceiling on the rest of the system.
- Pass-through: 8K/60Hz, 4K/120Hz
- HDMI version: 2.1
Yamaha RX300A Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓5 channels of amplification on board.
- ✓4 HDMI inputs and 1 output, HDMI 2.1.
- ✓Video passthrough at 8K/60Hz, 4K/120Hz.
- ✓Decodes Dolby Atmos and DTS:X.
- ✓Subwoofer outputs: Dual - more than one sub is the cheapest route to even bass in a real room.
- ✗The 70-watt rating is measured with two channels driven; expect less with every channel working, which is how a receiver actually runs.
- ✗No room correction system listed, which is the feature that does most for the sound in an ordinary room.

What amplifier class is the Yamaha RX300A?
The Yamaha RX300A uses a Class AB amplifier design. Class A/B is the traditional linear design: it runs warmer and is less efficient than Class D, but it is long valued for its natural, low-distortion sound.
Can I connect a turntable to the Yamaha RX300A?
No. The Yamaha RX300A has no phono input, so a turntable needs an external phono preamp (or a deck with one built in) before it can be connected.
Can I connect a subwoofer to the Yamaha RX300A?
Yes. The Yamaha RX300A has dual subwoofer outputs, so you can add a powered subwoofer to extend the low end below what your main speakers manage.
How much does the Yamaha RX300A cost?
The Yamaha RX300A has a manufacturer's list price (MSRP) of $400.
