There are 3 Emotiva amplifiers in our database. Below you can see the main specs of these amps.
Emotiva Power Amplifier Series
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Emotiva BasX A1 is rated at 200 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:
- 200 watts into 8-ohms (5 Hz-80 kHz)
- 325 watts into 4-ohms
- 112dB Signal to Noise Ratio

Which speakers suit the Emotiva BasX A1?
200 W into 8 ohms, 325 W into 4.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Emotiva BasX A1 is rated at 200 watts into 8 ohms, which puts it in our Over 180 watts band. That is the top band we cover, so there is no step up from here - if it is not enough, the answer is more sensitive speakers or a smaller room, not more watts.
When pairing the Emotiva BasX A1 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.
What size of room is the Emotiva BasX A1 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Emotiva BasX A1 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Are you nuts? |
| Small Room | Bad |
| Mid-size Room | Poor |
| Large Room | Good |
| Very Large Room | Good |
Inputs and Outputs
Besides the performance specs of the Emotiva BasX A1, the next important feature set that you have to evaluate is the input and output selections that it offers.
Emotiva BasX A1 has total of 2 Analog inputs .

Bluetooth Connectivity
Emotiva BasX A1 doesn't have bluetooth connectivity feature. In order to stream your music via bluetooth, the easiest way is to connect an external bluetooth receiver to your Emotiva BasX A1. Two bluetooth receivers that we recommend are the
iFi Zen Blue V2 and the
Audioengine B1.
Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
Phono Input
Emotiva BasX A1 doesn't have a phono input so in order to play your vinyl albums, Emotiva BasX A1 has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
Balanced connections
Emotiva BasX A1 has a balanced XLR input. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more the connection is worth. Whether a balanced connection also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same power either way, so it is worth reading the maker's own wording rather than assuming.
Emotiva BasX A1 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓200 watts per channel into 8 ohms is more than most rooms and most speakers will ever ask for.
- ✓Damping factor of 500 means a low output impedance and firm control over a woofer.
- ✓Signal-to-noise ratio of 112dB, so the amplifier itself should be inaudible between tracks.
- ✓A monoblock - one per speaker, so the two channels share no power supply and no chassis.
- ✓Balanced XLR inputs, worth having on a long cable run.
- ✓Made in USA.
- ✓Detachable mains lead (Yes).
- ✗Being a monoblock, you need two of them for stereo.
- ✗A power amplifier has no volume control and no input selection - it needs a preamplifier, or a source with a variable output, in front of it.

How much power does the Emotiva BasX A1 have?
The Emotiva BasX A1 delivers 200 watts into 8 ohms and 325 watts into 4 ohms, per chassis. This is a monoblock: a stereo system needs two. It increases its output into 4 ohms, so it has some headroom for harder-to-drive speakers.
Does the Emotiva BasX A1 use vacuum tubes?
No. The Emotiva BasX A1 is a solid-state amplifier - there are no vacuum tubes in it.
What amplifier class is the Emotiva BasX A1?
The Emotiva BasX A1 uses a Class A/B 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.
Does the Emotiva BasX A1 have a built-in DAC?
No. The Emotiva BasX A1 has no built-in DAC, so a digital source such as a streamer or CD transport needs its own converter, or you connect it over analogue.
Can I connect a turntable to the Emotiva BasX A1?
No. The Emotiva BasX A1 has no phono input, so a turntable needs an external phono preamp (or a deck with one built in) before it can be connected.
Does the Emotiva BasX A1 have Bluetooth?
No. The Emotiva BasX A1 does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.
Does the Emotiva BasX A1 have a headphone output?
No. The Emotiva BasX A1 does not have a headphone output, so headphone listening needs a separate headphone amplifier.
How much does the Emotiva BasX A1 cost?
The Emotiva BasX A1 has a manufacturer's list price (MSRP) of $569.
