Reference Amplifier

Show full description »

The RA Series of reference amplifiers packs power. Plenty of it. But what has made these studio amps mainstays in recording facilities of all sizes is their ability to provide the kind of reliable, consistent power that you need for long, repeated use in the studio. The amplifiers in the RA series give you increasing degrees of crisp, strong power so your speakers last longer, your sound is clean and clear, and you don't miss important sonic details due to excess noise. Plus there's an advanced cooling system so they can run long sessions. If you're looking for dependable, stable operation from a studio amp, check out one of the amps in the RA Series. It might be one of the smartest investments you've made for your studio!

The smallest of the RA series, the RA-150, delivers 75 watts per channel at 4 ohms, no fan (for quiet operation), and very cool-looking signal LED's and level controls on the front panel. Perfect for any project studio!

Alesis RA150 Stereo Reference Amplifier Reviews


Alesis RA150 Review

Let’s start by saying the alesis studio is fantastic in almost every way.
150 watts of crystal clear sound at less than £100
There is no fan so the running of the amp is as silent as a mouse
My computer chair makes more back ground noise than this..
You have to press a key on one of the synths just to know it’s on.
The amp is perfect for any home studio, synth based or other...
Why bother with powered monitors when you can get an amp like this
And choose from loads of passive speakers for much less than any
Half decant powered monitors.
This amp plus say the Alesis Monitor One MK2 Passive speakers would cost
Less than £200 i would like to see anybody who could buy a powered monitor
Set that could cost this little let alone double this amount and they
Probably will still not sound as good as these.
If you are setting up your first home studio these will be the best thing you could possibly
Start with .would even be fantastic for the home dj
Best studio amp you can but for the money....
And if you are wondering about buying of dolphin ordered this on a Wednesday afternoon
Came at 8.15 the next morning how fast is that..
excellant service by dolphin

Price Matching

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Please fill in the following form to request a price match.

What prices we will match?

We will compare prices for new, direct from manufacturer items, excluding any add-ons, options, or other special features which may affect price.

The item must be new and must be the exact same make and model (ie, the same size, version, etc.).

Since our postage charges are lower than most of the shops, the comparison price must be a "delivered cost" to the consumer.

If we are unable to verify the previous condition, we will notify you that we require additional information to verify the Price Match request. Our goal is to make this policy simple and hassle-free. We are committed to responding to your requests quickly.

The price you have found must be the Internet Retailer's regular, advertised price for a current and available item. The price you found cannot be a closeout, discontinued, blemished, year-end, inventory reduction, or any other type of advertised sale price.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.
