    I've had a few hours now (thank you backing track for delivery in 2 days;))
    and it pleasantly surprised me:

    - By its weight (less than 3 kg) and its reduced size.
    - Super nice look although very modern (so not the taste of everyone ...)
    - But it mostly by his silence !!!! nothing like the old peavey I had !!!
    - It does not heat, made it 5h is lit and clears 5 times less heat than my old peavey ... or my stereo amp !!!!
    - And the power that is ample for home studio use, and c what scared me, but there was not any problem of the margin.

    this is my second amp and frankly incomparable c,
    185 I think it is a very good investment, time will tell me if it aged well ...

    it features among RCA (asymmetric) and jack very (symmetric) and outputs terminals.
    LEDs indicate the incoming signal (green) and clip (red).
    it lacks the XLR even if the jacks are symmetrical.

    with the experience I resumes without hesitation and I strongly advice!

    EDIT:

    after 2 years of use I too crunches problems ... bad contacts ...
    it is very bizar because not li a particular channel.

    Good, but with a very short life span

    The right channel gave up on me after only one year. Luckily for me, the reseller replaced it for me even though I had no warranty anymore... It had expired some days earlier!
    But one year later the problems came back: Crackles and signal dropouts, both on the right and left channels. Very annoying for monitoring and listening.
    It seems to be a well-known issue of this product, which the resellers tend to keep to themselves...
    Despite its good audio quality, I advice you against it!
    I would certainly not buy it again.
    I would go for some active monitor speakers.

    alot of power

    I've had my Alesis RA 150 for about seven or eight years. It came into my hands in an unlikely fashion and I have been using it in a variety of ways since I got it. It is a compact dual channel power amplifier, good for power monitors that may be un powered, or for using it as an head for a bass or guitar cabinet. It has both XLR and 1/4 inch outputs to send to a cabinet or speakers and it also has connections for speaker wire. In the front of it there is a headphone jack and a power switch. It then has a volume knob for each channel with green and red LEDs to show output level and overloading. I have used this amplifier successfully in a few ways.

    I've had my Alesis RA 150 for about seven or eight years. It came into my hands in an unlikely fashion and I have been using it in a variety of ways since I got it.

It has both XLR and 1/4 inch outputs to send to a cabinet or speakers and it also has connections for speaker wire. In the front of it there is a headphone jack and a power switch. It then has a volume knob for each channel with green and red LEDs to show output level and overloading. I have used this amplifier successfully in a few ways. Right now I am using it to power a pair of Yamaha NS-10M studio monitors and it works flawlessly for this. In the past I have used it as a bass and guitar head by plugging my instrument into it and sending the amp to a speaker cabinet. While I didn't get as much juice out of it in this application that I would have liked, it did the job. I used it for mostly bass guitar as this worked much better than guitar. However, this unit is probably really designed to power studio speakers, and works best in this application. The price won't make you dig too deep, and I'm not sure you can find too many of these around, but if you can find one and need a compact power amplifier for your monitors, I definitely recommend it! While not extremely versatile in its use by any means, what it does do, it does it well and has a pretty good amount of power for a single rack unit. I recommend the Alesis RA 150 to anyone on a budget looking for great quality.

    I filed the notice to contradict the "Group MACH 3" and their sale catalog who say that this amp must be purchased for occasional use ....
    My amp (coupled with the MK2 passive speakers) runs at least four hours per day and normal (adjustable volume buttons noon). In addition, t last I recorded with friends in a pice non air-conditioned, open the window as little as there was decision-making voice. He turned over 10 hours a day and never overheated. I make him see all the colors for more than two and a half years and it still did not.

It DGIG-MK2-coupled to a sound that suits me is: there is "hot" and suddenly fits well trs jazz music, but it is also efficient in trs brightness (classical music). I took these two extremes in music (jazz and classical), knowing that I use it mostly on the music of "MIDI" rap and electro.
    I strongly advise pregnant with my cit before, the whole nine did not Exceeds 500 euros if we dbrouille bien.Je have only one regret, the connector (RCA or JACK June 35)

    This is a 100 watt amp around. I use it to power a pair of Yamaha NS-10M Studio. The sound is correct, the precision of the sound is correct, the neutrality is correct, the dynamic is difficult to say (especially with NS-10!) But the reliability is by no cons terrible. Only fake contacts! I bought it used and I guess it's because the seller has sold it: shame! Apart from a, it has a great look. Moreover, it is an amp that barely heats, despite the hours and heurres use. But makes me look good with these fake contacts ... Rsultat: I'll sell it and I do not know what I'm going for now, instead.

    Well, well, I may be the dcevoir expectancy at certain but it may be that the clown ptits Alesis does not even test the equipment before swinging in a box. I bought mine and I did not put more than two days before I realized that the right exit silent borked.
    It got worse in a month until the output is odd hacks and interrupt / Ractive the left during his ptags of lead, so impossible to work with an amp dfectueux at this point without tripping itself same .. the only solution I found: return this widget factory and work with the cabinet on the left only until the replacement ..

    I have 2 years for my Yamaha NS-10M, I'm happy but no more. It lacks a bit of momentum I think. As against the report is very neutral, very quiet and virtually no heat. However, it generates easily blast that is getting stronger (unless I ca or connectors) but it will spoil a few eardrums before realizing it.

    I recommend the low-budget souahite gain amplifier (very) silent spineless neutral and transparent sound without needing a lot of sound power. The value for money is in anyway interesting.

    EDIT from 03/05/2006:

    I have more worries of false contacts from the amp, ca me soule, I will be having PEIT change! :-( ...

    I made the acquisition of this amp for 1 month and so far no problems ... despite the price-o

    Still I find the connectors a bit fragile especially the terminals, not to over manipulate my review, however, always on connectivity, I like the gold-plated. At sound reproduction, nothing to say, no breath even at high volume. I use two monitors with ONE MK2 ALESIS and rendering is really good, well rounded bass, treble and bright end ... The signal remains pure even at high volume.

    I had an amp in Paravant monitoring LUXMAN 2 * 75 watts and the difference is there, especially in terms of signal linearity at high volume! The RA150 is much more efficient.

    Quality / price ratio......
