JimboSpins's review"EQ on the fly"

Roland CM-30
The Roland CM-30 Cube only cost 220 bucks and has a 30 watt output. That is not bad for the money; it is also a powered monitor with a metal grill over it to protect it and a good handle to carry it with. Carrying it is not hard because it is not very heavy nor is it big. It only weighs 12 pounds and it is about 10 inches tall and 8 inches wide. You can mount it on a pole or use it as a floor monitor. The sound that it produces is clean and warm but it is not very big. There is not even power for it to be used in a big club or even a medium size club which leaves me to think where it can actually be used at?


There is no cross over frequency but it does have 3 input channels, only 1 of them is XLR and there are AUX inputs. This monitor is only for a small show or gig because you just cannot get a big sound out of it. If you are a traveling gigging musician then this could work great for you. For me I hardly ever gig as a musician anymore I just DJ now and this is no good to me anymore.


My favorite aspect of this monitor is the 2 band EQ on it that will allow you to control your low end and high end right from the monitor no matter where you are. Having EQ controls on the go is crucial with a small monitor like this because you always need to shape your sound to your surroundings. For the money, this could be one of the best 30 watt monitors you will find on the market for small gigging musicians. Also check out the Galaxy Hot Spot VC, it is very similar to this.

Roland CM-30
Rated power 30w.Ils are very convenient to carry everywhere can use monitors to listen and work on computer, so they are accurate enough to ça.En front three-way volume settings, and eq 2 voies.La sound quality excellente.Image stereo is good, clear and precise.Excellente dynamique.Avec the threaded hole in the box below you can attach a microphone stand, the linker has one of the other stereo effect, and have a small sound system, or be at ear level home studio on keyboards, for example (it is actually made for keyboards) he may collect the high level of attention when meme keyboards but the ears!
I do not have the frequency curve.
I use them since 2007 and we are in 2011; They are very solid probleme.Beaucoup never any friends who have seen and heard were also conquered.
A must have if you do not know what to buy as monitors for the same studio they listen peuve, nt do the trick.
New about 200 euros. (Note: 8/10)


Rating: 8/10 (In its category, ie monitors keyboard amps to 200 euros, ok?))


Rating 9/10 (still in its class)

Roland CM-30
What characteristics have motivated your choice?

The combo mixer / amp / hp all-in-one ergonomic carrying handle, the power / price and brand (manifested also in the price anyway ^ ^).
The types of available input, XLR, Jack 6.35 Mono / Stereo RCA Jack 3.5.

For what purpose?

We have 2 wired Stereo-Link associated with a PM-30 for sound to our rehearsal room for 2 guitars, bass, drums, vocals, keyboard, dj.


The frequency curve is sufficiently neutral?

It seems to me, but I'm not an expert and the walls of our ... cava are not ideal in terms of acoustics.

The stereo image is good?

Very good.

The sound is clear and precise across the spectrum?

He better not exceed 3 / 4 on volume knobs because the breath comes and low frequencies are beginning to saturate the amplifier and spit HP which seems dangerous to the longevity of the CM-30 but nothing abnormal for my taste.

The dynamics are respected? ...

I think yes.


For how long have you been using it?

9 months

What thing do you like most/least about it?

I love power. As in other reviews a bit by pushing to its limits "to see" one wonders "only 30W?" !
Like the small cable ties inseparable from the power cable that is useful to make a proper wiring
I love design, small but sturdy
I like the ergonomics and its handle
I love the idea of ​​stereo and Stereo Link
Like entries in a mess (3 mixable and 2 assistants)

Did you try many other models before getting this one?

Marchal up the Fender and 25W, the Peavey Bandit 112 but this is not the same range, the sound-medal assholes galore and all kinds of hifi (Sony, JBL, Bose).

What is your opinion about the value for the price?


Knowing what you know now, would you make the same choice? ...

Yes, and just to enjoy the stereo two CM-30 are worth much better than one.

Roland CM-30
I was looking for an amp for my acoustic Fender Stratacoustic thinking point me to a Marshall. Unfortunately, the date my old store had none in the price range that suited me. He showed me the amp with 15 watts max often between one while I intended to use it for voice as well.
He then showed me this so-called 30 watt monitor sduit me by its size and connectivity than complte


As in the opinion Previous I t bluff by his power! Before me who used a Peavey Bandit 112, I found the power / size silent far in the favor of the small cube.
The sound is silent in my expectancy at all to the extent I do not use effects pedals and then through (and I do not know yet INTEGRATED amp with loop station .. .). Of course, pushed back, low saturate and it becomes more noise and draft. But only when pushed to its limits.


I use it for over a year now and I associated a second there are about 6 months. The effect is much stro apprciable when I use it as sound btement home.
Then the strong points are the size / power ratio and connectivity. Of course the sound is also fte for its transparency and the versatility it offers.
Level qualitprix report, I'm not as good as Harley Benton and Behringer in this area but none offer such a product. Due to its rather unique characters while a reasonable price, so I Whereas trs as good!
I remake it as I conchoidal dj made by buying a second. If you do not test enough proximity to you, trust you seek a truly portable amp for any type of acoustic instrument, or even as a monitor / speaker amplifies.

Roland CM-30
A new cube for a multipurpose use, in line with the roland cubes. I do not is absolutely not pregnant monitoring (and I really think he did not t think why). I think its place should be in the CATEGORY keyboard amp.

Rated Power Output 30W

Dimensions214 (L) x 228 (D) x 275 (H) mm
Weight 5.6 kg / 12 lbs 6 oz

* 0dBu = 0.775Vrms
connectivity fairly complete, with the possibility to linker 2 cubes and thus have double the input and Stereo, unlike all existing keyboard amp.
pregnant magntiquement blind (always has) and construction trs trs solid. the hp is I do not know what alloy and being protected by a grille. I think short enough indestructible

should any musician looking for an ultra portable solution lgre fast setup and install. its versatility allows it to be useful in all cases I have come across in a semi acoustic concert:
sound sampler, voice, clarinet, keyboards, etc..
Brief all good.


Then it's incredible.
POWER HALUCINANTE for a cube of this size! "Officially it is 30 w, I do not really know how it's possible. The rendering of the trs is really good, and you really do saturate (low end) to hear the distortion.
I would definitely suggest trying it


I use it since it came out (mid 2005).
I Bourlingue the breaststroke in every corner or I will and in all times and no problem. it is for me the essential product for this use, due to its solidity and its quality sound mobility. I highly recommend all to buy two keyboardists plustt one keyboard amp, much heavier, but can STREO rpartition or sound in a room.
I think I try a little prs all that existed in this type of product, and trs far is the best.
quality price ratio: current average price 180 euros. Regard the price of the speakers amplified low-level RMS (I do not mean the quality or keyboard amp (and fool quality Roland also) ... the CM30 is related quality amazing price.

I do it again this purchase with eyes closed.
exellent product really is, but it does not replace a sound complte. in short, do not ask him to do what it does not pens. but in return, individual sound (in Stereo for small concerts) or nomadic complmnt for any purpose, it is extraordinary

Roland CM-30
I bought this amp for a little more volume on my keyboard because I was a little bit just to play with a colleague on guitar. For this utlisation there I am fully satisfied. However in my opinion is not utlise to cover a battery. The one side while I was also seduced (equalizer and amplifier).
I use it in mono.


The sound is good, transparent, and therefore ideal for a keyboard.
attention if we push the settings to the above average level (volume, treble, bass) of the breath is coming. over 3 / 4 breath is unbearable and the sound disgusting.
So in my opinion only use to play with another instrument and a singer in a small or medium room.


Utlisation for personal or small a group, this little amp is ideal. The sound is transparent, neutral. Easy to carry with its integrated handle, a small easily transportable. I have not tested the microphone and connecting with a reader.
