  Audiofanzine FR's review

  Overall Opinion

  (Originally written by asseoa/translated from Audiofanzine FR)
  
  Introduction
  
  
  
  I've been owning two Dynamo 250 scans for one month.
  
  
  
  I used them for two events.
  
  
  
  I controlled them via a DMX software. (no music mode!)
  
  
  
  I had previously used other models but it's difficult to compare them because they were rented high-quality products (Martin).
  
  
  
  ------------------------------------------------------
  
  
  
  Summarized review:
  
  
  
  Pro: price!!!
  
  
  
  Pro: weight
  
  
  
  Pro: flightcase price
  
  
  
  Pro: nice gobos
  
  
  
  Pro: flood power and quality
  
  
  
  Pro: sweeping speed
  
  
  
  Pro: compact fixation system
  
  
  
  Con: only one wheel (gobos and colors not independent)
  
  
  
  Con: AC power socket on the bottom side (there's no way to place them upright...)
  
  
  
  Con: noise (but not louder than other models and it's inaudible once the music starts!) (I recommend you to use multiple socket outlets with power switches to avoid unnecessary noises before powering them up)
  
  
  
  Con: resolution!!! It's the major turnoff, in my opinion. I tell you why below.
  
  
  
  Con: strobe effect (more below)
  
  
  
  Con: impossible to switch between DMX and music mode via DMX programming
  
  
  
  ------------------------------------------------------
  
  
  
  Regarding resolution:
  
  
  
  It isn't really a problem in strobe mode or with fast movements!
  
  
  
  Every scanner has a "resolution".
  
  
  
  It's the number of steps per movement.
  
  
  
  The Dynamo 250 has 167 horizontal steps and 40 vertical steps.
  
  
  
  So when you do a sweep from left to right you can see the image "jumping" from one step to another. The further the image the more it jumps, and the more the effect quality decreases... ok?
  
  
  
  So what I mean is that this scan has not enough steps.
  
  
  
  But you'll be the only one to notice it during an event!
  
  
  
  Regarding the strobe mode:
  
  
  
  The problem is the strobe function:
  
  
  
  It alternates the chosen gobo and the previous gobo on the wheel.
  
  
  
  As a consequence, if you are on gobo 5 and you turn on the strobe you'll see the flood changing from gobo 5 to gobo 4 instead of turning on an off.
  
  
  
  The real strobe only works with gobo 1. (alternate gobo 1 / gobo 0 = no flood)
  
  
  
  Could it be that every scan has this problem? I don't know...
  
  
  
  ------------------------------------------------------
  
  
  
  Summary
  
  
  
  Good scans! Excellent for mobile applications.
  
  
  
  Light, easy to use, easy to transport in a flightcase, and affordable. I strongly recommend them!
  
  
  
  They'll bee a success at events!!!

  kikou03's review ( translated ) Improve this translation " SIMPLE AND VERY WELL"

  Overall Opinion

  How long have you been using?
  
  Since Christmas 2012 and 2 nights
  
  What is so special that you like most and least?
  
  + Small
  
  + Good light (with good lighting)
  
  + Beautiful colors
  
  + Dynamic (hence the name) very fast!
  
  Sacadant in very-slow motion
  
  But the fan noise with his music means more
  
  Ultrasound-
  
  -Very hot
  
  Did you try many other models before buying it?
  
  Never of moving lights
  
  How do you rate the quality / price?
  
  Very good a little disappointed not to have a gobo wheel and color wheel separated (at the same time are a price), they do the same jobs has side effects disco 300w
  
  With experience, you do again this choice? ...
  
  Yes, but I want a little more versatility of movement so I buy lyres, everything I RECOMMENDED amateur beginners to try this scan very cheap for what they do!

  Overall Opinion

  This is since April I use this scanner, very good price / quality ratio, good light with lamps philips lez colors are beautiful. Only weak point: no color wheel, mirrors and motors sacades a little when the gobo is not going very fast.
  
  In short, a very good buy.

  Djpinpon's review ( translated ) Improve this translation " Compact Simple and Effective"

  Overall Opinion

  How long you use it? I hosted two evening
  
  
  
  What is so special that you love the most, least?
  
  
  
  Goodies: Buy the pack 2scans CA8 Controller and fly to 389. Price vraiments friendly and nice effect. Simlple of use and low weight.
  
  
  
  Cons: I would say that there is very little to lemoment, this is brand new, except that the gobos tend to shake when you want to fix the beam.
  
  
  
  Did you tried many other models before buying it? At one time I had scans Martins, it's better now but it's more expensive ...
  
  
  
  How would you rate the quality / price? very good value for money.
  
  
  
  With experience, you do again this choice? Yes of aillor soon as possible I want to get two more ...

  flolight's review ( translated ) Improve this translation " Well"

  Overall Opinion

  I uitilise for almost a year.
  
  In concert for a small group and animation.
  
  It makes the job well.
  
  
  
  As:
  
  
  
  The price
  
  
  
  A minimum:
  
  
  
  No color wheel or rotating gobos but for the price ...
  
  
  
  Very good price / quality ratio!
  
  
  
  I did not have a scanner but before long I looked through the various catalogs ...
  
  
  
  I think I would do this choice for amateur use, is more than satisfactory.

  Squal 27's review ( translated ) Improve this translation " Effendi to the well for a small mobile disco!"

  Overall Opinion

  Hello I use since 2 years and I must say to the little room with some smoke and with ca 100personnes does its job!
  
  these are my first scans and I referred to review this site because I had not much use, but now I begin to go into the high-end applications therefore celon than 130 people move to 250 or 150 msd hti
  
  jaime although the rate of practical flight that carries two, the size of the scan is compact (it does not take too much space on the porch) and made good at the ba is the elc colors are not too early but when we are on the track we see the beams and gobos not
  
  solidity in it are strong enough to turn a little and put out a 23H 5H ca am shock!
  
  given the price and size for this qui'il are, beginner dj who may have less afford to buy directly from the msd I say go for it!
