Audiofanzine FR's review

JB Systems Dynamo 250
(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!!!

Have you tried many other models before buying it?

Not of moving lights or DMX controllable

What is the particular feature you like best and least?

The single-wheel gobos / colored
+ Good power
-One of my machines moin enlightened than the other, I changed the bulbs but nothing has'm probably a manufacturing defect.
Very sacadants-Movement

How would you rate the quality / price?

Despite the good from errors

With experience, you do again this choice? ...

I will not point me to lyres for better versatility in terms of movement and accuracy

Gy67's review (This content has been automatically translated from French)" Good scan but restricted in use"

JB Systems Dynamo 250
Very good quality / price ratio is reliable right sixty output from 4yrs.
The original lamp has kept me 1 year for the two I have.
Well suited for use in automatic (master / slave) for very limited opportunities in manual operation.
Very hot but no surprises so far.
Think clean filters from time to time, it easily gets dusty.
I would do this choice if it is for the same use (auto).
Alternatively, for a small budget, ClubScan 250 electroconcept for use on software for me would be the next choice after his dynamo250.

kikou03's review (This content has been automatically translated from French)" SIMPLE AND VERY WELL"

JB Systems Dynamo 250
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!

JB Systems Dynamo 250
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 (This content has been automatically translated from French)" Compact Simple and Effective"

JB Systems Dynamo 250
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 ...

JB Systems Dynamo 250
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.

I like the special
- Their speed to their brightness they throw light the room as he is (still original lamps) I would like to do with how his French lamps will give as much stronger
- The musical program well in his slave master makes wonderfully beautiful

least in the music program too Strobe for my taste but I spend on computer dmx about it



product I recommend it to everyone early in the evening and although I dmx running with other DMX devices there are always present on the bridge
good value for money for only 129 euro
