Audiofanzine FR's review (Dynamo 250)

By Audiofanzine FR, 09/03/2009
(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!!!
