«  good but ... »

Publié le 10/06/14 à 07:02
Value For Money : Excellent
24 fixed or variable filters, programmable between 1/5 and 1/80 1/10 1/20 octave

digital camera, but no digital i / o

no adjustment of gain or input output level


Tedious configuration.

I've had two years, an output scores, and I still need the doc to set it. It's like back in the 80s:

no LCD, dedicated diode even to different modes. Only 3 buttons per channel and according to their color, they mean one thing or another. And of course, if kept for 3 seconds, the function is different. Printing adjust a quartz watch ...

Fortunately the manual is well done, and it is written from the perspective of the user, not the engineer who designed the gear:

it describes the steps required to program it to a live, not the functions one at a time ... that's good.

and the camera is more logical. It's just the user interface that is abused (not to say shit). 4 or 5 more buttons, or LCD and the camera is just perfect.

and once set in the balance, it just works during the concert.


Filters work very well, and they react to one quarter of a turn, even in 1/80 octave.
It effectively suppress feedback

on the other hand, if too many filters operate at the same time, the sound becomes very unpleasant, metallic ...
Normal at the same time, 24 filters, although they are all set to 1/80 octave, it's still heavy damage.

And then the camera application to work between 0 and 10 db (it goes up to 18db, so its is -18 to -8 dB full scale)

suddenly, it is easily clipping if we set the input level cold balance, when the filters are setting.

So the quality is good, if one monitors what you are doing


I use it for 2 years, and I find it correct.

DSP is very good, very effective.

on the other hand, it lacks a lot of things on the front and rear.

1) of the knobs of input and output gain. (Found on all multi effects)

the main use of this rack is the output returns to the singers and acoustic instruments.

So the unit has to work at -18 / -8bd, it is adjusted it via the master. and then after, well he went to the back, and there can be more manage the overall level of returns except to insert an electronic stage exit. (Kind of a preamp that is not used, set to line-in, and just serves as a knob level).
or he must start to send to a channel strip when not in use, and put the DBX insert in this installment. It then sends the signal to return via the live release out, and adjusted the level fader.

2) a few buttons and LED or LCD 1 to better communicate with the user

Again, the setting is tedious, but live, it runs by itself.
but hey, sometimes not that much to do in the balance.
I make the sound of a cover band, zicos 7 + 4 singers / singers.
Between the director and stage manager assembly (all analog) and concerts begin at 19:00 for a drink, it was not always 2:00 balance, we are quickly running late.
And there zicos hallucinate when they see you out the instructions, (

3) digital inputs / outputs

In short: It's not bad for the price, this module, but be aware of its limitations and shortcomings.

If it again, I still testerais competition.
Behringer, I think so too, but I throw a look at Sabine in secondhand.
At the same time, less than 200 €, do not dream ...
