dbx DriveRack PA2 Acoustic Output Multi-Processor

時間に余裕のない現場でのチューニングには最適です。 AutoEQも3〜4分で済みます。 AutoEQ後は音のピントがバシッと決まった感じになり、各楽器のEQが凄く見えやすくなります。 以前、レビューでの評価がかなり良かったBEHRINGERのDEQ2496を使ってみましたがどうもピンときませんでした。 あれなら耳でチューニングした方がまだ良い。 買って損はない1台だと思います。

I really love how much control I have over my loudspeaker components now. So much more loud and clear sound. Will give your cheap PA speakers premium sound.

Calidad

Le fait de passer d'un signal ligne à un signal balanced, multiplie par 4 le voltage et avec deux signaux inversés, efface une partie commune des parasites. Ensuite j'ai utilisé un micro behringer ecm 8000 de mesure pour égaliser, l'avantage de faire cela est de supprimer les fréquences soit résonnantes dans la pièce, et de baisser les frequences ou les HP produisent un son agressif. Après ce traitement le son est propre, et n'occasionne plus de fatigue à l'écoute même à fort volume. Je conseille le réglage "reflective room" dans tous les cas ou la pièce n'est pas traitée avec des absorbants acoustiques, l'effet est plaisant. L'imaging et le stage sont très bons après traitement, meme avec du materiel mediocre derrière en terme d'ampli et d'enceintes. Un signal fort et qualitatif fait des merveilles (mais pas de miracle).

I am an active performer, and sound man, and have been so for over 10 years. I could start by saying that if you do not understand Equilization, Crossovers, Compressors, and Limiters you should not buy this product. I could say that, but I won't because with the built in Wizards, you could get away with knowing very little about these things, and still get great results. I would strongly recommend, however, adding the RTA-M reference mike to your purchase, unless you have something else equivalent. There are several Wizard programs, that will take you through setting up the DriveRack to recognize your system, set volume levels, auto EQ etc... Even pros should appreciate these apps as they pave the way to a great starting point in ringing out your system, and your venue. While Pink and White noise generation is available, the Wizards use frequency sweeps to tune the system, speaker by speaker, and point by point in the room. The feedback control is quite nice. With 12 filters that can be divided in to Fixed (for room characteristics) and Active ( to handle performance characteristics) this system keeps feedback on a very short leash. Getting the best out of your sound system is achievable as the Driverack has 6 XLR outs for stereo High, Mid, and Low speaker systems OR you can run a single chain for a simple mono system. The RTA Wizard takes your configuration and figures out where you should place the reference mike for it to analyze your system. The Automatic Feedback System (AFS) is used after you have set up a rough mix with all mikes in place. This clever little wizard listens to the system as you raise your mixer faders. You can hear the feedback begin, and then get squelched as the AFS kicks in. The fixed filters are set automatically, but you can change the Fixed/Auto filters allocation if you like/need to. Pros will appreciate the ability to control pretty much anything from the Display contrast, to the Crossover frequencies on each speaker array. The only thing i can think of to complain about is the size of the display, but even I think this is unfair because, let's face it, it is a 1U sized device. There is not a lot of real estate to work with. There is also a Laptop application that will allow access to the device via a router, with makes the controls much easier to manipulate. Whichever way you choose to control this device, you do not need to drill down through more than a couple of menu layers, due to the array of buttons that will bring you to each section's "Home" screen. In summary, you get a lot of bang for the buck. For most people, with simpler P/A systems, this is probably overkill, but wouldn't you rather overkill than underkill?

A must have !!! Buy it !!!
