a smooth flat overall transition), and although these will often be precisely specified by speaker manufacturers, they can be freely adjusted if desired. The DriveRack® PA2 provides all the processing you need between your mixer and amplifiers to optimize and protect your loudspeakers. When setting up special setups you will need to think which wizard choices enable what you need and then set up the crossover manually. it's post‑crossover), so it's possible to apply different settings to each band as dictated by the power amps and speakers.

I did try to trick it into assigning a filter on a keyboard note, but the algorithm worked as it should and my sustained note wasn't removed! A buddy of mine also bought one of these units and warned me about the fact that you have to unmute the outputs after doing the feedback ring out. I connected the AFS2 into our rehearsal studio PA and went through the setup wizard with four open mics to see both how effective the feedback reduction was, and what effect it had on the overall sound.The PA2 incorporates an automatic feedback suppressor (AFS), which can detect the onset of audio feedback at any particular frequency and then quickly apply a very sharp notch filter to attenuate it.

The DriveRack® PA2 provides all the processing you need between your mixer and amplifiers to optimize and protect your loudspeakers. Now, these may add up in different ways, but ultimately, if you put in the output of a DAC that's fairly clean, say 120dB SINAD, you'll likely get, at best, a 94dB SINAD out of PA2. The data wheel acts as an 'enter' or 'confirm' button, and all the text is easy to read even when it's highlighted. The dbx DriveRack® PA2 ended up being my choice with the matching RTA microphone as the cheaper option had (luckily!Applying post‑crossover limiting has the advantage that, as the different frequency bands are unlikely to reach the limiter threshold at the same time, part of the output signal will remain uncompressed by the limiter meaning that the sound won't all be squashed flat just because one band has reached the limiter threshold, so the gain reduction applied will tend to sound more natural and retain some of the programme dynamics.

Reliability - again, based on all the reviews, this unit will perform a long time, especially if you take good care of it and don't block its heat vents.In simple terms, the DriveRack PA2 is something that sits between your mixer outputs and your power amp (or powered speaker) inputs, and it acts as a comprehensive speaker‑management system.

Although the functions within the PA2 can be used and controlled individually, one of the benefits of having an integrated one‑unit solution is that they can be set up together, and the PA2 incorporates a fully automatic Setup Wizard that guides the user through the whole process, and is designed to apply the processing needed to optimise a live‑sound setup quickly and easily, and without requiring any specialist knowledge of the functions involved. As a user of the previous model myself I was interested to have a look at its replacement in the product line.

It "listens" to your room via RTA mic (not included), analyzes it, and sets the appropriate speaker levels and room EQ. Wizard functions on the DriveRack PA2 guide you through easy, step-by-step processes to help you get the most from your loudspeaker system.
