Wohler AMP1-2SDA+ Reviews

There's a reason why Wohlers are in every edit suite, control room, or QC bay I've ever worked in-- they're brilliant, and they're bullet-proof.� This model is no exception. I was really bummed that they discontinued their last multi-channel analog monitor just before I tried to buy it, but this is a game replacement with the added benefit of AES/EBU and SDI (which I'll probably never use, but at least it's there). Everything just feels right on the unit-- the knobs are all chunky and solid-feeling, and the control is intuitive.� And, of course, the sound is classic Wohler "ultra-near field"-- more than loud enough, and the imaging makes it feels like you're wearing headphones when you're not. Please note, you will need DB25 breakout snakes for the analog inputs-- they're listed as a related item in this item's listing.� They are simple to connect and space-saving!
