The reason i say ULTIMATE, and use caps, is because this product isn't just pretty lights. Once calibrated with your DD-1 (or scope), you can see in real time when you are pushing the system just a little too hard. Set it to get red about the time your DD-1 shows red and you will know when you are reaching your limits, and can back off, possibly saving a speaker's life Sure there are other pretty lights out there, but this one actually has substance, to go with the style. Anyhow, you will notice, the new ones have a new "peak hold" feature. Tony showed me it and i LOVED it so much, i demanded they all be that way. We were considering making an OM-1p and actually having 2 products, but i want this to be on all of them. If anyone here has purchased the original model, and would like "peak hold" on your unit, unfortunately, it will need to be sent in to be reflashed. It costs about $5 bucks each to pay someone to sit down, tear it apart, reprogram it, put it back together and then test it. I tell you what though, send yours to me and i will cover the $5 upgrade and ship your's back to you. I also ate the costs to have all the new units done and will not raise the price. All new units will come stock with the peak hold but if you do NOT like it, please let me know! i have some that aren't reflashed yet. anyhow, watch the vid! check out a low/mid/high setup i did this morning.
