Greetings gents (and potential ladies), so if anyone has overshadowed my other thread, I am looking to upgrade to all Zapco DC-series amps. (2 x 360.4 and 1 x 500.1) I kept running across a zapco DC501, not a 500.1, and was confused as why the appearingly same amp was being mistaken for multiple times. specs appear to be the same, however turns out a side by side picture of the each inputs and whatnot they are indeed different. is the DC501 a new model of the 500.1? What are the differences?
Zapco DC501 is the current version. It runs on the newer Zapco DPN software where it has a couple new features. One being a eq that can be triggered by monitoring voltage for when you want to boost or lower certain frequencies at certain volume levels. The other big difference is the inputs. The new 501 accepts unbalanced RCA inputs compared to the original that only accepted balanced DIN input.
