Their ZRS-C7 is the same board as the american bass 500.1
Their newest, biggest 4 channel is the ZRS-C9( I have 2 of them, serial numbers 17 & 18) and its the same case, and VERY similar boards to the AQ 4 channel.
Cadence is sponsoring me for next year, so if you have any questions, feel free to shoot me a PM.
