ZAPCO DSP-Z8IVII 4+

The Zapco DSP-Z8IV II App allow you to setup and tune your system with your smartphone. The goal here was to have a control system that made sense in a smaller platform but would allow the user to do everything necessary for a complete setup and tune.
When you open the App your smart device will sync to the settings that are in the active preset in your DSP, so you will always open the App to the settings you are listening to. From the Channel Page, you can assign the function of each speaker, choose which input channel the speaker will have, check the Phase for polarity, and adjust the individual channel gains. When you set the speaker functions in the Channels Page the system will assign default crossovers to protect your valuable speakers from frequencies that can be dangerous to them. You can customize the crossovers to fit the needs of your individual system. The Delay Page lets you enter centimeters or inches and immediately give you the applicable Delay in milliseconds for a rock solid and accurate front stage.
The EQ Page holds the heart and the brains of the App. You can use either the Graphic or the Paragraphic EQ’s. The EQ bands slide to reveal all 31 bands. You have adjustments for gain, frequency, and Q factor. You can work on channels individually or you can link them into pairs with the link icons. At the top of the page you can save a setup-and-tune to the DSP, and you can also save it to a file on your smartphone. You can also choose to load a preset from the DSP or from a file on your smartphone. The graph shows how your adjustment are affecting the signal going to the amp and you can choose to have just the active channel show on the graph or have more show, with the drop-down menu.
