The ZDA4.6 is an extremely versatile Digital Signal Processor (DSP) with a built-in 4-Channel amplifier. The 6-channel DSP gives you all the features needed to create your perfect audio setup, such as fully adjustable filters, EQ with adjustable Q value and time correction.

This feature packed amp does not end there though, a built-in 4x60W RMS amplifier runs off channels 1-4 on the DSP so you have full control. If you want even more power, you can even use the 6 channel RCA outputs that are also controlled by the DSP.

The ZDA4.6 will run on any source, connect the high-level input and this will be your source, or you can use the RCA input. You can even add a BT module to the amp and get high-quality streaming and full APP control through your iOS or Android device.

Also available is a remote-control unit that gives you volume and bass control, along with memory recall. The remote will also give you a USB input in the front which makes it easier to connect to a PC and allows you to do the tweaking in the front of the vehicle.

But it doesn’t stop there, with the ISO-T harness that is available as an accessory, the ZDA4.6 becomes the perfect integration amp. It will take a high-level input from the car, pass it through the DSP and send it out from the internal amplifier to the speakers in the car, giving you the power and control you need.

If the power isn’t enough simply add a second normal amplifier and you have the full functionality of the DSP to make the additional amp work as a SUB amp for even more power to your high power speakers.
