Mackie is now delivering the ProDX4 and ProDX8 digital mixers — two new models that are not only extraordinarily low in cost, but so easy to use that virtually anyone can operate one in less than an hour.

The new line features the four-channel ProDX4 and the eight-channel ProDX8 models. Each has wireless streaming and control, powerful processing and a control app for iOS and Android devices. These mixers are also small and light — weighing only 2.2 pounds for the four-channel model and 3.2 pounds for the eight-channel model.

The mixers are controlled by portable smart phones when connected via Bluetooth. They feature a single knob design for easy control and use a free MixerConnect app to unlock recallable mix presets, to control built-in processing like EQ and compression per channel and to use 16 ReadyFX digital effects.

Both mixers use Mackie's Wide-Z mic preamps and have combo inputs that allow connection of mic, line and instruments. They require no gain adjustment. Each channel has three-band EQ and compression. The outputs feature a graphic EQ.

Other than a couple of obvious omissions, these mixers are fully professional and could serve in a wide range of applications for professionals. What’s missing, however, could be a deal breaker for some.

First, there is no phantom power for microphones. Either use dynamic mics or self-powered condensers. That’s a severe limitation. And second, there is no digital output for recording. To record with these mixers, you have to feed your recorder an analog signal. Again, a major design oversight.

Mackie made these mixers usable by anyone, but shortchanged the feature set. It is an error that will hurt their sales.

If these mixers work for your application, they can be had for a very low cost. Street prices for ProDX4 is $199.99 and the ProDX8 is $299.99.
