Sound mixers can be daunting devices. With a wide range of knobs and dials, they accomplish audio miracles. Sometimes, though, you just need a simple solution that can achieve similar results. Rakimix bills itself as a “simple but proficient mixer” which includes 4 controllable channels and one auxiliary channel.
The device can be daisy-chained with another Rakimix or any other mono audio source to create larger channel count mixers. The channels have a level control that ranges from off to +10dB gain. Mute switches allow you to keep level settings and mute the sound on individual channels.
The master volume adjustment works across the four main channels but does not affect the auxiliary input. The auxiliary input is usable with any mono audio signal up to 4Vpp. The output signal is a mix of the 5 channels transmitted to the tip and ring of a stereo output. You can use a mono or stereo cable on the output.
To power the device, you will need a 9V PP3 battery to use with the battery-barrel jack connector included in the kit. If you prefer a power supply, it should be rated +8V to +12V DC and have a center positive barrel jack.
The Rakimix kit comes with a user-friendly assembly guide that you can also view online with pictures, hints, and tips. It’s classified as an intermediate DIY kit that requires a soldering iron and a pair of flush cutters. Beginners shouldn’t be afraid to give this a shot, however, as the kit comes with a cheat sheet to identify the resistors based on their color bands.
