AIYIMA 4 x 6 Channel Mixer Box

Like everyone , my system is growing and I needed more capacity. The mixer box is made of 4 - AIYIMA 6 Ways Stereo Mixer boards. The output channel of each mixer can be jumpered to the input of another to daisy chain the boards. This allows up to 21 stereo devices to be connect at once. Paper printed labels can be slid into the slots to identify the channels. The mixer does amplification and I found it to be better/cheaper than the 4 channel the Volca Mix.

I printed mine on PLA plastic, face down with supports -touching the build plate option . I like to print on painter's tape and glue stick on top of the tape to insure the print will stick to the bed.
