Doepfer A-138j Inverting/Interrupting Mixer (Janus Mixer)The Doepfer A 138j is a 6HP, four channel mixer with an additional polarity mute switch for each input. In the upper position of the corresponding switch the inverted signal is used. In the center position the input in question is turned off (mute) and in the lower position the "normal" (i. e. non inverted) signal is used. The inverting of signals is used especially for control voltage signals (e. g. LFO, ADSR). But even for correlated audio signals

Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

Balls
Size: Medium
My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.

Nice set of balls
Size: Medium
The squeaker quickly became my dog’s favorite ball and has replaced the fuzzy tennis balls. My dog is a nonstop fetcher and these chuck it balls are durable and fun.
