Mackie Big Knob Passive 2x2 Studio Monitor Controller
A no-frills passive monitor controller at the beginner tier. It does one job transparently: a clean volume knob with switching for two input sources and two pairs of monitors, no power required. A fit for small studios that just need an honest volume pot and A/B speaker switching. Skip it if you need talkback, headphone outputs, or metering, since this is a switcher only.
