Mackie Big Knob Passive Studio Monitor Controller

Used like new. I bought it used recently but it works perfectly. I'm selling it as I found a more suitable product for my audio setup.

Here's the specs:

For up to two monitor pairs and three stereo sources

Passive +4 dB signal path without separate power supply unit

Large volume control

Switch for mute, dim, mono, monitor and signal source

3 Stereo line inputs: 2x 6.3 mm jack balanced, 1x 3.5 mm jack unbalanced

2 Stereo monitor outputs: 6.3 mm jack balanced

Steel casing
