Radial SAT-2 stereo attenuator and monitor controller, from my own rig. Excellent condition and fully working — no issues, no surprises, no original box.

This is the unit you put between your interface and a pair of powered monitors (or any speakers) when you want a real volume knob within arm's reach. Fully passive, so there's nothing to plug in for power and nothing to fail. It's also a variable pad: run it between hot mic preamps and your converters so you can push the preamps into their sweet spot without clipping the inputs on the way in.

What it does:

• Passive design, no power supply required
• Master level control on a 4-pole rotary knob for consistent left-right tracking across the full range
• Dim switch with its own recessed level control, so you can drop the volume temporarily without losing your main setting
• Mono switch for checking mixes for phase coherency
• Mute switch
• XLR and 1/4" TRS inputs, XLR outputs
• Works with balanced or unbalanced line-level signals
• 14-gauge steel enclosure with a no-slip pad underneath for grip and isolation

Condition: Excellent. Everything works as it should — the level pot is smooth and tracks evenly, and the dim, mono, and mute switches all function with no issue. Any minor handling marks are shown in the photos. These are built like a brick and this one has been treated well.

I'm a working musician and engineer selling gear from my own rig. I grade conservatively, describe honestly, and pack carefully. Will always try to ship same day.
