I upgraded to a Quad Cortex, so this box is officially fired.

If you are running an amp modeler, a massive stereo pedalboard, or keys, this is the gold standard. The custom-wound Sapphire transformers keep your low end tight and your highs crisp with a completely flat frequency response from 20Hz to 20kHz and incredibly low total harmonic distortion (THD).

Tech Specs & Features:

• D.I. / L.I. Switch: Select between Direct Injection (for high impedance sources greater than 1k like raw electric or bass guitars) and Line Isolator (for low impedance sources less than 1k like keys or amp/cab sims). In LI mode, your signal stays at full volume so you don't have to crank your preamp gain.
• Custom Sapphire Transformers: Premium, transformer-isolated outputs that seamlessly convert your unbalanced 1/4” inputs to balanced XLR outputs without coloring your sound.
• Sum XLR Switch: Got a tight channel count at the board? Engage this to sum the Left and Right signals into a single mono balanced output on the Left XLR jack (disabling the Right XLR out).
• Sum Thru Switch: Connects the left and right thru jacks together so you can combine your stereo signal into a single mono amplifier feed.
• XLR Phase Flip: Flips the phase of the Right XLR output relative to the Left to instantly fix cancellation issues in wide stereo setups.
• Utility Controls: Includes a GND Lift to isolate the XLR ground pin and kill hum, plus a -15dB Input Pad(functional only in D.I. mode) to keep hot signals from distorting.
• Passive & Foolproof: Zero power required. Since it's passive, you won't damage anything if you mix up your modes—if you lose your top end in LI mode, just click it over to DI mode.

Condition: Excellent. It was used exactly as intended, never abused, and functions perfectly. It’s built like an absolute tank and sits in a standard pedal-sized enclosure right on top of your board.
