Big Knob Studio+ with RDI5 DI Box and PRO-M50 Headphones

Build a project-studio monitoring and recording setup around the Big Knob Studio+ 2 x 4 USB interface, with an RDI5 DI box, PRO-M50 closed-back headphones, and a 10-foot XLR-to-1/4-inch cable in one bundle. The controller switches among four sources and three monitor pairs, with independent trim plus mono, mute, and dim controls for quick listening checks. Its 192 kHz / 24-bit recording and playback, two mic preamps with phantom power, and cue mix support vocal takes, guitar and keyboard recording, and podcast sessions. The RDI5 converts guitar, line-level, or speaker feeds to balanced XLR and includes switchable attenuation and ground lift. For monitoring, the headphones use 40 mm neodymium drivers, swivel ear cups, and interchangeable leather or suede cushions. The 10-foot, 100% copper cable links compatible gear, and the included headphone cable, case, adapter, ear pad, and DI box give a small studio a practical starting kit without sourcing these pieces separately.
