Plug your stereo high-impedance gear into your low-impedance rig with the dbx DJDI 2-Channel Passive Direct Box. Requiring no power supply, the DJDI can conveniently operate in situations where phantom power is not available without needing battery changes to power active electronics found in some DI boxes. A built-in ground-lift switch can help avoid noise from ground loops. Another feature on the DJDI is the input attenuator which prevents overloading from high-level signals.
