Introduction A direct insertion box, or DI box, converts unbalanced high impedance signals to balanced low impedance signals. This provides the facility to run long cables without deterioration of the signal, as well as connecting audio signals to a mixer’s microphone input. Samson’s S-Max Direct Boxes combines premium sound circuitry with durable, roadworthy construction to provide high-quality signal connection solutions for live and studio applications.
Callouts 1 2 3 4 1. INPUT – 1/4” hi-Z input jack for connecting for instruments or line level signals. 2. THRU – 1/4” output for passing the input signal through to a stage amplifier or monitor system. 3. GROUND LIFT – When the switch is engaged, the input ground (shield) is disconnected. 4. BALANCED OUTPUT – Male XLR low-Z connector.
Setup The MD1 can be quite useful on stage or in the studio for connecting unbalanced audio sources or instruments with pickups. By utilizing the MD1, the signal can be sent cleanly for long distances while benefiting from the low noise and common mode rejection provided by the balanced low-level output. The diagram following shows a typical hook-up for an acoustic guitar connected to an acoustic guitar amplifier and a PA system.
