• •*can connect unbalanced signals from sources submixers, effects processors & keyboards to a main PA or Audio mixer. This impedance transformer also has buzz & hum cancellation ability.
• •*Aside from music instruments, the DI unit can also be connected to the line output of a boom box or consumer stereo system if you want to sample old records. The hum eliminator is used for connecting unbalanced devices as well.

Main highlights

Main highlights

• •Four totally independent DI box units in 1/2 RU package
• •Independent 20dB pad switch per channel
• •Independent ground (earth) lift switch per channel
• •Independent Volume control per channel for line mixer output
• •Independent pan control per channel for line mixer output

Main highlights

• •Passive Direct Box: This pair of DI boxes enables the connection of any unbalanced audio signal, for example an electric instrument or keyboard. It also works from an amp speaker output to any unbalanced input such as a mixer.
• •Attenuator Switch Box: The parallel output allows simultaneous connection to two separate inputs, like an amplifier and mixer. The attenuator switches from 0db, -20db and -40 db.
• •Direct Box: This direct box will translate high impedance instrument outputs into low impedance balanced signals. or balanced low impedance signals into unbalanced outputs.
• •Sound Attenuators: The attenuator switch makes correct output signal levels for optimum level matching to connected equipment possible. The switchable ground lift eliminates ground loop hum problems.
• •DI Box Uses: This DI Box will convert unbalanced +10db DJ mixer signals to a balanced line level signal, enabling interfacing with consoles more easily & longer cable runs. Great for clubs, churches, PA systems, monitor systems, karaoke or DJ systems.
