## Description

Product description

Review: They just work - We use these at our small church and they work just fine. The best feature is actually that the ground/lift switch is slightly inside the housing. This prevents accidentally switching it. We use them for both acoustic guitars and electric piano and have had no issues in 2 years with them.
Review: Inexpensive but rock solid performance - The direct boxes I received are basic, no frills units- they all work just fine- good sound transfer, no unwanted noise. They are solidly built and look and feel very roadworthy. A good value at this price point.

## Features

- 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.
