BOSS DI-1 Direct Box

【Product Name】
BOSS Direct Box DI-1

Thank you for your interest in the BOSS DI-1.
The DI-1 is a professional piece of equipment used to convert the unbalanced signal from instruments like guitars, basses, and keyboards into a balanced signal that mixers and recorders can accept. It ensures clear, low-noise signal transmission in all situations, including studio recording, live performances, and home recording.

【Features and Characteristics】
* High Sound Quality with Active Circuitry: The DI-1 employs an active circuit, minimizing signal degradation and faithfully transmitting the instrument's original sound.
* Versatile Input Compatibility (ATT Switch):
Equipped with a 3-stage attenuator (ATT) switch. This allows for optimal settings according to the input level, from low-level signals of electric guitars and keyboards to high-level signals from amplifier speaker outputs.
* Ground Lift Function (GROUND LIFT): Features a ground lift switch to cut hum noise from mixers and other equipment, as well as noise caused by ground loops, making it effective for noise reduction.
* Phase Switching Function (PHASE): Includes a phase switch to correct phase shifts that may occur between connected equipment. This is particularly useful when using a microphone and DI simultaneously.
* Two Power Supply Options: Supports power from a 9V battery as well as phantom power (PHANTOM DC) from the mixer. This offers excellent usability for live and studio settings. Additionally, the AUTO POWER function turns the unit on only when a plug is inserted into the input jack, preventing battery drain.

【Product Condition】
As you can see in the images, there are marks from tape removal on the unit. Regarding its functionality, upon checking for this listing, all functions such as input/output, ATT, ground lift, and phase switching are operating normally, and it is ready for immediate use.

We confidently recommend the BOSS DI-1 to anyone looking to improve their live or recording sound quality, or seeking a reliable active DI, due to its dependability and high sound quality.
