What You Need To Know
Like premium DI boxes costing 2-3X, Warm Audio active and passive DIs include all the features and rugged build expected to deliver a complete and professional audio experience.
The variable pad on the DI boxes is designed to help properly set levels from the DI to the mixer or audio interface. If distortion is audible, engage the pad and begin to apply attenuation until the signal is loud and clear.
The Phase switch reverses the polarity of the signal, correcting potentially poorly wired cables and eliminating phase-related noise issues.
The “instrument” setting on the switch works with all types of instruments using ¼” outputs. When using a signal from a guitar amplifier is desired, switch to “amp out” switch to send your amplified guitar signal to the DI and then out via the XLR output. **
Eliminate noise like hum and buzz caused by ground-loop issues. As more pieces of equipment connect to various power supplies, the chance of ground-loop hum issues increase.
**WARNING: Most guitar amps require a reactive load (a speaker) to be connected to the amplifier to prevent overheating. The best practice is to connect a ¼” cable to the ‘THRU’ input directly to a properly rated speaker cabinet. This ensures the amp is loaded properly, preventing serious damage to your amplifier.
ACTIVE ONLY - ACTIVE/PASSIVE SWITCH: The active version of the DI has LED indicators to show if 48v is being passed from the connected device - such as mixers, interfaces, or stage boxes. The active/passive switch changes the operational mode of the DI from active (power engaged) or passive, using no 48v power.
