Electrical Audio DI
Electrical Audio Direct Box
The Electrical Audio Direct Box is an exceptionally versatile tool designed for traditional DI applications as well as general bi-directional impedance conversion tasks. Transformer-based and fitted with both male and female XLR connectors, it can interface with virtually anything in a studio for a wide range of practical uses.
Direct Injection (High-Z to Low-Z)
In standard DI operation, the Electrical Audio Direct Box converts high-impedance instrument and line-level sources—such as guitar, bass, effects pedals, keyboards, and phone or computer audio—into a low-impedance, balanced signal. This balanced output can be sent over long cable runs without degradation when connected to a typical microphone preamp.
Reverse Operation (Low-Z to High-Z)
The Direct Box also operates in reverse, converting low-impedance signals to high impedance. This is essential when sending a microphone signal into a guitar effects chain or amplifier. In this configuration, the original unconverted microphone signal remains available via the male XLR connector.
This design uniquely allows the use of phantom-powered microphones for re-amplification and processing. The Direct Box is also ideal for re-amping applications, converting recorded line-level signals back to instrument level for routing into guitar amplifiers or pedals.
Key Applications
- Direct injection of instruments and line-level sources
- Long-distance balanced signal transmission
- Sending microphones into guitar pedals or amplifiers
- Re-amping recorded tracks through guitar amps or effects
- General-purpose bi-directional impedance conversion
