Alto Professional DI 4 overview

  • 1Description

The DI4 from Alto is a 4 channel, active direct box that covers several basic functions. It can convert a high impedance signal to low impedance, convert a "hot" instrument or line level (and sometimes even speaker level) signal to a microphone level signal suitable for connection to the microphone input of a mixing console, and prevent hum and noise pick up by the use of transformer decoupling.

Housed in a rugged metal enclosure, the direct box is mains powered and is equally suitable for use on stage or in a studio environment.

Professional, multi-functional DI box converts unbalanced input into balanced output for live and studio applications
Switchable dual input attenuators to achieve up to 40dB of attenuation
20dB gain switch for preamplification of low level signals
Accepts direct connection to up to 3,000W outputs for speakers
Phase and hi-cut (8kHz) switches per channel to further aid noise reduction
Special transformer decoupling helps to avoid hum and noise pick-up
Phase problems instantly corrected through phase inversion switch
Ground loop problems eliminated via ground lift switch
Accurate 8-segment LED level meter simplifies level setting for optimum performance
Gold plated XLR connectors and phone jacks for input and link output
