ART PDB4 Four-Channel Passive Rackmount DI Box
The ART PDB4 is the ultimate tool for musicians and audio professionals who need dependable, clear, and balanced signal routing from multiple unbalanced sources. Its four independent channels allow you to connect instruments, line-level devices, or speaker signals to balanced inputs with ease — all without requiring any power.
Balanced Signal Clarity
Firstly, each input on the PDB4 sends your signal to a transformer-isolated balanced XLR output. Thus, minimising hum and noise. This guarantees your sound stays pure and professional whether you’re in the studio or live on stage. Also, each channel offers a switchable ground lift to remove any pesky hum that can spoil a flawless performance.
Versatile Signal Handling
Moreover, with switchable attenuation levels of 0 dB, -20 dB, and -40 dB per channel, the PDB4 can easily manage high signal levels without distortion. The parallel thru jacks let you connect directly to an amplifier. Therefore, making it perfect for live setups where monitoring and sending signals simultaneously is essential.
Passive Convenience and Rackmount Design
Since the PDB4 is fully passive, it operates without any external power source, eliminating the need for batteries or power supplies. This makes it perfectly suited for use with powered gear like synthesizers or active pickups on guitars and basses. Its 1U rackmount enclosure fits neatly into your existing rack system, maintaining a clean and organized setup.
Enhance your audio system today with the ART PDB4 — the reliable, powerful passive DI that delivers exceptional sound quality and convenience.
