ART PDB4 Four Channel Passive Direct Box

Enhance Your Audio Setup with ART PDB4
Introducing the ART PDB4, a state-of-the-art four-channel passive direct box designed to integrate seamlessly into any professional audio setup. Housed in a sturdy 1U 19-inch rack mount chassis, the PDB4 combines functionality and durability, providing four high-quality transformer isolated direct boxes in one compact unit. This is the perfect solution for musicians, sound engineers, and producers seeking to connect electronic musical instruments or audio sources to balanced inputs with impeccable clarity and isolation.

Maximum Isolation for Pristine Sound
Each of the PDB4's four channels is meticulously designed to ensure maximum isolation, enhancing channel separation and preserving the integrity of your sound. Transformer isolation on each output significantly reduces system ground loops, a common issue that can degrade audio quality. With the PDB4, you can expect nothing less than a clean, transparent signal in your recordings and live performances.

Versatile Connectivity Options
The PDB4 is not just about quality sound; it's also about flexibility. Whether connecting outputs from synthesizers, drum machines, or any audio source to a mixer, the PDB4 ensures a seamless interface. It even allows you to connect a music source directly to an instrument amplifier while routing it to a mixer, making it an invaluable tool for both studio and stage setups.

Tailored to Your Needs
With switchable input attenuation (0dB, -20dB, -40dB), the PDB4 adapts to various signal levels, ensuring optimal performance across a wide range of instruments and equipment. The 50k ohm instrument/line input and parallel link jack, along with a 600 ohm XLR output jack, offer extensive connectivity options, catering to the diverse requirements of modern audio production.

Ground Lift for Noise-Free Operation
The inclusion of a switchable ground lift on each channel further elevates the PDB4's capability to deliver noise-free audio. This feature is essential for eliminating hum and buzz caused by ground loops, ensuring your sound is as clean and clear as possible.
