A stage-rig essential, the Palmer BRIDGE 4P Passive DI Box harnesses a set of high-quality transformers that simply send the sound of guitars, basses and keyboards to the desk, noise-free and without any loss of tone. This four-channel unit comes wrapped in a solid 19 inch rack housing and has been designed to handle high signal levels without tipping over into distortion. Each channel has been kitted out with 6.35mm jack inputs, THRU inputs and two transformer-balanced XLR outputs, all to ensure optimal impedance and level matching. The Palmer BRIDGE 4P even features galvanic isolation to counter ground loop hum and guarantee a pure and clear signal. Versatile & Easy to Use This unit also keeps the set-up flexible thanks to a 30 decibel pre-attenuator switch, which enables the BRIDGE 4P to process extremely high input volumes and line signals, so this DI box can also be placed between an amplifier output and speakers. Using the Audio-Over-Cat output option, the signal of all four channels can be routed out via a single Cat5e (or higher) cable, saving space, time and materials while the passive design requires no external power supply, boosting the reliability of any professional stage and studio rig. Professional Performance Blending stage-proof build quality with high-grade components and consistent, reliable performance, the Palmer BRIDGE 4P has been designed to serve professional live engineers, recording engineers and musicians and do it for decades on end. Whether it's supporting live shows, studio recording sessions or rehearsals, this DI box guarantees pure, lossless sound, making it an essential sonic tool.
