Palmer PBRIDGE4P 19" Rack Mount 4-Channel Active DI Box

Professional musicians and audio engineers know that maintaining signal integrity from instrument to mixing desk can make or break a performance. The Palmer BRIDGE 4A is a premium 4-channel active DI box housed in a robust 19" rack format, specifically designed to convert the unbalanced, high-impedance signals from electric guitars, basses, keyboards and synthesisers into transformer-balanced, low-impedance outputs suitable for mixing console microphone inputs. This active circuitry maintains an unaffected frequency response while achieving superior dynamic range and higher output levels compared to passive alternatives.

Each of the four independent channels features a 6.3mm jack input, THRU-output for signal forwarding to amplifiers, and dual transformer-balanced XLR outputs positioned at both front and rear panels for maximum connectivity flexibility. The inclusion of switchable 30dB pre-attenuation allows the unit to handle extremely high input levels, making it suitable for line signals and even amplifier output applications. Ground-lift switches on each output eliminate mains hum and interference caused by ground loops, ensuring your audio remains clean and interference-free.

A standout feature is the Audio-Over-Cat output capability, which routes all four channels through a single Cat5e cable or higher, significantly reducing cable requirements and installation complexity. This German-engineered solution operates on 9V DC power and represents the ideal choice for audio technicians, semi-professional and professional musicians, plus recording studios that demand reliable, durable equipment for critical audio applications.
