Palmer BRIDGE 4P - 19" DI box, 4 channels, passive
- Balancing and impedance matching for guitar, bass, keyboards & synthesizers
- Eliminates ground loop hum thanks to galvanic transformer isolation
- 4 independent DI boxes in a solid 19" housing (1U)
- Extremely fail-safe, no power supply required
- THRU-output for passing the input signal
- Audio over Cat output (AES72 Type 5e) for forwarding all signals via a single Cat cable
- Pure and unaltered low-noise audio
- Handles even high-level inputs without distortion thanks to switchable -30dB pad
- Ground-lift switch for each output
- Engineered in Germany
Are you aiming to capture the pure signal from a guitar, bass, or keyboard without any noise and tonal loss, even over long cable runs? In that case, you need a DI box - and a high-quality one at that - to ensure your sound won't be compromised.
The BRIDGE 4P from Palmer is a 4-channel passive DI box in 19" rack format with high-quality transformers that handle even high levels without distorting or losing the pure sound of your instrument. Each channel is equipped with a 1/4" jack input, a THRU output (for forwarding the input signals to an amplifier, for example), and two transformer-balanced XLR outputs - one at the front and one at the rear.
With a transformation ratio of 10:1, the transformers ensure optimum impedance and level matching for connecting instrument signals from guitar, bass, keyboard or synthesizer to a balanced microphone input. At the same time galvanic isolation prevents ground loop hum, so that the signal remains pure, clear and ultra-low noise, without any interference.
Thanks to a switchable 30dB pre-attenuation, the BRIDGE 4P can be fed with extremely high input levels in addition to line signals, which means it can even be looped in between the amplifier output and speakers, for example. The Audio-Over-Cat output enables the signals of all 4 channels to be routed via a single Cat (Cat5e or higher) cable. This saves material, space and time. Due to its passive design, the BRIDGE 4P requires no power supply, which makes it extremely fail-safe.
The BRIDGE 4P is the ideal solution for audio technicians, semi-professional and professional musicians as well as recording studios that value reliable and durable products.
