Palmer BRIDGE 4P Passive 4-Channels DI Box - 19"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

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.

Features

  • 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)

  • Handles even high-level inputs without distortion thanks to switchable -30dB pad
  • Ground-lift switch for each output
  • Engineered in Germany

Excellent fit and value - recommended buy
Size: 3+12+12+2+1 pack
I rarely write reviews, but I'm so impressed by the fit and quality of this set that I made an exception. I'd been running my eufy 11S without brushes, and have been cleaning and reusing the filters for a while now and finally decided to buy replacements. The kit came packed well with everything in order and no damage. I replaced all of the worn parts and installed the brushes and did a test run - everything worked great. I expected some fitment issues because I've seen that with other kits, but I had no issues. The fact that you get multiples of almost everything is icing on the cake. Oh, and I wasn't paid or given anything in exchange for this review, as much as that's worth now, haha. I can recommend getting this kit for your robot vacuum, if it's the right set for your model.

Good option for an aftermarket replacement solution.
Size: 3+12+12+2+1 pack
I've been very happy with this product. I think it is a good price point for what is included. Everything was a directly compatible and everything fit as you would expect. The filter quality is good and since there are plenty in the kit I find I change the filters more often which is probably a good thing. I recommed.

Eufy Brushes wear out with daily use
Size: 4 Pack
These brushes help the Eufy continue to run efficiently. I have 2 dogs and run 2 Eufies daily. It is surprising how much sand, dust, gravel and hair gets vacuumed. My furniture isn't as dusty and my floor doesn't need mopping as often.

Fits my old eufy
Size: 3+12+12+2+1 pack
This set fits my older model eufy and has extra parts for newer models. The filters did not fit our model (our fault for not doing proper research) but the fan sweeper is awesome.
