Are you looking to pick up a pure guitar, bass, or electric piano signal with all its brilliance and without any tonal alterations? An active DI box offers the best solution - as long as it has the same high-quality construction as the Palmer havel. The havel's low-noise active circuitry allows a higher input impedance than a passive DI box. This means the sound of the instrument is captured without treble or bass losses. High-level input impedance is especially important in interaction with the magnetic pickups in electrical guitars, electric basses and electromechanical electric pianos (e.g. Rhodes), as well as with (passive) piezo pickups for acoustic instruments. However, the Palmer havel is also very well suited to synthesisers and other electronic keyboards, since it offers enough headroom to handle even high-level inputs without unwanted distortion.  

Of course, the Palmer havel features a THRU output to pass the input signal on to the instrument amplifier. With 30 dB of pre-attenuation activated, the Palmer havel can also be looped in between the amplifier output and the loudspeaker, if you want to include the sound of the amplifier instead of the “raw” instrument signal. 

The balanced, low-impedance output signal from the Palmer havel is resistant to interference, which enables long cable runs without any loss of sound quality. Thanks to the built-in transformer, the XLR output is galvanically isolated. Any hum loops that may occur can easily be remedied by pressing the ground lift switch. For a power supply, a 48V phantom power unit or a standard 9V battery can be used. 

We're sure you’ve spent a long time searching for YOUR sound, and have invested a lot of time and money to get your instrument to sound the way it should. The Palmer havel transmits your sound faithfully and free of interference. This means your sound reaches the listener exactly as nature intended!

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.
