The compression, saturation, and tone of analog tape. (Everything but the hiss.)

For decades analog tape was the sound of records. Then the technology changed, but our ears didn't. Things tracked on tape just sound fuller, warmer, and more "finished" by default than things tracked digitally. Bring the sound of tape back to your recordings with the 15IPS Colour.

The sound of tape comes from three things—compression, harmonic saturation, and filtering—and the 15IPS does all three.

Compression

Tape has a "built-in" compressor; that is, it can only take so much signal and anything above that limit is compressed. The 15IPS' ladder of diodes recreates this soft clipping, making sounds fuller and more present in the mix without adding more volume.

Saturation

The "warmth" of tape comes from the harmonic saturation of both the tape itself and the electronics of the tape machine. The 15IPS' diodes emulate the harmonics generated by the tape, while the discrete transistor circuitry creates the complex harmonics of a vintage tape machine.

Tone Filtering

Part of tape's distinctive sound is its non-linear frequency response: a low-end roll off with a "bump" at the cutoff frequency. The 15IPS features a 40Hz resonant high-pass filter that simultaneously makes the low-end tighter and larger-than-life.

FEATURES

  • Tape-like soft limiting with NOS germanium diodes
  • Multiple class-A transistor stages for richer, more complex harmonic saturation
  • Resonant high-pass filter simultaneously clarifies and magnifies low end
  • Compatible with the Colour format
  • Yellow PCB
  • Full, step-by-step assembly instructions and support

Note on Revisions

The 15IPS is currently on its third revision. The 15IPS mkI, (2014-2019), featured an IC opamp and a relatively high clipping resistor for more saturation. The mkII (2019-2023) replaced the IC with a discrete, class-A transistor circuit and reduced the clipping resistor to widen the sweet spot of the Colour. The current version, mkIII, is identical to the mkII but with schottky diodes instead of germanium. An additional resistor in the clipping circuit replicates the character of the original diodes exactly. However, because the gain staging is slightly different between each one, two 15IPS from different revisions will not make a stereo pair.

What the Pros are Saying

"Even a little bit of the 15IPS adds a warm vibe and a huge low end. Just switching it in can thicken up a kick drum, bass or even a whole mix. With more drive, 15IPS gives a great saturated tape-like squash."

Best air flow
Size: 9.6" x 11.1" x 2.2"
I have a 2022 ram 1500 four-door. The factory filter from the ram dealer is about $40 but it’s not reusable. That was the only one I found that had good airflow into the cabin. I tried several other brands but the airflow was reduced excessively. The ram filter was 15 mph, most of the other aftermarkets dropped the airflow to about 9 mph. I just installed a K&N reusable filter and the airflow is back up to 15 mph. Great job K&N!!

Fits Well and Reusable. I'm Happy.

For less than the price of 2 disposable FRAM CV11671 cabin filters for my 2019 RAM 1500 and this will last forever. If it gets wet, like I've had happen with the paper throw-away filters due to stuff falling off trees in the spring and clogging cowl area water drains and backing up into filter ( yeah, that's a thing ) and can clean and dry this filter and reuse. Great directions came in the box along with a sticker to point out that this is a lifetime filter so someone doesn't throw it away. Do this yourself. Don't let some auto repair shop talk you into it. I was getting tires balanced recently and heard a quote they gave over the phone of $79 to do this. I don't know what kind of vehicle that was for but this ain't rocket science. Don't get ripped off. Now back to this filter. There is no arrow for air flow so I figure it flows well both ways and just put it in with the K and N logo right side up and facing out. It's not a straight in shot the way RAM positioned the opening for the cabin filter slot but was no big deal. Also realize this isn't a perfect square filter ...It's a rectangle so don't try to shove the fat end in and say it doesn't fit. I haven't noticed any air flow differences with the heating / ac system but some people say they do. I'm just happy I don't have to buy anymore disposable filters and can dry this if it gets wet. The cleaning and refresh spray kit is #99-6000 that comes with a 8oz and 12oz bottle and I'm trying to find that cheaper somewhere for when I do clean this thing.

Can’t go wrong with K&N
Size: 9.6" x 11.1" x 2.2"
So I recently took my pickup in to have some recall work done, half way through the process I got a call from the dealership stating I needed a new air filter and that a new one would cost nearly $60. I chuckled and told then to put the old one back in and I immediately came to Amazon and ordered this cabin filter. I’ve used K&N products in the past and have never been sorry, and that is the case with this lifetime filter. Upon installing this filter I noticed an IMMEDIATE difference in air flow into the cabin, it even smelled better. If this filter ever gets dirty Ira easy to clean and reinstall, paying for itself over time. Do yourself a favor and pick one of these up, you will not be sorry.

Easy replacement and noticeably fresher air
Size: 1-Pack
Installation was quick and simple, and it fit perfectly in my vehicle. I noticed an immediate improvement in the air quality inside the car. The activated carbon helps reduce odors and keeps the air feeling cleaner and fresher, especially during everyday driving. The filter feels well-made and durable, and it does a great job trapping dust and debris. It’s a simple upgrade that makes the driving experience much more comfortable. Overall, this is a great quality cabin air filter that delivers reliable performance and excellent value. Definitely recommend!
