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

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."

15IPS IS THE WAY!!!

I love the color that these add to my palette! I purchased a stereo pair of them and have been having a lot of fun using them on my drum bus. I love the effect it has on transients. Assembly was smooth and simple!Thanks DIYRE!

A Killer Hardware Plugin!

That’s what this is: an amazing 3D real-life plugin. You can push it to get gnarly saturation or tickle it for some light harmonic coloration. Easy to build. Amazing as a stereo hardware insert. Fantastic job, Peterson!

Great, however outstanding with less distortion mod

I use a pair of 15ips since 2 years and really liked the low end boost with mid enhancement. However beyond 60% lows became increasingly muddy and mids-enhancement sounded rather distorted.
I now did the 'less-distortion' mod and used 240 instead of 470 ohm for R6 (mk II) on another pair of ips15. Man the mod is insane! Now the sound appears more defined with more emphasis on the attack instead of decay concerning the low end. The sound now is more transparent and has more weight/body. The upper mids remain enhanced but hardly distorted. For me the R6/R7 mod lifts the module to another level. 240 ohm appears perfect in this respect.

Finally built mine and I love them

After having them for almost a year I finally got around to building my pair of mkii's.

All I can say is wow. This is probably my most favorite module. It does something very pleasing on everything you send through it.

I ran kick and snare through it, then the whole drum bus as a stereo send, then the master mix. It made a noticeable difference.

I am learning with the colour modules when to use it thick and rough and when to use just a pinch. There is a learning curve. Just a pinch of 15ips on each bus plus master bus is a good start.
