Kurzweil Mangler

Kurzweil Mangler Multi-Effects Processor

Kurzweil Mangler is based on the effects found in the KSP8, Kurzweil's flagship multichannel effects processor, and offer easy-to-use effect presets for any environment. Both models are single rack space units featuring 192 effects presets, 64 locations for user-created presets, balanced stereo analog inputs and outputs, S/PDIF digital I/O, and pre-effect EQ.


The Kurzweil Mangler focuses on effects other than, but not excluding, reverb. These include chorus, flanger, phaser, tremolo, rotary speaker, panner, delay, filters, LaserVerb, Pitcher , synth trigger, ring modulation, distortion, and compression effects, and many combinations.

You can access all of the effects in your Kurzweil Mangler using the BANK and PRESET knobs on the front panel. Turn the BANK knob to select the general type of effect. Then turn the PRESET knob to display the 16 different effects in the current bank. Appendix A provides a list of the effects included with each unit.

When you start customizing effects in the Kurzweil Mangler, you’ll be able to store them in the banks labeled User 1 through User 4. Like the other banks, each of the User banks can store 16 different effects.

The power supply is a standard 9V AC 2-amp external supply. There is no power switch; your Kurzweil Mangler will be ready to use as soon as you plug it in. You can attach both analog and digital input cables to the unit, although you can use only one type of input at a time. Set the Input Source parameter on the Master menu to tell the unit which inputs it should use.

Also, you may want to check the setting of the Wet/Dry Mode parameter, depending on whether you’ve connected the unit to your mixer as a direct insert or as a send/ return (bus) effect. Analog and Digital outputs are always available, so that you can use both at the same time.

Stereo analog inputs and outputs are balanced 1/4” jacks that will accept either balanced TRS (tip-ring-sleeve) or unbalanced TS (tip-sleeve) connectors. When you plug a single cable (i.e., a mono signal) into either analog input, the unit sends that signal to both input channels (provided that Input Source is set to Analog, of course). Set the analog input level using the knob on the front panel of the unit.

I’ve had this since it was new. This is a very deep machine and in all these years I feel I am only still scratching the surface. I probably won’t exhaust its possibilities in my lifetime. I took points off for not having a power switch and for the line lump PSU. Beyond that it’s hard to find fault. To my ears it sounds awesome and has incredibly nice conversion. Sometimes I run other effects into it digitally just to use its converters. The algorithms are a mixed bag. Some sound as generic as your average VST effects but others are absolutely outstanding. With tweaking there’s much more than meets the eye. Even the tame sounding algorithms have extended parameters which can be used to wake them up and make them shine. The more extreme algorithms are cool AF. The unusual reverbs and delays can trip you out for endless hours. The overdrives and distortions are full and organic. The Quantize + Alias can be very carefully adjusted to emulate the different sounds of vintage samplers really closely. The frequency shifter and ringmod are the best examples I’ve ever heard. The compression algorithms are surprisingly good! I would use them on a mix bus without hesitation. When you dig deep into the extended parameters you inevitably find gold. Just make sure you have enough time because it’s like a bottomless pit. If they ever reissue this machine take my money, please.
