Impulse Response Technology in Strymon Iridium

Impulse responses allow the sound and character of a mic’d speaker cabinet to be captured, so that any audio signal can be processed by the resulting impulse response and sound as if it’s being played through that exact speaker cabinet. Iridium is able to deliver impulse response resolution far greater than any other piece of outboard gear.

With full 24bit 96kHz resolution for the entire 500 milliseconds of its speaker cabinet impulse responses, Iridium is able to use the absolute highest quality IRs available. This means countless details are accurately preserved and reproduced to give you a completely real speaker response. Every cabinet resonance, speaker vibration, as well as reflections between the cabinet, the mic, the floor, and the ceiling; all the minuscule cues that tell our brain we are listening to our favorite cabinet are preserved, providing completely lifelike realism.

Load Own Impulses into Strymon Iridium

It’s easy to replace the pre-installed IRs with custom IRs from your own collection by using Strymon Impulse Manager software. To download the software or learn more, visit strymon.net/support/iridium. 

Where Can I Use Strymon Iridium?

On Stage

Want to play live with the exact same tones that you use at home or in the studio? Or have access to multiple amp and cab setups without having to lug them on stage? Leave your amps at home, and connect Iridium directly to the house PA system.

Going direct eliminates the need to mic an amp, giving sound engineers the option to send your amp and cab tone directly to a wedge or in-ear monitors. Instant adjustments to your tone are right there on your pedalboard, only a footswitch away. With Iridium, there are no menus to wade through - just familiar, responsive amp-style controls for instant, easy adjustment.

In the Studio
Iridium provides gorgeous, iconic amp tones, stunningly realistic stereo cabinet impulse responses, and natural room ambience—essential elements for recording guitar in the studio.

Place Iridium at the end of your effects chain and capture stereo amp and cab tones direct into your recording interface. Or, place Iridium before your delays and reverbs to allow those time-based effects to occur post amp and cab.

Skip the hassle of miking up your amps or having to crank them up to get the tone you desire. Instantly audition amps and cabs with the flick of a switch.

At Home
You can’t always crank up an amplifier when you want to play in your living room or rehearse at home. Plug your favorite set of headphones into Iridium’s headphone jack and get immersed in the sounds of iconic amps and cabs in a natural sounding room.

Integrate Iridium into your pedalboard by placing at the end of your chain or before delays and reverbs, and experience your entire pedalboard tones directly in your headphones.

More Use Cases
Iridium also allows for less common use cases. Want to use Iridium’s amplifiers but not the IR cabinets? Select Iridium’s Cab Bypass mode, and connect the output(s) to the effects return or power amp input on a guitar amplifier.

Want to use Iridium’s IR cabinets but not the amps? Engage Iridium’s Amp Bypass mode, and connect a preamp or preamp pedal (such as Riverside) to Iridium’s input.

Because the purpose of Iridium is to generate amp and cabinet tones, the primary use case is for direct situations. It’s not recommended to connect Iridium to a guitar amplifier.
