Connecting Iridium

Iridium delivers responsive tube amp tones, ultra-high quality impulse response speaker cabinets, and natural sounding room ambience. It shines as the centerpiece of many different playing applications.

ON STAGE

HOUSE

PA SYSYTEM

DIRECT

BOX

Connect a pedalboard containing Iridium to a house PA system for excellent repeatable tone, control, and flexibility in a live situation. Monitor through the house monitoring system or in-ear monitors. For a dedicated personal on-stage monitor, connect your pedalboard to a powered full-range speaker.

POWERED

FULL-RANGE

MONITOR(S)

NOTE: Because the purpose of Iridium is to deliver amp and cab tones, it is not desirable to enable Iridium in front of a guitar amp. If you use the same pedalboard both with an amp and in direct situations, simply bypass Iridium when using your board with an amp.

Connecting Iridium (cont.)

IN THE STUDIO

Connect Iridium directly to a recording interface for great guitar tone instantly without the need to set up an amp or microphones.

AT HOME

Connect headphones directly to Iridium to experience immersive classic amp tones in a natural sounding room without an amp

ADDITIONAL TIPS FOR STAGE, STUDIO, AND HOME

Iridium can be used on its own or as part of a pedalboard.

• Place Iridium at the end of your signal chain to capture the sound of the entire pedalboard connected to the front of an amp.

• Place Iridium before time-based effects for a different tonal character if you prefer.

• Use headphones to check out a pedalboard that normally connects to an amp by connecting its output(s) to Iridium.

OTHER WAYS TO USE IRIDIUM

Iridium also allows for specialized use cases.

Amp processing without IR cabs Select Iridium’s Cab Bypass mode and connect the output(s) to the

effects return or power amp input on a guitar amp.

(See page 15 for Cab Bypass mode configuration details.)

IR cab processing without amps

Select Iridium’s Amp Bypass mode and connect a preamp or preamp pedal (such as Riverside) to Iridium’s input.

(See page 15 for Amp Bypass mode configuration details.)

WARNING: Never connect the Speaker Output of a guitar amplifier to Iridium! If you wish to use Iridium’s IR cabs with a guitar amp,

you can either use a line out from the amp or the amp’s effects send. Note that you will still need to connect a load to the speaker output with either of these options. You may also need to set Iridium to Line input level.

(See page 16 for Input level configuration details.)

Non-cab WAV files

It is possible to load any 24bit/96kHz WAV impulse response into Iridium, including impulses of bass cabs, acoustic instrument body resonance, samples of music, etc.

is clean, bright, and mid-scooped, with plenty of headroom. While preserving access to all the tones originally available from the Deluxe’s Normal channel, our amp gives you something extra: a midrange control. With the MIDDLE knob at noon, you get the original fixed-resistor value and standard tonal characteristics of the Deluxe. Turn down the MIDDLE control for a more scooped sound, or turn it up for tweed-era tones.

chime

Based on* the Brilliant channel of a Vox

AC30TB, this amp is jangly

and bright, providing air for subtle passages with a light touch, and bite when you want to dig in. The MIDDLE knob acts a tone cut knob, providing high-end roll-off just before the power tubes, per the AC30TB design. In addition to the full available gain of the original amp, toward the top end of the DRIVE knob’s range of travel, we’ve added a frequency-shaped front end boost to tighten the low end while driving the amp further into saturation.

punch

Based on* a Marshall

Plexi (Super Lead model number 1959), this

powerful amp is meatier, with higher gain than the other two amps, and has a powerful midrange response. This amp features a buttery, smooth overdrive. Setting the DRIVE control at around 2 o’clock gets you the maximum gain the original Plexi design allowed. Turn the DRIVE beyond 2 o’clock to access custom hot-rodded Plexi high gain tones.

A more complete description of these IRs and the original speaker cabinets can be found on Appendix 2. Additionally, the factory installed IRs can be replaced with any 24 bit/96 kHz WAV format IRs using our free Strymon Impulse Manager software available at strymon.net/

Each tone knob on a classic amplifier controls a potentiometer that interacts with the other components that make up the tone stack, creating a complex, interdependent frequency response. Our Matrix Modeling™ process captures all these subtleties, faithfully delivering the unique tonal qualities of each amp type.
