● RIGHT IN is an input for the second signal source. A stereo setup can be achieved by simultaneously connecting two mono signal sources to the LEFT IN and RIGHT IN inputs. The Prism II does not support TRS connections. -

● The MIX knob controls wet signal volume. The Prism II was designed as a send effect where the processed signal is mixed in with the dry one; however, you can use the Kill Dry mode to exclude the dry signal from the output. - Page 5 Press and hold the ON/HOLD footswitch: ● While changing the BANK switch position to select a patch bank (each bank holds 3 patches): ○ UP: the Blue bank. ○ MIDDLE: the Red bank. ○ DOWN: the Magenta bank.

ON footswitch. The reverb tails are played till the end, so that the sound doesn’t get cut off abruptly. This mode is highly recommended when using the Prism II as an insert effect (where only the wet signal is needed) or in external wet/dry mixing setups. -

“wah” sounds to complex notch filtering and even phasing. Since each of the two channels has its own set of four filters, the Prism II has a very broad sonic palette. After the two filter blocks, the signal goes into the modulation section. -

The shelving HPF is the final touch to the signal chain. It prevents the Prism II from destroying your lows by reducing the impact of resonant peaks in the lower frequency range. -
Page 9: Modulation Rate Setup
The TAP footswitch and the RATE knob have the same effect on modulation rate, which is determined by the control that has been used last. The TAP footswitch operates in the 0.2 – 2s range. Additionally, the TAP SCALE knob can be used in TP mode to divide or multiply the rate by fixed values between 2x and 32x. -

Red Bank The ON LED glows red. MODE switch position: ● UP: BUTTER The mild filtering in this patch works best with a slow LFO set at medium depth. The algorithm features a bit of upper and lower octave signals. One of the filters moves in the opposite direction to the others, adding some instability to the sound. -

Favorite preset. You can turn off the Favorite function or remap it to the EXT.TAP input through the config file. Read more about Favorite preset settings on the Prism II Support Page. Detune Mode (Gradual Signal Detuning) The Detune Mode only affects the pitch shifting section. -

EXT.TAP — External Control The EXT.TAP jack is an input for external control over the Prism II’s parameters. It has several operation modes: ● Passive controller (normally open momentary button). This mode precisely copies the functions of the TAP footswitch and is active by default. -

Fine-Tuning via USB On the right side of the Prism II, you can find a microUSB port which lets you connect the pedal to your computer. To do that, you need a microUSB cable (purchased separately). The USB port on your computer should be USB 2.0 or higher. -

The #IN_GAIN parameter controls the volume of the input signal. The standard value (1.0) can be increased or decreased. Decreasing the input gain is needed when using the Prism II in the FX loop of your amp or plugging hot signals into the pedal (for line-level signals, the recommended value of this parameter is 0.25). -
Page 16: Input And Output Level Settings
Increasing this value is rarely needed (only when the input signal is very quiet); you can increase the value up to 4.0. We recommend setting the input gain to no higher than 2.0 to avoid clipping. Output level parameter: #OUT_GAIN 2.0 The #OUT_GAIN parameter controls the output volume. -
Page 17: Modulation Settings
#F1_BLEND controls the mix of the dry and filtered signals. At 1.0, the filter is used to the fullest (12dB/Oct); at 0.5, it is used at half the depth (6dB/Oct); at negative values, the filtered signal is subtracted from the dry one (the effect of the filter is inverted). -

LFO Settings The Prism II has three dedicated filter LFOs. The rates for two of the LFOs are set by the RATE knob or TAP footswitch, while the third one is configured separately for each patch and has no physical controls. The DEPTH knob sets filter mod depth. - Page 19 #LFO_ASCALE is the multiplier of all LFO element interactions with a limiter set to 1.0. Increasing the value leads to a greater effect of the limiter on the resulting waveform. Values over 1.0 are recommended. The higher the value, the longer the filters stay at the lowest and highest points of the wave.

We recommend setting the CC message interval to 17-20ms. The Prism II is connected to the MIDI source via a MIDI Type A 6.3mm TRS jack. The wiring scheme is as follows: MIDI 4 (Source) > TRS RING, MIDI 2 (Shield) >... -
Page 21: Updating The Firmware
The current firmware version (1.3) is installed on pedals manufactured after May 1, 2022. If you bought the pedal on an earlier date, we advise that you update the Prism II firmware to the latest version presented on this page. -
Page 22: Specifications
Specifications ● LEFT IN / RIGHT IN: 6.3mm, mono, unbalanced, 1MOhm input impedance. LEFT IN is the main mono input. ● LEFT OUT / RIGHT OUT: 6.3mm, mono, unbalanced, 100Ohm output impedance. LEFT OUT is the main mono output. ● EXT.TAP: 6.3mm, normally open momentary button, MIDI Type A, or 5V analog trigger (S-trig/V-trig) with up to a 2-second interval between two consecutive signals.
