INTRODUCTION

The Warm Audio RingerBringer accurately recreates the ultimate all-analog ring modulation effect used for experimental tones. With LFO, MOD, FREQUENCY & RATE controls, you can generate layered frequencies and harmonics, explore a wide range of sonic possibilities for guitar & beyond, and design your own sounds from the ground up. Sporting premium components including hand-selected op- amps and transistors, the RingerBringer delivers true-tospec performance of the boutique original.

PEDAL LAYOUT & CONTROLS

1. MODULATION CONTROLS
   • Mix: The MIX control on RingerBringer allows crossfade the dry and wet (modulated) signals. Turning the knob clockwise will increase the percentage of “wet” effect tone vs. dry signal, adding wobble and pitch shift depending on other pedal settings. 100% counterclockwise yields zero modulation and 100% clockwise yields a fully wet signal.
   • Frequency: The Frequency control on RingerBringer determines the frequency of the carrier oscillator, affecting the pitch and harmonic content of the ring-modulated output. As you increase the frequency (clockwise), you will begin to hear the distance between the harmonic content as shifted pitch. The lower the setting, the more it sounds like tremolo, at higher frequency settings, more harmonic dissonance and pitch shifting will occur.
   • LO/HI Switch: The LO/HI switch sets the range of the frequency settings for the carrier oscillator inside RingerBringer. The “LO” setting range is [0.6 Hz to 80 Hz] and the “HI” setting range is [30 Hz to 4 kHz]

2. LFO CONTROLS
   A NOTE ON THE LFO-SIDE OF THE WA-RB
   LFO, or Low Frequency Oscillator, is typically used to generate effects like vibrato and tremolo. RingerBringer features a dual-waveform, voltage- controlled LFO that modulates the carrier oscillator frequency.
   • Amount: The AMOUNT knob on RingerBringer sets the degree to which the LFO waveform modulates the frequency of the carrier oscillator. When turned counterclockwise, there is no frequency modulation from the LFO. Rotating the knob fully clockwise,however, results in a frequency modulation spanning three octaves for the carrier oscillator.
   • Rate: The RATE knob on RingerBringer controls the speed at which the LFO oscillates. This knob covers a frequency range of 0.1 Hz – to 25 Hz, with 1 Hz being equal to one cycle per 10-second interval.
   • Sine/Square Switch: The SINE/SQUARE switch on RingerBringer allows you to choose between the square waveform and the sine-like waveform generated by the LFO. The square wave will produce fluttering/trembling effects, while the sine waveform creates vibrato and more gradual pitch-altering tones.

3. DRIVE CONTROL
   The DRIVE knob on RingerBringer fine-tunes the input gain, allowing precise adjustment for a variety of instruments or line-level signal sources. Turning the knob clockwise will INCREASE the amount of gain applied. Weaker signals will need more turning of the knob while stronger signals can afford less use of the knob. The DRIVE control is always on, even when RingerBringer is bypassed, so setting this control acts as a unity gain for your signal while RingerBringer is in the chain. You can also push the drive knob into harmonic overdrive and even distortion as well.

4. LEVEL LED The LEVEL
   indicator gauges the strength of the adjusted input signal via the DRIVE control. It transitions from off to green, then yellow, and finally red as the signal strength increases. Weak signals won’t activate the indicator LED at all. A green light signifies a signal below the threshold where audible distortion is expected. A yellow color indicates subtle harmonic distortion, adding a more round analog tone. When the signal intensifies to reach red, distortion at the output becomes more obvious and will sound like an overdrive pedal inside RingerBringer.

5. LFO LED
   The LFO LED corresponds with the sine LFO waveform, offering a visual cue for the speed of the LFO.

6. BYPASS LED:
   A red light indicates that the RingerBringer is bypassed, while green indicates it’s part of the signal path. Stomping the pedal to a green LED color means the pedal is on and in the signal. Note that the drive control works even in bypass mode.

PEDAL INPUTS & OUTPUTS

1. Audio In: ¼” AUDIO IN accepts any line/instrument-level audio signal from -16 dBm to +4 dBm. Input impedance is 1 MΩ.
2. Audio Out: ¼” AUDIO OUT is -4 dBm nominal output level with 600Ω impedance.
3. LFO OUT: LFO OUT supplies the ±1.5-volt LFO voltage (Output impedance = 600Ω) to use with other voltage-controlled equipment.
4. CV/Expression Ins/Outs [RATE | AMOUNT| MIX | FREQ]: Series of stereo ¼” jacks that accept control voltages or expression pedals from two or three-circuit ¼” jacks assigned to their respective parts of the RingerBringer circuit. Ex: Adding an expression pedal to the MIX input will allow the user to manually crossfade the wet/dry signal on WA-RB.
5. Carrier In: The CARRIER INPUT (1 MΩ impedance) enables the application of an external -4 dBm (0.5 volt RMS) signal to the ring modulator. When in use, this effectively replaces the carrier oscillator.
6. LFO Out: The LFO OUT jack supplies the LFO voltage (±1.5 volts) for external use by other voltage-controlled equipment.
7. Carrier In/Out: CARRIER OUT supplies the ±1.25-volt carrier signal to use with other equipment. Output impedance = 600Ω.

POTENT PAIRINGS

While ring modulation is a vast platform for audio experimentation all by itself, adding other effects and tinkering with pedal order can open up a new world of sonic inspiration.
DELAY: Experiment with adding delay to your WA-RB signal chain. Adding delay after WA-RB will generate repeats of your modulated signal, causing interesting resonance with the new harmonics generated by WA-RB.

DELAY TIP: Consider swapping out cleaner digital delays with tape and echo units for even more lo-fi saturation and modulation. Some of the “flutter” effects of these pedals will interact with the modulated sound coming from WA-RB, and the overall tone will likely have a more rounded, ana- log sound to it.

FUZZ & DIRT: Putting a fuzz or overdrive pedal in front of the WA-RB can yield very interesting results. Sending a signal with harmonic overtones INTO the WA-RB before any internal drive or modulation has been applied can create even more “unhinged” especially as the Frequency control is dialed up into pitch-shifting madness.

FUZZ/OD TIP: To make sure you’re hearing the separation of the external fuzz vs. the WA-RB drive control, start with the external fuzz OFF and set the DRIVE on WA-RB while in bypass mode. When adjusting the drive, keep the DRIVE LED green to make sure you’re at max gain without audible dis tortion from the WA-RB circuit. When you’re able to play at normal intensity and keep the light green, fire up the pedals and know that all the distortion you hear will be coming from the external fuzz/od/distortion pedal in your chain.
