Congratulations on your purchase of the Crash Pad, a faithful reissue of the
Electro-Harmonix Crash Pad drum synthesizer first released in 1980. The Crash
Pad uses analog synthesis techniques–such as resonant filter sweeps of a noise
source–to create a range of drum sounds from cymbals to snares to otherworldly
oscillation sweeps. Trigger the Crash Pad from the on-board push button or an
external, non-MIDI, electronic drum pad. Pass external sounds through the
resonant filter via the auxilliary input. Use the expression pedal/CV input for
external control over the filter in real-time.
SWEEP Controls – Together, these three knobs control the Crash Pad's filter
frequency sweep:
START Knob – Sets the starting point of the frequency sweep. Filter
sweeps can begin anywhere from 250 Hz at full counterclockwise to 7.5
kHz at full clockwise.
STOP Knob – Sets the end point of the filter's frequency sweep.
Sweeps can end anywhere from 50 Hz at full counterclockwise to 7.5
kHz at full clockwise.
TIME Knob – Controls how long it takes to sweep from the START
frequency to the STOP frequency. As TIME is turned clockwise, the
sweep time slows down. Sweep time ranges from 40 ms to 4 seconds.
SENS. Button – Controls the sensitivity of the Crash Pad to an external trigger.
Sensitivity is high in the down position and low in the up position. We
recommend you start with the high setting because smaller amplitude pulses are
required to trigger the Crash Pad as compared to the low setting. Additionally,
the amplitude of the external trigger signal changes the Crash Pad's output
volume and start frequency to a limited degree so that hitting your drum pad
harder may produce a louder output signal.
RESONANCE Knob – Adjusts the resonance (or Q) of the low pass filter. As
you increase RESONANCE the filter's Q increases. The filter begins to self-
oscillate at around 3 o'clock on the RESONANCE knob.
VOLUME Knob – Controls the volume of the output signal. As VOLUME is
turned clockwise, the output volume increases.

Summary of Contents for Electro-Harmonix CRASH PAD
- Page 1 Sweep time ranges from 40 ms to 4 seconds. SENS. Button – Controls the sensitivity of the Crash Pad to an external trigger. Sensitivity is high in the down position and low in the up position. We recommend you start with the high setting because smaller amplitude pulses are required to trigger the Crash Pad as compared to the low setting.
- Page 2 The AUX IN jack allows external instruments and sound sources to be filtered by the Crash Pad, turning it into a useful resonant filter effect in its own right. Use control voltage (CV) or an expression pedal in conjunction with an external sound source to expand the Crash Pad’s filter effect even further.
- Page 3 OUTPUT jack. When the DIP switch is set to the ON position (towards the edge of the unit) and a plug is inserted into the EXP. PED jack, the Crash Pad’s volume envelope is disabled, allowing the Crash Pad to continuously send the output of its filter to the OUTPUT jack.
- Page 4 WARRANTY INFORMATION Please register online at http://www.ehx.com/product-registration or complete and return the enclosed warranty card within 10 days of purchase. Electro-Harmonix will repair or replace, at its discretion, a product that fails to operate due to defects in materials or workmanship for a period of one year from date of purchase.
