CRASH PAD
Electronic Crash Drum
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 onboard push button or an external, non-MIDI, electronic drum pad. Pass external sounds through the resonant filter via the auxiliary input. Use the expression pedal/CV input for external control over the filter in real-time.
CONTROLS
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 endpoint 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.
DECAY Knob — Each time the Crash Pad is triggered, an internal volume
envelope is activated. The DECAY knob sets the time it takes for the volume
envelope to fade out the triggered sound. With DECAY at full counterclockwise,
the envelope produces very fast click-type sounds. Turn up DECAY to the
maximum to allow the Crash Pad’s output to ring out for a lengthy 6 seconds.
POWER LED — Lights up when the Crash Pad is powered up.
TRIG LED — Briefly lights when the Crash Pad is triggered from either the
onboard push button or an external trigger.
PUSH BUTTON TRIGGER — The white button at the center of the logo. This
push button triggers the Crash Pad. Push this button to create amazing sounds.
OUTPUT Jack — This VC jack is the audio output from the Crash Pad. The
output impedance varies from 10052 to 251(Q. Please note: when powering
from a battery, inserting a plug into the OUTPUT jack turns on the Crash Pad.
Remove the plug from the OUTPUT jack to prolong battery life.
EXT. TRIG Jack — This VC jack is the input for an external trigger. The
Crash Pad triggers positive-going pulses or clock signals ranging from 3V to
15V or +/- 3V to +/-8V. Nearly all types of gate, clock, and trigger signals
that fall within this voltage range will trigger the Crash Pad. Some examples
of acceptable trigger signals include electronic drum trigger pads, an
electronic pulse (as produced by the EHX Clockworks), a clock generator (as
produced by the EHX 8 Step), gate signals from synthesizers such as V-Trigger,
or sync signals from drum machines. The input impedance is 2MQ.
AUX IN Jack — This VC jack is the auxiliary input for an external sound
source. The signal present at the AUX IN jack connects to the Crash Pad’s
resonant filter and then into the Crash Pad’s volume envelope. When a plug is
inserted into the AUX IN jack the Crash Pad’s internal noise source is
disconnected from the filter. The input impedance is 10MQ.
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.
EXP. PED Jack — Connect an expression pedal with a TRS plug to this jack
to control the filter sweep with your foot. Additionally, the EXP. PED jack
can be connected to a CV source using a TS plug; the acceptable control
voltage range is OV to 5V. Some suggested Expression Pedals: EHX Expression
Pedal, M-Audio® EX-P, Moog® EP-2 and EP-3, Roland® EV-5 or Boss® FV-500L. The
polarity of the expression pedal’s plug must have SLEEVE connected to the heel
position (usually GND), RING connected to the toe position, and the TIP
connected to the wiper. Although the nominal expression pedal impedance is
10k.Q, most other values will work fine. Please do not go below 61‘2 on your
expression pedal’s potentiometer impedance.
EXPRESSION PEDAL FIXED VOLUME DIP Switch — Inside the Crash Pad is a DIP
switch labeled 53, EXP FIXED VOLUME; it is located just above the 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. This setting lets you use the Crash Pad’s filter
without providing a trigger signal. Please note: the DECAY knob is inactive
when the DIP switch is set to ON. 53 is set by default at the factory to the
OFF position (towards the center of the unit). In the OFF position, a trigger
action is required to use the Crash Pad. The fixed volume setting is only
available when a plug is inserted into the EXP. PED jack and 53 is set to ON.
9V Power Jack — Although the Crash Pad accepts 9V Batteries, EHX supplies
your Crash Pad with an Electro-Harmonix 9.6DC-200BI power supply. Plug the
output of the AC adapter into the 9V power jack located at the top of the
Crash Pad. The Crash Pad draws 22mA at 9VDC with a center-negative plug.
Please do not exceed 10VDC on the Crash Pad’s power jack.
REMOVING BOTTOM COVER – CHANGING THE BATTERY
To replace the 9V battery or change the setting of 53, remove the 4 screws on the bottom of the Crash Pad. Once the screws are removed, take off the bottom plate. While the bottom plate is off you risk damaging a component. Please do not touch the circuit board, except to change the setting for 53, the EXP FIXED VOLUME switch.
