Electro Harmonix Nano Pulsar Variable Shape Stereo Tremolo effectpedaal EHX Nano Pulsar manual

Congratulations on your purchase of the Nano Pulsar, a variable shape stereo
tremolo and panner effects pedal. Connected in mono, the Nano Pulsar is a
tremolo that allows signicant control over the shape of the modulating
waveform. Connect the Nano Pulsar in stereo (each output to a separate amp/
mixer channel) and you have a panner pedal that will send your instrument

back and forth between two amps with the same control over waveform shape.

So, while one amp is fading up in volume, the other will be fading down in
volume or even more dramatic: while one amp is on, the other is off. But that’s

not all! Higher settings of the DEPTH knob put the Nano Pulsar into warp mode

where the signal’s volume modulates asymmetrically producing rhythmic,

out-of-phase tremolo effects.

Operating Instructions

Connect your guitar or other instrument to the INPUT jack on the Nano Pulsar
and the MONO/L OUTPUT to your main amp. If running the Nano Pulsar in
stereo, connect the Right OUTPUT jack to another amplier. Apply power if

needed; your Nano Pulsar might already have a 9V battery installed. Press

the footswitch to ensure the STATUS LED is lit, now your Nano Pulsar is

ready to go.

For a nice starter setting, turn all knobs to their 12 o’clock positions and set

the toggle switch—centered within the knobs—to the Triangle position. This
setting will yield a deep, smooth tremolo at a medium rate. Lower the DEPTH

knob for a shallower tremolo effect; play with the RATE knob to hear the
full range of modulation speed on tap; and of course, adjust the VOL knob

for more or less volume at the output jacks.

Controls and Connections

1. VOL Knob Adjusts the overall output level of the effect. As VOL is turned clock­wise, the output gets louder. The VOL knob offers up to 12dB of volume boost
depending on the settings of the other controls. When VOL is turned fully counter-

clockwise the effect output is silenced.

2. SHAPE Switch Selects between Triangle and Square Wave modes. See more on
Shape in the SHAPE knob section.

3. SHAPE Knob Further adjusts the tremolo’s modulation waveform shape.
Triangle Wave Mode The modulation waveform is triangle wave based,

resulting in smooth volume modulation. As the SHAPE knob is turned

clockwise from the minimum position to the center, the waveform morphs

from rising sawtooth to triangle. Turning SHAPE further clockwise from the

center position to maximum, the waveform continues to morph from triangle
to falling sawtooth. Please note: the triangle shapes are reversed out of the

Right OUTPUT jack. For example, at the minimum SHAPE setting, the right

output will be a falling sawtooth.

Square Wave Mode The modulation waveform is square wave based, re­sulting in sharp, on/off volume modulation. As the SHAPE knob is turned
clockwise from minimum to maximum, the modulating waveform’s pulse
width increases from a narrow pulse to a wide pulse width. Near the knob’s
center position is square wave modulation where the tremolo volume is
loud and quiet in equal amounts. Please note: the square shapes are re­versed out of the Right OUTPUT jack. For example, at the minimum SHAPE

setting, the right output will be a wide pulse width.

4. DEPTH Knob Adjusts the amount of tremolo that will be applied to your signal.

As DEPTH is turned clockwise from minimum to maximum, the amount of the
tremolo effect increases. Maximum tremolo—greatest dynamic range from loud­est to quietest—occurs when the DEPTH knob is set to approximately 1 o’clock. As
DEPTH is turned further clockwise past 1 o’clock, the tremolo begins to warp by

modulating between positive and negative phase with an asymmetric or rhythmic

feel. Set DEPTH to approximately 1 o’clock to obtain the widest stereo eld

when the Nano Pulsar is used as a stereo panner.

5. RATE Knob Adjusts the speed of the tremolo or pan effect. As RATE is turned

clockwise the modulation rate increases. The range of modulation speed is ap-

proximately 20 seconds to 30 Hz.

6. FOOTSWITCH and STATUS LED – Press and release the footswitch to toggle

between buffered bypass and effect mode. When in effect mode, the Status LED
is lit and pulses at the same rate as the effect. The Status LED is off in buffered

bypass mode. The Nano Pulsar powers up in bypass mode.

7. INPUT Jack Audio input to the Nano Pulsar.

8. MONO/LEFT OUTPUT Jack Connect this ¼” mono jack to your amplier’s input.

When using the Nano Pulsar as a mono device we recommend you use the MONO/L
jack so that the SHAPE knob description on the previous page corresponds to

what you hear.

9. RIGHT OUTPUT Jack Connect this ¼” mono jack to your second amplier’s input.

When using the Nano Pulsar as a stereo panner, use the R OUTPUT jack for your
second channel. You can connect only to the RIGHT OUT jack if you like; the tremolo
effect will be the same as from the LEFT OUT jack but the SHAPE waveforms are re­versed. For example, when the SHAPE knob is set to maximum, tremolo modulation
out of the Right Output will either be a rising sawtooth or narrow pulse width.

10. 9V Power Jack – An optional 9VDC, center-negative power supply can be connected

to the power jack to provide power without a battery. The Nano Pulsar requires
30mA at 9VDC on a center-negative plug. Do not exceed 12VDC at the power jack.

When using a 9V battery, plugging into the INPUT jack activates power. The input cable

should be removed when the unit is not in use to avoid running down the battery.

To change the 9-volt battery, you must remove the 4 screws on the bottom of
the Nano Pulsar. Once the screws are removed, you can take off the bottom plate
and change the battery. Please do not touch the circuit board while the bottom
plate is off or you risk damaging a component.
