1. POWER
To power the unit, insert 4 AA batteries (included) or connect a
Source Audio 9V power supply to the 9V DC jack (A).
2. GuITAR/AuDIO cONNEcTIONS
Next, plug your bass guitar (or other instrument) into the jack
labeled GUITAR IN (B) via a standard ¼-inch cable. Connect your
amp (or other audio device) to the GUITAR OUT (C) jack, again with a
standard ¼-inch cable. Both input and output are mono signals.
Note: The unit will not power up until a ¼-inch plug is inserted into the
guitar input. This is to conserve power when the unit is running on batteries.
Don’t forget to unplug the cable from the input when the unit is not in use—
otherwise the batteries will continue to drain.
3. SENSOR IN (optional)
To use your Bass Envelope Filter with a Hot Hand sensor: Connect
the sensor to the SENSOR IN (D) jack and follow any instructions
supplied with the sensor.

EffEcTS
Here are some brief technical
descriptions of the lter effects
included in the Bass Envelope Filter.
Some of the lter types are intended
to approximate, but not exactly copy,
some common and well-known bass
envelope lter effects. These are
marked below.
details.
SPEED
The speed knob controls the attack
and decay time of the envelope follower. The range of the speed control
is divided into two parts. To the left
fREQuENcY
The frequency knob sets the center
frequency of the lter sweep. Turning
the knob counterclockwise will result
in the lter moving over lower frequencies for a darker sound. Turning
the knob clockwise will result in the
lter sweep moving over higher frequencies, which will create a brighter
and thinner sound.
SWEEP RANGE
The sweep range knob controls the
direction and breadth of the lter
A
sweep. To the right side of the knob,
marked as UP, the lter will move in
a positive sweep from low to high with
greater range as you turn the knob
further to the right. To the left side of
the knob, marked as DOWN, the lter
will move in a negative sweep from
high to low with increased range as
of the midpoint (12 o’clock) both the
attack and release times of the envelope detector are controlled together.
They range from slow when fully
turned to the left, to fast when set
toward the midpoint. As the knob is
turned to the right past the midpoint,
the attack is xed at the fastest setting while the decay time gets slower.
In Hot Hand mode, the knob controls
the response of the motion sensor.
FLAIL being the slowest and PICK
being the fastest response. See
the Use with Hot Hand section for
more details.
Note: The envelope follower signal
can be reset to zero by a very brief
moment of silence, allowing the next
note played to experience the full
sweep of the envelope all the way
from zero.
ON/Off
The ON/OFF switch engages or disengages the effect. When the effect is
engaged, the ON/OFF LED will be lit.
The LED will be off in bypass mode.
The ON/OFF switch is also used to
start the calibration routine when the
EFFECT knob is set to CALIBRATE.
2 POLE fILTERS
01: Resonant low pass. A at response
at low frequencies, rising to a resonant
peak, and then falling at 12 dB/octave.
Low resonance (low Q). This setting
can create sounds similar to the 3leaf
Groove Regulator
02: Resonant low pass. High resonance
(high Q).
03: Notch, Resonant low pass. The
frequency response begins at, then has
a deep notch, then back to at, and then
a resonant peak followed by a 12 dB/
octave fall. This settings creates sounds
similar Pigtronix EP-1.
04: Notch, Notch, Resonant low pass.
Same as 03, but with two notches.
05: Peak, Notch, Resonant low pass.
A resonant peak, followed by a notch,
followed by a resonant low pass.
06: Resonant low pass, Peak, Peak.
As the response of the low pass lter
falls, the fall is interrupted
by two peaks. The low pass resonant
peak moves in the opposite
direction from the additional higher
frequency peaks.
07: Two resonant low pass lters in
parallel.
4 POLE fILTERS
08: Resonant four pole low pass. Like
the two pole low pass, but after the
resonant peak, the signal falls at
24 dB/octave.
09: Four pole low pass with two resonant peaks. The resonant peaks are
separated by 1.3 octaves.
10: Peak, Four pole low pass.
A four pole low pass with an extra peak
at a lower frequency than the resonant
peak.
11: Four pole low pass, peak.
A four pole low pass with an extra
peak at a higher frequency than the
resonant peak.
SINGLE PEAK
12: Peak. The frequency response is at,
except in the region around the peak.
Moderate Q.
13: Peak. As above, with higher Q.
These two settings can be used to
approximate the low and high Q sounds
of the MXR Bass Envelope Filter.
TRIPLE PEAKS
14, 15: Three peaks moving together.
16, 17: Three peaks moving in opposing
directions.
PEAKS AND NOTcHES
18: Peak, Notch, Peak.
19: Notch, Peak, Notch.
PHASERS
20: Notch, Notch. A pair of frequency
response notches creates a
standard two notch phaser. There
is a little feedback to boost the
non-notched frequencies.
21: Notch, Notch, Notch. A three notch
phaser with some feedback.

fEATuRES
The Soundblox Bass Envelope Filter
is a new type of envelope lter effect.
The unit features multiple lter types
ranging from classic to modern
and beyond which are all controlled
by a exible envelope follower. An
envelope follower is an algorithm
that responds to the amplitude (or
volume) of the incoming signal and
creates a control signal based on the
input level. This control signal is used
to “move” or modulate the lter to
create a wah-like effect. Additionally,
the lter effects can be controlled
by a Hot Hand Motion Sensor. Either
a wired or wireless sensor can be
plugged into the sensor input on
the back panel. When a sensor is
plugged in, the unit goes into “Hot
Hand Mode” and the controls take on
slightly different functions. Also, the
calibrate feature is intended for use
with the “Hot Hand Mode” only.
HOT HAND
READY
While the primary function of the
Bass Envelope Filter is as a standalone effect pedal you also have the
option of exploring some additional
functions by plugging in a Hot Hand
sensor. When a sensor is plugged in
the unit goes into Hot Hand mode.
In Hot Hand mode, the controls take
on some secondary functions. These
are shown by the white text beneath
main label of the knobs.
Hot Hand Basics
The Hot Hand motion sensors are
sold separately and come in either
wired or wireless versions. Both will
work with the Bass Envelope Filter.
Additionally, the SENSOR IN jack
will be compatible with any future
Source Audio sensors.
The Hot Hand ring contains an
accelerometer that responds to
acceleration and is not based on any
type of proximity to the guitar. By
moving your hand or by changing the
position of your hand you can modulate the effect. For a good description
of Hot Hand Theory, download the
Hot Hand Motion Controlled Wah
Filters manual. It is available at
www.sourceaudio.net. Keep in mind
that the Bass Envelope Filter can only
use the x-axis of the ring sensor.

uSE WITH
HOT HAND
Depth
In Hot Hand mode, the
RANGE knob becomes the depth of
the effect based on the sensor input.
It can alternatively be thought of as a
gain control for the Hot Hand signal.
Increasing the depth will cause the
lter to move more based on smaller
motions of the sensor. Decreasing the
depth will decrease the movement
of the lter. In Hot Hand mode, the
depth increases turning the knob to
the left or right except that in the ‘+’
region the motion of the lter will be
from low to high and in the ‘-‘ region
the lter will move from high to low.
This effectively inverts the Hot Hand
signals.
Motion Control
The
SPEED control becomes the
MOTION control in Hot Hand mode
and is used to smooth out the input
from the sensor by ltering out fast
changes in the signals. The amount
of smoothing is controlled by the
knob. Turning the knob towards
provides the most amount of smoothing and the effect will now only react
to large, slow motions of the sensor.
This is useful when you only want the
effect to respond to large, deliberate motions. Turning the knob all
the way to
PICK sets the smoothing
at a minimum. This means that fast
changes in the sensor signal will be
applied to the effect. The motions
created from normal picking will be
enough to move the lter. This may
cause the sound to be too “jittery”,
in which case, turn the knob towards
STRUM and FLAIL to get the desired
response. The
nice compromise that allows some
moderately fast motions through
without being too jittery.

Calibration
The Bass Envelope Filter has a
calibration feature which is only used
in Hot Hand mode. However, calibration is not required before use. The
calibration feature allows you to set
the midpoint of the lter sweep for
any position of your hand. Depending
on your playing style, you may nd it
useful to try some different calibration positions. The most common use
of calibration is setting your resting
hand position on the guitar to be the
midpoint of the lter sweep. Calibration can also be useful if you are
putting the sensor on a headband or
other alternate locations.
To perform a calibration
• Turn the EFFECT knob to the
CALIBRATE position.
• Hold the sensor in the desired
position.
• While holding the sensor steady,
press the
wait for 1 second.
• Turn the EFFECT knob away from
calibrate to use your new calibration setting. Note: Calibration
settings will be saved between
power cycles.
If you have trouble with calibration
and need to get back to the default
setting, place the sensor on a at,
level surface with the blue LED facing
down and run the calibration procedure again.
