Chapter 1 - OVERVIEW
Congratulation on your purchase of Cabzeus!
Cabzeus is a algorithm-based speaker - cabinet - miking
simulator system. Connected direct to your gears this device
enables you to obtain the sound of a miked-guitar amp cabi-
net without the hassle of miking your cabinets. Extending
this basic function, we’ve built into Cabzeus a plethora of
unique and powerful features that goes beyond simple
speaker simulations.

Stereo I/O
Cabzeus has 2 independent channels, each with its own
input, thru, and output. With a special software that we pro-
vide you can freely customize the whole simulation aspects
(speaker type, cabinet type, mic placement, etc.) of each
channel independently. To help you get the most of your
stereo setup, we have also included powerful stereo proc-
essing functions such as :
 adding short delays to one of the channel.
 blending two simulation channels.
 independent volume and phase control.
Presets
When you’ve found your favorite settings you can save them
as presets in Cabzeus. The presets (8 of them) can then be
called using the preset selector knob, an external switchbox,
or a MIDI controller.
Preset 1 - 4 : LED turns Green
Preset 5 - 8 : LED turns Red
Bypass : LED turns off.

Mic Position Knobs
Sometimes you feel that you need to make some adjustment
to the overall tone of your presets while you are away from a
computer, this is where the two brown colored knobs on
Cabzeus come in handy. These knobs control the mic posi-
tion parameters (the same control is found in CabsLab soft-
ware as well).
As a rule of thumb, turn the knob to Center position for a
extended highs and slightly tamed lows, and turn to Edge
position for the opposite tonal effect.
Operating the knobs
The two knobs have a lock mechanism which prevents
changes due to accidental movements.
After turning the mic position knobs : press the middle button
once (do not hold) to actuate the change. The change will
immediately take effect.
If you want to save the changes you made into the current
preset : press and hold the middle button, until the preset
LED flashes 3x.
Press (do not hold) to actuate the change.
Press and hold to save the change

Input Connections
Cabzeus has a pair of inputs, and each one has its dedi-
cated Thru output. A wide array of input sources can be
connected to the inputs, ranging from your favorite stomp-
boxes, preamps, your head amp's speaker out, to any music
player (see Chapter 3 : Application Ideas).
What’s the purpose of Thru Output?
As we’ve mentioned, you can connect the speaker out of
your amp to the Cabzeus input, however recall that a tube
amp must have its speaker output connected to a speaker or
a load box at all times to avoid damaging its output trans-
former. And since Cabzeus does not function as a load box
you must connect the Cabzeus’ Thru output to a speaker
cabinet or a load box, keeping your tube amp’s safe.
Speaker cabinet or Load box
Tube amp
What’s the purpose of Input Pad?
Input Pad switches allows you to attenuate the input signal
level going into Cabzeus, which may be necessary of you
connect an input source with very high level output signal
such as the speaker out of an amp.
If attenuation is not needed set the switch to 0 dB, in this
case you may use the -30 dB position as a ‘mute’ function.

Chapter 7 - Factory Presets
The pedals comes with 8 factory presets. Storing new pre-
sets will overwrite these. You can use the CabsLab software
to restore the factory presets.

Chapter 5 - M I D I
You can use any standard MIDI controller capable of send-
ing Program Change (PC) messages to accomplish remote
preset change with Cabzeus.
Chapter 6 - Updating Firmware
You can use CabsLab to perform firmware updates.
1. Download the latest firmware updates at :
www.gfisystem.com/cabslab.html

2. Remove power from the pedal.
3. While holding down the middle knob (preset-select knob), apply
power to the pedal. Keep holding the knob down while the pedal
goes through the normal power-up sequence, then release when
when preset-1 and preset-4 LEDs light up.
4. Connect the pedal to your computer’s USB port, then open the
CabsLab software and follow the instruction on the screen.

Converting TRS to XLR.
If you are connecting Cabzeus outputs to an equipment that
do not have TRS input socket you will need to use a cable with
a TRS plug on one end, and an XLR on the other end. Use the
following schematic if you plan to build such a cable yourself.

Cabzeus has two outputs which can operate in balanced
mode or unbalanced mode, depending on the type of plug /
cable you use.

Chapter 3 - Using CabsLab software
Here are some of the things that you can do with CabsLab :
Customize the speaker simulation system algorithms.
Store the customized algorithms to your pedal as presets.
Read the stored algorithms in your pedal and display them
on screen.
Save local presets (favourites) in your computer.
Configure the MIDI channel on your pedal.
Revert your pedal to factory setting.
Update your pedal’s firmware.
Highlights :
Real-time preview as you tweak the parameter controls.
‘Solo’ function for single speaker auditioning or quick A/B
comparison.
Extensive set of speakers simulation system parameters.
Saving algorithms as preset into Cabzeus
(1) Choose the desired preset location
(2) Click ‘Write’

Chapter 4 - Remote Preset Change
There are two ways to perform remote preset change :
1. Using MIDI Controller.
2. Using External Switch.

‘Solo’ Function
One very useful feature that you will find yourself using a lot
is the ‘Solo’ function. When using the Stereo Cabs mode, you
have the luxury to specify different speaker for the Left and
the Right channel. But, often in the process of searching for a
great sounding speaker pair, you would like to be able to
audition only a single speaker in isolation. There are many
ways to accomplish this, but the easiest method is to use the
Solo function.
Activating the Solo function forces both the Left and Right
simulators to use the same speaker selection & cabinet type,
as were set on the simulator side whose Solo function you’ve
just activated. All the other controls are still independent.
Click on the Left speaker icon to
activate/deactivate the Left Solo
function.
Click on the Right speaker icon to
activate/deactivate the Right Solo
function.
Tips : When the Left Solo function is active, activating the Right Solo
function automatically disengage the Left Solo function. This behavior is
very useful for doing A/B comparison when auditioning the many speaker
types!

In CabsLab software :
Use STEREO CABS mode.
The dry signal coming in at the Left input will be processed by the
Left-side simulator, and the
wet signal coming in at the Right input
will be processed by the Right-side simulator.
Use the BLEND sliders to control the dry and wet sound mixture.
Note : the delay / reverb pedal must have ‘
kill-dry ’ feature.
