Introduction
Thank you very much for choosing an Uhl-Instruments X3-1 or X3-2. You have obtained a state-of-the-art model
of a vintage organ. We recommend that you read the entire manual carefully to take full advantage of all the
functions of your new Uhl-Instruments X3. Please keep this manual for later reference. We also recommend you
to keep all packaging to protect the instrument if transporting is required.
X3-1 and X3-1 have identical connection jacks and controls. Hence both models are referred to under
the name X3 in the following.
X3 Overview
The HOAX sound engine of the Uhl-Instruments X3 organs fully matches the vintage electromagnetic organ
sound, including rotary cabinet, spring reverb and pedal sustain. This sound engine features completely new
principles of electronic sound generation. An exact physical model of the famous vintage organ delivers the
most authentic organ voices imaginable. It doesn't use computers, signal processors, sample players or analog
electronics. Instead, the layout of vintage organs has been transferred to a detailed physical model. HOAX does
not emulate the sound; it rather creates the sound in real-time –just like real magnetic wheels.
The percussion has that gorgeous round wooden "clonk" (remember "Child in Time"?). The smacking produced
by the tone generator gets under your skin, especially in connection with percussion on. We recreated even the
smallest details of the finest sounding vintage organs. No computers, no samples and no DSPs are used to
comprehensively mimic all the characteristic sound details. To take a single example: the Chorus/Vibrato can't
be distinguished. No wobbling! Switch it on and enjoy that silky C/V shimmer, long-desired by clonewheel
players.
The innovative sound generation boast a great number of advantages: there is absolutely no perceivable key-to-
audio latency since the 91 magnetic wheels are continuously running, just like in a magnetic wheel generator.
Polyphony is unlimited. No lost notes, even if all keys are pressed simultaneously. And the total absence of
unwanted phase relations between the magnetic wheels makes the sound of the Uhl-Instruments X3 so
incredibly lively and natural.
All the sought after „shortcomings“were taken over as well:
Leakage /crosstalk, magnetic wheel slip and flutter, harmonic distortion and output voltages of pickups and
filters - and of course the typical „keyclick". The X3 keyclick is not just an added noise signal. It is dynamically
produced by random "chatter“of key contacts, dependent on key velocity. Other features are: Chorus/Vibrato
based on a digitally recreated LC delay line, Percussion in all variations, foldback and precise tapering. Drawbar
response is immediate and responsive, just like a vintage organ.
Warning! Playing an Uhl X3 organ is highly addictive!

Backpanel Connections
Expression-Pedal: The pedal jack can be used with a Yamaha FC7 or similar expression pedals
Rotary SLOW/FAST: Supports latch mode footswitches with stereo plugs. Momentary switches are not
supported. Pin configuration: Tip = SLOW/FAST, Ring = RUN/STOP
2 x MIDI IN: These inputs can be used to connect a controller keyboard for Lower Manual (Midi channel 2) and
a Midi pedal for pedal bass (Midi channel 3).
l
Main-OUT L + R: Standard audio output for standard instrument cables (TS Male ¼). The audio routing can be
configured with the display/menu-panel (see page 20).
AUX L + R: Auxiliary audio output for for standard instrument cables (TS Male ¼). The audio routing can be
configured with the display/menu-panel (see page 20).

Connecting the Power Cable
The X3 runs on AC power: 100, 120, 230, or 240 volts at 50–60 Hz. The voltage level is set automatically. Make
sure the X3 power switch is set to off before you connect the power cable. Plug the cable into a grounded outlet
only.
Make sure that your power outlet delivers an appropriate voltage level as described above.
The power cable may vary according to the country where you bought your X3. Do not manipulate the
cable or plug. If your power source does not have a standard grounded outlet, you should have a proper
grounding system installed by an expert before using the X3. This will reduce the risk of a shock.

Startup
Connecting the Power Cable:
Make sure the power switch (see page 7)
10
is set to OFF before you connect the power cable at the X3.
Plug the power cable into a grounded outlet only.
The X3 runs on AC power: 100, 120, 230, or 240 volts at 50–60 Hz.
Audio Connections
Make sure your sound system is at a safe volume level. Also make sure that the X3’s
VOLUME knob (on the far left side of the front panel) is all the way down.
Plug in a pair of stereo headphones or run two standard 1/4‐inch instrument cables from the
MAIN outputs of the X3 to your amplifier or mixer for stereo. Use only one of the two outputs for mono.
AUDIO-Jacks:
The X3 features two pairs of audio jacks, MAIN-Out und AUX-Out ( see page 6) and the 11PIN-Jack (see page
7 +11). Thes are standard ¼ inch jacks. The audio routing can be configured with the display/menu-panel
(see page 20). The position of the symbol in the display also indicates at which output jacks, for example L
/ R was routed:
The left side of
Display shows
Allways:
MainOut 1+2
MainOut L MainOut R AuxOut 1 AuxOut 2 +B = alle Ausgänge mit Pedalbass
+ 11Pin
L/R = is always with internal Rotary Stereo-Simulation (left and right),
and always with Amp 122-Simulation (Overdrive)
ORG = pure organ signal as G-G OUT of B3 without Amp122 –Simulation (Overdrive)
AMP =pure organ signal without internal Rotary-Simulation, with Amp 122-Simaltion (Overdrive)
PD = Bass-Pedal
+B = with Bass Pedal on all outputs
The bass pedal can also be output quite separately (PD –for example here on AuxOut2)
If the "+ B" does not appear, the pedalboard is routed separately and is not present in L / R, AMP and
ORG and just comes on „PD"
MAIN-Out und AUX-Out jacks can be used with professional audio equipment like active speakers, mixers,
PA, multicore /DI-Boxes, rotary cabinets (1/4 –inch plugs) and other such audio devices.
