particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
Only use attachments/accessories specified by the manu-
facturer.
Use only with the cart, stand, tripod,
bracket, or table specified by the
manufacturer, or sold with the ap-
paratus. When cart is used: use cau-
tion when moving the cart/appara-
tus combination to avoid injury from
tip-over.
Unplug this apparatus during lightning storms, or when un-
used for long periods of time.
Refer all servicing to qualified service personnel. Servic-
ing is required when the apparatus has been damaged in
any way, such as power-supply cord or plug is damaged,
liquid has been spilled or objects have fallen into the appa-
ratus, the apparatus has been exposed to rain or moisture,
does not operate normally, or has been dropped.

Introduction
FOR UNITED KINGDOM:
FOR YOUR SAFETY, PLEASE READ THE FOLLOWING TEXT CAREFULLY
This appliance is supplied with a molded 3-pin mains plug for your safety and convenience.
The plug contains a 5 amp fuse.
Should the fuse need to be replaced, please ensure that the replacement fuse has a rating of 5 amps and
that it is approved by ASTA or BSI to BSI1362.
Check for the ASTA mark or the BSI mark on the body of the fuse.
If the plug contains a removable fuse cover, you must ensure that it is refitted when the fuse is replaced.
If the fuse cover is lost, the plug must not be used until a replacement cover is obtained.
A replacement fuse cover can be obtained from your local Hammond Dealer.
IF THE FITTED MOULDED PLUG IS UNSUITABLE FOR THE SOCKET OUTLET IN YOUR HOME,
THEN THE FUSE SHOULD BE REMOVED AND THE PLUG CUT OFF AND DISPOSED OF SAFELY.
THERE IS A DANGER OF SEVERE ELECTRICAL SHOCK IF THE CUT-OFF PLUG IS INSERTED
INTO ANY 13 AMP SOCKET.
If a new plug is to be attached to the cord, please observe the wiring code as shown below.
If in any doubt, please consult a qualified electrician.
IMPORTANT - The wires in this mains lead are coloured in accordance with the following code:
Blue: Neutral
Brown: Live
As the colours of the wires in the mains lead of this unit may not correspond with the coloured marking
identifying the terminals in your plug, proceed as follows.
The wire which is coloured BLUE must be connected to the terminal in the plug which is marked with the
letter N or coloured BLACK.
The wire which is coloured BROWN must be connected to the terminal in the plug which is marked with the
letter L or coloured RED.
Under no circumstances should either of these wires be connected to the earth terminal of the three-pin
plug, marked with the letter E or the Earth Symbol .
To replace the fuse, open the fuse compartment with a screwdriver and replace the fuse and fuse cover.

Your Hammond XK-3C Drawbar Keyboard is designed to give you the true and authentic sound of Hammond
Harmonic Drawbars, as well as provide you a large variety of features to allow great flexibility in how you
want to use the keyboard. This Owner’s Manual is designed to explain the operating features of your Hammond
XK-3C as simply and graphically as possible.
Because we want to make this manual, as well as the keyboard itself, as easy to understand as possible, the
explanations in this manual are grouped by subject matter, and not in the order in which they necessarily
appear in the display (the screen in the left of the keyboard front panel). For example, all functions pertain-
ing to Drawbars are grouped together, all Percussion features are treated as a group, and so on.
Also, each feature is treated as an explanation unto itself, and does not require you to already have prior
working knowledge of some other feature. The explanations are presented such that, if you follow the steps,
will be identical to that shown in the manual at that stage of the explanation.
Do not be daunted by the number of steps required to perform each operation. Each step is simple. Simply
bear these things in mind:
1. Read each step carefully.
2. Don’t skip any of the steps.
3. Don’t perform the steps out of sequence.
With these guidelines, you are well on your way to mastering all of the many sounds and features of your
Hammond XK-3C.
IMPORTANT - PLEASE READ

Introduction
BATTERY BACK UP
Your XK-3C uses a battery-backed RAM to remember your changes to the Parameters.
When the battery voltage becomes low, the Display will show:
If you see these messages, you should immediately back up your parameter changes, if you have made any.
If there is no battery installed in the unit, or if the battery is compeletely dead, the Display will show:
After the above message is displayed, the XK-3C will re-initialize itself, and the factory default settings will
be restored (except Combination Presets, Leslie Cabinets and Cutsom Tone-Wheels). Therefore, it is a good
idea to periodically save your data to CompactFlash card.
CAUTION: In order to change batteries, be sure to ask your dealer or store.

MAIN FEATURES
ACCURATELY REPRODUCES THE TONE-WHEEL SOUND.
Your new XK-3C contains (96) independent oscillating digital tone-wheels that accurately reproduce the sound of the
Vintage B-3/C-3.
In addition, this keyboard has full polyphony.
KEYBOARD OPERATES LIKE THE VINTAGE MODELS.
This keyboard operates exactly like the vintage B-3, C-3, etc did.
Presets are selected by means of the Reverse Colored Keys.
Vibrato effects can be selected by the rotary Vibrato control.
The keyboard has Waterfall keys and you can also attach a Leslie Switch (optional) to the front rail as well.
VACUUM TUBE PREAMPLIFIER.
This keyboard has a circuit for a pre-amplifier with 2 characteristically different tubes, a 12AX7 and a 12AU7, so as to
offer a variety of overdrive sounds. The pre-amp circuit consists of dual bands. You can assign bass and treble to
respective tubes, thus can realize purer harmonic sounds. Of course, the general single band operation is also possible.
By adjusting the bias voltage, you can obtain not only the distortion by the general clip but also the nonlinear distortion.
DIGITAL LESLIE / VIBRATO EFFECTS.
The XK-3C keyboard is equipped with a DSP effect generator to simulate the Scanner-Vibrato and Leslie Speaker.
The range of sounds that you can create is expanded by the use of Vibrato and Chorus effects, and by the real sounding
Leslie effects which effectively simulates the rotation of the two Rotors which are present in traditional Leslie.
EQUALIZER AND TONE CONTROL.
A 3-band equalizer and tone-control are now built in. The equalizer can make fine or course tonal adjustments to the
bass, treble, and mid frequency ranges. The tone-control simulates the circuit built in on the vintage B-3/C-3 pre-amp to
obtain a gently-cut treble.
11 PIN LESLIE SPEAKER SOCKET.
Your new XK-3C contains a 11 pin Leslie speaker socket for direct connection to Leslie Speakers.
CAN BE EXPANDED BY USE OF EXTERNAL MIDI PRODUCTS.
You can expand your keyboard by connecting and playing with additional external MIDI equipment.
This includes keyboards, sequencers, etc.
CompactFlash™ CARD
You can use a CompactFlash Card (not included) to save various Parameter files.

16 BASIC HOOK-UP
USING EFFECT LOOP
The Effect Loop is used when you want to connect the Leslie Speaker and the
external Effects module which provides audio prior to the built-in Leslie Effect.
Use effects modules which have a output gain of less than
+4dB.
NOTE: The Effect Loop is inserted between built-in Tube Amp
and built-in Effect (Leslie, Reverb, etc.)
NOTE: Depending on the connected equipment, a setting may
be required for the RETURN jack. (P. 83)
See the figure below for connection.
