Crate DXJ112, SVT400T Operation Manual

W

elcome. Please, Read This:

We at Crate extend our sincere “welcome” into a whole new world: a world where the
legendary performance of a musician-made Crate amplifier combines with the wonders of
digital amp modeling and effects. We bring you the only amplifier you’ll ever need: the
Crate DXJ112. The heart and soul of sixteen different amplifiers have been captured
through the miracles of digital software engineering and placed into the DX amplifier. Not
only does the amp sound like the originals, it performs like the originals, with the same
tones and character of all your favorites – from vintage British grit to today’s heavy metal –
with a wide variety in between.

Along with digital amp modeling comes sixteen digital effects, all designed to rock your
world from here to Sunday. And, you can tweak each effect to your heart’s content!

Got your own favorite effects? Not to worry – the DX amps have stereo line in and line
out jacks for use as a stereo effects loop, or for connecting to an external stereo power
amp. It’s like having your cake and eating it, too – with extra icing!

The DX amplifier is programmable and can be controlled in a number of ways, including
through the front panel keypad, with the optional Crate Foot Controller, or via MIDI.

Within the pages of this Operating Guide you will find all sorts of per­tinent, useful and sometimes technical information which we at Crate
felt you ought to have. Please indulge us a bit and take the time to
actually read through this Guide at some point. Until then, for those
of you who just can’t wait to plug in and go, we offer you:

((ppaaggee 11))

There you’ll find just enough information to get you started. If you run
into any situation that isn’t covered in the Quick Start section, you
might have to – guitar gods forbid – read this guide first.

We at Crate thank you for choosing the DXJ112 Digital Guitar Amplifier!

Important Safeguards and Precautions:

All Crate products are designed for continuous safe operation, as long as common sense is used and steps are taken to help avoid cer­tain problems. Abiding by the following rules can help prevent damage to your amplifier, yourself and others.

• The amplifier is equipped with a three-pronged AC power cord. To reduce the risk of electrical shock, NEVER remove or otherwise attempt to defeat the ground
pin of the power cord.

• Connect the amplifier ONLYto a properly grounded AC outlet of the proper voltage for your amp.

• Avoid sudden temperature extremes, rain and moisture. Also, avoid sudden and intense impact. (If the unit has been subjected to any of the preceding abus-

es, have it looked at by an authorized service center.)

• NEVER set the amplifier on a support that might give out under its weight.

• Always keep the total speaker impedance at or above the rated load.

• Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the amplifier. Wipe it with a slightly dampened, lint-free cloth to remove dirt and film.

• Do not use the amplifier if it has sustained damage to the chassis, controls, or power cord. Refer the unit to an authorized service center for inspection.

• Amplifiers capable of producing high volume levels are also capable of inflicting permanent hearing loss or damage, if the exposure to such levels is prolonged.

Such damage is progressive and irreversible! Consider using quality hearing protection devices.

The Input Jacks:

The DXJ112 has two input jacks – High In (straight) and Low In (padded) – to accommodate a
wide range of pickups and playing styles. The jack you use depends on your type of pickup(s) and
the sounds you’re after.

For example, most players will plug their guitars into the High In jack. These players include those
with “normal output” pickups and some players with “hot” pickups who are looking for some
added distortion.

Some players will choose the Low In jack. These players are mostly those with “hot”/active pick­ups who want a cleaner sound, with more headroom for the Gain control.

When nothing is plugged into either input jack, the DXJ112 mutes its internal speaker.

The Stereo Line Out/In Jacks:

The DXJ112 has a Stereo Line In and Line Out jack (rear panel), for use as a stereo effects loop, or
to send a preamplified signal to an external stereo power amp.

To use an effects loop, connect the Line Out jack to the input of the effects device, then connect
the output of the device to the Line In jack.

To send a preamplified signal, connect a stereo signal cable from the Line Out jack to the input of
the stereo power amplifier.

The jacks are wired as follows: TIP = left channel, RING = right channel, SLEEVE = ground.

The Line Out jack signal is post master, post eq, and post effects.

•If you want to connect a DXJ112 to
another guitar amplifier for stereo
sound, you’ll need to make a custom
patch cable like the one shown to the
right. Use this cable to connect your
DXJ112 Line Out jack to the Line In
jack of the second guitar amp AND
the DXJ112 Line In jack.

You can store and recall a total of 128 presets when using a MIDI footswitch. These presets are
accessed by MIDI program numbers 0 through 127. (Also, see the MIDI Implementation Chart,
Appendix B, page 27.)

WARNING: The MIDI In/Crate Foot Controller button must be in the OUT position

for MIDI operation. (The IN position applies power to the Crate Foot Controller

which could cause damage to a different type of MIDI footswitch.)

UUssiinngg tthhee CCrraattee FFoooott CCoonnttrroolllleerr::

The optional Crate Foot Controller (model DXFC) lets you store and recall a total of 128 presets and
allows foot control of the tap tempo function. The controller gets its power straight from the amplifier,
so no external power source or batteries are needed!

Plug the connecting cable into the MIDI In/Foot Switch jack and set the MIDI In/Crate Foot Controller
button to the IN (foot controller) position. This applies the power needed for the Crate Foot Controller.

(See the Foot Controller’s User’s Guide for more complete information – when you get one!)

TThhee MMIIDDII TThhrruu//OOuutt JJaacckk::

The MIDI Out/Thru jack lets you control other MIDI devices with the Foot Controller. Connect this
jack to the MIDI In jack of the device you wish to control.

The MIDI Thru works with either a standard MIDI input (footswitch) or with the Crate Foot Controller
plugged into the MIDI In jack, since the Crate Foot Controller sends standard MIDI messages.

TThhee SStteerreeoo HHeeaaddpphhoonneess JJaacckk::

Plug a pair of stereo headphones into this jack, for private listening. The internal speaker is discon­nected when headphones are used. The headphones signal is speaker compensated for a realistic
sound even without a guitar speaker cabinet. Since this amp can play LOUD, be careful when using
headphones – prolonged exposure to those high dB levels can wreak havoc on your eardrums! (See

warnings and OSHA regulations about noise exposure levels on page ii.)

The Headphones Jack can also be used as a stereo direct out for recording.

DXJ112 Digital Guitar Amplifier

The DXJ112 is actually 16 different amplifiers in one! The software inside the DXJ112 convinces
the signal that it’s going through the electronic components of the selected amplifier, giving it all of
the characteristics of that amp! (More or less – it’s really a lot more technical than that, but you get
the picture. For a slightly more technical description, see Appendix A on page 25.)

Use the amp model selector knob to choose which amp model you want. The chart on the fol­lowing page lists the name we gave the amp model, the “make and model” of the amp we emulat­ed, and a brief description of the original amp.

to fame

Black Face Fender Deluxe Reverb AA763 The classic tube amp – one of the first amps with reverb, a mid-60’s sta-

ple to the rock and roll diet (considered by some to be one of the best
amps ever made)

Large Tweed Fender Bassman 5F6-A Originally designed for bass, favored by guitarists for its big sound – a late

50’s classic

60s Era UK Marshall 1959 The renowned “brown sound” – a softer, smoother Marshall than the

more modern creations

70s Era UK Marshall JCM 800 The sound of ROCK! – loud and powerful with a definitive edge

Each DXJ112 amp model has its own specifications and placement in the signal chain for its Gain,
Bass, Mid, and Treble. (In other words, the controls affect the signal the same in the amp model as
they do on the original amplifier.)

Use the Preset Parameter controls (Gain, Bass, Mid, Treble, Channel Level) to change the gain, tone,
and volume of the selected amp model. The chart on the following page lists the model name and
the specifications/placement for the Gain and EQ controls.

(TIP:) When using the Acoustic or Clean amp models, set the Channel Level to maximum
and use the Gain control for your volume level.

Each of the digital effects has one or more parameters you can change by using the Effects
Adjust control. All of the effects (except the compressor and the Touch Wah) can also be
changed by using the Tap function – either through the Keypad, or with the Crate Foot
Controller. The chart on the following page lists the effects along with the parameter(s) affected
by the Effects Adjust knob and the Tap button.

NOTE: On multi-effects, modulation speed and echo time are set simultaneously by the Tap button.

To bypass the digital effects, turn the Effect Adjust control fully counter-clockwise and select the
Bypass/Comp effect. (Notice the chart on page 18: There is no compression with the Effect Adjust
knob full counter-clockwise, therefore no effects are applied to the signal – thus, “effects bypass.”)

TTHHEE KKEEYYPPAADD

The DXJ112’s Keypad is used to recall and save presets as described below.

Recalling the Presets:

There are ten presets accessible from the keypad, in two banks of five per bank: with the A/B but­ton off (not lit), the numbered buttons to recall presets 1–5 (bank A); with the A/B button lit, the
buttons recall presets 6–10 (bank B). Each preset stores its own set of parameters (amp selection,
tones, level, effect, etc.). Once a preset is selected, turning a knob will change that knob’s setting
only – the other settings will electronically remain at their virtual positions until you change them.

“What’s a virtual position?” (Good Question!) It’s the setting that the amp remembers
for each knob when a preset is stored. Example: Let’s say the Gain control was at
10:00 when preset 1 was saved, then changed to the 3:00 position. The actual set­ting for the knob is 3:00. Recall preset 1 and even though the knob is physically point­ing to 3:00, the amp acts as if the knob were set to the 10:00 position – because
that’s the virtual position for that knob in preset 1. (Got it?)

Saving New Presets:

Once you get a sound setting you want to keep, assigning it to a preset button is easy: press and
hold the desired button (1–5, bank A; 6–10, bank B) until the keypad flashes (about 3 seconds).
The settings are now stored at that preset location.

(NOTE: The charts on pages 23 and 24 give you a place to record the settings for your presets.
Presets 1–10 are accessible through the keypad, presets 11–128 are accessible by use of the
optional Crate Footswitch Controller)

The Tap Button:

The Tap button lets you match the delay time and modulation speeds of the effects (except for
the compressor, which has no delay or modulation) to the tempo of the piece you’re playing. Just
tap your finger in time to the beat, on the Tap button of course, and the selected effect will change
accordingly. The Tap button flashes in time with its tempo.

(NOTE: The chart on page 18 lists specifically what the Tap button controls for each effect setting.)

The Manual (“MAN”) Button:

When you call up a preset, the preset remembers how the controls were set when the preset was
stored (their virtual positions), and basically ignores their current settings. Pressing the Manual but­ton makes the amp pay attention to the actual positions of the controls and applies their settings to
the sound.

AAnnootthheerr ffuunnccttiioonn ooff tthhee MMaannuuaall bbuuttttoonn::

• Restoring Factory Default Presets: To restore the presets to their original factory settings, press

and hold the Manual button and button #5 until the keypad flashes (about 3 seconds). Then turn
the amp off, wait five seconds, and turn it back on. The presets are now restored to the original
factory settings.

WARNING! Restoring the factory presets wipes out any and all changes

you’ve made and any new presets you’ve stored, so use it carefully.

Other things you should know about the illuminated buttons:

• As soon as you change any of the controls (except for the Master volume), the preset button
starts flashing. That’s its way of saying “Hey! You’ve changed me!” A tap on the flashing button
returns the preset to its original parameters – and makes the button stop flashing. Of course,
you can save the changes, as described under “Saving New Presets” on the facing page.

• When you change banks, the preset button will go out as soon as you press the A/B button,
but no other changes are made until another numbered button is pressed. In other words,
although there is a visual change, the amp won’t store the preset or switch to a different one
(depending on how long you press the numbered button) until you want it to.

Designer’s Note: Amplifier Modeling:

Building an amplifier model is really not much different than building an actual amplifier. With an
actual amplifier you start with components like tubes, transformers, resistors, capacitors, and a
speaker, and put them together to create an amplifier. With a virtual amplifier you start with virtual
components and put them together to create an amplifier model.

It all starts with what many consider to be the "magic" in the sound of many vintage amplifiers: the
vacuum tube. We created a tube model flexible enough to emulate different types of vacuum
tubes, from preamp tubes such as the 12AX7 to power amp tubes like the 6L6 and the EL84.

Next, we constructed models to duplicate the filtering and equalization that takes place between
the gain stages of an amplifier. These equalization models are adaptable to precisely emulate the
frequency characteristics of a specific amplifier’s controls. We even created models for the output
transformer and power supply sag characteristics.

After extensive research, we discovered that there's really no magic in the tube itself. Much of the
tube amplifier sound is a result of not just the tube, but the way the tube interacts with the other
components in the amplifier. We created our tube models to interact with the other components
in our virtual amplifiers, just like the real thing.

After we developed our component models, we put them together to create our virtual amplifiers.
We sound tested our amplifier models extensively to ensure that they remained true to the sound
and feel of the original amplifier. Although we may have taken the magic out of the tube, we
wanted to keep the magic of the tube sound.

The diagrams on the following page show the signal chain of the DXJ112 amplifier.

• The digital signal path, which is the path the signal takes inside the digital signal processor.

• A typical Amplifier Model. This simplified block diagram shows the digital signal path through the
many virtual components of the Studio Tweed Amplifier Model. Note that the Fender Deluxe
did not have a Mid or Bass control, so we added these controls post-gain.
