INSTRUMENT & GUITAR AMP
Plug your instrument into the Instrument Input jack located on the front panel.
Connect a cable from your amp input to the Line Out Left Output jack. Turn the
SGX LT on first and then turn on your guitar amp. TURN DOWN THE LEVEL OF YOUR AMP
before you play! Adjust your front panel levels to your taste. Adjust your
amplifier levels accordingly.
INSTRUMENT & SGX LT in the EFFECTS LOOP of an AMP
Plug your instrument into your amp as normal. Connect a cable from the SGX LT's
Instrument Input to the amplifiers effect send. Now connect another cable from
the effects return of your amp to the Left Output of the SGX LT. Turn the SGX LT
on first then turn on your power amp. Adjust your playing level while the effects
loop is out of the chain. Center all your front panel knobs. Engage the effects
loop and set the input level to the SGX LT with the effect send control of the
amp so the signal LED is lit all the time (with signal present of course). Set
your front panel controls as you like.

INSTALLATION
The SGX LT may be used in a variety of setups including: mixing consoles with
effect send and return facilities, straight into guitar or power amps, and in the
effects loop of an amplifier. Self contained in an all steel single high 19" rack
mount case, the SGX LT is designed for continuous professional use. For touring
rack applications, care should be taken to support the units rear if the rack
might be subjected to mechanical shock like dropping. NOTE: The front panel may
bend if no rear support is provided. Mounting location is not critical, but for
greater reliability we recommend that you not place the unit on top of power
amps, tube equipment, or other sources of heat.
POWER
This device is AC powered via a standard 3 conductor grounded power cable. Plug
into any standard AC receptacle. We recommend the use of a surge protector to
decrease the chance of equipment damage due to voltage surges or spikes on the
line. For your own safety as well as the safety of others, do not remove the
ground pin of the cable. Refer to the rear panel or the specifications for proper
operating voltages.
CONNECTIONS
Audio connections to the SGX LT are made at the front and rear of the unit via
professional 1/4" phone jacks. The MIDI connection is accomplished via a five pin
"DIN" jack on the rear panel.
INPUTS:
There are two mono inputs available in the SGX LT. You can use both input jacks
at the same time. However, the preamp output will be summed with the Line In
input and then the combined inputs will be sent to the digital processor.
INSTRUMENT INPUT
The Instrument Input on the front panel is a single ended (unbalanced)
configuration with an input impedance of 470K ohms. This input is a direct input
to the SGX LT's solid state preamp. Plug in all types of instruments to this
jack. You may also plug "line" level devices into this input.
LINE INPUT
The Line Input jack on the rear panel is a direct input to the digital processor.
This input is a single ended (unbalanced) configuration with an input impedance
of 1M ohm. The nominal operating level for this input is (-)10dB. Hook up high
output instruments, recording devices, other outboard signal processors, and
effects loop sends to this input.
OUTPUT
The LEFT and RIGHT outputs are single ended (unbalanced) with an impedance of
1.5K ohms, and can provide a stereo or mono output. When both outputs are used
with one or both of the inputs, a stereo image is produced. If you do not want
both output signals combined (such as only one delay time required), plug a dummy
plug into the unused output. If you are only using one output use the Left
output.
4

HEADPHONE OUTPUT
A headphone output is located on the rear panel. The headphone output is a
standard 1/4" stereo jack. Any headphones may be used with this jack. Use the
Output slider to set the final output level for your headphones.
MIDI IN
This jack receives the MIDI program change messages. It enables you to change the
presets of the SGX LT from an external source such as an ART X-11 or X-15, a
computer equipped with MIDI ports and associated software or a sequencer.
BYPASS JACK
The Bypass/Inc jack may be programmed to either bypass the SGX LT or access the
Increment Preset Mode. A footswitch and any two conductor cable is intended to be
used with this jack. A momentary (normally open) switch should be used. If the
jack is programmed for the bypass feature, each time the footswitch is activated,
(hot connected to ground) the SGX LT will be bypassed. The default setting for
the Remote Jack is Bypass Mode.
This jack may also be programmed to increment up through a user selected set of
presets. The maximum number of presets you may select for this function is one
hundred twenty-eight. Only one hundred twenty-eight presets can be accesed at one
time because that is the maximum amount of presets allowed for by the MIDI
standard.
Example four and five in Appendix B show how to program the REMOTE jack for
BYPASS or INCREMENT PRESET.
REMOTE JACK(CHANNEL SELECT)
The REMOTE jack switches the preamp between the clean and dirt channel. A
footswitch and any two conductor cable is intended to be used with this jack. A
momentary (normally open) switch should be used. Each time the footswitch is
activated, (hot connected to ground) the channel switches.
CONTROLS AND OPERATION
PREAMP CONTROLS/CLEAN CHANNEL
CLEAN GAIN
To adjust the input gain of the clean channel use the Clean Gain control. The
control range of input level is 0 to 11. When set at zero, no signal is allowed
to enter the preamp so you will have no output. At eleven, maximum signal is
achieved. Set this control so your Signal LED is lit while you're playing and the
Clip LED lights with sharp attacks. Be careful not to set this control to high
because you might clip the digital effects. Monitor the digital section by moving
the Mix slider fully to the right and listen to the output. After you have set
your input gain, set your Mix control.
CLEAN CONTOUR
5

Use this control to set low and high end frequency contours. With the control set
left of 12 o'clock, low frequencies are boosted and higher frequencies are cut.
At 12 o'clock, the control is "flat", no boost or cut to anything. To the right
of 12 o'clock, high frequencies are boosted and low frequencies are cut.
Frequency range is from 130Hz to 1.3KHz low to high.
6

PREAMP CONTROLS/DIRT CHANNEL
DIRT DRIVE
To adjust the input drive of the dirt channel use the Dirt Drive control. The
control range of input drive is 0 to 11. When set at zero, no signal is allowed
to enter the dirt circuits so you will have no output. A little bit above zero
will provide a warm overdrive sound. As you increase the control, distortion
drive increases. At eleven, maximum signal and crunch is achieved. Set this
control to get the right amount of overdrive or distortion in the dirt channel.
THRUST
Thrust is the bass frequency cut and boost filter control. A (+)12 dB boost in
gain and a (-)12dB cut in gain are the maximum ranges. At zero, (12 o'clock) the
filter is flat. the center frequency (the actual filter frequency) is 180 HZ.
MID VOICING
To control your midrange tone use the Mid Voicing control. A (+)12 dB boost in
gain and a (-)12dB cut in gain are the maximum ranges. At zero, (12 o'clock) the
filter is flat. the center frequency (the actual filter frequency) is 850Hz.
EDGE
High end frequencies are controlled with the Edge control. A (+)12 dB boost in
gain and a (-)12dB cut in gain are the maximum ranges. At zero, (12 o'clock) the
filter is flat. the center frequency (the actual filter frequency) is 4.00Khz.
DISTORTION LEVEL
The Distortion Level control sets the final level of the Dirt Channel. Set this
control so your Signal LED is lit while you're playing and the Clip LED lights
with sharp attacks. Be careful not to set this control to high because you might
clip the digital effects. Monitor the digital section by moving the Mix slider
fully to the right and listen to the output. After you have set your input gain,
set your Mix control.
TELLTALES
OVERDRIVE ACTIVE INDICATOR
When this LED is on, it indicates the Dirt channel is active.
SEVEN SEGMENT DISPLAY
The Seven Segment Display keeps you constantly informed of your Preset or MIDI
program number. Preset numbers are displayed from 01 to 99 and then, for presets
over 99 a letter and number. Refer to the preset list at rear of this manual for
preset "numbers". Bypass is indicated by two horizontal bars.
INPUT LEVEL INDICATORS
Front panel LED indicators show the status of the input signal level as it enters
the digital processor. The Signal LED indicates the presense of audio signal. If
the CLIP LED is lit, it indicates you are clipping the digital processor. For
7

maximum dynamic range the Signal LED should be on most of the time with the CLIP
LED briefly flashing on transients only.
8

CONTROL BUTTONS
CHANNEL SELECT/AUTO STORE
Press this button to manually switch between the clean and dirt channel. When you
change the preset's clean/dirt status with this button, the SGX LT remembers the
last state the preamp was in. So, if the Clean channel was active in the preset
when you first used it, and then you switched to the Dirt channel, the next time
you call up that preset, the Dirt channel will be active. We call this "Auto
Store" because the SGX LT remebers the last state of the preamp section.
PRESET ¿À
The Preset UP and DOWN buttons (¿, À), shown as purple triangles facing up and
down on the front panel are used to select PRESETs. Holding either button in will
step you through all the Presetss at a moderate rate. You can step at a much
quicker rate by first pressing and holding in the button indicating the direction
you want to go, simultaneously press the other button. As long as both are
pressed the presets will increment by tens rather than one at a time.
BYPASS
Pressing the BYPASS button kills the effects signal in the mix. The display will
show [- -] in the preset window. Pressing BYPASS again returns the preset to
active status.
NOTE: If the mix control is fully right (effect only), there will be no audio
signal at the output.
Another way to bypass the unit is to program the REMOTE jack on the rear panel
for BYPASS mode and use any footswitch and guitar cable.
MIDI
Pressing the MIDI button allows you to change two things. One, the MIDI channel
the SGX LT receives information on and two, access to the MIDI Program Table.
You can set the SGX LT to receive MIDI information on one of 16 or all channels.
The default setting is to receive info on all 16 channels. This is known as Omni
Mode and is displayed as [Al.] in the Program Display window. To change the
channel, refer to the example in Appendix B.
Presets may be accessed at the front panel or remotely via MIDI. When the SGX LT
receives a MIDI PROGRAM number, it recalls a PRESET. If the SGX LT was in BYPASS,
it will become active. The PRESET recalled is determined by a table that equates
MIDI PROGRAM numbers to PRESET numbers. This table is called the MIDI PROGRAM
TABLE (MPT). SGX LT's are shipped from the factory so that the MIDI PROGRAM
numbers equal the PRESET numbers (MIDI program 0 = Preset 00). You can reassign
any Preset number to any MIDI Program number. When you first power up your SGX
LT, the first 128 presets are the default MIDI presets. You cannot access all the
presets in the SGX LT at one time with MIDI. It's not our fault, MIDI only allows
for a maximum number of 128 presets.
So, to access the presets above location 128, some simple programming of your SGX
LT is required. The ability to reassign Preset numbers makes it much more
practical when using MIDI in both simple and complex setups. To change the MPT,
read the next section and refer to the examples in Appendix B. We will refer to
9

the MIDI PROGRAM number as the MIDI number. Any changes made to the MPT will be
retained during power down by battery backup.
10

MPT EDIT MODE
The MPT may be edited from the front panel either alone or with a keyboard or
MIDI controller that sends MIDI program change numbers.
To enter MPT edit mode, momentarily press the MIDI and BYPASS buttons
simultaneously (Pressing MIDI first then BYPASS will have no effect on the
current BYPASS state, pressing BYPASS first toggles the current BYPASS state).
Press MIDI and BYPASS again to stop editing the MPT and return to normal front
panel operation.
When MPT edit mode is entered, the LEFT decimal point will be blinking indicating
that the display is showing a MIDI number. If BYPASS is then pressed, the RIGHT
decimal point will blink and the display will be showing a PRESET. If MIDI is
pressed the left decimal point will blink again indicating the return to the MIDI
number in the display. Use the UP/DOWN buttons to change the numbers in the
display. When a MIDI number message is received, the corresponding PRESET number
in the table will be recalled.

NOTES:
1) Multiple MIDI numbers may have the same PRESET number assigned to them.
2) When you pass [9.9] a letter and a number appear. [A.0] is equal to 100, [b.0]
is equal to 110, [C.0] is equal to 120. [C.7] is the last "number" and is equal
to 127.
MIX CONTROL
The MIX slider controls the amount of dry and proccessed signal mixed together.
When the control is fully towards the left (0%), only the dry signal is heard at
the output(s). As the slider is moved to the right, processed signal is mixed in.
At the center detent position a fifty/fifty mix is achieved. When the slider is
full right (100%), only processed signal is heard at the output(s).
MISCELLANEOUS
PRESETS
Up to three different effects may be found in each of the SGX LT's presets. The
presets reflect various combinations of effects as well as singular effects.
Presets are arranged in specific application groups to make it a little easier
for you to find the right sound. These include reverb, chorusing, flanging and
delay groups. Presets devoted to natural reverberation, cover a wide range from
extremely short 0.2 second to 23 second decays. Predelay, high frequency damping,
position, reverb density and reverb level are set for the most optimum sound in
each preset.
Within each section of reverb are a variety of related effects, not just bigger
or smaller versions of the same. Some of these effects would normally require
multiple pieces of equipment to create. A variety of algorithms each with its own
11

unique characteristics are used to simulate a wide range of environments. Within
the other presets are Gated Reverb effects, Reverse Reverb effects, Gated effects
with regenerated delays, Flanging effects, Panning, Chorus effects, straight Echo
effects, Delay based effects such as chorusing and flanging are combined with
reverb and delay to create special effects reverb sounds. A list of all the
presets can be found in the back of this manual.
BATTERY BACKUP
When power is terminated to the SGX LT, the edited MPT is retained via battery
backed up memory. This as well as the last PRESET and the MIDI CHANNEL will be
active when the unit is next powered up. Memory retention is expected to last
four years. If you encounter memory loss, contact our customer service
department.
BYPASS PRESET
PRESET Y9 is a non-sound preset. It is used as a MIDI bypass preset. Use Y9 when
you don't want any effect to be in the signal chain for a particular keyboard
preset. The MIDI PROGRAM NUMBER assigned to Y9 is (127) or [C.7] as it appears in
the display.
SOFTWARE LEVEL
On power up, the SGX LT momentarily indicates its operating software level in the
display. The software controls the SGX LT's functions as well as its sounds.
USER REGISTRATION
Be sure to fill out the USER REGISTRATION CARD in this manual and send it in to
our Customer Service Department. This will ensure you of being notified of
information regarding the SGX LT. Please don't forget to write in your serial
number.
FACTORY RESET
Resetting the MPT
It is very unlikely you would want to reset the SGX LT's MPT. Normally you should
just re-edit the MPT for new values.
Should you wish to set all the values back to their initial state, power down the
unit. Hold in the Up/Down buttons (¿,À) and while holding them in, power up the
SGX LT.
Customer Service
You may contact ART's Customer Service Department between the hours of 9:00 AM
and 4:00 PM Eastern Time Monday through Friday. The Customer Service Department
will answer technical questions about ART products and provide information
concerning service.

APPENDIX A
MISCELLANEOUS NOTES
The presets found in the SGX LT cover a wide range of diversified reverb sounds
and special effects. The following notes provide a starting point for you to use
these presets to add that special if not essential sound to your own individual
sound.
Though it is not mandatory it is strongly suggested you utilize the stereo
capabilities of the SGX LT. Many of the reverb patches and delay effects rely
heavily on stereo image or right left characteristics to achieve the brilliance
and realism found in today's and yesterday's sound!
The most important application of all is to EXPERIMENT! Remember, there are over
250 effect combinations at your fingertips. What may be used for normal desirable
effects can also be applied to create entirely new and different sounds. Your own
ideas and expressions may be realized with just a few pushes of a button. Go
ahead, have some FUN!
The reverb presets come in a variety of ways, shapes and sounds. Emphasis is
placed on different room types, image, position of the perceived sound and the
brightness or dullness of the sound.
The presets reflect a range of reverb effects with different combinations of
these characteristics. Don't be afraid to cycle through a number of presets with
the mix control fully wet so you can hear the actual image position or character
of the preset. Above all don't be afraid to experiment.
APPENDIX B
EXAMPLES
EXAMPLE 1:
Editing the MPT with the SGX LT front panel controls.
In this example, we will edit the MPT so when MIDI numbers 0 and 1 are received,
presets 64 and A1 will be recalled. It is assumed the SGX LT's MPT has not been
edited.
Press and hold MIDI, then BYPASS buttons, release both.
The display will show [0.0] with the decimal point blinking indicating that you
are in MPT edit mode, this left decimal point means that the MIDI PROGRAM number
is in the display.
*-Press and release BYPASS. The display shows [00.] indicating that MIDI number 0
recalls PRESET 0.
*-Press and hold UP until [64.] appears in the display. Now MIDI number 0 will
recall PRESET 64.
*-Press and release MIDI. The display shows [0.0]
*-Press and release UP. The display shows [0.1]
*-Press and release BYPASS. The display shows [01.] indicating that MIDI number 1
recalls PRESET 2.
*-Press and hold UP until [A1.] appears in the display. Now MIDI number 1 will
recall PRESET A1.
13

*-Press MIDI and BYPASS to exit MPT edit mode. The display shows [A1] indicating
the last PRESET referenced is the current PRESET selected.
During the above example, anytime a MIDI number is changed or PRESET number is
changed, the SGX LT recalls the corresponding PRESET. This allows you to listen
to the PRESETs while the MPT is edited.
EXAMPLE 2:
Editing the MPT with a keyboard or external controller.
When used with a keyboard or other device such as the ART X-11 or X-15 ULTAFOOT
capable of sending MIDI PROGRAM CHANGE messages, MPT editing is simplified. We
will edit the MPT so when MIDI numbers 2 and 3, are received, presets 55 and Y4
will be recalled. It is assumed that the SGX LT has not had its MPT edited.
The keyboard or MIDI controller MIDI OUT must be connected to the SGX LT MIDI IN
jack. The MIDI on the SGX LT must be set to the same channel the keyboard will be
sending messages on, or the SGX LT MIDI must be set to [AL.] for OMNI mode.
Press and hold MIDI, then press BYPASS. The display will show [0.0] with the
decimal point blinking indicating that you are in MPT edit mode, this left
decimal point means that the MIDI PROGRAM number being displayed.
Select a patch on the keyboard so [0.2] appears in the display. This may not be
sound 2 or patch 2 on the keyboard. Different companies number their presets in a
variety of ways. The patch causing [0.2] to appear in the display is usually the
first or second patch of the lowest numbered bank if the keyboard or controller
has banks of patches.
*-Press and release BYPASS. The display shows [02.] to indicating MIDI number 2
recalls PRESET 2.
*-Press and hold UP until [55.] appears in the display. Now MIDI number 2 will
recall PRESET 55.
-To program the rest of the entries, you do not need to switch back to the MIDI
number. You can let the unit remain showing the PRESET number. (When you select
your keyboard or foot controller preset, you automatically recall the existing
SGX LT preset.)
*-Select the next patch on the keyboard. The display will show [03.] to indicate
that it recalls PRESET 4.
*-Press and hold the UP button until [Y4.] appears in the display. Now the last
patch number activated will recall PRESET Y4.
By using this method of editing, you select the desired patch on the keyboard or
controller, and then select the desired PRESET on the SGX LT for that sound. You
can do this while you are listening to the SGX LT. Exit MPT mode as in the
previous example.
In the previous examples four of the MPT entries were edited, however, you may
edit the entire MPT if desired. If you do not have access to a MIDI controller
and you wish to change between PRESETs easily, you may want to edit the MPT for
incrementing through a sequence of PRESETs. Example three illustrates how this is
ne.do
EXAMPLE 3
Setting up a preset sequence including the BYPASS (Y9) preset.
14

If you need to change between presets quickly without scanning, this procedure
will be to your advantage. As in the other examples, editing the MPT is the key.
In this example we will edit the MPT to sequence through ten PRESETS. These
PRESETS are in the order: 26,J4,F2,69,E2,U2,69,Y9,82,26. Notice that we repeated
some presets and included the BYPASS preset (Y1). Remember, you can assign any
preset to a MIDI number including using a preset at multiple locations. Using the
BYPASS preset enables you to select no effect without having to bypass the unit
from the front panel and then continuing on with an effect preset next in the
chain.
*-Enter the MPT edit mode.
*-With the left decimal point blinking, use the up/down buttons to get a display
of [1.0].
*-Press the BYPASS button, the decimal point now blinks on the right side.
*-Use the up button to select PRESET 26. The display will be [26.].
*-Press the MIDI button and set the display for [1.1].
*-Press the BYPASS button and set the display for [J4.].
*-Continue this way until all the PRESETs are entered the last being 26.
*-DO NOT LEAVE THE MPT EDIT MODE
*-Press the MIDI button and go to [1.0]. As you increment up, you will recall the
sequence of presets just entered.
This way of arranging presets is helpful when you have presets you need to get to
quickly. Instead of scanning up and down through multitudes of presets, you need
only scan through the ones you use the most. Make a table of the MIDI number and
assigned Preset for quick reference since you can only view the MIDI program
number.
NOTE: Start your sequence at MIDI program number ten or twenty. This will leave
you room for programming presets for the Increment Preset feature.
EXAMPLE 4
Changing the MIDI channel
To select a specific MIDI channel, press the MIDI button and use the up/down
buttons to select the desired channel. The right decimal point will be on
whenever the display is showing MIDI. The channel number is held in memory when
the unit is turned off.
INCREMENT PRESET
Increment Preset Mode (IP) allows you to program the REMOTE jack on the rear
panel so that you may use a footswitch to increment through a desired set of
presets.
Example four describes how to set IP to sequence through five presets. A maximum
of one hundred twenty-eight presets may be sequenced. You must always start at
MIDI Program number one when using IP for sequencing.
Example five shows how to program the REMOTE jack for normal bypass operation.
IP is accessed through the MIDI Program Table. To enter the MPT edit mode, press
and hold the MIDI, then BYPASS buttons, release both. The display will show some
number with the left decimal point blinking. Increment up (use the RAPID ACCESS
mode!) until the display reads [l.P]. This indicates Increment Preset. You are
now ready to program. Press the BYPASS button, the decimal point is now blinking
15

on the right. Set this number for the last entry number desired. In this example
we'll set the number to [04.] for the sequence of FIVE presets desired. If you
set the number to [00.], you will have programmed the jack for use as a bypass
jack. Now press the MIDI button and increment down to the desired MIDI Program
Number.
Note, when you pass [9.9] a letter and a number appear. [A.0] is equal to 100,
[b.0] is equal to 110, [C.0] is equal to 120. [C.7] is the last "number" and is
equal to 127. Press the BYPASS button and set the display for the desired PRESET
number.
Program the sequence to be 64, A1, 55, Y4 and H1. If you have gone through
Example 1, the first four presets have been set all ready. All you need to do is
add the fifth preset.
After programming is completed press and hold the MIDI button then the BYPASS
button to exit. Now, each time the footswitch is activated, you will change
presets in the selected sequence. The sequence of presets will wrap-around to the
beginning, at the end of the sequence.
EXAMPLE 5
Setting up five presets for Increment Preset Mode. Use preset numbers 64, A1, 55,
44 and H1.
*-Enter the MPT edit mode
*-With the left decimal point blinking, increment up (use RAPID ACCESS mode)
until the display reads [l.P].
*-Press the BYPASS button
*-Adjust the display to read [04.].
*-Press the MIDI button
*-Increment down (use HYPERSPEED) until the display reads [0.0].
*-Press the BYPASS button and set the display to read [64.].
*-Press the MIDI button and set the display for [0.1].
*-Press the BYPASS button and set the display to read [A1.].
*-Continue this until you reach and program [0.4] to be [H1.].
*-Exit MPT edit mode
You have just programed the SGX LT to sequence through five PRESETS when the
REMOTE jack is activated.
EXAMPLE 6
Programming the REMOTE jack for the BYPASS function.
*-Enter MPT edit mode.
*-Increment up until the display reads [l.P].
*-Press the BYPASS button.
*-Set the display to read [00.].
*-Exit MPT edit mode.
The FOOTSWITCH jack can now be used as an external BYPASS jack.
