SECTION 1 - GETTING STARTED  
Supplying Power  
The FX7, like any piece of computer hardware, is sensitive to voltage  
drops, spikes, and surges. Interference such as lightning or power  
"brownouts" can seriously, and in extreme cases, permanently damage  
the circuitry inside the unit. Here are a few tips that will help you get  
the best possible performance out of your FX7 while avoiding damage:  
Always make sure you have a "clean" power source for connect-  
ing to the FX7. This means that the AC power line you connect  
to the FX7 should be as free from voltage fluctuations and RF  
interference as possible. In recording environments, "clean"  
power is also important in preventing AC hum or buzz from get-  
ting to tape.  
• Use a good quality spike / surge suppressor (also called a power  
strip). This is an inexpensive solution to all but the most severe  
AC line conditions. A good quality power strip can save you a  
lot of money in repair bills because they prevent large spikes and  
surges from reaching your equipment. Also in this category (but  
more expensive) are rackmount power supplies. Some of these,  
like the DOD 828, have retractable light tubes and RF filtering.  
Although more expensive, AC line conditioners offer the best  
protection from improper line voltages. Line conditioners con-  
stantly monitor the AC line for excessively high or low voltages  
and instantaneously compensate to deliver a consistent voltage  
to the connected equipment.  
Always make sure that your audio lines are as far as possible  
from power cables. This will further prevent noise, hum, and  
stray magnetic fields from entering your signal path. If audio  
and power lines must run close to each other, try to avoid run-  
ning them parallel to one another.

Hooking Up  
DO NOT APPLY POWER TO THE FX7 UNTIL INSTRUCTED.  
1) STEREO: Connect the Left and Right outputs to a pair of guitar  
amplifiers, or the inputs of a mixing console. If you're using guitar  
amps, set the tone controls flat (no boost or cut) and balance the  
levels between them. If you're using a console, pan the FX7 input  
channels hard left and right, and turn down the high frequency  
EQ for best results.  
MONO: Connect the Left output to a guitar amplifier or input of a  
mixing console.  
2) Connect your instrument to the input of the FX7.  
3) OPTIONAL: Connect a volume type or 0/+5v controller pedal to  
the Controller input of the FX7. Make sure the pedal is connected  
before you apply power to the FX7.  
4) Power up the FX7 by connecting the supplied AC adapter  
between the FX7 and a power outlet.  
5) Play your instrument and watch the Clip LED on the FX7 carefully  
as you set the Input knob. Turn up the input level until the Clip  
LED begins to light, and reduce the input level slightly. When the  
Input knob is set properly, the Clip LED should not flicker on the  
loudest passages.  
6) Set the output level as desired.

SECTION 2 - PROGRAMMING THE FX7  
Navigating The FX7  
The FX7 is designed to be both easy to program and flexible. The  
structure of an FX7 Program is logical, and it doesn't require a lot of  
time to master.  
To select Programs in the FX7:  
DATA  
1) After you power up, use the Data wheel to scroll through the  
Programs. As you scroll, the effect group and footswitch LEDs  
turn on and off. These LEDs indicate which effects are used in  
each Program, and which Program in the Bank is selected.  
There are 11 effect groupings printed on the front panel of the FX7.  
Seven are digital effect groups (delay, reverb, etc.) , and four cover the  
preamp section (compression, distortion, gate, EQ). Each group has  
its own LED that indicates the status of each group.  
If the Status LED is lit continuously, an effect in the indicated group is  
active. If the LED is not lit, no effects in the group are active. If the  
LED is flashing, edit mode is active, and effects in the group can be  
selected using the Data wheel.  
Directly below each vertical group are the Effect Selector buttons.  
These buttons allow you to select and/or bypass effects in the FX7.  
The following things happen when you use the Effect Selector buttons:  
• When you select a bypassed effect, its group LED begins flashing  
and the display shows two dashes, indicating that the effect is  
selected but bypassed. (Pressing the Select button again acti-  
vates the effect.)  
• When you select an active effect, its group LED begins flashing  
and the display shows the number of the currently selected  
effect. (Pressing the button again bypasses the effect.)  
When lit, the User LED below the display indicates that the current  
Program is a User Program. When the LED is not lit, the current  
Program is a permanent Factory Program.  
Using The Footswitches  
The FX7's pedalboard consists of four footswitches: the far right  
footswitch is the Bank selector, and the remaining three are Program  
selectors.  
A Bank is a group of three Programs. There are 10 User Banks in the  
FX7, each with 3 Programs for a total of 30 User Programs. There are  
also 30 Factory Programs that can be selected using the Data wheel  
only. User Programs in any of the Banks can be recalled in one of two  
ways:  
by pressing the Bank select footswitch followed by footswitch 1,  
2, or 3.  
by turning the Data wheel in Program mode.  
To select Programs using the footswitches:

BANK  
1) After you power up, the FX7 defaults to Program mode. Select  
a Bank by pressing the Bank selector footswitch. The display  
shows the selected bank number on the left side of the display  
and a dash on the right. The display might look something like  
this:  
2-_

or  
2) Press footswitch 1, 2, or 3. The dash in the display changes to  
show the number of the Program you selected. The display  
might look something like this:  
23  
NOTE: If a new Program number is not selected within 5 seconds  
after pressing the Bank select button, the display returns to its pre-  
vious setting.  
Editing Programs  
As you become more familiar with the FX7, you may find that you  
need to modify certain Programs to better fit your needs. Fortunately,  
the FX7 is flexible enough to give you everything you need without  
being difficult to program.  
The following procedure is an example of how to modify your  
Programs. Suppose that Program 33 (which has a 100 ms mono  
delay, a medium chorus, noise gate, EQ, distortion, and compression)  
sounds close to what you want, but you want a 300 ms delay with low  
feedback instead. Here's how to change it:  
DATA  
1) Use the Data wheel, or the Bank and Program selector  
footswitches to select Program 33.  
2) Press the Delay effect group button. The Delay group Status  
LED begins flashing and the display reads:  
11  
Delay  
3) Look at the front panel Delay groupings to locate the effect you  
want. In this case, you'll see that the 300 ms mono delays can  
be found between 41 and 49 in the Delay (not Multi-Delay)  
Group.  
DATA  
4) Use the Data wheel to scroll until the the display reads:  
4.1  
FX7 owner's manual

s igna l pr oces s ing  
NOTE: When you change the selected Parameter from the stored  
value, a decimal point appears in the bottom right corner of the  
display and the Store LED lights.  
That's it! You can manipulate any effect setting in the FX7 by pressing  
the associated Effect selector button on the front panel and turning  
the Data wheel. The Effect Group buttons also toggle the effects on  
and off with each successive press of the button.  
When you're editing Programs, be sure to pay attention to the flashing  
Status LEDs. This helps you keep track of where you are in the menus.  
IMPORTANT: If you want to store your custom Program so you  
can use it later, follow the procedure below.  
Storing Programs  
The FX7 helps you remember whether or not you've stored the  
Program you're working on by lighting the Store LED under the bot-  
tom right corner of the display when the selected Program has been  
edited.  
Remember that if you change any settings in a Program, you have to  
store the Program into a User memory location. Otherwise, all your  
changes will be lost.  
To store a Program into a memory location:  
1) Press the Store button. The Store LED begins flashing and the  
User LED lights (if not lit already).  
User  
Store  
DATA  
2) Use the Data wheel to select the User location where you want  
to store the Program.  
3) Press the Store button again to store the Program in the loca-  
tion you selected.  
User  
Store  
After the storing procedure is complete, the FX7 returns to normal  
operation at the new Program location.  
NOTE: Factory Programs can't be overwritten. When you modify  
a factory Program and store it in memory, the Program is stored in  
the corresponding number location in the User Program section.  
Bypassing  
The FX7's bypass functions are very simple.  
To bypass individual effects:  
1) From Program mode, decide which effect you want to bypass  
and press its Select button twice. The display reads:  
-.-  
FX7 owner's manual  
10  
 
s igna l pr oces s ing  
Press the effect Select button to toggle the effect in and out of bypass  
mode.  
REMEMBER: The decimal point indicates that the value shown in  
the display is not the stored value.  
To bypass the selected Program:  
1) Press the currently selected Program footswitch on the pedal-  
board. The footswitch's Status LED flashes and the display  
reads:  
bp  
The Program selector footswitch toggles the FX7 in and out of bypass  
mode.  
A Word About Mono Operation  
The FX7 can operate in either stereo or mono. It is important to  
remember that the way you connect your cables to the outputs can  
affect the output mode. Here's a simple way to remember how it  
works:  
• If only one output cable is connected, the FX7 switches to mono  
mode. Otherwise, it operates in stereo.  
Using A Controller With The FX7  
The FX7 is able to respond to most volume pedal outputs or 0/+5v  
controller pedals to control the wah and volume effects in real time.  
To set up the FX7 for this application:  
1) Disconnect the power to the FX7.  
2) Connect the output or the 0/+5v control output of a volume-  
type controller pedal (such as the DOD FX17) to the Volume /  
Wah controller input on the rear panel of the FX7.  
3) Sweep the pedal through its entire range a few times to cali-  
brate the pedal.  
If the Wah is active in any Program, the controller becomes a wah  
pedal. Otherwise, it acts as a volume control.  
REMEMBER: If you want to use a controller pedal with the FX7,  
make sure the pedal is connected to the FX7 before you apply  
power. It is also important to note that the controller's pedal posi-  
tion affects all Programs, even after you change Programs. If a  
Program doesn't sound the way you saved it, check the position of  
the controller pedal.

About the FX7's Effects  
The FX7 has a large library of effects that covers virtually every possible need.  
Because they are so numerous, we have designed the following charts to give  
you as much relevant information as possible while omitting tedious or obvious  
details about each module's setting. For example, Distortions, Tremolos,  
Detuners, and Pitch Shifters are not shown because their Module names are rel-  
atively self explanatory. The Fast Swell and Slow Swell Gates have attack times  
of 500 ms and 1000 ms respectively.
