Hooking Up and Supplying Power
DO NOT APPLY POWER TO THE TEC8 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 TEC8 output 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 TEC8.
3) Power up the TEC8 by connecting the supplied AC adapter between the TEC8 and a power outlet.
4) Play your instrument and watch the Clip LED on the TEC8 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 only flicker on the loudest pas­sages.
5) Set the Output level as desired.
The TEC8, 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 get the best pos­sible performance out of your TEC8 while avoiding damage:
4
• Always make sure you have a "clean" power source for connecting to the TEC8. This means that the AC power line you connect to the TEC8 should be as free from voltage fluctuations and RF interference as possi­ble.
• Use a good quality spike / surge suppressor. 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.
• 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 running them parallel to one another

SECTION 2 - PROGRAMMING THE TEC8
Navigating The TEC8
The TEC8 is designed to be both easy to program and flexible. The struc­ture of a TEC8 Program is logical and doesn't require a lot of time to mas­ter.
Selecting Programs in the TEC8:
After you power up, use the Data wheel to scroll through the Programs.
DATA
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 14 effect groupings printed on the front panel of the TEC8. Seven are digital effect groups (delay, reverb, etc.) , six cover the preamp section (compression, distortion, gate, EQ), and one is the Expression Assign group. 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 TEC8. 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 (0 on EQs), indicating that the effect is select­ed but bypassed. (Pressing the Select button again activates 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.)
User LED Indicator
The User LED below the display indicates that the current Program is a User Program in the User bank when lit. When the LED is not lit, the cur­rent Program is a permanent Factory Program in the Factory bank.
Using The Footswitches
The TEC8'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 TEC8, 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:
5
Page 8
Signal Processing
Signal Processing
Signal Processing
1) by pressing the Bank select footswitch followed by footswitch 1, 2, or 3.
2) by turning the Data wheel in Program mode.
To Select Programs using the footswitches:
1) After you power up, the TEC8 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:

NOTE: If a new Program number is not selected within 5 seconds after pressing the Bank select button, the display returns to its previous setting.

Editing Programs
As you become more familiar with the TEC8, you may find that you need to modify certain Programs to better fit your needs. Fortunately, the TEC8 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 63 (which has an Arena reverb, 250 ms Mono Delay, a Tremolo, Noise Gate, EQ, 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 63.
changes to show the number of the Program you selected. The display might look something like this:

2) Press the Delay effect Group button. The Mono Delay Group Status LED begins flashing and the display reads:

DATA
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 31 and 39 in the Mono Delay (not Multi-Delay) effect Group.
4) Use the Data wheel to scroll until the the display reads:
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 TEC8 by pressing the associated Effect Group 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 on the next page.
Expression Pedal Assign
The TEC8 Expression Pedal can be assigned to control 1 of 10 different parameters in a program. This adds a whole new dimension in your sound by letting you make real-time effects changes during performance.

select the Expression Assign Group button and choose one of the numbers that corresponds to the parameter you want the pedal to control. In order for the Expression Pedal to
function with a parameter you have selected, a corre­sponding effect must be active within the program. To
turn on the Wah or Auto Wah, just select either one in the Expression Assign Group.
The following list shows which effects are controlled by each Expression Assignment.

When programs where Volume, Wah, or Auto Wah are selected in Expression Assign, the sound will reflect where the current pedal position is,.otherwise the pedal must be moved in order for the effect to be changed.
Storing Programs
After you have made modifications to a program, you may want to store the changes. The TEC8 lets you store up to 30 Programs in the User mem­ory locations.
Remember, you have to store any changes in a User Program memory location otherwise all your changes will be lost.
To store a Program into a memory location:
User Store
1) Press the Store button. The Store LED begins flashing and the User LED lights (if not lit already).

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
location you selected.
Note: Changes made by the Expression Pedal cannot be stored.
The TEC8's bypass functions are very simple.

The TEC8's Effects
The TEC8’s library of effects is capable of handling virtually any musical sit­uation. The following charts give you relevant information about each module's settings. For example, Noise Gates, Detuners, and Pitch Shifters are not shown because their Module names are relatively self explanatory and are displayed on the front panel. The Fast Swell and Slow Swell Noise Gates have attack times of 500 ms and 1000 ms respectively, which create a volume pedal or bowing type effect.

DISTORTION The TEC8 gives you 8 distortions to choose from, 4 of which
include Cabinet Emulation. Each distortion has 10 settings, giving you plenty of selections when using either an amp or for going direct into a mixer or recording device.

MONO DELAYS
The Mono Delays are arranged in groups of 9. Each delay time has a feedback ratio (number of repeats) and level associated with each number. Here is an example of how each delay time works:
Each Mono Delay time has 9 selections. These selections consist
Mono Delay
1-9 100ms 11-19 200ms 21-29 250ms 31-39 300ms 41-49 350ms 51-59 400ms 61-69 500ms
of 3 different feedbacks (number of repeats) and 3 different lev­els. For example, a Mono 200ms number 15 would have a 200ms delay time, a feedback of 30%, and a level of 30.
Selection fb/lev fb/lev fb/lev
1-3 0%/15 0%/30 0%/50 4-6 30%/15 30%/30 30%/50 7-9 50%/15 50%/30 50%/50
MULTI DELAYS
The Pong and Tap Delays have 2 delay times. The Pong Delays bounce from left to right at a regular interval while the Tap Delays bounce left to right in more of a rhythmic way.
As with the Mono Delays, each Multi Delay time has 9 selections.

These selections consist of 3 different feedbacks (number of repeats) and 3 different levels. For example, a Tap 300/400ms number 63 would have a Tap delay time of 300 and 400 ms, a feedback of 0%, and a level of 50.

Tuner
The TEC8 is equipped with a flexible tuner for on the spot adjustments. There are 3 selectable tuning references as well, Standard, tuning, 1/2 step down tuning, and
Whole step down tuning.
To access the tuner: Press and hold the currently selected program’s
footswitch. The display will read tu. Play a note and the display will show which note is selected. The tuner LED’s will begin to light. If the LEDs to the left of the green In Tune LED are lit, the note shown in the display is flat. If the LEDs to the right are lit, the note is sharp.

To change tuning reference: Press and hold the currently selected program’s footswitch. The display will read tu. Turning the data wheel will select one of 3 references, Standard or A, 1/2 step down or Ab, or Whole step down or g tuning. Now guitars that are tuned a 1/2 or whole step lower than standard will still read the normal letter of the selected string in the display.
Factory Program Reset
Resetting the TEC8 will erase all User programs and restore them to their original Factory settings. Remember, when resetting the TEC8, all previ-
ous User settings will be lost. To reset the TEC8
1- With the power off, press and hold the Low EQ and Mid EQ effect
group buttons.
2- Connect the power while still hold the buttons down. The display will
read:
At this point, all User presets will now be restored to their original Factory settings
