Valve FX Owner’s Manual SECTION 1 - STARTUP SUPPLYING POWER Line Conditioning - The Valve FX, like any piece of computer hard- ware, 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.
Valve FX Owner’s Manual 5) Display Window - The display window shows all current operating and programming information and is comprised of several parts: the LCD display, the input level meter, the Program number indica- tor, and the Bypass and DSP Clip indicator LEDs. The LCD display shows all Program names, Parameters and Parameter values, and is the communication interface between you and the Valve FX.
1) AC Line Input - This is the power cord receptacle. 2) Foot Controller - This 5-pin DIN plug is for connecting the optional DigiTech Control One foot controller. THIS IS NOT A MIDI PORT. CONNECTING A DEVICE OTHER THAN THE DIGITECH CONTROL ONE FOOT CONTROLLER TO THIS JACK MAY DAMAGE THE DEVICE.
Valve FX Owner’s Manual 5) Outputs - These are the main left and right audio outputs of the Valve FX. Use both outputs when possible since Programs are set up to take advantage of stereo effects. When the Output mode is set to mono, either output can be used.

Page 27
Valve FX Owner’s Manual Now that we better understand all the aspects and properties of Reverb, the Parameters of the Reverb modules are as follows: Reverb On / Off .....Turns the Module on or off. ER Predelay ....Controls the length of time before the early reflections are heard.
Page 28
Valve FX Owner’s Manual RV Predelay ....Controls the amount of time before the first room reverberations are heard. In an actual acoustic space, the amount of reverberation predelay depends largely on the shape and size of the room and the placement of both listener and sound source within the room.
Valve FX Owner’s Manual GATED REVERB Gated reverbs usually include adjustable thresholds to set the point at which the reverberations will be gated (cut off). The Valve FX’s RV DECAY TIME control behaves in somewhat the same way, except that instead of setting the length by level (threshold), the length is set by time (in milliseconds).

Valve FX Owner’s Manual Smpl Triggr Levl....Sets the level at which the audio signal will trigger the sample. Variable from 0 to 100. Smpl Direct Levl....Sets the level of the dry (non-effected) sound. Variable from 1 to 100. Smpl Start Point.....Determines the point at which the sample will begin playing after it has been recorded.
Both notes are constant in pitch, but subtle additions in richness and overtones can be heard. DigiTech’s exclusive Whammy™ allows you to create mind-bending dive bombs and pitch bends with the continuous controller pedal on the optional Control One foot controller or by using MIDI Continuous Controllers.
Valve FX Owner’s Manual Pitch Shft Amount..Sets the interval of semitones between the original note and the pitch shifted note. Variable from -24 to +24 (4 octaves). Pitch Detune....Determines the amount of detuning applied to the shifted note. Variable, in cents, from -100 to +100.
Valve FX Owner’s Manual Whammy Pedal .....The WHAMMY PEDAL Parameter reflects the current setting of the continuous control device used to control the whammy effect. This Parameter can be modified manually using the Valve FX’s stand-alone whammy pedal. As the Parameter is modified, the pitch of the original note will change in intervals according to the setting of the WHAMMY FUNCTION.
