Auditioning Programs

.

The DEP has 16 programs. These programs have been chosen to be the most useful effects
available for a large variety of music styles. To audition the internal effect programs, turn the Pro
-gram Select knob to scroll through each of the 16 presets.

.

A

Adjusting Effects Mix Levels

.

Whether a program contains a single effect or two or three effects, you can adjust the DEP's
[MIX] control to obtain a desirable balance between the original, Uneffected signal and each
effect's output. The [MIX] Knob controls the balance between the input signal and the effects
generated by the DEP. By turning [MIX] to the right allows you to hear more effects; turning it
to the left lets you hear more of the source signal. When hooked up to an instrument setup, such
as a guitar amp, the Mix setting will typically be somewhere in the middle, balancing the effects
with the sound of the source instrument. If the DEP is connected to a mixing console's Aux
Send, the [MIX] control should be set all the way to the right (effects only) so that the balance can

be controlled from the board. When the [MIX] control is turned all the way to the left, you will only
hear the direct signal (effects will be bypassed).

.

a

Editing Programs

.

Any of the internal programs on the DEP may be editing using the [VARIATIONS] knob. The
function of this knob will change depending on the Program selected. For example, it will adjust

reverb decay on a Hall program and lezlie speed on the Rotary program.

.

a

The Adjust knob is always active, so when you change to a new program it will automatic-

ally read the Adjust knob setting.

.

a

Bypassing Effects

.

At any time you can bypass the effects, thereby allowing the direct signal to pass through the
DEP unchanged. This can be done in two ways:

.

A

by turning the MIX knob all the way to the left,

.

by connecting a footswitch to the [BYPASS] jack and pressing the footswitch.

.

a

Each time the footswitch connect to the [BYPASS] jack is pressed.

.

a

On the rear panel you will find a footswitch jack labeled [BYPASS]. This is a mono jack with conn-
ection for a normal momentary footswitch. The footswitch must be plugged in before the DEP
has its power turned on.

.

a

Placement and Installation

.

The DEP may be mounted almost anywhere when it's needed: on a table, on top of an amp,
neto to a mixing console. In any case, make sure to place it safely where it will not fall or be damaged.

If it will be on furniture, make sure to attach the rubber feet provided to the bottom of the unit.

While the DEP itself doesn't generate any magnetic or hum fields, its power supply may do so.
Make sure to place the power supply away from other audio equipment that is sensitive to induced
fields, and away from the signal wiring. In rare instances, the DEP itself may pick up noise fields
generated by other equipment such as large power amplifiers; in this case, move the DEP until

the noise goes away.

.

a

Rack Mounting

.

The most secure mounting is on a "universal" rack shelf, available from various rack manufacturers
or your music dealer. The DEP's height conforms to single-space ounting, and up to three

DEPs may be mounted side-by-side in a standard universal EIA 19" equipment rack.

Flange/Room

Chorus/Room

Rotary-

- The first multieffects program is a layered stereo flange and large room reverb. It

works great on guitars, synths and electric pianos.

- The second multieffects program is a layered stereo chorus and large room reverb.

Also that one works great on guitars, synths and electric pianos.

The Rotary effect emulates a rotating speaker. This effect was extremely popular during

the 1960s and was achieved by mechanically rotating the speakers to produce complex timbral

changes. The lezlie speaker system is most often used with tone-wheel organs, but is occasionally
used for guitar amplification as well. When changing the speed between fast and slow, the effect

will slowly ramp to the new speed rather than change abruptly, just as the original would do. Note:
When using the Rotary program, the Mix parameter should be turned all the way to the right.

On the chorus and flange programs, the Rate control sets the speed of the chorus or flanging
sweep. When the chorus rate is increased, the depth is similarly decreased to maintain a constant
pitch shift. On the Rotary program, the [VARIATIONS] knob controls the speed of the Lezlie motor,
either fast or slow. On the Flange/Room and Chorus/Room programs the [VARIATIONS] knob

edits the reverb decay time.

Delay is a discrete echo repeat, unlike the rapid wash of repeats that create reverb effects. It is us-

ful for adding depth to a track or performance if reverb is adding too much coloration to the sound.

Delay- This program provides a delay of up to 1000 ms. The delay time can be adjusted interms of
delay and decay times. This is a useful utility program which can add space to vocals or instruments

without "muddyingup" a mix.

Delay/Room - The third multieffects program adds a Room to the different delay presets.

This control sets the time between the input signal and the first delay tap.

Tremolo is an amplitude modulation of the signal. It is useful for adding warmth and life to standing

electric piano orguitar's chords.

Tremolo- This program provides an amplitude modulation of the input signal and is normally used
as "WET" effect without adding direct sound or adding a few percentage of

it, so to avoid the direct

sound to cover the amplitude modulation.

This control sets the amplitude modulation rate.
