CHAPTER 4
DESCRIPTION OF CONTROL
The [INPUT] Level controls the level of the signal being fed into the DEP. The DEP can
operate with signal levels anywhere from +4dBu pro audio gear to-20dBV guitar level signals.
To set the input level, watch the [SIGNAL] LED while adjusting the [INPUT] level (see below).
The [MIX] Level controls the balance between the uneffected signal coming through the inputs and
the effects being generated by the DEP. When [MIX] is turned all the way to the left, the input
signal will be sent straight to the output with no effects added. When [MIX] is turned all the way to
right, only the effects will be sent to the outputs with none of the original input signal mixed in. By
keeping the Mix somewhere in the center, a blend of dry and wet signal can be achieved. With a
typical instrument setup (use with a guitar amp, etc.) the Mix is usually set around 12 o'clock.
When used with a mixing console, the Mix control should be turned all the way to the right (full wet)
so that the effects mix can be controlled from the mixer.
The [OUTPUT] Level controls the volume of the signal from the outputs. The typical level for this
control is 75%, but it can be raised or lowered as necessar
This red LED monitors the strength of the signal that is sent to the DEP. When the LED lights
up, the input signal is provocating "overflows" within the digital process and the output signal will
be potentially distorted so the [INPUT] level should be backed off.
The Program Select Knob is used to change programs.
The [VARIATIONS] Knob is used to edit aspects of the currently selected program. For example,
on a Concert Hall program, the Adjust knob edits Reverb Decay Time.
[VARIATIONS] is always active, so newly selected programs always read the knob setting.
This is a plug for connecting the SHOW Model 9VAC power supply (supplied).
The power supply included with the DEP is compatible with the electrical requirements of the
country of purchase, and should be connected to the proper electrical outlet. (In the USA, this is
120VAC.) The correct power supply must be used AT ALL TIMES. Any other power supply might
create a fire risk and/or permanently damage your unit. This damage would NOT be covered
under your warranty.

Powering Up
.
After making your connections, turn on the system's power using this procedure:
.
Have all connections been made correctly?
.
Are the volume controls of the amplifier or mixer turned down?
.
Insert the Power jack into the [POWER] input on the rear panel of the DEP and plug the
Power adapter into an AC outlet.
.
Upon power-up, the Power On LED will illuminate.
.
Turn on the power of the amplifier/mixer, and adjust the volume.
.
Setting Levels
.
Proper setting of the input and output levels is crucial in order to achieve the aximum signal-to-
noise ratio. As a good rule of thumb, it is usually best to set both input and output level controls at
3/4 or 75% of full. This will decrease the possibility of overload distortion and keep the amount of
background noise to a minimum.
.
If the Signal LED on the DEP begins to clip (turn red), turn down the Input level or decrease
the volume of the source (instrument, mixer send, etc.). If the DEP's level is causing the mixer
or amp to distort, turn the Output Level down. For more detail on level setting, see page 18.

What's on the Front Panel?

Signal LED.
The Signal LED displays the signal level coming into the Input. During normal
operation, If the signal level is at the maximum, this LED will turn red and you will begin to hear
the signal distort.
.
Power LED.
The Power LED is illuminated whenever the DEP's power adapter is plugged in.
Program Select.
The Program Select Knob is used to choose the program you wish to use.
Variations.
Each program on the DEP has one parameter which can be adjusted.
.
Depending on the type of program selected, this knob might alter reverb decay, chorus depth,
etc.
