DIGITAL EFFECTS MODULE OWNER'S MANUAL Introduction . Thank you for purchasing the DEP (Abbrev For: Digital Effects Processor). To take full advantageof the DEP 's functions, and to enjoy long and trouble-free use, please read this user's manual carefully. How To Use This Manual . This manual is divided into the following sections describing the various modes of the DEP. Though we recommend you take time to read through the entire manual once carefully, those having general knowledge about effects devices should use the table of contents to reference specific functions. Chapter 1: Your First Session with theDEP . A basic introduction on operating the DEP, auditioning the factory programs, and adjusting levels. Chapter 2: Connections. This chapter explains how to connect the DEP to an instrument, mixing console or an amplifier. Chapter 3: Overview of Programs. A summary of the 16 programs in the DEP, including the function of the Adjust knob. Chapter 4: Description of Controls. An explanation of all connectors and knobs on the DEP. Use this chapter as a quick reference guide when searching for specific information. Chapter 5: Troubleshooting. This chapter contains troubleshooting tips and service information should problems occur. Conventions . The knobs and rear panel connectors are referred to this manual just as their names appear on the DEP, using all capital letters and in brackets ( Example:[INPUT] Knob, [VARIATIONS] Knob, etc.) . When something important appears in the manual, an icon (like the one on the left) will appear in the left margin. This symbol indicates that this information is vital when operating the DEP.

When the footswitch is in the state of "OFF", the function will be "EFFECTS". In the other hand, when the footswitch is in the state of "ON", the function will be "BY-PASS". Unpacking and Inspection . Input (Left/Mono & Right) . Your DEP was packed carefully at the factory, and the shipping carton was designed to protect These are 1/4" unbalanced phone jacks which connect to sources such as the effects sends of the unit during shipping. Please retain this container in the highly unlikely event that you need to mixing consoles. They may be used with nominal input levels from -20dBV (guitar level) to +4dBu. return the DEP for servicing. For mono applications, use the [LEFT/MONO] input. The [LEFT/MONO] input jack is normalled to the [RIGHT] jack. This means that when nothing is The shipping carton should contain the following items: . plugged into the [RIGHT] input jack, the signal present at the [LEFT/MONO] input is routed to the This instruction manual .

These are 1/4" unbalanced phone jacks which connect to devices such as the effects returns on a mixing console or power amplifier inputs. For mono applications, use the [LEFT] output. Basic Connections . The DEP will work in many different applications, whether you are connecting an instrument dir-ectly into it, or connecting it with a mixing console. Briefly described here are the basic conne -ctions to get you up and running quickly. For more information on connections, please refer to Chapter 2. Mono In, Mono or Stereo Out: Connect a 1/4" phone cord to the [LEFT/MONO] INPUT of the DEP from a mono source. (The Left input will feed both inputs.) Connect another 1/4" phone cord from the [LEFT] OUTPUT of the DEP to an amplification system or mixer input. Additionally, you could connect a second 1/4" phone cord to the [RIGHT] OUTPUT for use with a stereo amplification system, or two mixer inputs. Stereo: Connect two 1/4" phone cords to the [LEFT/MONO] & [RIGHT] INPUTS of the DEP from a stereo source , and two 1/4" phone cords from the [LEFT/MONO] & [RIGHT] OUTPUTS of the DEP to a stereo amplification system or two mixer inputs. FROM INSTRUMENT OR EFFCTS SEND LEFT INPUT RIGHT INPUT LEFT OUTPUT RIGHT OUTPUT 010010 0 10 If connecting to a mixing console's aux sends/returns, you will want to turn the [MIX] knob fully clockwise so that the DEP outputs only wet (effected) signal. 16 1 Powering Up . CHAPTER 4 . After making your connections, turn on the system's power using this procedure: . DESCRIPTION OF CONTROL . A Before turning on the DEP's power, check the following items: . Front Panel . Have all connections been made correctly? . Input Level . Are the volume controls of the amplifier or mixer turned down? . The [INPUT] Level controls the level of the signal being fed into the DEP. The DEP can Insert the Power jack into the [POWER] input on the rear panel of the DEP and plug the operate with signal levels anywhere from +4dBu pro audio gear to-20dBV guitar level signals. Power adapter into an AC outlet. To set the input level, watch the [SIGNAL] LED while adjusting the [INPUT] level (see below). Upon power-up, the Power On LED will illuminate. A Turn on the power of the amplifier/mixer, and adjust the volume. Mix Level . The [MIX] Level controls the balance between the uneffected signal coming through the inputs and Setting Levels . the effects being generated by the DEP. When [MIX] is turned all the way to the left, the input Proper setting of the input and output levels is crucial in order to achieve the aximum signal-to- signal will be sent straight to the output with no effects added. When [MIX] is turned all the way to noise ratio. As a good rule of thumb, it is usually best to set both input and output level controls at right, only the effects will be sent to the outputs with none of the original input signal mixed in.
