User manual DOD FX53

[. . . ] GROUNDING OR POLARIZATION: Precautions should be taken so that the grounding or polarization means of an appliance is not defeated. POWER CORD PROTECTION: Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance. SERVICING: The user should not attempt to service the appliance beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel. [. . . ] · 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. 2) KARAOKE INPUT - Connect high impedance 1/8 stereo CD input cable here. 3) LOW IMPEDANCE INPUT - This is the insert used for Low impedance XLR microphone input cords. 4) LOW IMPEDANCE OUTPUT - This is the insert used for Low impedance XLR output cords. 5) HIGH IMPEDANCE LEFT / MONO OUT - This output jack is used for the insertion of a High impedance 1/4 cord. 6) HIGH IMPEDANCE RIGHT OUT - This output jack is used for the insertion of a High impedance 1/4 cord. 7) AC POWER INPUT - Connect the supplied AC power adapter to this jack. Use only the adapter supplied with the VoFX. Use of any other adapter may damage the unit. 7) POWER CORD STRAIN RELIEF - This clip prevents the AC power cord from being accidentally pulled out. 5 Signal Processing Signal Processing SECTION 2 - PROGRAMMING THE VoFX The VoFX is designed to be both easy to program and flexible. The structure of an VoFX Program is logical, and it doesn't require a lot of time to master. To Select Programs in the VoFX: 1) After you power up, use the Data wheel to scroll through the Programs. The following procedure is an example of how to modify your Programs. Suppose that a Program which has a 100 ms mono delay, a medium chorus, noise gate, EQ, Mic Driver, 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: 1) Use the Data wheel, or the Bank and Program selector footswitches to select the desired Program. The Delay group Status LED begins flashing and the display reads: 11 7 Signal Processing Signal Processing 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 41 and 49 in the Echo(not Multi-Delay) Group. 4) Use the Data wheel to scroll until the the display reads: 41 . 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. You can manipulate any effect setting in the VoFX by pressing the associated Effect 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 below. Storing Programs The VoFX helps you remember whether or not you've stored the Program you're working on by lighting the Store LED under the bottom right corner of the display when the selected Program has been edited. [. . . ] Increased feedback settings can produce very spacey sounds, reminiscent of late 60's and 70's music.

This effect was offered in the vintage amplifiers of yesterday, but now it has become more popular than ever. The FX53 offers 9 tremolo speeds ranging from 2. 0Hz - 9. 0Hz RING MODULATOR The Ring Modulator produces mathematically related sounds rather than harmonically related sounds. [. . . ]
