To prevent fire or shock hazard, do not expose this appliance to rain or moisture. 1-En CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. THE SYMBOLS ARE RULED BY UL STANDARDS (U. S. A. ) The lightning flash with the arrowhead symbol superimposed across a graphical representation of a person, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure; that may be of sufficient magnitude to constitute a risk of electric shock. The exclamation point within an equilateral triangle is intented to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 5A-En CD3000XL Operator's Manual i WARNING IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS WARNING - When using electric products, basic precautions should always be followed, including the following; 1) Read all the instructions before using the product. 2) Do not use this product near water - for example, near a bath tub, washbowl, kitchen sink, in a wet basement or near a swimming pool or the like. [. . . ] EVERY CD CARRIES THIS WARNING: "ALL RIGHTS OF THE PRODUCER AND OWNER OF THE RECORDED WORK ARE PROTECTED BY LAW. UNAUTHORISED COPYING, PUBLIC PERFORMANCE, BROADCASTING, HIRING OR RENTAL OF THIS RECORDING PROHIBITED. " This means that it is illegal to record from an audio CD without first obtaining prior permission from the holders of the copyright to do so. Failure to obtain copyright clearance could result in very serious legal consequences. The special sampling CDs contain sounds designed for sampling and are created for this purpose. These sampling CD are also subject to certain copyright restrictions and carry a warning something like the following: "EVERY EFFORT HAS BEEN MADE TO ENSURE THAT THIS CD CONTAINS SOUNDS YOU CAN USE SAFELY IN YOUR MUSIC. HOWEVER THE PRODUCERS OF THIS CD CANNOT ACCEPT RESPONSIBILITY FOR ANY DIRECT OR CONSEQUENTIAL LOSS THAT MAY RESULT WHEN USING THIS PRODUCT. " "PURCHASE OF THIS CD ENTITLES THE PURCHASER TO USE THE MATERIAL FEATURED IN THEIR MUSIC, NOT FOR THE CREATION OF ANY COMPETITIVE PRODUCT. ANY INFRINGEMENT OF COPYRIGHT WILL BE PURSUED TO THE FULLEST EXTENT. " This means that you may freely sample the sounds on the sampling CD but you may not use such samples for any commercial gain. Once again, if you are caught doing this, you may be sued by the copyright holders. THEREFORE, IN ALL OF THE ABOVE, WHENEVER YOU USE A SAMPLING CD, YOU HAVE TO HAVE PERMISSON, OR USE A COPYRIGHT FREE CD. WE CANNOT BE HELD RESPONSIBLE FOR ANY SUCH ACTION BROUGHT AGAINST YOU FOR VIOLATION OF THIS LAW CD3000XL OperatorÕs Manual Page 121 SAMPLE WHAT IS SAMPLING?Using a microphone, we can convert those changes in air pressure into rising and falling voltages. Once they exist in that format, we can process them through ANALOGUE TO DIGITAL CONVERTERS (ADC) to turn those voltages into streams of digital data. Once they exist as digital data, we can edit them with alarming precision. SOUND MIC VOLTAGE WAVEFORM ADC DIGITISED WAVEFORM In the ADC, the sound is `sampled' at a rate of 44, 100 times per second. If we take a lot of photographs in very quick succession, when we play it back, we have the illusion of movement. If we take enough samples, we get an accurate reproduction of the sound. To carry this analogy even further, if you think of the very early days of film where they didn't take so many frames in a second, the results were jerky and distorted. The same could be said about old samplers - because they sampled less (that is, the sampling rate was lower), the sound quality was not so good. In order to reproduce sound accurately, you need to sample at a frequency that is at least twice the upper reaches of the sounds frequency range. In other words, if a sound contains frequencies that extend to, say, 15kHz, you need to sample at 30kHz at least. Instruments such as cymbals which are very bright and contain many overtones need to be sampled at 40kHz. A bass drum, however, which has very few upper harmonics, could feasibly be sampled at 20kHz. The CD3000XL samples at 44. 1kHz, the same as compact disc so you can be sure you are getting CD quality sound from your sampler. [. . . ] Now replace the top panel, ensuring that the four top screws and rear panel screw are securely fastened. Once the boot up is complete, you will see the message: This will confirm that the FlashROM board has been `seen' by the CD3000XL. If two FMX008 boards are installed, the message will tell you "8MW fitted". CD3000XL OperatorÕs Manual Page 297 APPENDIX 3 IMPORTANT NOTES ABOUT INSTALLING THE FMX008 When you install the FMX008 board, please note that the following problems could be had. · · ALWAYS disconnect the sampler's mains lead from the mains outlet when opening the sampler's casework.
