In this guide, you will learn about the basic principles of the DMR8: recording, overdubbing, punch-ins and automated mixdown. In addition, you will learn about the operational principles of the DMR8, the monitoring system, and the use of the internal effects. This guide is not a substitute for the operational manual. However, it may raise points that you wish to explore further using the manual, and furthermore, once you have worked through this guide, ideas presented in the manual will probably make more sense. In any case, after you have used this guide, we recommend that you read at least the first two sections of the manual to give yourself more operational background on the DMR8. What you will need Monitor speakers DMR8 R-DAT page 1 This first session assumes that you will be using a stereo drum machine to lay down one stereo pair of tracks and another line level instrument (say a mono keyboard) which you will use to lay down another track at a later time. If you do not have access to these instruments, you can use pre-recorded sources (music and sound Since the DMR8 cannot accept analog signals directly, it is necessary to use an A/D convertor (the Yamaha AD8X 8-channel AD convertor). This accepts line-level balanced inputs through XLR connections. Without an AD8X you cannot proceed further. Microphone level signals will require a microphone pre-amplifier such as the Yamaha HA8 8-channel microphone pre-amplifier. It is assumed that you will be mixing to DAT, using coaxial digital connections on the DAT machine. Finally, you will need either a power amplifier and pair of reference monitor speakers (preferred), or a pair of reference headphones. This is not a complete list of the connections possible to and from the DMR8 — for instance, the mixdown can be performed to an AES/EBU format digital recorder, or to an analog recorder. However, this "skeleton" line-up allows you to work easily with the minimum of connections. How this guide is organized Follow the instructions in this guide in order. In this way, you will find a logical order of doing things. Of course, since recording is more of an art than a science, there is no "right" order of doing things — but in the case of using an unfamiliar piece of equipment, it is probably easier if you follow someone else's previously-charted course first of all. Keys that you should press on the DMR8 are shown in the following way: C MIXDOWN ) . Up-and down-arrow keys (sometimes used as increment and decrement) are shown as CT) and CD . Every so often in the text, there will be a "check panel" so that you can confirm that everything is as it should be, or if we feel that there is a special need for you to check a point. These will appear as follows: FX). The numeric LED should stop flashing when you or, if a screen display is being shown for checking: page 2 (1) Unpacking First, check that you have the following included in the packing with the DMR8: 1 X DMR8 main unit 1 x 25-pin-25-pin straight cable ("JAE" connector) - (A-D8X -> DMR8) 1 x 25-pin-25-pin crossed cable ("DDK" connector) - (DMR8 » DMR8) 1 X 15-pin control cable 1 X 8-pin DIN cable (DMR8 <- » SPX1 000/DEQ7/ DMP7D) 10 x M20P tapes 1 X MCD64 RAM card 1 X DMR8 soft cover 1 X M20CL head cleaning tape a) Unpacking the DMR8 GET SOMEONE TO HELP YOU UNPACK THE DMR8! The DMR8 weighs over 30kg (66lbs), and is quite bulky. For your own sake, and that of the DMR8, do not attempt to unpack and install the DMR8 by yourself. PREPARE A LANDING-SITE Make sure that there is a sufficiently strong and stable level surface on which the DMR8 can be sited. There should be sufficient space not only for the DMR8, but also for ventilation on all sides except the front. The DMR8 should not be placed directly under a shelf - ventilation is needed on the top as well. You will need to access the rear panel, so make sure that you can reach it without too much trouble. Place the DMR8 on its intended site. b) Unpacking the AD8X INSTALL THE AD8X For now, the AD8X is best placed on a flat surface (not the top of the DMR8, as this needs to be kept clear for cooling purposes). Do not put anything on top of the AD8X, as it FORMAT REC+PLAY >TOConly COMPLETE NO page 3 gets warm in operation. The AD8X can also be rack-mounted. In this case, remove the feet, and allow a 3U space in your rack, as a 1 U space is required above the AD8X for ventilation. CONNECT SOURCES TO THE AD8X Use XLR connectors to connect your sources to the AD8X (unbalanced sources may be used, though you may want to use a Dl box between the drum machine/synthesizer and the AD8X). MAKE THE POWER CONNECTIONS Both the DMR8 and the AD8X need AC power. Make sure that your power supply matches the voltage requirements on the back of the DMR8 and the AD8X. Use the usual commonsense rules when choosing the power supply - avoid putting these units on the same circuit as devices which generate large transients (refrigerators...
