In this way, you can avoid damage to the connected devices. When you are connecting or removing the cables from the inputs or outputs ofthe XR-3, first make sure that the level of the input faders or volume controls of the connected channels is set to "0." • Even when you turn the power svyitch off (STANDBY) while the AC adaptor is connected, a small current always flows through the AC adaptor. Therefore, be sure to remove the AC adaptor when you are not going use the XR-3 for an extended period of time. • For safety, be sure to use the dedicated AC adaptor that comes with the XR-3. Installation • Do not subject the product to the following circumstances: * Extremely high or low temperatures, significant changes in temperature * Extreme humidity, or dusty conditions * Direct sunlight, or beside a heat-generating object such as a heater * Changes in the power voltage * Near a strong magnetic field (such as a TV or speakers) before using the XR-3.) 3 Precautions Before using the XR-3, it is a good idea to understand the differences between a radio/ cassette tape recorder that you might be accustomed to using (commonly called a "boom box") and a multitracker (abbreviated here as MTR). Using a cassette tape Both a boom box and an MTR have four tracks for recording. However, the same cassette tape would be recorded differently, as shown in the following diagrams. Standard boom box XR-3 On the standard boom box, both the A side and B side of the tape can be used to record four tracks, as shown in the diagram. You need to flip the tape over to record the other side. On the contrary, the MTR uses either the A or B side of the tape to record four tracks. That is, you never flip the tape over. Multitrack recording As explained in the previous paragraph, a boom box usually records data on each side of the tape in stereo (L, R). On the other hand, you can record four tracks individually, or two tracks simultaneously, on the XR-3. In this way, you can record many different musical instruments on different tracks. In addition, you can record a new sound on an empty track, while listening to sounds already recorded on the other track{s). (This operation is called "overdubbing." You can also mix multiple tracks while recording to another track. (This operation is called "ping-pong recording.") In this way, the MTR allows you to perform various recording techniques. The difference between a track and a channel "Track" and "channel" are sometimes used to mean the same thing. However, in this manual, these are differentiated as follows: The word "channel" is mainly used for mixer inputs/outputs, and the word "track" is used for recorder (tape) inputs/outputs. For example, we might say, "recording the sound of the guitar connected to Channel 1 onto Track 1." The XR-3 has two inputs: Channel 1 and Channel 2. It also has four tracks for recording and playback: Tracks 1, 2, 3, and 4. Tape and tape speed The XR-3 has been designed to use a high-position (QO2, TYPE II) cassette tape, such as the Maxell XL-II or the TDK SA series, for best performance. We recommend that you use one of these tapes, or an equivalent. The XR-3 also runs a tape at double speed (9.5cm/s), which is twice the speed of a standard boom box (4.75cm/s) for improved recording quality. Therefore, if you try to play back a tape that was recorded on the XR-3 on a boom box, it will not play back correctly because of the difference in the tape speed. If you wish to listen to an XR-3 tape on a boom box, first you need to dub the sounds to a master recorder (such as your boom box) using the XR-3's mixdown function. (Refer to page 20 for mixdown.) The time duration you can record on a tape using the XR-3 varies depending on the type of tape, as follows: Tape type Recording time (one side) Boom box XR-3 C-30 Approx. 15 min. Approx. 7.5 min. C-46 Approx, 23 min. Approx. 11.5 min. C-6D Approx. 30 min. Approx. 15 min. C-90 Approx. 45 min. Approx. 22.5 min. C-120 Approx. 60 min. Approx. 30 min. Note:- Do not use a C-120 tape. This tape is very thin, and may easily become tangled or cut on the MTR, on which you are likely to repeat various operations in a session. We recommend that you use a C-90 or shorter tape. Now, you understand some differences between the MTR and a boom box. In the next paragraph, we will explain the function oftheXR-3's controls and switches so that you will can prepare to use the XR-3. 5 Control panel and front and rear panels J- fIn n-1 IstOVU * ^ m\M y ®) y -g— - | | x> <§> P [in [fill | |il[^ 6 The words in square brackets [ ] refer to the printing on the front and rear panel.
