This section provides a brief tour of the XT, shows you how to format a tape, record and maunal, set locate points, auto punch-in and out, bounce tracks, and points out other various features.
Device A One path goes from device A to ground via the ground terminal of the three- conductor AC power cord, but A also sees a path to ground through the shielded cable and AC ground of device B.
Never unplug a cable by pulling on the wire itself. Always unplug by firmly grasping the body of the plug and pulling directly outward.
The XT provides eight dBV analog outputs via phono connectors. We cannot overemphasize the importance of this. Push gently on the center of the tape cassette until the XT draws the tape inward; never force the tape into the cassette door.
Similar to formatting a floppy disk to use on a computer or sampler, formatting an XT tape time-stamps the tape to single-sample accuracy so that audio is referenced to an accurate time base. The process involves formatting a tape see previous tutorialputting one or more tracks into record-ready, adjusting record levels on your mixer, setting the input monitor mode, locating to the start tape address and engaging record.
Get familiar with them by using them while watching the TIME counter. Press with [PLAY] to initiate review mode. To play back a recording: Both Locates 1 and 4 are assignable to any tape position using the methods described in the previous section.
Auto recording stops and starts recording automatically at predetermined times. This is useful when you want to precisely punch in to a specific place on one or more tracks. RACK It is possible to copy the audio material from one track to another on the same tape within the XT without leaving the digital domain and without the need for any audio cables.
In fact, you can copy up to 4 tracks at a time using the Track Copy feature. For more information on using the Track Copy function, see page These are compatible with low- impedance, unbalanced, dBV outputs typical of equipment such as mixers, synthesizers, samplers, direct boxes, etc.
The unbalanced input jack wiring convention is as follows: Larger Key Notch Note: The larger of the two outer key notches is at the bottom. Both the unbalanced and balanced inputs and outputs may be used simultaneously. This requires a male-to-male, 9-pin D connector cable for each additional machine in the chain.
This allows you to bounce audio between multiple machines within the digital domain. ASIC This chapter is designed for operators who may not have experience working with digital audio. All functions of the XT with the exception of synchronization and digital audio are explained here in detail. If you are already familiar with multitrack recording concepts, you may not need to read this chapter. Basic Operations Be sure the tape is completely rewound.

This insures continuous time-stamping when a tape plays from beginning to end. To extend the format on a partially formatted tape: It shows the current level of each of the eight audio tracks, it shows the current tape position numerically in hours, minutes, seconds, and ths of seconds, and shows the current modes of the many parameters available. They indicate that the parameter for which they are named has been selected or turned on.
Basic Operations This icon indicates that you have manuxl Track Delay function turned on. When in Edit Mode, this icon indicates that you are editing a tracks delay amount, which will appear in the TIME counter.
A number from 1 to 8 will appear next to the EDIT icon to indicate which track is being edited. These determine what signals will be recorded manuall the XT. The currently selected input mode is indicated in the lower right corner of the display: Next, select the source tracks, select record enable the destination tracks, and initiate recording. Continuous, Momentary and Off.

If the tape is moving, it will stop before ejecting. Entering play or record more will also thread the tape, if it was previously unthreaded. When recording, pressing [STOP] will exit record mode and stop the transport. The longer crossfade time allows for a smoother transition and is more useful when punching in new material that is very different from what is already on tape, or when punching in low-frequency signals. Crossfading always begins at the punch point and continues for the amount of time you have specified.
The counter will not elapse in real time when the pitch is set to a value other than zero. The lowest sampling rate is If you need one track to play back earlier than the others, try offsetting all other tracks by the same amount. If this is not to your liking, this safeguard may be disabled. However, Alesis recommends doing so only when you absolutely have no other alternative.
The loop limit will be enabled again once [STOP] is pressed. ECORD The Auto Record function lets you determine exactly where recording should begin and end beforehand, so that the machine automatically takes you in and out of record. Locate Points 2 and 3 determine the in and out points.
Basic Operations automatically recognizes the shorter length of the ST because the hubs used in the cassette are larger. In this situation, the XT assumes the tape length to be that of a ST tape. During power-up, the XT checks the footswitch to determine whether it is normally open or normally closed type, and calibrates itself accordingly. Combine this feature with the ability to bounce tracks in the digital domain, and you have the ability to perform cut-and-paste style assembly editing.
Synchronization requires a dual male, 9 pin D connector cable for each slave to be synchronized. Use only Alesis cables.
Alesis Sync Cables are available in three different lengths: Other types of cables may cause incorrect commands to be received, and erratic sync performance. These 8 channels are routed in a one-to-one relationship to the 8 tracks of the target XT which can record the digital audio. If you wanted to use the same take of the background vocals of a song from the first chorus for chorus 2 and 3, you could bounce those track s to another machine.
XT would cause some phase cancellation when combined with the original signal. The digital representation of the data as stored on tape was therefore inverted relative to the analog input i. These applications are not broken down into great detail.
Therefore, where applicable you will need to refer to other sections of this manual for instructions on how to setup the XT for a particular job. Naturally, the audio signals would need to be split and connected to both sets of inputs. By splitting xf system into two or into two sets of machinesyou can offset the second set by a specific amount of time. Applications If your sequencer generates MMC commands, you should be able to put your sequencer into play and have the XT follow along.
When a PLAY command is sent from the sequencer, the XT is issued a locate command, telling mabual where the sequencer is positioned in timecode. This means you can set a Locate at one adta, another Locate at another position, mnaual have one of the slave ADATs offset by the amount of time between those two Locate positions. Edit Mode will now be selected. Write this number down or memorize it.
With analog recording, tape containing millions of tiny magnetizable particles move past a record head. Digital Recording Concepts Digital audio requires lots of numbers to represent an analog version of the same sound. Analog signals may require at least 20kHz frequency response to reproduce audio faithfully. Digital signals for the same 20 kHz audio requires a frequency response of several million Hertz. No user adjustment is necessary. Over the course of time, depending on the quality of the tapes used and the environmental conditions where the ADAT and its tapes are stored, head cleaning may become necessary.
