UNPACKING AND INSPECTION

Your XT was packed carefully at the factory. The shipping carton was designed to protect the unit during shipping. Please retain this container in the highly unlikely event that you need to return the XT for servicing.

 

The shipping carton should contain the following items:

 

• ADAT-XT with the same serial number as shown on shipping carton

 

•

Power Cable

 

•

Optical Cable

 

• XT remote control unit

 

•

This instruction manual

 

• Blank S-VHS ST-120 cassette

 

•

Alesis warranty card

J

It is important to register your purchase; if you have not already filled out your

warranty card and mailed it back to Alesis, please take the time to do so now.

AC POWER HOOKUP

With the XT off, plug the female end of the power cord into the XT’s [POWER INPUT] socket and the male (plug) end into a source of AC power. It’s good practice to not turn on the XT until all other cables are hooked up.

The XT works with any AC voltage from 90 to 250 volts, 50 to 60 Hz. This eliminates the need for transformers or voltage switches. Your XT was supplied with the correct power cord for your country or local area, however only the following alternative power cords are approved for use with ADAT:

• For 90-120 VAC 50/60 Hz operation in the US, Canada and/or Japan, use Alesis UL/CSA power cord #7-41-0001.

• For 240 VAC 50 Hz operation in England, use Alesis Power cord #7-41-0004.

• For 220 VAC 50 Hz operation in Europe and Scandinavia, use Alesis EU power cord #7-41-0002.

 

• For 240 VAC 50 Hz operation in Australia, use Alesis AS power cord #7-41-0003.

 

The XT’s IEC-spec AC cord (do not substitute any other AC cord) is designed to feed

 

an outlet that includes three pins, with the third, round pin connected to ground. The

 

ground connection is an important safety feature designed to keep the chassis of

 

electronic devices such as the Alesis ADAT - XT, BRC and AI-1 at ground potential.

 

Unfortunately, the presence of a third ground pin does not always indicate that an

 

outlet is properly grounded. Use an AC line tester to determine this. If the outlet is not

 

grounded, consult with a licensed electrician. When AC currents are suspect of being

 

highly unstable in VAC and Hz, a professional power conditioner should be used.

Alesis cannot be responsible for problems caused by using the XT or any associated

equipment with improper AC wiring.

 

AVOIDING GROUND LOOPS

 

In today’s studio, where it seems every piece of gear has a computer in it, there are

 

many opportunities for ground loop problems to occur. These show up as hums,
