distributed (split) to other amplifiers. In some projects, the same input may be looped through to multiple
amplifiers using this method. Up to 6 amplifiers can be looped together without any noticeable loss in level.
A distribution amplifier should be used when more than 6 amplifiers need to be looped.

The XLR’s are wired as follows: 

Pin 1:

 Shield.  

Pin 2:

 Hot, +, Positive. 

Pin 3:

 Cold, -, Negative

Fuse Sizes

Mains 115 VAC - 8 Amperes Slow Blow
DC - 2 x 10 Amperes Slow Blow

Notes:

The DC fuse is located on the circuit board. This is a feature of the AMIS series amplifier,
which is equipped with a current limiting circuit preventing excessive DC current, thus
eliminating the risk of blowing high tensions fuses.  In the unlikely event that the DC fuse

actuates, the output transistors should be checked, as it is probable that the amplifier has been subjected to
very extreme conditions.

Important Safety Information

1. 

Save the carton and packing material even if the equipment has arrived in good condition. 

Should

you ever need to ship the unit, use only the original factory packing.

2.

 Read all documentation before operating your equipment. 

Retain all documentation for future

reference.

3. 

Follow all instructions 

printed on unit chassis for proper operation.

4. 

Do not spill water or other liquids into or on the unit, 

or operate the unit while standing in liquid.

5. 

Make sure power outlets conform to the power requirements 

listed on the back of the unit.

6. 

Do not use the unit if the electrical power cord is frayed or broken. 

The power supply cords should

be routed so that they are not likely to be walked on or pinched by items placed upon or against them,
paying particular attention to cords and plugs, convenience receptacles, and the point where they exit from
the appliance.

7. 

Always operate the unit with the AC ground wire connected 

to the electrical system ground.

Precautions should be taken so that the means of grounding of a piece of equipment is not defeated.

8. 

Mains voltage must be correct and the same as that printed on the rear of the unit. 

Damage caused

by connection to improper AC voltage is not covered by any warranty.
