Alvarez SA1521z 사용자 설명서

Place the new amplifi er assembly 

(part #0013838-00) where the old one 

was. Follow the same steps as above, 

but backwards 6 to 1. Remove the 

serial number from the faulty amplifi er 

assembly (as shown in picture above) 

and place on the new amplifi er 

assembly. Power up the SA1521z and 

relish in the fact that you just replaced 

an amplifi er assembly. Hats off to you for 

a job well done! 

This is what it looks like with the cables 

removed from the amplifi er assembly: 

(1) led PCB cable, (2) solid blue, (3) blue 

and black, (4) yellow and black, and 

   

(5) solid yellow. Make sure the cables are 

reconnected to the same terminals they 

were removed from (but on the new 

amplifi er assembly). See steps 6a and 6b 

below for closeups of the photograph 

above.

A closeup of the led PCB cable 

connector is shown above. The black 

wire of the cable is closest to the edge of 

the amplifi er assembly. The cable only fi ts 

in one way. 

 The faulty amplifi er 

assembly must be returned to LOUD 

Technologies. The address should 

be on the return shipping label that 

was provided with the new amplifi er 

assembly. If not, the return address is at 

the top of this page. Also, please write 

the order number and service request 

number (ex: 1046256-1203935) in big, 

black, bold numbers on the outside of 

the box. This helps expedite the return.
