Power And Indicators 

Problem 

Remedy  

No Power 

1.  Confirm that the rocker switch is in the “ ON”  position, and that the light is 

illuminated. 

2.  Confirm  that  power  connections  are  secured  at  the  amplifier  and  at  the 

receptacle.  Make  sure the receptacle  is active,  outputting  the  proper  mains 

voltage. 

For model VM-80V perform the following: 

Remove power cord from AC outlet and the machine and then using a flat 

head  screwdriver,  remove  fuse  holder  located  directly  below  the  power 

connector on your amplifier. Confirm that the fuse is good by looking for the 

wire connected between the ends of the fuse. If the wire is broken, replace 

the fuse with another, with the same rating. 

 

For model VM-10AN perform the following: 

Remove  the  power  cord  from  the  AC  outlet  and  then  using  a  philips 

screwdriver, carefully remove the cover of the machine. Locate the fuse near 

the power socket on the printed circuit board. Confirm that the fuse is good 

by looking for the wire connected between the ends of the fuse. If the wire is 

broken,  replace  the  fuse  with  another,  with  the  same  rating.  Reinstall  the 

cover of the machine. 

 

 

11.2 

Audio Signal  

(VM-10AN Only) 

 

Problem 

Remedy  

No audio at the output 

device, Regardless of Input 

Selected 

 

1.  Confirm  that  your  sources  and  output  device  are  turned  on  and  connected 

properly. Audio signals connected to the input of your amplifier should be 

properly wired to the output of your source. Audio signals connected to the 

output  of  your  amplifier  should  be  properly  wired  to  the  input  of  your 

amplifier or recorder. 

2.  Confirm  that  any  other  amplifiers  in  the  signal  path  have  the  proper  input 

and/or output selected. Pay special attention to input amplifiers that may be 

built into your amplifier or recording device. 

Audio level is too low 

 

1.  Confirm  that  the  connecting  cables  are  of  high  quality  and  properly  built. 

Take  special  care  in  noting  the  wiring  configuration  of  balanced  to 

unbalanced cables.  

2.  Check level controls located on your source input device or output device.
