DSA250i and DSA230i:

 

 

Modules connected within a

Supplied Link Cable

Check link cable for proper operation

or more drivers

 

 

No output

Incorrect connections

Check that input cabling to the

 

 

module is wired correctly for the

 

 

+/- signal wires and cable shield.

No output

Module is off

Check that power is supplied to the

 

 

module power cable and that the

 

 

cable is connected to the module.

No output

Module is off

Check the fuse on the power

 

 

end of the module. Replace if

 

 

blown. If the fuse blows again,

 

 

the module requires service.

No output

Amplifier is off

Using DSAPilot, check that

 

 

the power management functions

 

 

are set correctly.

No output

No input signal

Using DSAPilot monitoring

 

 

function, check that there is signal

 

 

at the input. If not, disconnect

 

 

and check for signal on the audio

 

 

input cable to the module.

No or low output

Input level is not set correctly

Using DSAPilot, check that the

 

 

gains for the input(s) being used are

 

 

set properly.
