Why no soud in Sonic Frontiers Line 2 SE preamp

I have Sonic Frontiers Line 2 SE preamp. Every function is working, but no output sound. Badly need advice for direction. Tubes are fine, Mute function works fine, Standby function works. I do not use remote control. When I turn on the line 2, there two red lights on main board. I contacted Part Connection and thy suggested new matched tube set. I borrowed new set and it still did not make output sound. Please help me.

Thyssen,

Double check all input and output connections.

What are you using for a front end source? CDP? TT?
If CDP does it have 2 sets of outputs? Maybe one set fixed, the other set variable? If so make sure you are using the fixed outputs.

Do you have something else you can use as a source, maybe a DVD player, hook it up to the preamp.

What power amp are you using? Could that be the problem?

If possible do you have a dealer or friend that you could take the Line 2 preamp to and hook it up on their system. That will tell you for sure if the preamp is, or is not, the problem.

When you first power up the preamp you should see 2 sets of 3 green lights on the front display panel.
*** ***
Do you get that on the front display of the preamp?

Then pushing the standby button a red "mute" is displayed on the front panel. Are you getting that on the front panel display?

After a systems check the red “mute” is replaced by “ Bal 1” on the front panel along with 2 sets of green numbers for preset volume levels. Are you getting that display on the preamp?

Now press the push button for source input desired. That input should be displayed on the front panel.

If all is ok so far next check to make sure the "Tape" push button has not been pushed and the preamp is set to tape loop. Press once and see what happens.

Next check the "SSP" push button has not been pressed. Press once and see what happens.

Post back your results.

Yes I have checked all connections and source outputs and even my power amp. They are all normal. Though, still my preamp sound level is too low. Why is my preamp output too low? what might be the main reason?

How does the music sound when listening to music from your system? Can you turn the volume control knob untill you reach the volume level that you desire? Does the sound start to distort?

Do you still have the remote control? If so, try using it to control the volume. The volume control knob on the preamp operates an optical reader. Maybe it is going bad. ???

The remote control operation, my understanding, does not use the optical reader.
