Why is there no sound coming from my Harman JBL CSA 140Z?

If you're experiencing no sound or low sound from your Harman Amplifier, several factors could be the cause. First, ensure that the input signal is present and at an adequate level. Verify that the Master Volume control is not turned down; if it is, turn it up. If a CSR-V is connected, make sure it is also turned up. When using the 70V or 100V outputs, confirm that the Hi-Z switch is turned ON. Finally, check that the power switch is in the ON position.
