  Several factors could cause a lack of sound from your Cyrus Amplifier. Here's what to check: * Ensure the amplifier (or power amplifiers) is not switched off or in standby mode. The standby indicator should be WHITE. * Make sure mute is not activated; deselect mute if it is. * Verify that the source is working correctly (e.g., CD is playing, not paused). * Confirm that the sample rate from the source is within the amplifier's specifications and that the program is encoded as two-channel stereo. * Check that the balance control is not at an extreme limit; centralize it. * Inspect your speakers for blown fuses and replace them if necessary. * Examine speaker cables and interconnects for faults; check connections and replace cables if needed.

What to do if my Cyrus Pre-XR Amplifier standby is activated randomly?

  Julia SmithAug 6, 2025
  If your Cyrus Amplifier enters standby mode unexpectedly, here are a few things to consider: * The auto standby feature might be enabled. The unit will automatically switch to standby after 20 minutes of inactivity to save energy. * The touchpads may need calibration. Manually operate the Standby touchpad from the front panel to calibrate them, especially after disconnecting the unit from the mains. * The sensitivity of the touchpads might need adjustment. You can change the sensitivity settings in the setup menu.
