To Next PageTo Next PageWhy does my Xantech PA435X sound cut in and out?
If the sound from your Xantech Amplifier cuts in and out every 3 to 5 seconds, it might be because the speaker load impedance is less than 4-Ohms in Stereo mode, or less than 8-Ohms in Bridged mode. To resolve this, make necessary changes to your speakers to achieve a higher impedance.
What to do if Xantech PA435X Amplifier becomes very warm and shuts off?
If your Xantech PA435X Amplifier becomes very warm, shuts off, and doesn't automatically turn back on, set the POWER switch to the MANUAL OFF position for 15 seconds, then back ON. If you're using the REMOTE ON/OFF jack, unplug it for 15 seconds, then plug it back in.
What to do if Xantech PA435X Amplifier does not turn off?
If your Xantech PA435X Amplifier doesn't turn OFF even when both REMOTE input voltages go to 0 Volts and the logo remains illuminated, ensure that the Front Panel POWER switch is set to the REMOTE ON/OFF (OUT) position.
Why is there no sound from CH2, CH4 on my Xantech PA435X Amplifier?
If you're not getting any sound from CH2 and CH4 on your Xantech Amplifier when stereo operation is desired, it's likely that the BRIDGED/STEREO switch is incorrectly set to the BRIDGED position. Set the switch to the STEREO position.
How to troubleshoot Xantech Amplifier when the power indicator doesn't light?
If the rear panel power indicator on your Xantech Amplifier doesn't light up and there's no sound, check the line cord to ensure it's making good contact in a live AC outlet. If REMOTE CI jacks are being used, verify that the applied voltage is between +5V and +30V DC with the correct polarity.
