Post Repair Advice
Following is some common sense from technical point of view advice on using your sub-woofer or any other audio amplifier in that matter. Some of it may be obvious, some not so, but having these simple steps in mind would put less stress on your amplifier and ultimately result in better reliability.
- Never connect/disconnect signal cables to your amplifier while powered (valid for units on both ends of the cable).
- On power ON/OFF make sure you stop the signal to the amplifier first, i.e. when power up, don’t have your source signal running already, so when the amplifier starts, it immediately outputs high power to the speaker. And vice versa, when powering down, don’t cut the power while it plays on high volume – turn the volume down first, or better, completely stop the source signal.
- Do not power the amplifier up again immediately after power down – particularly important for PSW-series sub-woofers. Give it a minute after power down to self discharge the stored inside energy, as otherwise it may not start properly.
- As always advisable, always turn off from the mains switch when not in use – again particularly important for PSW-series sub-woofers, due to not having real stand-by feature. Keep the mode switch on the back to ‘Manual’ and switch off. Just a few ideas how you can automate/semi-automate this process using one of the devices linked from Amazon below.
