Intermittent noise from the speaker (Popping Noise)¶
Symptom:
Sometimes there’s this noise in my Spark.
Speaker rattles/crackles when playing.
There's a popping noise with Spark.
Solution: - Verify if it’s the speaker rattle with certain frequency/volume -> RMA - Verify if it’s the popping noise when the amp is turned on/off -> RMA (see special case) or DOA
240520 updated:
When you turn on your amp, a constant supply of voltage runs through your amp. When you flip the switch and turn the amp off, you are disconnecting the high voltage of the power supply. When connecting or disconnecting high voltage, the surge of the voltages often produces a pop noise.
The popping noise you hear is likely caused by an aging IC on the PCB, which can no longer tolerate the high voltage. Over time, this component can degrade, losing its ability to effectively manage the voltage surges when the amp is turned on or off. While this noise does not affect the overall performance of your amp, it indicates that the IC is no longer functioning optimally.
This popping noise while turning off the Spark amp won’t affect anything. If you’d like to resolve the issue, I’ll be happy to help you return the Spark amp to our service center. Since your Spark amp might be already out-of-warranty, you will need to pay the repair cost ($80).
- Special Case:
If the amp is out-of-warranty and there is a popping noise when the amp is powered on/off, please ask the customer to provide a clear photo of the serial number.
Check if the 7th digit is 9 or 0: S040C59Axxxxx, S040C902xxxxx, and S040C90Cxxxxx
It means the amp was manufactured in 2019 & 2020
In this case, we'll assist the customer in returning/exchanging the amp (PG paid).
