Bose bass module 700 issue (CLICK sound while powering off)


Novice Member
Hi all,
I,ve recently bought module 700 and connected to my existing sound bar via Bluetooth and it works perfectly. But there is one time sound ( kind of CLICK) coming from module only when it is turned off at power source.

I thought something wrong and asked seller for replacement. They replaced it with brand new. Now even the new one is giving same sound.

Can anyone have this module and please check ?

Attached recording of that sound. If you observe carefully, there are 2 noises. The first little bit louder one is the sound of power SWITCH. Second sound is actually coming from module.

It's an anti-thump relay in the power supply probably. It lets the power supply fully energise before connecting the speaker so it does not "thud" when power is applied/removed. Quite normal with amps.

My AVR does it when powering up
