pop-ing sound from amplifiers with USP2 cards

4 posts in this topic

Hi everyone,

i am wondering if any of you experience the pop-ing sound from the speakers when powering up or shutting down the amplifiers.

my setup is as follows:

Crown CTS 600 amplifier with IQPIP-USP2 card attached to JBL Control 25AV speakers.

please give me your comments.

Thank you.

regards,

Vincent

Hi Brad,

my colleague has rectified the problem.

The fault was found in the earlier batch of CTS amplifiers, just need to service some components and it will be all system go.

Thank you.

regards,

Vincent
