Topping TP30 cutting out unexpectedly

[Jon Bradbury]

Hi all

I have a Topping TP30 DAC / Amp combo here as my desk amp in my study - it is connected to an OpenPeak tablet thing (sold in the UK by O2 as a "Joggler") via the analogue audio out. It's plugged into an old (very old) pair of JPW Sonata loudspeakers. The whole setup sounds really sweet.

However, there's a problem. Since connecting the Sonatas, the amp is cutting out at frequent intervals. It's like it is going into protection mode, and I can also hear the relay clicking occasionally. Turning it off then on again will reset it for a short time.

Anyone got any ideas as to what is wrong? Is it struggling to drive the speakers?

Cheers

JonB

Can you measure the impedance of the speakers? The amp may be clipping because of low impedance.

Hi,

Check your speaker cables for any stray shorting whiskers.

rgds, sreten.

The amp should have no problem at all driving the JPW's.
