Hi! I recently bought my Marshall DSL 100 HR. There is a silent recording mode. If my understanding is correct when the amp is in a standby mode only preamp section is active. Can I use my amp in standby mode for silent recording at home without a load/cab?

I would monitor it via my soundcard. Just to be clear I would not activate the 100/50 power amp section only stay in STB mode.

Could this cause any harm to the amp?

Thanks.
