Re: ps604 solid red all inputs

Hi Masroor,

Sorry for the trouble. From the installation guide: "All four LEDs will display solid red when all outputs are muted due to an amplifier fault, or if there is a power supply fault".

Since you've ruled out the AC power, I suggest disconnecting any loudspeaker wiring. If the LEDs persist, the product has failed and should be serviced. Please contact your sales engineer or support contact:
