advice required - speaker buzz following change of amp.
I'm using a set up with a CD player, DVD player, and Surround sound
processor and 2 channel Amp. I use the surround processor to drive the sub, centre and rears with an output to the 2 channel amp to drive the front speakers when using the surround system. I just replaced my existing amp with the Arcam and now I have interference which manifests itself as a low buzzing in the speakers unless the the 'direct' switch on the amp is pressed. This reduces the noise but does not eliminate it totally. I notice that with the direct switch off (such that the controls are not bypassed) adjusting the treble control on the amp has an effect on the interference. also I notice that with everything switched off at the front panel power switches - if I touch the interconnects from the DSP-E800 to the Arcam amp with one hand and the case of the Arcam amp at the same time I can feel a mild tingling in my hand....(not sure if this is normal - does not seem right.) looking for advice.... System is, should it be important... Arcam Alpha 7 CD, Arcam Alpha 7 Amp, Yamaha DSPE-800 and Tosh DVD. Mordaunt short Front and centre speakers (bi-wired) and an Eltax active sub & Eltax bipolar rears. |

further info...
With the interconnects disconnected from the DSP-E800 the Arcam amp is fine (interconnects from CD to amp still in place) When the interconnects between the DSP-E800 and the Arcam amp are plugged in AND the DSP is unplugged completely from the mains, the Speaker buzz is still present. SS |
