sound through rears when on mute

Question for everyone with sp1 or 1.7

when playing a source with DD,DTS or Prologic does anyone get the sound coming out of the rears when on mute.Its not as loud as it was being played original but loud enough to hear it without straining.

regards

My SP-1.7 fully mutes, however I'm only using a 5.1 setup.

Mines a sp.1 so only 5.1 aswell, also get a loud hissing coming from the tweeters on the front left and right speakers, loud enough to hear when playing at low volume.Begining to think their might be something wrong

anyone from bryston have an idea

Is this something sp.1 do , would upgrading to sp1.7 cure it as its something i plan to do but not till next year some time.

I discovered tonight that if you turn the volume down so that it momentarily displays "Mute", some signal is still present on my speakers. If I press the "mute" button on the remote then I hear nothing.

As for hiss,I've always had some hiss but it disappears when more then a foot away from my speakers. Perhaps you have sensitive speakers ?

I had a hissing issue with my SP1.7 and after I send a recording of it to James they asked me to send them the unit and it came back without any hiss.

The engineer knew immediately what it was. Something about a resistor that was not supposed to be there except for testing.

Your issue might be completely different though.

Cheers

Hi All,

The hiss is digital noise and is more obvious with efficent speakers. The SP1 and SP1.7 have LOTS of gain due to the Class A amplifiers - it will swing up to 15 volts.
The SP1.7 has about an 8dB better digital noise floor than the SP1.
