I recently got a CP800 preamp...


My other equipment is a Mcintosh amp....the MC452 with 450 wpc.?

Speakers are Focal 1038be.... 93 db at 1 watt..... and can handle over 400 watts....


When I increase the volume on the CP800 all is fine until 0 is reached.....it gets louder...as it should.....


As I increase the volume knob past 0, it will not get any louder as I go from 0 and above on the volume control......all the way up to +14

With the specs of the speakers and the amp, it should be able hit well above 100db.....but it doesn't


Why is this ? ??

Do I have a defective unit ??

Thanks for any insight...

That might be correct for a digital input.

Does it do the same thing for an analog source?

You might also take a look at page 29-30 in your manual, discussing maximum volume setup.

I am using an analog input......
And the max volume is set at +14.....

But once I pass 0 going up.....it doesn't get any louder......

I am using a balanced XLR cable from my source to the CP800....

And the CP800 is connected to the amp with an unbalanced cable....
I should be getting XLR cables on Monday to go from the preamp to the amp....

I will see what happens when using balanced cables from preamp to amp...on Monday....

Check to see if you have a max volume limit in your setup. If yes, remove it or raise it.. The limit is designed to protect your loudspeakers from accidental damage.

The max volume on the CP800 is +14......

That is what my max volume is set at....

Thanks for the suggestion........

What wattage is the MC452 showing?

Sounds like the Classe or MC452 might be broken,
or you have a really weak analog source... you aren't using a vinyl player by chance? (Doesn't that require a phono-capable preamp?)

Are you sure your speaker isn't blown? because something is seriously wrong with this picture...

Something ain't right. With 450 wpc, the volume turned up that far, and 93dB speakers, you should be able to burst your eardrums!

That's a waste of money. Unless you've got strong electrical interference then there's all of 0 benefit to doing that.

Source is a Sony HAPZ1ES.....

I have been doing some more listening, and have discovered that when the tone control is enabled, it will not increase the volume once it gets past "0"

If the tone control is disabled, then it seems to get to higher volume levels....

I have the tone control set as follows.....

I use the bass and treble settings.... not the tilt control....

bass is set at 0 200hz ....... treble was set at +1 2100hz

maybe it is a bug in the software.....I have sent this info to Classe
