I suspect you are misreading the spec. I expect that is
the 'nominal' load but I'd be VERY surprised if it can't
drive a lower impedance. Without schematics to hand I
couldn't give a precise figure.


For openers, the title "QUAD CD" *does not describe a single piece of
equipment, or even a single family of related products. There are at two
families of Quad CD players, *the 67 family and the 99 family. * The Quad 99
series players further compound the situation by having two different sets
of outputs with very difference performance specs.

I suspect that Jute is basing his alleged specification on the standard IHFM
line level load which includes a 10K resistive component. If that's the case
then he's still in error because the proper way to address that load is with
a device that expects to see 10K or *less*.


You're a blustering idiot, Krueger. This is from the QUAD official
literature of the CD66 and it states "10K minimum*: " Audio Output:
2Vrms maximum. 300mV on normal progamme material. Minimum load
impedance 10kR."

What part of "minimum load impedance 10KR" do you fail to understand,
Krueger?

We have three idiots pontificating about a simple number, which all
three have got it wrong -- but not one of them has bothered to look it
up! But meaningwhile these three morons are smacking their chops in
glee that someone else got it "wrong." How childish. No wonder these
newsgroups remain in intensive care.

Jute, it is true that getting sucked into responding to one of your posts
takes a certain amount of either optimism (that you would have finally grown
a brain) or idiocy (expecting you to change your behavior).

This is from the QUAD
official literature of the CD66 and it states "10K
minimum*: " Audio Output: 2Vrms maximum. 300mV on normal
progamme material. Minimum load impedance 10kR."


Jute, I see that you've already assigned fault to me for not being able to
read your mind and somehow know which Quad CD player you were whining about.

Far be it from you to take responsibility for making a unnecessarily vague
post.

I am surprised that someone who purports to design & build amplifiers etc.
would have to ask such a basic question. This is electronics 101.......

Here's a fourth clown who just can't resist pursing his lips and
passing a spiteful judgement.

I've had that Rane note since it first appeared. To be "helpful" in
"Electronics 101" it should show how the numbers he mentions are
derived. It doesn't. Read my question, then read the Rane note again.

Good point. Every Jute amplifier schematic I've seen looked like it was
copied from someplace.

Jute says he's read it, which only makes him look even more strange.

Only two cycles of messages from an innocent question to the resident

attack on the poster. Is anyone surprised that i treat this malicious
scum with open contempt? -- Andre Jute

Jute,

Just to delurk for a moment.....

Why not just wire the frigging resistors in and see what it sounds like ?

Would be much quicker than messing about in here.

I was deliberately making a simple talking point. That has succeeded.
There was also the salutary secondary effect of proving once more that
the self-appointed gatekeepers (the jerks I refer to collectively as
"the scum") keep out newbies by making any discussion personally
unpleasant. Who'd want to ask a question if you were treated as I've
been treated by Poopie Stevenson, "Eiron", that New Zealand jerk
Coatham (who actually had the effrontery to label his abuse as
"helpful"!), and the ever-wretched Krueger?

Trust me Andre, we save our *special treatment* for know-it-alls like you.

We give far better treatment to those who we recognize as being fellow
members of the human race. ;-)
