Hey Guys,

Just wanted to say USPS shipping is always available at HeadRoom upon customer request for small, fairly inexpensive items like earpads, eartips, accessories and interconnect cabling... You'll just have to call us during business hours to place the USPS-delivery order since our primitive online order cart does not specify FedEX or USPS (soon!) delivery as of yet.... Typical USPS mailing charges within the continental USA average about $5 bucks!

I lied. I remember exactly where I read that. And the manual still says what I thought it did.

What's up with this? Dual mono or no?

Howdy Thread,

...Hmm, i think that's the spec description for the Micro Amp / Ultra Micro Amp topologies -- which do indeed have full dual mono designs all the way back to the power supply & a DC coupled signal path from input to output.

The Micro DAC devices do not share this design.

I will look into our HeadRoom Micro manual copywriting asap to ensure the verbiage is correct!...

Yeah, sounds like you have an issue with the manual, then. Because it does, indeed, read

Code:
Full dual mono design all the way back to the power supply
Right underneath

Code:
Micro DAC & Ultra Micro DAC Common Features

Looks like you need to update your web site too:

The Micro DAC - HeadRoom - Right Between Your Ears

Ultra Micro DAC - HeadRoom - Right Between Your Ears

Both pages include:

• Full dual mono design all the way back to the power supply

Okie dokie, I'm going to do this post in a couple of steps because I'm still figuring some stuff out.

I think the problem might be a misunderstanding of terms here at HeadRoom.

My understanding is that dual-mono means that the left and right channel are completely electrically separate all the way back to the power cord. This means that to be truly dual-mono you have to have two power supply transformers, and that the two sides don't touch each other till you get back to the primary side of the transformers.

So the statement "Full dual mono design all the way back to the power supply" is logically inconsistent with my vocabulary. The product does however maintain completly separate paths for left and right signals, supply voltages, and grounds which do come together at the supply.

I know that some manufacturers will advertise dual-mono when there is one power transformer with one primary winding and two secondary windings, or when there is one transformer and rough supply, but separate regulation for the left and right side.

I'll stop there and ask the question: What do you think Dual-Mono means?

While youz guyz answer that, I'll rummage through the schematics and refresh my memory of what, exactly, is in each.

Well, my RPX-33 says dualmono right on the front, and it has two discrete power supplies... so I guess I would agree with you, Tyll, that dual mono should mean everything is separate from the power cord entering the device to the actual output jack.

So it seems your copy really meant "dual mono from the power supply to the output" or something...

It seems to me that you might be able to use the words dual mono somehow in your literature via marketing fudge, but it must be qualified, and putting the word "full" would simply be untrue from my standpoint...

I have listened to this units and they sound amazing. So as far as sound, does it matter what we call it? Not in my opinion.

However to appease the righteous then I would agree w/ the 1st definition used by Tyll.
