World-class analog-to-digital conversion for audiophiles.

The DVA A2D is a high performance analog-to-digital converter (ADC) that lets you listen to analog sources with digital preamplifiers* that don’t have built-in ADCs, including our own. It also provides a significant upgrade for digital preamplifiers that have built-in ADCs.

The DVA A2D has two selectable sets of analog RCA inputs and one isolated coaxial S/PDIF output. It was designed specifically for use with digital preamplifiers, so it doesn’t include the added cost of a USB output for computer use. Simply plug the DVA A2D's coaxial S/PDIF output into an available coaxial input on your digital preamplifier and enjoy incredible analog audio.

Unlike the ADC circuits found in many digital preamplifiers, the DVA A2D is built to true audiophile standards. It uses converters typically found in high-end studio equipment, but with input conditioning circuits that retain the full signal purity from consumer-type line-level input signals.

You’ll be shocked at how little you give away when processing a signal through a competently designed analog-to-digital converter. We were! In fact, we are willing to put the combination of the DVA A2D and our DVA Digital Preamplifier up against the finest analog preamplifiers. It’s that good.

Whether you want to use analog sources with our DVA Digital Preamplifier or upgrade the from the ADC in your current digital preamplifier, you won't be disappointed with what the DVA A2D will do for your system.

*"Digital preamplifier" is our term for any DAC with a variable output level that can be connected directly to a power amplifier.

Layout and power supply

The DVA A2D is built into a compact 7" x 5" x 2.5" chassis. The power transformer is supplied as a separate “wall wart”, so no significant AC noise is brought inside the chassis. The internal power supplies use heavily filtered linear regulators for extremely low power supply noise.

Specifications

Inputs: Two stereo RCA pairs for consumer line-level signals.
Input impedance: 20 kΩ
Maximum input before clipping: 1.4 Vzero-to-peak. Larger signals can be attenuated via the front panel LEVEL control.
Output: Coaxial S/PDIF, transformer isolated.
Sample rate: 96 kHz default. Internally configurable to 48, 96, or 192 kHz.
Digital resolution: 24 bits.
Power: 16VAC, 200mA

Great pants but buy one size up in the waist. They are well made, comfortable, and good looking. They are Dickies brand what more needs to be said.

order 3 or 4 inches up than your usual waist, run very small in waist
Color: Charcoal, Size: 33W x 30L
arrived with dirt on the bottom legs but amazon helped with that. anyway I weigh 115 lbs and am 5'8 and I am a woman. I know that Dickies these days run super small for their size, so it sounds insane but order up 4 inches than your normal waist size, then run small in the waist and they will shrink a size with a few washings. I ordered a 33 waist and they did shrink probably a size in one wash lol! they are still a bit loose in the waist but not big and I know with a couple more washings they will be just right. I do not like anything skinny fit or with no give. but yah, I love the charcoal gray color, one of my favorite colors, much cooler than plain black. I normally enjoy the Dickies shorts but with these forty something degree afternoons these are my new go tos. I am not a jeans person and I sure as hell with not be wearing pajama pants out in public like these dang younger adults lately.

Perfect fit every time
Color: Silver, Size: 30W x 30L
These original 874’s are the real deal. Stocked up during the sale and got them for my husband. He loves all the colors and the durability of these pants is incredible. He still has some from 14 years ago! But he wanted a few new ones- and they had more colors so I stocked up and surprised him when I told him how much they cost during the sale. These pants never wrinkle. I wash them hot and air dry- no wrinkling or shrinking. They look great. They’re sewn to perfection. The quality is there and has been for years, a reason my husband only wears these. Quality, value, durability, style, fit. Great for all seasons, they’re not too heavy or too light. Great functionality- pockets for everything . Great even in summer - they are very breathable. Perfect fit every time. Great for heavy road construction or just going for a hike. Highly recommend!
