Initial pics of the LDR3.V2

Early pics of the LDR3.V2 enclosure. These show the silver face before clear anodizing which will even out and tone down the brightness of the aluminum somewhat. While not obvious in the pics, there are dual blue displays behind the dark inlay which are invisible when the unit is off.

$995 pre-order special through Jan 5th. $1195 thereafter.

More info on the LDR3.V2 here: LDR3.V2 Passive Preamp | Tortuga Audio

For balanced operation of the LDR3x V2.1, I guess we need to preorder 2x? Any special cabling between them?

Thanks

Hi Do,

Yes, 2 LDR3x.V2.1 boards are needed for balanced audio attenuation. One serves as the master and the 2nd is designated as the slave. They communicate via a simple 4 wire cable that connects to a 4 pin header on either board. 2 of the those wires carry serial data and the other 2 handle hand-shaking. This cable is provided with each pair of boards and is approximately 7 inches long which if fine if both boards are located next to each other. The boards can also be located remotely from each other in which case I recommend a higher quality shielded 4+ wire cable that you'll need to equip with female square pin connectors on either end. We don't supply such longer cables but it's an easy DIY item to cobble together.

Best,
Morten

Morten,

I assume that detailed instructions on converting the controller board into a functioning preamp module (e.g. hooking up the encoder, connecting the DMI, paring with the remote, initial software set up of the board etc) will be provided to the GB purchaser of the board?

Yes indeed. Although it will need to be updated for the V2.1 board, you can review existing documentation on our website here: Product Documentation | Tortuga Audio

Morten,

Ooops! I forgot to ask the "last question" - I am using an Apple remote for something else, can I assume that this remote can also be used with your controller board?

Thanks!

Yes, if you have an existing Apple remote it can be paired with the LDR3x board. The Apple remote must be the current silver metal remote, not the older white plastic remote.

However, using one remote to control both the LDR3x and some other device can be problematic since both devices will respond to the remote if they are close enough to each other and both connected to power.

Morten,

I was trying to get to your website to place an order for the pre-amp kit but Firefox blocked it, claiming your website is unsafe??? Can you take a look please.

Although the website is actually fully operational, google informed us earlier today that the site has been hacked with malware. Hence the warning you saw from the browser. :eek:

We're actively working to have the malware removed and also set up enhanced malware monitoring/protection on the server. It may take a day or two to get this resolved given that it's Christmas Eve. I'll post an update as soon as we have it all cleaned up.

Sorry to the hassle. Will get this fixed soon. :santa3:

Website is cleaned up and secured.

Merry Christmas everyone. We've had our website cleaned from top to bottom using the services of securi.net, have changed all the passwords etc., and have stood up an enhanced server firewall on our hosted web server. So we are up and running malware free and fully secured.

Enjoy the holidays! :santa3:

I read that you had planned to do a software version for 10K input impedance. Is it coming soon ? thks ;)
Click to expand...

The release of the V2.1 version of our LDR3x Passive Preamp Controller Board includes firmware that allows the user to adjust the input impedance. There are 5 different input impedance settings that can each be defined by the user between 1k and 99k. Setting #1 comes set at 20k by default.

For example, you could set up 5 input impedance settings at say 5k, 10k 20k, 50k and 90k and switch between them "live" while playing music to determine which sounds optimal for your system.

My own impressions from trying this in our test rig is once the impedance is "high enough", raising it higher doesn't necessarily provide any additional benefits.

All Tortuga Audio LDR preamp products shipped on or after Jan 5th, 2015 include this feature. Owners of the earlier V2 board will soon be able to update their firmware to include this feature as well.

Cheers,
Morten

$199 for LDR3x.V2.1 Preamp Controller Board

If you've been thinking about building your own passive preamp, the $199 Tortuga Audio Passive Preamp Controller is arguably the best value in DIY audio today.

If you haven't listened to music through an LDR preamp you haven't heard your music! Yes, it's that good!

Bunch of hype you say? Check out what our customers are saying: Product Reviews | Tortuga Audio

Our latest version V2.1 of the LDR3x series is our best yet with increased precision auto-calibration of the LDRs for improved sound stage and stereo imaging. The V2.1 also allows you adjust the input impedance between 1k and 99k to optimize your system.

$199 - LDR3x.V2.1 Passive Preamp Controller | Tortuga Audio

Want to go DIY but not interested in sourcing everything yourself? Why not go for a comprehensive kit!

$695 - LDR3.V2K Passive Preamp Kit | Tortuga Audio
