In terms of where Tortuga Audio is headed next by way of major product development, our primary near term focus is on finishing development of our balanced passive preamp for release in the Q4 2013. We are calling this preamp the LDR3B.
The twin beating hearts of the LDR3B will be a pair of LDR3x boards in a Master/Slave configuration. We are currently separately marketing the LDR3x board to the DIY community. Demand has been surprisingly high and initial user reports have been very very positive.
One aspect of the design which is now essentially final is the input/output configuration. The "3" in the LDR3B means there will be both 3 inputs along with 3 outputs. An earlier rear panel layout is shown below. Since this graphic was made, we've shifted the all the panel holes so they line up vertically with each other rather than offset as shown. And although shown in gray, all metal will be brushed black anodized with laser etched light lettering.
2 of the 3 inputs will be balanced and 1 will be single ended. We've had several customers ask for the option of being able to accommodate at least one single ended (RCA) input as well as one single ended output (for subwoofer). Internally, the one unbalanced input is converted to a balanced signal via transformer. This way all 3 inputs will be attenuated identically regardless of which input/type is currently selected.
The selected input, regardless of type, will be available on all 3 outputs; 2 balanced and 1 single ended. The balanced output will be run through a transformer to convert it down to an unbalanced single ended output.
Below is the latest overview of the LDR3B enclosure. It's grown in width from earlier prototypes. Current nominal dimensions are 8.5" wide, 8" deep by 3" high. This will be the new "look" of all our products going forward. All metal panels will be brushed black anodized aluminum and the sides will be carbonized 3 layer bamboo. Trying to think outside the black metal box just a bit. We plan on retaining our signature Fender Telecaster knurled knob. The LDR3B will also have a visual display module.
Pricing has not been finalized.
