Lavry Engineering AD11

The Lavry Engineering AD11 stereo A to D converter offers USB connectivity, making it ideal for everything from archival to recording. The AD11 includes built-in microphone preamplifiers with phantom power, large wide-range LED meters, and Lavry’s exclusive digital tape saturation emulation (“Soft Saturation”) for hotter recordings with peak level control.

All settings are controllable from the AD11’s front panel using a system similar to that of the companion D to A converter- the DA11. Building on Lavry’s long established reputation of making the most accurate AD converters available, the AD11’s no-compromise design offers substantial value at an affordable price. The AD11 combines musicality and functionality in a single unit that exceeds other manufacturer’s stand-alone units in this price range.

The USB output is available in parallel with both XLR and RCA AES/SPDIF digital audio outputs, so more than one recording or monitoring device can be fed directly from the AD converter. For dual-mono operation, the MicPre or +4dBu/-10dBV line level input function and phantom power are selectable on each channel, as well as Soft Saturation. Like the previous LavryBlack model AD10, the Lavry Engineering AD11 has “XLR-TRS combo jacks” for the analog inputs. When a balanced or unbalanced ¼” plug is inserted, 12 dB’s of fixed gain is automatically added to the front panel adjustable gain, to boost “-10dBV” consumer level signals to “+4dBu” professional level.

Front panel line level input gain adjustment is available for each channel in 12 precise one dB steps. Additional gain in the range of 20 to 65 dB’s is provided for balanced low-impedance sources (typically microphone). This makes it possible to record the “direct” signal from a guitar effects unit or keyboard at the same time as a vocal mic, with no more than the AD11 and a laptop! In addition to “dual monaural” recording; extremely precise matching between channels makes the Lavry Engineering AD11 equally well suited to high-quality stereo Mastering applications or “true” stereo recording. Whether it’s home, on location, or professional studio- the AD11 is the right tool for the job!

Archiving Vinyl

Anyone who is serious about archiving their Vinyl collection understands it is a time consuming process and that only an exceptional AD converter will yield results that make it worthwhile. The ability to accept -10 consumer level inputs common to most HiFi preamplifiers and phono preamplifiers and easily adjust the gain for level variations between disks makes the AD10 (AD11) an excellent choice for this application.

Lavry Engineering AD11 Key Features

  • Recording at 44.1, 48, 88.2 or 96 kHz with 24 bit word length
  • Super-stable internal clock
