Lavry Engineering LK-Solo Headphone Amp & Latency Killer


Lavry Engineering LK-Solo Headphone Amp & Latency Killer

The LK-Solo is a ½-rack unit which serves two functions:

1)  A high-quality headphone amplifier with super-accurate analog stepped volume control (½ dB increments).

2)  A powerful tool for 2 channel recording and overdubbing, which gives the performer 100% removal of latency from any digital recording system; while enabling the musician to independently adjust the live levels and the stereo input level.   

The LK-Solo contributes zero signal distortion and noise to the recording because each LK-Solo output connector is hardwired to the respective input connector with no electronics in the signal path between. Mixers place many additional circuits in the signal path, adding coloration, phase distortion, and noise to the signals, but the LK-Solo does not.

Converter makers have been pushed to accommodate low latency. This comes at great sacrifices in audio quality. Some IC makers go as far as providing “switchable” digital filters (lower latency at lower quality or higher latency for higher quality). The LK-Solo enables use of quality converters without latency concerns. Freedom from latency also enables use of large buffers, recording at any sample frequency, many plugins in series, and even additional hardware in the signal path, with no limits.

The user interface of the LK-Solo is designed for easy workflow. The learning curve of operation is trivial, and the hookup is negligible (requiring 4 additional cables and no additional hardware).
