Introduction - Lavry Latency Killer LK-SOLO Owner's Manual

Introduction

Introduction
The Lavry Latency Killer – Solo (LK-Solo) is an extremely high-quality headphone amplifier capable of
effortlessly driving a wide range of headphones from a stereo source, with precise and resettable control of
the volume in half dB steps.
In addition, the LK-Solo can provide a latency-free mix of previously recorded material and "live" signals
during recording and overdubbing with any computer-based Digital Audio Workstation (DAW). The musician
can adjust the DAW and his/her own sound levels separately, a useful tool for real-time applications.
By mixing signals in Analog rather than Digital, the unit negates delay from conversion and digital processing
while using the included high-
quality headphone outputs.
By employing a passive hard-
wired signal path from the
analog source inputs to the
outputs used to feed the DAW,
the LK-Solo accomplishes this
without introducing any
audible or measurable
distortion, coloration, or noise
to the recorded signal. This
also means that the LK-Solo
Volume settings only impact
the headphone Cue-Mix, and
thus have no effect on the
recorded signal.
Figure 1 – Headphone Latency in Digital Recording
All digital audio recording systems introduce time delay between signal arrival and playback. In computer
based DAW systems this can be a combination of converter delay, and computer processing.
To reduce latency, some systems utilize a digital mixer between the ADC output and the DAC input and mute
the recorded signals in the DAW. This effectively bypasses the computer's contribution to the latency.
However, the converter delay remains.
Unlike these "low latency" systems, the Lavry LK-Solo completely bypasses the entire latency problem (both
the converter delay and the computer delay). It does so by mixing the live sound signal (prior to conversion)
with the DAW output.
In this manual, the term "live signal" refers to the signal to be recorded. This signal is fed to the LK-Solo, and
then from LK-Solo to the recording input normally used for this purpose. The LK-Solo is compatible with both
line and professional signal levels.
