The LK-1 Latency Killer is for overdubbing work – latency free real time monitoring of DAW.
Unlike all other products on the market, the Latency Killer offers zero latency. In addition it contributes absolutely no sonic alteration or coloration for the recorded signals.
Latency can trip up musicians by causing them discomfort. This negatively impacts their performances. In order to deal with latency, the musicians are forced to make timing adjustments in their heads. An observer may not be able to tell if even a relatively large timing delay was intended by the musician. Meanwhile, the musician may be struggling because what they hear is not as intended.
Latency comes from time delays due to electronics in the signal path between the singer/instrument and the headphones. In many systems, the time delay is due to both computers and converters. While some designs bypass the computer, they offer only a partial solution - the latency due to the converters remains a problem. Further efforts to reduce latency are based on reducing the converter time delays.
Manufacturers of recent converter ICs offer a switchable choice between lower latency with poorer audio performance, and higher latency with better audio performance. The pursuit of any further reductions in latency – while desirable – is limited by the already compromised audio conversion quality.
By employing an ANALOG approach, the Lavry Latency Killer™ allows musicians to hear themselves in real-time during recording and overdubbing even with systems that utilize higher-quality components. Delay is no longer a concern.
The LK-1 is “inserted” into your existing signal paths. The signals from the sources to the ADCs are routed through the LK-1. The LK-1 inputs are shorted to the outputs by hardwired connections, resulting in no delay and no degradation in the recorded signal paths.
Two other analog inputs accept a stereo-mix from the DAW. The live sound monitoring (the cause of latency) is muted in the DAW computer. The LK-1 replaces that signal with the original source before the DAW AD conversion – providing a latency free mix.
A large rotary knob and lighted buttons control the analog mix to the headphones. The headphone mix consists of 1 to 2 channels of live sound, the signal from the DAW, and 1 to 2 optional effects units (typically DDL and reverb). The rotary knob is circled by indicator LEDs, providing visual feedback for volume and pan.
A pair of high-quality headphone amplifiers with independent volume control accommodates different headphones and ear sensitivity – enhancing collaboration. This is especially helpful when the musician and the DAW operator are not the same person.
The learning curve is minimal, the setup is easy, and the unit retains all settings when powered down. The user can also store and recall 2 settings from non-volatile memory.
