Description

The Latency Killer (LK-1) is a specialty product; it does not fit into any standard category. It is for overdubbing work – latency-free real-time monitoring of DAW.

The basic concept is based on muting the playback of the recorded channel (on the DAW), and replacing it with the music signal before the AD conversion.

Such signal replacement is not new, it has been done in studios utilizing mixers, headphone amplifiers, and various gear for steering analog signals. The LK-1 offers a completely integrated solution.

The LK-1 offers a big advantage over mixers: There is no signal alteration and no coloration because the LK-1 output is hardwired to the input (no electronics in the signal path). Mixers place many additional circuits in the signal path.

Converter makers have been pushed to accommodate low latency. This comes at great sacrifices in audio quality. This is the tail wagging the dog. Some IC makers go as far as providing “switchable” digital filters (lower latency at lower quality or higher latency for higher quality). The LK-1 enables use of quality converters (no latency concerns).

Freedom from latency concerns enables the use of large buffers, many plugins in series, and even additional hardware in the signal path, with no limits.

The user interface of the Latency Killer is designed for easy workflow. The learning curve is minimal. The hookup (with any digital system)  is easy and requires no additional hardware (other than a few cables)

The rotary settings are precise and repeatable. 3dB coarse and 1/2dB fine steps for volume and thirteen positions for pan. The unit also offers 2 complete user-defined presets.

Two separate headphone amplifiers (with individual volume control) accommodate different headphones and ear sensitivity. This is especially helpful when the musician and the DAW operator are not the same person.

The LK-1 also offers hookup to effect units (DDL and reverb are often used in overdubbing to help the musician hear themselves above the recorded music tracks). The effects channels only modify what is heard through the headphones and leave no marks on the recording tracks. However, there are optional feed-through outputs for effects to be recorded on separate tracks.

THD+N (DISTORTIONS PLUS NOISE)

THD+N @ +24dBu input, +18dBu output unless noted:

Main Input to ADC Loop Output Too low to measure
DAC Monitor Input to DAC Loop Output Too low to measure
Main Input to Headphone Output -95dB re 18dBu
DAC Monitor Input to Headphone Output -90dB re 12dBu*
Effects Return to Headphone Output -90dB re 12dBu*
Main Input to Effects Send Output -92dB re +18dBu

 

*+12dBu results when only one input is driven with +24dBu

 


 

DYNAMIC RANGE

Input connected & muted, re+18dBu output level unless noted:

Main Input to ADC Loop Output >130dB re+24dBu
DAC Monitor Input to DAC Loop Output >130dB re+24dBu
Main Input to Headphone Output >102dB
DA Monitor Input to Headphone Output >99dB
Effects Return to Headphone Output >99dB
Main Input to Effects Send Output >112dB
