The latency through our DSP engine is somewhere in the neighborhood of 1ms. So if you have your audio output device, i.e. a Digi playback output device connected to the analog inputs of our monitors, sound travels from your audio application to your audio hardware to our analog inputs and once it reaches our DSP board, 1ms later you hear it.
Each Equator monitor comes with Equator Control. An application that allows you access to muting, soloing, EQ, phase control, among other features. This communication is handled through USB. Our monitors show up as a USB composite device and the faster your USB ports, the less latency for COM communication. So if you have a USB 1.0 post on your computer and an 800mHz processor, latency would be higher than a USB 2.0 port and dual 1 Gig processors. This only affects communication at the control level of the features within our application. Again, muting, soloing, selecting speakers, etc...
Playback from your audio application and through your audio output hardware has its own latency values that our monitors are not affected by. When audio hits our monitors via our analog inputs, 1ms later you hear it. The latency for COM communication to our monitors from your computers USB port via our Equator Control app is dependent on the host computers speed. i.e. USB 1 or 2, processor speed, the amount of RAM, etc...
You will not need to adjust synch when working to picture any differently when using our monitors than with any other monitoring system.
