ABOUT LATENCY & THIRD-PARTY ASIO DRIVERS
"Latency" is the delay between the moment when audio is generated and the moment when you actually hear it. Higher
latency means a longer delay.
The M1Active 520 USB speakers feature zero latency direct monitoring so you don't have to worry about latency when
monitoring input sources connected to the rear of the speakers. However, latency may become an issue when using software
synths and instruments.
Generally, you want to keep latency as low as possible while still allowing your equipment to operate without glitches.
Latency and buffering is usually adjusted in your software's Preferences settings.
If you still experience too much latency or "lag" when using software synths and instruments, you might want to download
one of the free and widely available ASIO (Audio Stream Input/Output) drivers from the Internet. In general, ASIO drivers
may perform better and with lower latency since they create a more efficient communication between audio devices and
software. You may download and install the free ASIO4ALL driver (PC) by visiting www.asio4all.com.
