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 320 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.
