CONFIGURATION UNDER WINDOWS

special driver installation necessary. Simply power on the speakers, connect them to your
computer's USB port and all the necessary drivers will be automatically installed.
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.
