When you wish to directly monitor the signal at the inputs of the Quattro, you
may engage the “Direct Monitor” switch for Input 1/2 and/or Input 3/4 by
pressing and locking it to the “in” position. Doing so connects the input (1/2 or
3/4) directly to the corresponding output, bypassing the computer and software.
You may choose to use the Direct Monitoring option to avoid any latency
inherent in your music recording system. Using the ASIO drivers and an ASIO
capable music program with the Quattro will allow you to monitor your
recording source with reduced latency, while using the Sound Manager can
introduce latency that is generally considered unacceptable. The Quattro’s Direct
Monitor option will allow you to monitor your recording source with zero
latency
