3INTRODUCTION
!
Designed to provide the lowest noise operation possible in an active monitor controller, the
ACTIVE-1 is ideal for applications where both signal attenuation and boost is needed.
Building on the feature set of the PASSIVE-1, the ACTIVE-1 also includes LED level-metering and
convenient switch selectable +4dBu/-10dBV input stage operation. The ACTIVE-1 is automatically
recognized by the host computer as a USB device for easy DAW recording and playback via the
on-board USB I/O.
It allows you to connect multiple input signals, route them to various destinations, and control their
levels. The ACTIVE-1 is an ideal centerpiece for monitor control in home, professional, and project
studio applications.

discussion in the studio without having to change the position of the volume knob.
5.4 Mute
Activate this switch to mute the signal from the outputs.

audio signal into a monophonic signal, which helps to check for any phase cancellation issues in
the stereo signal.

turn adjusts the level of the audio going through the device.
