3 INTRODUCTION
The PASSIVE-1 expands on the core audio control capabilities of the venerable M-Patch 2, with
four selectable signal sources, USB I/O, talkback with built-in condenser microphone, ducking,
mute, mono summing and dual independent headphone amplifiers. Featuring entirely passive
operation from signal input to output, the PASSIVE-1 delivers the purest signal path possible,
giving you clean, transparent sound with no added audio artifacts or coloration.
PASSIVE-1 allows you to connect multiple input signals, route them to various destinations, and
control their levels via rotary volume attenuators. The PASSIVE-1 an ideal centerpiece for monitor
control in home, professional, and project studio applications. As it is a passive attenuator, we
recommend you set the volume knob in the maximum position, and attenuate the volume down to
the desired listening level.
