SM Pro Audio has announced MPatch 2.1, a passive volume controller/monitor switcher.

Designed to provide true passive analog control over studio monitoring systems—thereby eliminating the loss of bit-depth associated with digital attenuation—the third-generation MPatch 2.1 features dual inputs with independent volume controls, a newly-designed master attenuator utilizing state-of-the-art 0.5% tolerance SMD resistors, a headphone output with separate volume control, and a subwoofer output with variable crossover. Both balanced combination XLR / 1/4” TRS and unbalanced RCA inputs are provided, with input selection, mute, stereo/mono summing operation, and subwoofer in/out selectable from the front panel.
