The ProSpec™ 1U4M4S single rack space mixer has 4 mono mic/line input channels and 4 stereo line input channels designed for use in mono, stereo, and LCR.
This mixer has 4 channels of professional quality Burr-Brown mic preamps, and 4 balanced stereo line input channels. An individual solo switch is on each mono and stereo input channel. Input channels are individually assignable to left-right or mono (center) mix bus.
Mono input channels have level and pan controls, 48V phantom power, high pass filter, polarity reverse, and assignment switches. Stereo input channels have level and balance controls, mute, polarity reverse, and assignment switches. Mono input channels use Neutrik XLR/1/4" combo connectors and TRS insert points, while stereo inputs use individual high quality 1/4" balanced left and right input connectors.
Monitor headphone level control with 1/4" and 1/8" headphone connectors and rear panel APB mixer link connector. Other features include individual left right and mono metering, and low phase-shift.
