CAD Audio CAD Astatic MX12S 12-Channel Stereo Rack Mount Mixer

The MX12S packs 12 input channels into a 1U rack mixer: six XLR/1/4-inch combo inputs with mic, line and phantom-power selector switches per channel, plus six mono (three stereo pairs) RCA inputs for media players or other line-level sources. That combination covers a house of worship or conference room running several microphones alongside background music or video playback.

A 3-band EQ with cut/boost on high, mid and low frequencies shapes the overall mix, and a channel-1-priority control automatically ducks other sources when a designated mic (often the primary announcer) is live. It runs on AC power or 24V DC, with 18-21V phantom power available for condenser microphones.
