JBL Professional CSM 14 - Commercial 4x1 mixer with priority, phantom power and CSR-V remote control
The JBL Professional CSM 14 is a 4-input, 1-output commercial mixer designed for background/foreground music, public address, and announcement systems in retail, hospitality, education, and corporate environments. Housed in a 1U half-width , fanless chassis, it features independent bass/treble controls for the output, contact priority , and VOX ducking on channel 1 to automatically override announcements. It offers balanced mic/line inputs on Euroblock connectors and stereo RCA inputs (summed to mono) for power sources. 27V phantom power allows for the use of condenser microphones, and a 70Hz high-pass filter helps protect ceiling speakers on 70/100V networks when the CSM 14 is used with external amplifiers. It includes a balanced line output and an RJ-45 port for remote CSR-V volume control via Cat 5 cable. Its included rack kit allows for clean mounting: as a 1U half-width, in pairs of two units, or with the supplied brackets.
