Yorkville Sound CA4 Coliseum Installation Amplifier

The CA4 is a rack-mountable power amplifier for retail, restaurant, office, and worship applications. It features five input channels which can be assigned to four output zones. Channels 1 - 4 have mic / line inputs with switchable phantom power, and channel 5 has stereo aux inputs that are summed to mono. Each output zone has 4Ω, 70V, and 100V terminals so it's easy to integrate with a range of speaker systems. The media module features a Bluetooth receiver and USB-A port, for playback from wireless sources or flash drives.

The mixer offers 2-band EQ on all input channels, and reverb on inputs 1 and 2. Output zones have a switchable Outdoor voicing, which limits low-frequency bandwidth to enhance clarity and projection. Powerful, flexible, and intuitive, the CA4 sets a new standard for Yorkville zone amplifiers. Need something more streamlined? Check out the classic CA1.
