CA31 is a three channel amplifier with a nominal output of 2 x 65 Watts + 1 x 170 Watts (1 x 280 Watts in 2 ohm).
- Built-in high-pass, low-pass and subsonic filters.
- Protection circuits shut down the amplifier in the event of overloads.
- Phase shift control on sub channel
- High level input with auto start.
- The perfect amplifier for a standard installation with a front system in stereo and a subwoofer in the back.
- RMS output power @ 13,8 V, 20Hz – 20 kHz
