Behringer ULTRATONE K1800FX

Behringer ULTRATONE K1800FX amplifiers have clean sound, all-in-one unit useful for keyboard or vocal use. Built in mixer and effects, along with EQ that has a feedback detector. I use the K1800FX as a vocal performance PA system, playing music tracks through a line level channel and plugging my microphone into the mic level input of the mixer and adding reverb from the effects function. It sounds very good and can achieve about 90dB SPL in a medium sized venue. It is a bit heavy at 44 pounds. Power rating is in peak power, so the 180 watts is not RMS. Only one of the four mixer channels has a microphone level XLR input. No EQ on individual mixer channels. The reverb and delay effects are good, but chorus and flanging are a bit weak.
