The Markacoustic AH 250 is a compact and lightweight head for acoustic instruments. Connect it to your preferred cabinet/s, or use it as a preamp without a speaker—just take a line from the XLR out and set your master volume to zero. The analog amp is 150W @ 8 ohms or 250W @ 4 ohms, and offers two preamp channels (one 1/4” jack and one XLR/1/4” combo jack with switchable 48V phantom power). Anti-feedback and phase reverse controls allow you to capture the true essence of your acoustic sound while enjoying serious headroom.
