รายละเอียดสินค้า :

The Markacoustic AH250 is a compact and lightweight tube amp head for acoustic instruments. Connect it to your preferred cabinets, 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.

The Markacoustic AH 250 acoustic head is a great choice for anyone who needs a small, light and portable amp head to amplify acoustic instruments. It can be connected to your preferred cabinet/s, or directly to a mixer via the line out (you can use it as a preamp without connecting it to a speaker—just set your master volume to zero).

The amplifier head is powered by an analog amp (150W @ 8 Ohms/250W @ 4 Ohms) and features our own custom-designed digital power supply circuitry. There are two preamp channels, with a 1/4" jack input for Channel 1, and an XLR/1/4" combo input for Channel 2, with switchable 48V phantom power.

Anti-feedback and phase reverse controls allow you to easily manage feedback and phase problems and capture the true essence of your acoustic sound while giving you serious headroom.
