Phonocar builds versatility and power into their OTTO reference Series amps, so they'll deliver clean, dynamic performance in any kind of system. A high-current design combines with highly efficient output transistors to allow these amps to drive low-impedance loads safely, so you can get more out of your system. Phonocar understands the importance of clean, strong amplification in producing high-quality sound. That's why OTTO amps use Phonocar's own power supply design to ensure steady output, so you'll be surrounded with all the sonic detail and impact of your favorite music. You control the variable filters and gains under an easy access concealed panel, so there's no need for extra tools to make adjustments. For multi-amp installations, you can stack OTTO Series amps vertically in a cool tower arrangement. The heavy-duty gold-plated connections are perfect for neat wire management and hidden for increased protection.
