UCAB Stereo Amplifier Amplificateur Stéréo OWNER’S MANUAL MODE D’EMPLOI
HiFi Began with Yamaha Yamaha’s involvement with and passion for music goes back more than a century, to when we built our first reed organ in 1887. Now we are the world’s leading producer of pianos and other musical instruments, and are involved with music in many other ways as well. We manufacture professional recording equipment, we design concert halls and we assist artists at concerts with set up and sound tuning. This knowledge and experience benefits our production of audio components in many ways.
Excellence in Audio Achievement 1922: We introduced a high-quality handwound phonograph. Since 1955, we have released many HiFi components, including turntables, tuners, integrated amplifiers, control amplifiers, power amplifiers and speakers.

Remove approximately 10 mm (0.
■ Bi-wire connection The bi-wire connection separates the woofer from the combined midrange and tweeter section. A bi-wire compatible speaker has four binding post terminals. These two sets of terminals allow the speaker to be split into two independent sections. With these connections, the mid and high frequency drivers are connected to one set of terminals and the low frequency driver to another set of terminals.
