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 First HiFi System introduced in 1920 We introduced numerous HiFi components (turntables, FM/AM tuners, integrated amplifiers, preamplifiers, power amplifiers and speakers) in 1955 - 1965. Natural Sound Speaker Series introduced in 1967 NS-20 Monitor Speaker CA-1000 Integrated Amplifier Featuring A-Class operation, the CA-1000 set the standard for integrated amplifiers.
◆ Full floating and balanced circuit design achieves for the first time the full potential of analogue amplification An entirely new floating and balanced power amp achieves complete symmetry and permits full balanced transmission (amplification) from the input jack to just before the speaker jack ◆ Full-stage balanced signal transmission The world’s first integrated amp to offer full stage balanced transmission, combining high power output with good sound texture and outstanding S/N performance ◆ Floatin

Connections ■ Connecting the speakers ■ Connecting the banana plug (Except for Europe models) 1 Remove approximately 10 mm (0.4 in) of insulation from the end of each speaker cable and twist the exposed wires of the cable together to prevent short circuits. First, tighten the knob and then insert the banana plug into the end of the corresponding terminal. 10 mm (0.4 in) Banana plug 2 Unscrew the knob and then insert the bare wire into the hole.
■ Bi-wire connection ■ Connecting to the CD BAL jacks 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. This split connects the mid and high frequency drivers to one set of terminals and the low frequency driver to the other pair. Connect your CD player with the XLR balanced output jacks.
Connections ■ VOLTAGE SELECTOR (Asia and General models only) Caution The VOLTAGE SELECTOR on the rear panel of this unit must be set for your local voltage BEFORE plugging the power cable into the AC wall outlet. Improper setting of the VOLTAGE SELECTOR may cause damage to this unit and create a potential fire hazard. Rotate the VOLTAGE SELECTOR clockwise or counterclockwise to the correct position using a straight slot screwdriver. Voltages are as follows: ........................
