A Living Tradition in Sound A piano comes into this world through the perfect synergy of advanced technical skill and artistry. Such a piano can create sound that truly reflects the player’s feelings. The final stage in piano production is called “voicing”. It is here that the instrument is given its soul.
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 the full potential of analogue amplification An entirely new floating and balanced power amplifier 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 integrated amplifier offers full stage balanced transmission, combining high power output with good sound texture and outstanding S/N performance.

Connections ■ Connecting the speakers ■ Connecting the banana plug (Except for Europe models) 1 Remove approximately 10 mm 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 Banana plug 2 Unscrew the knob and then insert the bare wire into the hole. Hole for banana plug: 5.5 mm dia.
■ Bi-wire connection ■ Connecting the power cable 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.
Connections ■ Connecting to the BAL 1/BAL 2 jacks Connect your CD player or network player with the XLR balanced output jacks. Set the ATTENUATOR selector and PHASE selector located below the BAL 1 or BAL 2 jacks according to the component to be connected. ATTENUATOR selector: Select the allowable input level for the XLR balanced input jacks. If sound from the connected component is distorted, set the ATTENUATOR selector to ATT. (-6 dB).
■ Operating this unit from another room If you connect an infrared receiver and transmitter to the REMOTE IN/OUT jacks of this unit, you can operate the unit and/or external component using the supplied remote control located in another room. Infrared receiver REMOTE IN OUT When you have another Yamaha component supporting remote connection, as this unit does, an infrared transmitter is not necessary.
Connections ■ Connecting a component supporting the trigger function such as a Yamaha AV receiver The operations of this unit can be controlled in synchronization with the operations of the connected component, such as a Yamaha AV receiver (power ON/ STANDBY or MAIN DIRECT input selection).

Troubleshooting Refer to the chart below if this unit does not function properly. If the problem you are experiencing is not listed below or if the instructions below do not help, turn off this unit, disconnect the power cable, and contact the nearest authorized Yamaha dealer or service center. Problem Cause Remedy See page The power cable is not connected to the AC IN inlet on the rear panel or not plugged in the AC wall outlet. Connect the power cable firmly.
Problem Cause Remedy See page The sound from the component connected to the BAL 1/BAL 2 jacks is degraded. The sound level is higher than the maximum input level for the XLR balanced input jacks. If the output level of the connected component is double, set the ATTENUATOR selector located below the input jacks to ATT. (-6 dB). Bass is not spatial when BAL 1/BAL 2 (balanced input) is selected. The polarity is incorrect. Select the correct polarity with the PHASE selector.
