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. We introduced our first HiFi (High Fidelity) turntable in 1955. Thereafter we were one of the first to offer mass-produced, high quality audio equipment,

and introduced many legendary stereo components.

We hope you enjoy the genuine HiFi experience of Yamaha Natural Sound.

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.

Outputs audio for private listening with headphones.

Note

When headphones are plugged in:

Both speaker sets connected to the SPEAKERS L/R CH A and B terminals are turned off.

No signals are output at the PRE OUT jacks, while signals are output at the REC jacks.

You cannot select MAIN DIRECT as the input source.

If headphones are plugged into the PHONES jack while MAIN DIRECT is selected as the input source, no audio is output at the PHONES jack. Use the headphones jack of the preamplifier connected to the MAIN IN jacks.

4 SPEAKERS

Turns on or off the speaker set connected to the SPEAKERS L/R CH A and/or B terminals on the rear panel.

Switch to the OFF position to turn off both speaker sets.

Switch to the A or B position to turn on the speaker set connected to the SPEAKERS L/R CH A or B terminals.

Switch to the A+B BI-WIRING position to turn on both speaker sets.

Caution

If you use two sets (A and B), the impedance of each speaker must be 8 or higher. When only using one set of speakers (A or B), use speakers with an impedance of 4 or higher.

6 TREBLE

Increases or decreases the high frequency response. The center position produces a flat response.

Control range: –9 dB to +9 dB

y

When both the BASS and TREBLE controls are set to the center position, audio signal bypasses the tone control circuitry.

7 BALANCE

Adjusts the audio output balance of the left and right speakers to compensate for sound imbalances caused by speaker locations or listening room conditions.

Note

The BALANCE control does not affect the signals input at the MAIN IN jacks (INPUT selector: MAIN DIRECT) and signals output at the REC OUT jacks.

Note

The BASS and TREBLE controls do not affect the signals input at the MAIN IN jacks (INPUT selector: MAIN DIRECT) and signals output at the REC OUT jacks.

Caution

If you use two sets (A and B), the impedance of each speaker must be 8 or higher. When only using one set of speakers (A or B), use speakers with an impedance of 4 or higher.

Do not let the bare speaker wires touch each other or do not let them touch any metal part of this unit. This could damage this unit and/or the speakers.

All connections must be correct: L (left) to L, R (right) to R, “+” to “+”, and “–” to “–”. If the connections are faulty, no sound will be heard from the speakers, and if the polarity of the speaker connections is incorrect, the sound will be unnatural and lack bass. Also, refer to the owner’s manual for each of your components.

Connect your turntable to the GND terminal to reduce noise in the signal. However, you may hear less noise without the connection to the GND terminal for some turntables.

Caution

Because the power amplifier of A-S1000 is of the floating balanced type, the following types of connections are not possible:

Connecting with the left channel “–” terminal and the right channel “–” terminal as well as “+” terminals (Fig. 1).

Deliberately connecting with the left/right channel “–” terminals and metal part on the rear panel of this unit, as well as accidentally touching them.

Connecting with the left channel “–” terminal and the right channel “–” terminal inverted (cross connection, Fig. 2).

Do not connect your active subwoofer to the SPEAKERS L/R CH terminal. Connect it to the PRE OUT jacks of this unit.

Caution

If you use two sets (A and B), the impedance of each speaker must be 8 or higher. When only using one set of speakers (A or B), use speakers with an impedance of 4 or higher.

Connecting the speakers

1Remove 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.

10 mm (0.4 in)

2Unscrew the knob and then insert the bare wire into the hole.

3 Tighten the knob.

Connecting the speakers using the banana plug

(Except for Europe models)

First, tighten the knob and then insert the banana plug into the end of the corresponding terminal.

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.
