HiFi Began with Yamaha

Yamahas 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 worlds 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 1954. 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.

3 PHONES jack Outputs audio for private listening with headphones.

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.

4 TRIM Adjusts the volume level when headphones are plugged in to avoid sudden changes in volume. Choices: 6 dB, 0 dB, +6 dB, +12 dB

5 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.

If you use two sets (A and B), the impedance of each speaker must be 8 or higher.

6 BASS Increases or decreases the low frequency response. The 0 position produces a flat response. Control range: 10 dB to +10 dB

7 TREBLE Increases or decreases the high frequency response. The 0 position produces a flat response. Control range: 10 dB to +10 dB

When both the BASS and TREBLE controls are set to the 0 position, audio signal bypasses the tone control circuitry.

The BASS and TREBLE controls do not affect the signals input at the MAIN DIRECT jacks and signals output at the REC OUT jacks.

8 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.

The BALANCE control does not affect the signals input at the MAIN DIRECT jacks and signals output at the REC OUT jacks.

9 PHONO Selects the type of magnetic cartridge of the turntable connected to the PHONO jacks on the rear panel. Press upward to the MM position when the connected

turntable has a moving magnet (MM) cartridge. Press downward to the MC position when the

connected turntable has a moving coil (MC) cartridge. When you replace the cartridge, be sure to turn off this

unit.

Connections In this section, you will make connections between A-S2000, speakers, and source components.

Connections

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 owners manual for each of your components.

Use RCA unbalanced cables to connect other components except speakers. Use male XLR balanced cables to connect a CD player with XLR balanced output jacks to the CD BAL jacks of this unit.

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 record players.

Because the power amplifier of A-S2000 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 terminal. Connect it to the PRE OUT jacks of this unit.

Connecting the speakers

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.

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

3 Tighten the knob.

Connecting the banana plug (Except for Europe models)

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

Connecting the Y-shaped lug

1 Unscrew the knob and then sandwich the Y- shaped lug between the ring part and base.

2 Tighten the knob.

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. This split connects the mid and high frequency drivers to one set of terminals and the low frequency driver to the other pair.

To use the bi-wire connections, the impedance of each speaker must be 8 or higher.

Remove the shorting bars or bridges to separate the LPF (low pass filter) and HPF (high pass filter) crossovers.

To use the bi-wire connections, switch the SPEAKERS selector to the A+B BI-WIRING position.

Connecting to the CD BAL jacks Connect your CD player with the XLR balanced output jacks. The pin assignments for these jacks are shown below. Refer to the owners manual supplied with your CD player and verify that its XLR balanced output jacks are compatible with the pin assignments.

When connecting, be sure to match the pins and insert the connector of the male XLR balanced cable until you hear a click. When disconnecting, pull out the male XLR balanced cable while holding down the lever of the CD BAL jacks.

To use the XLR balanced connection, you must switch the INPUT selector on the front panel to the CD BAL position.
