AB Integrated Amplifier OWNER’S MANUAL
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. CA-1000 NS-20 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.

Controls and functions In this chapter, you will learn the controls and functions of A-S1100.
CONTROLS AND FUNCTIONS Controls and functions ■ Front panel (pages 6 to 9) 1 2 3 4 5 1 STANDBY/ON, OFF switch Turns on or off this unit. STANDBY/ON (upper position): With this switch position, pressing the p AMP key on the remote control toggles the power between STANDBY and ON. OFF (lower position): The power of this unit is turned off. Notes • When you turn on this unit, it will take a few seconds before this unit can reproduce sound.
5 METER selector Switches the meter function as follows: OFF: Turns off the meter and the illumination. PEAK: The meter functions as a peak level meter. The peak level meter shows a momentarily highest audio output level. VU: The meter functions as a VU (Volume Unit) level meter. The VU level meter shows an effective audio output value that is similar to human senses. 6 Meters (LEFT/RIGHT) Show the audio output level of the left (LEFT) and right (RIGHT) channels in VU or PEAK meter mode.
Controls and functions ■ Front panel (pages 6 to 9) A 0 0 Remote control sensor Receives signals from the remote control. A INPUT selector/indicator Selects the input source. The indicator of the input source selected with the INPUT selector lights. The audio signals of the selected input source are also output at the LINE 2 REC jacks. MAIN DIRECT: Selects the component connected to the MAIN IN jacks.
B C D B AUDIO MUTE switch Press downward to reduce the current volume level by approximately 20 dB. Press again to restore the audio output to the previous volume level. y You can also rotate the VOLUME control on the front panel or press the VOLUME + or – key on the remote control to resume the audio output. C AUDIO MUTE indicator Lights when the mute function is turned on with the AUDIO MUTE switch. D VOLUME control Controls the volume level.
Controls and functions ■ Rear panel 1 2 3 See page 16 for connection information. 1 PRE OUT jacks y • The PRE OUT jacks output the same channel signal as the SPEAKERS L/R CH terminals. • When you connect a stereo cable to the PRE OUT jacks to drive the speakers using an external amplifier, it is not necessary to use the SPEAKERS L/R CH terminals. • The signal output at the PRE OUT jacks are affected by the BASS and TREBLE control settings.
A B 2 C E D F 0 MAIN IN jacks Use these jacks to connect an external component equipped with a volume control. y When you select MAIN DIRECT as the input source, the volume level is fixed. Adjust the volume level using the volume control on the external amplifier connected to the MAIN IN jacks when you select MAIN DIRECT as the input source. For the connection to the MAIN IN jacks, see pages 16 and 17.
Controls and functions ■ Remote control 1 Infrared signal transmitter Outputs infrared control signals. 1 AMP OPEN/CLOSE 2 p AMP key Turns this unit ON or switches it to STANDBY mode. For details on STANDBY mode, see “Front panel” (page 6). CD 2 3 LINE 1 LINE 2 PHONO MAIN DIRECT CD TUNER 3 Input select keys Selects the input source. The audio signals of the selected input source are output at the LINE 2 REC jacks.
5 CD player control keys Control various functions of Yamaha CD player. Refer to the owner’s manual of your CD player for details. p CD key: Turns the CD player ON or switches it to STANDBY mode. OPEN/CLOSE key: Opens/closes the disc tray of the CD player. (Play): Starts playback. (Pause): Pauses playback. Press the or to resume playback. (Stop): Stops playback. / (Skip): Skips to the next track, or skips back to the beginning of the current track. SOURCE: Selects the source to be played on the CD player.
Controls and functions ■ Installing batteries in the remote control 1 Remove the battery compartment cover. 2 Insert the two batteries (AAA, R03, UM-4) according to the polarity markings (+ and –) on the inside of the battery compartment. ■ Operating range of the remote control Approximately 6 m (20 ft) 30 30 1 2 y The remote control transmits a directional infrared beam. Be sure to aim the remote control directly at the remote control sensor on the front panel of this unit during operation.
Connections In this section, you will make connections between A-S1100, speakers, and source components.
Connections Speakers A (R channel) CD player with RCA jacks Tuner + + - - Ground Speakers B (R channel) Turntable BD player, etc. Notes • 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 “–”.
External amplifier or active subwoofer CD recorder, tape deck, etc. Speakers A (L channel) Preamplifier, AV receiver, etc. - + – + Speakers B (L channel) Notes Fig. 1 Fig. 2 + L + L – – – – R R + + • Because the power amplifier of A-S1100 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).
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: 3.95 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 ■ 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. Rear panel of A-S1100 TRIGGER IN REMOTE IN SYSTEM CONNECTOR OUT ■ Remote connection between Yamaha components When you have another Yamaha component supporting remote connection, as this unit does, an infrared transmitter is not necessary.
■ 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).
