4. Setup
4.1 Tqegħid
Poġġi l- amplifier on a sturdy, flat surface with adequate space around it for proper ventilation. Avoid enclosed cabinets or areas where heat can accumulate. Do not place other components directly on top of the amplifier's ventilation grilles.
4.2 Konnessjonijiet
Qabel ma tagħmel xi konnessjonijiet, kun żgur li amplifier is turned off and unplugged from the AC power outlet. Use high-quality cables for optimal audio performance.
Figure 2: Rear panel of the Yamaha A-S1100 Integrated Amplifier. This image illustrates the various input and output terminals, including speaker terminals, RCA inputs, and power input.
4.2.1 Konnessjonijiet tal-Ispeaker
- The A-S1100 features two sets of speaker terminals (A and B) for connecting up to two pairs of speakers.
- Connect your speakers to the SPEAKER A or SPEAKER B terminals. Ensure correct polarity (+ to + and - to -) for each speaker.
- Il- amplifier supports speaker impedances of 4 ohms or higher. When using both A and B speakers simultaneously, ensure each speaker has an impedance of 8 ohms or higher.
- Use banana plugs or bare wire for connections. Tighten the terminals securely.
4.2.2 Konnessjonijiet tal-Input tal-Awdjo
- CD, TUNER, LINE 1, LINE 2: Connect your audio sources (e.g., CD player, tuner, network player) to these RCA input jacks.
- PHONO (MM/MC): Connect a turntable to these inputs. Use the MM/MC selector switch to match your phono cartridge type (Moving Magnet or Moving Coil). Ensure the ground wire from your turntable is connected to the GND terminal on the amplifier to reduce hum.
- MAIN IN: These inputs bypass the preamplifier section, allowing you to connect an external preamplifier jew proċessur.
4.2.3 Konnessjonijiet tal-Output tal-Awdjo
- REC OUT: Connect to the recording input of a recording device (e.g., tape deck).
- PRE-ĦRUĠ: Qabbad ma' provvista ta' enerġija separata amplifier or a subwoofer with built-in amplifikazzjoni.
4.2.4 Remote and Trigger Connections
- REMOTE IN/OUT: For connecting to other Yamaha components for synchronized operation.
- TRIGGER IN/OUT: For power synchronization with other compatible components.
4.2.5 Konnessjoni tal-Enerġija AC
After all other connections are made, connect the supplied power cord to the AC IN terminal on the rear panel and then to a wall outlet.
