Yamaha A-S201 Integrated Amplifier
220,00 €
The Yamaha A-S201 is an integrated stereo amplifier for a two-channel home audio system. Its MM phono input allows direct connection of a turntable fitted with an MM cartridge. Two sets of binding-post speaker terminals and a selector make it easy to choose the speaker system in use. Pure Direct mode provides a direct signal-path option, while the headphone output is intended for private listening. A remote control is included.
The Yamaha A-S201 integrated amplifier is designed for a two-channel home audio system. It features an MM phono input, a CD input, a headphone output and two sets of speaker terminals. The Pure Direct mode provides a direct signal-path option.
Who is this amplifier for?
This integrated stereo amplifier can serve as the central component of a system, connecting separate audio sources to passive speakers. Its two channels are intended for a conventional left- and right-speaker arrangement.
The built-in MM input is useful for vinyl listeners. A dedicated headphone output supports private listening. A remote control is included, allowing the main functions to be operated from the listening position.
Connecting audio sources
Use the MM phono input for a turntable fitted with an MM cartridge. If the turntable outputs a line-level signal, connect it to the CD input instead. This is particularly important when using a turntable with its built-in phono preamplifier switched on.
The CD input has a sensitivity of 500 mV and an impedance of 47 kilohms. The REC Out output sends an audio signal to a recording device. A separate output on the front panel is provided for headphones.
The binding-post speaker terminals hold speaker cable securely. Two terminal sets allow two speaker systems to be connected, with the active system selected using the speaker selector. If both systems are used at the same time, the impedance of both systems determines the combined load presented to the amplifier.
Controls and initial setup
First select the connected audio source and the required speaker system. Begin with the volume set low, then raise it gradually. This makes it easier to assess differences in signal level between sources safely.
Pure Direct mode lets you select a direct signal path.
Understanding the power ratings
The minimum RMS output power is 100 W + 100 W into 8 ohms. This figure is measured across the 40 Hz-20 kHz frequency range at 0.2% THD.
Maximum output power for the European version is specified as 115 W + 115 W into 4 ohms. This measurement is taken at 1 kHz with 0.7% THD. The two results should not be compared directly because the load and measurement conditions are different.
Dynamic power figures are provided for several impedances. They describe conditional dynamic performance rather than continuous output power.
Positioning on an equipment shelf
The enclosure is 435 mm wide and 333 mm deep, while the amplifier weighs 6.7 kg. Choose a stable shelf and leave enough room behind the unit for the speaker cables. Do not cover the amplifier or trap cables between the enclosure and the furniture.

FAQ
Can I connect a turntable without a separate phono preamplifier?
Yes, provided that the turntable uses an MM cartridge. Connect it to the MM input. An MC cartridge requires a separate phono preamplifier designed for its signal.
Which input should I use for a turntable with a built-in phono preamplifier?
Use the CD input when the turntable is set to output a line-level signal. That signal should not be amplified again through the MM input.
What do the two sets of speaker terminals mean?
Two speaker systems can be connected to the amplifier and selected using the speaker selector. When both systems are used together, their impedances must be considered as the amplifier’s combined load.
Is the 115 W rating higher than the 100 W RMS output?
These ratings were measured under different conditions. Speaker impedance, frequency range and permitted distortion differ, so a direct comparison would be inaccurate.
When should I use Pure Direct mode?
During initial setup, compare Pure Direct with the standard mode using the same recording at the same volume. This will help you decide which setting is better suited to the particular source.
How much space does the amplifier require?
The shelf must accommodate the 435 × 141 × 333 mm enclosure and support its 6.7 kg weight. Leave additional space behind the rear panel for cables.
