Incidentally, has the small Yamaha no loudness circuit, what I miss in any way personally.
What I was looking for (and get)
- Stereo Amplifier
- High level inputs for CD or BlueRay player, Minidisc, cassette deck
- Simple appearance
- Small housing dimensions
- Low price
- Remote-controlled volume
For me, even buying a used device an option. Since I had received certainly more output power and features for the same money. The disadvantage of a used amplifier is unfortunately his age. Volume control catch like to scratch, contacts corrode electronic components change their properties. Exactly these things can affect the stress-free listening to music very - and then I was not exactly the point.
What are for me the highlights of the Yamaha A-S201:
- Remotely (Sleep Timer, bass, treble, volume, balance, input, Mute, Pure Direct, on-off, menu)
- No signal auto power off
- Sleep Timer
- Usable boxes Terminals
- Clean sound
- Waiver of Loudness, many buttons and frills
- Adjustable maximum volume
Incidentally, the automatic power-down is very useful, because when activated Pure Direct circuit turns off the display and only two small yellow light dots light up, which can be overlooked very quickly.
The circuit brings about an automatic shutdown of the amplifier when there is no longer signal for a certain time.
The little Yamaha has convinced me and is a tip for people on a budget that good sound is more important than many buttons.
On the subject of 4 ohm speakers:
The amplifier can drive 4 ohm speakers, just as he used with me. Handwarm at low volume.
By the way:
are 2 pairs of boxes connected with 8 Ohm and operated simultaneously, which results in a load impedance of 4 ohms. This is provided by Yamaha, so logically a single pair may be connected to 4 ohms, this must not damage the amplifier.
Boxes do not necessarily have a higher capacity than the amplifier delivers to output.
If the amplifier for the speakers too weak, for example because the speakers have a low efficiency and therefore a high power requirement, one turns to the desired volume to obtain the volume knob to continue. Device the amplifier thereby to its performance limits, to take the distortion (clipping) and especially the tweeters of the boxes may be damaged.
Of course, a significantly oversized amplifiers can also destroy the boxes. As long as you can hear in a volume in which the boxes do not distort (clang, pop, jangle ..) nothing happens. However, you can hear a very long time at high volume, the speakers may be damaged by overheating.
I myself have very compact shelf speakers never damaged with an amplifier provides 2 x 200W REAL / 300W. Very good but bookshelf speakers to a receiver with 2 x 20W / 35W damaged although these were given as 25 / 40W.
