Yamaha A-S1200 – this is modern technological solutions in a “retro-wrap” for immersing the listener in the golden age of Hi-Fi. This is evident both in the design of the case with old-style tone and balance controls, and in the needle indicators with soft LED lighting.
Yamaha A-S1200 – integrated amplifier
Although this model is the lower in the lineup, it contains a powerful toroidal transformer. Paired with symmetrical amplifiers on discrete components, it provides output power up to 160 W at 4 Ohms. As well as accurate and emotional sound transmission.
The Direct mode is activated by moving the BASS and TREBLE controls to the zero position. Thus, the signal will bypass the tone control circuit. On the back of the A-S1200 amplifier case are located:
- 4 line inputs and 1 output.
- Phono corrector input for MM/MC cartridges.
- Pre-out output.
- Main in input for connecting an external preamplifier.
- Four pairs of speaker terminals.
- Trigger input for automatic power on/off synchronization with other compatible components.
- Auto-off mode switch.
Yamaha paid great attention to optimizing the construction itself. A well-thought-out mechanical grounding concept helps eliminate unwanted vibrations. The strength is also enhanced by powerful silver-plated metal legs. The original design of the speaker terminals, cut from brass, ensures reliability and ease of connection.

The price of the Yamaha A-S1200 integrated amplifier is not child’s play (around $2000). But the sound quality is at a very decent level, even for a budget solution. As one of the authors noted on social networks – this is the younger device in the senior class of Hi-Fi equipment. There is something in this phrase.
