Yamaha A-S301 overview

  • 1Description

Expand your listening horizons with the black A-S301 Integrated Amplifier from Yamaha. Featuring up to 70W per channel of RMS power at 6 ohms, this amp is equipped with digital inputs for connecting devices like televisions and Blu-ray/DVD players. It offers dual stereo outputs, giving you the ability to power two sets of speakers in different rooms and switch between them, or have them both playing at the same time. To increase the bass output of your sound system, there's also a terminal for connecting a subwoofer.

To reduce distortion and degradation and produce the cleanest possible sound, the A-S301 employs Pure Direct Mode. Activated via a button on the front of the unit, this mode causes input signals to bypass unused circuits and cuts off those circuits' power supply. To further ensure quality sound, the amplifier's continuously variable loudness control allows you to balance low and high frequency sounds so you can hear a full tonal range at any volume.

This Yamaha amplifier was built with energy efficiency in mind, and uses a power management system to switch itself to idle mode when not in use. The A-S301's internal circuitry mirrors itself symmetrically to produce higher signal purity and lower degradation. The chassis is reinforced with a solid center bar to reduce vibration and features a brushed aluminum front panel and knobs. The system comes with a remote control for easy operation.

Pure Direct Mode
The Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp and the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.
Continuously Variable Loudness Control
The A-S301 features an analog loudness control on the front panel, which lets you adjust the loudness effect as desired. Separate from the overall volume, this controls the balance of the low- and high-frequency sounds, providing full tonal range at any volume level, compensating for the natural loss in the human ear of high and low frequencies at soft levels.
Direct Symmetrical Design
This amplifier's left and right channels are organized in a straight, symmetrical layout for limiting distortion and increasing signal purity.
Anti-Resonance Chassis
The base of the A-S301's chassis is reinforced with a solid center bar to increase rigidity support and vibration damping, which limits resonance.
Dual System Capable
You can connect two separate speaker systems in different rooms and switch between them or have them both play at the same time by switching the dial on the front of the unit.
Phono MM Terminal
You can connect a turntable with an MM phono cartridge to play vinyl records, allowing you to enjoy records in addition to modern media sources.
Auto Power Standby Function
This amplifier puts itself into standby mode when it detects that it hasn't been used in approximately 8 hours, minimizing power consumption.
Remote Control
Control your music from afar with the included remote, finished to match the design of the amplifier. The remote comes with batteries and can also be used to control a Yamaha CD player.
Connection for Bluetooth Wireless Adapter
With the optional YBA-11 Bluetooth Wireless Adapter, you'll be able to stream music wirelessly from a Bluetooth-capable mobile phone or a PC to the network receiver. This amplifier features a DC-out connection on the rear panel to power the adapter.
Rotary Encoder Input Selector
The rotary encoder makes it quick and easy to select input sources, and the LEDs clearly show which source is selected so you can easily switch between them, even in a dark room.

    Yamaha A-S301 reviews

    A-S301 Integrated Amplifier (Black) is rated 4.7 out of 5 by 10.
    Rated 5 out of 5 by from who listens to the radio anymore? imho, you should skip the old 'receiver' and upgrade to a new Integrated Amplifier like this Yamaha unit. When shopping to replace my receiver i stumbled across an article on cnet about integrated amps. After spending a couple hours learning about these devices and finding a unit with an a/b speaker switch (for my speakers in the backyard), i selected this Yamaha unit.Never going back to a Receiver...easy to use, great sound (thd about 0.019), performs exactly as expected. great value too. Only 'con' is that it should allow for independent audio sources for each speaker set.

    Rated 4 out of 5 by from Excellent budget choice The yamaha as-301 is an awesome amplifier for people with low budget. The phono input is decent and much better than other amplifiers in the same price range, many inout choices although no hdmi. In terms of power the yamaha can easily drive demanding speakers like Elac B6 or wharfdales upscale models. Perfect choice for beginners but good also for more demanding listeners.

    Rated 5 out of 5 by from Very Satisfied This amplifier delivers the great sonic performance promised in the specifications at a very reasonable price. The construction is top-notch with a clean internal layout and controls that feel substantial and durable. The aluminum front panel is also a plus, compared to some competitors that use plastic. The only tiny criticism I have is that I think the power pilot and two function selector LEDs should be more prominent, as it is hard to tell that the unit is on in normal room light unless you're looking at eye-level.

    Rated 5 out of 5 by from Great amp, great new features I upgraded from a Yamaha AX470 to the new A-S301, basically the same power plant but with the new refinements, a subwoofer connection, and Bluetooth capability. Same quality and price point.

    Rated 4 out of 5 by from Cheapest integrated amp with optical input Product works as described.This is the cheapest integrated amp I could find with optical input for TV with only optical & headphone outputs. Has shared optical/coaxial inputs. Unit is larger than I would like. Buttons on remote are tiny. Also hard to read what is selected on face-plate of unit. Sound quality is ok.

    Rated 5 out of 5 by from Very good stereo amp and a great value I was fortunate enough to purchase this amp on sale (249.95) just before Christmas and am very pleased with it. The audio performance is very good and it had all the features I needed including a phono input, several RCA audio inputs, digital inputs, a nice DAC and a very good headphone stage . I'm using a 20+ year old Philips CD player and playing FLAC audio files through 80's era Boston Acoustics A70 speakers. The amp has brought new life to these older components and delivers a terrific audio experience. The remote control is very solid and will operate other Yamaha components.� I do wish it had better visual options on the front panel to indicate volume level and input selection when in use. There are very small lights for each input, but they are almost impossible to read across a room. The volume dial does have a black line on it, but it is impossible to see from more than a few away.� Overall I'm very pleased with the A-S301. Great stereo performance at a great price. Paired with a good set of speakers or headphones, it provides a terrific audio experience.

    Rated 5 out of 5 by from Solid amp, a bit bulky This is a really good amp, I have it driving two JBL wall mount speakers and I get rich sound in all ranges. The different inputs are super convenient, including the USB power port available where I'm using a Chromecast audio. The only downside is that it's a bit bulkier than I expected, it is certainly the center of attention on my living room rack.

    Rated 4 out of 5 by from Simple answer for a simple need... This replaced, in essence, a Marantz 1122DC integrated amp. Similar power specs plus it has sub-woofer output, phono input and digital inputs. So far, works real well. Running Polk powered sub with JBL Control 5's as satellites. Also have second set of speakers running off of B outputs. Didn't need AV capability so I'm set. Kept at 4 stars cause I'm still breaking it in. We'll see what happens.
