Manufacturer's Description
When it comes to amplifiers, Pioneer's line up offers sound options that make music sound better than ever. Pioneer amplifiers are what the dreams of audio lovers are made from - innovative high performance components with extra features and additional connections to all types of speakers and home entertainment systems. Amplification without distortion and stable sound localization leads to what you want: pure sound.

The A-109 is a 40-Watt integrated amplifier that adds a stabilizer for the transformer and chassis. And its symmetrical design results in excellent stereo imagery. The A-109 is among those Pioneer amps to feature the Direct Energy MOS FET transistor directly linked to the speaker output. Efficient input signal transmission with minimum distortion requires the signal path to be as short as possible. The highly efficient Direct Energy MOS FET allowed Pioneer to develop its Advanced Direct Connection, with a shorter signal path and ground line and Symmetrical Construction. This combination ensures that left and right channels are clearly separated and have the same impedance, giving ideal stereo reproduction with identical sound quality. These two design concepts ensure more stable stereo sound localization and a rich sound field.

Customer Reviews

broke after 5 months
I was really pleased when it arrived and I worked great for the first 5 months. It was carefully used and wired up properly and broke last week. Amazon do not accept returns after 1 month and the Pioneer returns department is abysmal so despite it being under warranty I cannot return it. I wouldn't bother buying this product!

Mostly harmless
I use this as a PA amplifier in small halls, mostly fed from a very simple battery-powered mixer and a radio mic. In this capacity it works well, but it would be nice if the main unit incorporated a means of mixing or adding more than one input rather than merely switching from one to the other. An odd idiosyncrasy is that a sudden large spike to the input (e.g. pulling out an audio plug) can cause the front end to go into some kind of oscillation, knocking out the sound completely until the unit is switched off and on again (and there is a nine second delay before it comes back on). I returned mine for servicing in an attempt to solve this problem but the engineers were unable to reproduce the fault. It's fairly rare but disastrous when it happens. In normal use the unit is absolutely fine and good value for the money.

Great amp!
If you want a really great amplifier but you're a student, or you don't want to spend a fortune on an amplifier, than this is the amp for you! It gives a rich and clear sound. And no one can beat the price!
The only downside is the lack of support for a second pair of speakers, if you don't mind this, then go for it!
