Again, HiFi Amplifiers are the back-bone of any Home Audio or AV Stereo System. However, Home Hi Fi Power / Stereo Amps were not always digital as they predominantly are today. Analog music / audio signals have been electronically amplified since the 1920s. Back then, engineers used vacuum tubes to boost the analog signal to a level at which it could power a speaker. Subsequently, the use of transistors to amplify an audio signal became the standard method. Both of these methods produce a lot of heat and if cheap components were used (to cut costs), there was a significant signal distortion and thus loss of signal quality. Then came audio on a Digital CD, which although had a digital signal, the audio signal had to be fed through an Analog Amplifier to be heard. Hence, the next logical progressive step, The Digital Amplifier. This new Power Amp allowed the transmission of the stereo signal in a digital form without a conversion back to an analog signal (if the amplifier has digital inputs), which created a signal loss and hence quality loss.
These Home Stereo Power Amps provide most of the connections to the rest of your system, often including your television. Moreover, they often include a Preamp that controls which audio/video source is selected, processes the incoming sound signals, and distributes audio to the separate channels. Many are fully capable of running a whole house audio system, as well as home theater systems, without the need for additional Power Amps. Certain models have multiple channel / zone outputs for whole house audio. As stated on other pages, if the unit does not have multi channel capability, one will have to worry about low impedance when connecting multiple speaker pairs to one zone. When a multi zone system is wired off one channel or zone, one would have to use an impedance matching/protecting device. Connecting impedance matching volume controls in line from the power source will achieve this, as will wiring to a multi zone speaker selectors with impedance protection.

General & Install Necessities, or GIN Electronics, is so named because we deal in Custom Install Products, and G.I.N. is a clever acronym for General & Install Necessities. Besides, the owner loves Martinis!
We began selling over the internet in the year 2000. In the huge world of the internet, a little unknown company like GIN Electronics is easily lost. Hence, we treat our customers with great respect and give them great customer service and thus we have been getting many customers by word of mouth from our satisfied customers. We also, for customer security, have implemented Paypal as a means of payment. Paypal is probably the safest and most trusted means of payment on the internet.
The long-term goal for GIN Electronics is of course to stay in business and prepare for the future. However, a home with a good AudioVideo System is a harmonious home, and we plan on spreading the wealth of music and theater as long as we have customers that want to enjoy them as much as we do.
Here at GIN, we will point you in the correct direction and put together a system that fits your needs and budget. Once we have completed a win-win transaction, we can all relax and enjoy a dry martini. Good Day & Cheers!
