In many modern systems "maxing out" the amplifier's sensitivity controls is the only practical solution. If using the power amp loop out isn't the right way to do it, you can always just use two RCA splitters (one on a left output from the pre-amp, and one on a right output) and run cables to both power amps from a single set of outputs on the pre-amp. The unit ships with the gain set in the middle position. Rated Power, specified in Watts (W) Input sensitivity, specified in Volts (V) Consider, as an example, the Bryston C-Series amplifiers and an older Rotel RB-890 amplifier. A pre-assembled amplifier board or module is a great alternative to starting from scratch. This is more commonly used with IC power amplifiers where it is desired to have a system capable of generating large power into the rated load impedance (i. The input stage board consists of many smaller circuits to do things like providing crossover functions, making bridging for more power possible, providing gain control, and blocking ground loop noise. Transformers are the most expensive components in an amplifier, so manufacturers save money by using 'off the shelf' units available on the market. The amplifier is very loud and has a lot of inputs as well as a tuner. If the Distribution Amp is installed between the Preamp, and the Preamps power source, the Distribution Amp will block the voltage that needs to get to the Preamp. You use the pre-amp to very carefully define what the input is. In an older, more audiophile stereo system, the functions of a stereo receiver can be split into three separate components. When choosing an amplifier, look out for these specifications: 1. Not only that, but a tube preamp/solid-state power amp will give you a hybrid sound of the best of both worlds – the warmth of tubes and the punch and dynamics of solid-state.
