This would be an audio amplifier which can produce 50 watts of power in each of its channels (hi fi, or high fidelity, was typically one or two). Measuring 50 watts, though, is tricky, as the way audio watts have been counted has changed over the years.
A headphone amplifier can be used with a hi-fi system although is not necessary. Most hi-fi systems have the ability to have headphones directly connected through a dedicated output socket. The headphone amplifier can become useful when using high end headphones and connecting them to individual components of the hi-fi system or with many of today's portable music devices.
A high fidelity amplifier allows a stereo to push more wattage to a set of speakers. This reduces distortion and creates a cleaner sound from the stereo.
They can be anywhere true reproduction and amplification of a signal is required. They are often used in hi-fi audio applications.

To connect two home receivers with a 2.1 hi-fi amplifier and subwoofer, first, designate one receiver as the primary source. Connect the audio output of the primary receiver to the input of the 2.1 amplifier using RCA cables. Then, connect the subwoofer to the amplifier's dedicated sub output. For the second receiver, use its audio output to connect to the primary receiver's audio input if needed, or use a switch to alternate between the two receivers.
