Enhance Audio During Your Jam Sessions With Quad Amplifiers

When you're jamming and want to make music sound better, an electronic quad amplifier can help. This device changes how noises are transmitted through audio equipment by modifying a signal's power, current, or voltage. These devices are available in new and used condition on eBay.

What are the different quad amplifier options?

Many brands design a variety of amplifiers that have a unique purpose. When audio amplifiers are built, sound engineers use hardware to give each product a unique processing capability. Before amplifiers are marketed, they're categorized; the main categories are power amplifiers and weak-signal amplifiers. Among these designs, you'll find

  • Integrated amplifiers: Within an integrated amplifier, there is a power amp and a preamplifier. A traditional amplifier also separated components.
  • Phono pre-amp: This amp can enhance sounds from a turntable. As a phono pre-amp intensifies music, the hardware makes strategic audio adjustments to change amplification levels that impact a signal.
  • Power amplifier: A power amplifier generates a low signal. You can connect this amplifier to a guitar or a radio.
  • Preamp/processor: AV preamp hardware is designed for home theatre equipment. This accessory has audio/video switching capabilities.
What are common quad amp features?

Amplifier features vary based on the manufacturer and the hardware. The most common feature options for general amplifier products are

  • Bluetooth: Bluetooth connects an audio device to an amplifier without wires. Many amplifiers by reputable brands are designed with Bluetooth 4.0.
  • DAC capability: DAC stands for digital-to-analogue; this technology is usually featured in a converter. You can use this amp feature to convert an audio signal that's transmitted to a headphone amp.
  • Remote hardware: An amplifier remote is a piece of hardware that connects to sound equipment. Most remotes have a solid base housing that's attached to a red plug and a white plug.
What are the audio output options?

The audio outputs transmit audio signals from an amplifier. You'll find many amplifier products with an output for

  • DIN hardware: In the 1970s, DIN connectors were invented. These connectors interact with amplifiers and produce audio signals. The top standard for circular connectors is DIN 41524.
  • Preamp hardware: A preamp input port connects an amplifier to a preamp. This input can help you eliminate noise and distortion.
  • Stereo L/R RCA hardware: This input transmits a stereo audio signal. It connects an amp to sound equipment that has left and right stereo speakers.
What are the audio input options?

Input ports move audio signals to an amplifier and are found on the rear housing panel. Most audio amplifiers that are designed with output ports have the same input ports. The most common input options are DIN ports and Stereo L/R ports.
