Headphones are simple pieces of audio equipment. You plug them in, turn your device on and music comes through. Most people wouldn’t expect them to need any special equipment to work. However, what if you don’t just want to listen to your music? What if you truly want to hear it? In that instance you’ll need something to increase the level of signal that reaches your ears. A headphone amp is the answer and it will drive the signal from your music player, increasing the volume and detail in the audio signal and enhancing your listening experience.

The HA4 Compact 4-Channel Stereo Headphone Amplifier from CAD provides high-quality audio in a compact and durable package. The CAD HA4 features a 6.3mm (1/4″) TRS stereo input along with four discrete output channels each utilising 6.3mm (1/4″) TRS stereo headphone jacks. An RCA (L+R female) to 6.3mm (1/4″) TRS stereo adaptor is also included.

Each of the 4 output channels has its own volume control so that listeners may set their preferred listening level without affecting others.

The CAD HA4 operates on 240VAC-12VDC power via the included adapter.
