Looking for a portable headphone amplifier that easily integrates with your home setup? The HA204p portable headphone amp from Rolls is an ideal choice. It combines lightweight portability and flexible power options with four output channels, independent volume controls (up to 20dB of clean gain), and a broad frequency response that’s suitable for any audio situation. Sweetwater audio enthusiasts really appreciate the HA204p’s compact design, which ensures a convenient fit into almost any size bag and stores easily at home.
Portable amplification
The HA204p is easy to use for mobile monitoring on the go. Roughly eight hours of mobile use is possible with a single 9-volt battery — the perfect battery life for audio techs and mobile needs. A 9-volt power setup also means fewer batteries to carry, a feature that results in less bag clutter and a more organized rig. The HA204p’s lightweight design clocks in at just under one pound, and user-friendly 1/8-inch outputs mean there’s no need to keep track of multiple quarter-inch adapters just to use your device.
Custom monitoring with full frequency response
The HA204p allows efficient customizable monitoring for up to four users at once. Users can easily tailor volume to their liking via four independent rotary controls and the box delivers up to 20dB of clean gain per channel. An impressive 15 to 35kHz response range is suitable for all audio genres whether you’re dealing with detailed low end, ample treble, or both.
Pick your power source
The HA204p is a great amplifier choice for those with limited space who need a multi-use device. It can also be powered via electrical outlet (in addition to the 9-volt battery option). The box includes a Rolls AC wall adapter for indoor use, and its sleek design is easy to integrate into any desktop setup.
