Rolls HA543 Headphone Amplifier

If you mix, master, or simply love audio, you need the Rolls HA543 headphone amplifier. When you mix you want to hear what's really there. No coloration, enhanced bass, or "air" added to the audio, just the audio. And sometimes, you want to sit back and get lost in the presentation. More dominant vocals, open, splashy cymbals, and more powerful, articulated bass. The HA543 gives you both with the flick of a switch. In standard mode, the amp puts out what you put in, a flat, unaltered reproduction of the input source. When you hit the Enhance switch, internal coloration circuits are activated to process the input signal and make it sparkle. The HA543 makes good headphones sound great, and great headphones sound amazing. The amp accommodates 1/4" and 3.5mm headphone connections and features a master volume and mute switch in addition to the Enhance button. It accepts XLR and RCA stereo inputs and includes pass-thru stereo RCA outputs for connection to external gear. Hear your music the way you want to hear it with the HA543.
