The USA-made Rolls Bellari HA543 is a stereo headphone amplifier offering low-distortion amplification with minimal phase shift for musicians, producers, and engineers in home and project studios. It accepts a stereo source via balanced XLR or unbalanced RCA input jacks, and drives 3.5mm and 1/4" stereo headphone outputs. The stereo RCA output serves as a pass-thru, allowing the input to be connected to a monitor controller, home receiver, or audio recorder.
A single knob provides up to 20 dB of gain for the headphone jacks, which can be disabled via the mute switch. The Enhance function changes the tone sent to the headphone outputs while leaving the RCA output flat. The HA543 is powered via the included 15 VDC power supply, and features a power switch with an LED indicator.
