A confident final check before the cart.

Rolls HA43 Pro — compact 4-channel headphone amplifier for studio and live sound applications, distributing a single stereo mix to four independent headphone outputs with individual volume control. The HA43 Pro accepts a stereo line input via RCA or 1/4-inch jacks and feeds it simultaneously to four 1/4-inch headphone outputs, each with its own level knob. This makes it practical for studio tracking sessions, rehearsal rooms, and broadcast positions where up to four performers or engineers need independent monitoring of the same mix. The straightforward layout and compact desktop form factor keep it easy to use in fast-moving recording environments.
