A confident final check before the cart.

Rolls RA63B — professional audio distribution amplifier delivering up to 8 mono or 4 stereo outputs from a single stereo input, for headphone monitoring and signal distribution in studio and broadcast environments. The RA63B takes a single balanced or unbalanced stereo input and distributes it simultaneously to multiple outputs — either 8 independent mono outputs or 4 independent stereo pairs — each with its own volume control. This makes it well suited for studio headphone cue monitoring, where several musicians need the same mix feed but with individual volume adjustments. The compact chassis fits a range of desktop and rack-adjacent installation scenarios. Used by recording studios, broadcast facilities, rehearsal rooms, and installed AV setups.
