Sonifex S1 Radio Mixer (Pre-Owned)

The Sonifex S1 mixer is a high performance compact, low cost, fixed format mixing console designed for on-air radio use. It can be fitted flush into a desk-top or can be rack-mounted by the addition of optional rack ears.

The rear connectivity panel can be rotated 90ž onto the base of the unit providing easier connection to the unit when it is rack-mounted. It has an integral universal switch mode power supply, which uses an IEC inlet.
