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 90˚ 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.
