sonifex rm m1f106 1

The Sonifex RM-M1F106 is a single stereo channel free-standing meter but with 2 stereo inputs and a front panel source selector.

This unit has a pair of multi-coloured 106-segment bargraph meters for greater display accuracy. A front panel mounted push-button selects the input source to be monitored, from either of the 2 auto-switching analogue or digital AES/EBU stereo inputs, or from a mono mix of each channel, with channel 1 shown on the left meter and channel 2 shown on the right meter.
