Sonifex RM-CA2 Confidence Monitor, 2 LED Meters and 2 Analogue Stereo Inputs, 20Hz-20kHz Frequency Response, <50 Ohm Output Impedance, 60dB CMRR

The Sonifex RM-CA2 Confidence Monitor, 2 LED Meters and 2 Analogue Stereo Inputs is using the same outstanding speaker system as the Reference Monitor range, the confidence monitors offer a superb sound with a cut-down feature set. The RM-CA2 is a 1U rack-mount unit offering quality loudspeaker monitoring and 2 channel metering of two stereo analogue audio sources. Input 1 has stereo balanced Neutrik XLRs and Input 2 has both stereo balanced Neutrik XLRs and stereo unbalanced RCA phono connectors. Sources are selected via a front panel push-button switch, with clear LED indication of the current source.

A rear panel DIP switch setting allows the unit to monitor either Stereo signals, with the two front panel control knobs acting as stereo volume and balance control, to alter the stereo imaging of the left and right channels or Dual mono signals, with the two front panel control knobs acting as left and right volume controls. There is a front panel headphone socket which responds to the volume controls and the headphone socket automatically mutes the internal loudspeakers when a plug is inserted. A pair of line-level analogue audio outputs follow the selected source at the selected level or optionally at 10dB lower (if using the unbalanced input), set via rear-panel DIP switch. The level of the chosen source is shown on an 8 segment LED bar-graph display with PPM and VU scales indicated. The bar-graph can optionally be lowered by 10dB (if using the unbalanced input), set via rear-panel DIP switch.

The three-way loudspeaker system is fed via a DSP-based active crossover and a trio of highly efficient Class-D amplifiers. Careful attention to driver selection, materials and case design, plus active DSP equalization, has ensured a flat response and outstanding reproduction from such a shallow unit. A protective limiter prevents damage to the loudspeakers under overload conditions. The RM-CA2 operates from global mains voltages (85-264V AC, 47-63Hz) without adjustment.
