2 Analogue Stereo Inputs
Fig 1-1: RM-CA2 Condence Monitor Front Panel
The RM-CA2 is a 1U rack-mount unit oering 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, these inputs are mixed together in the analogue domain. The balanced
analogue inputs can be wired unbalanced if required.
Sources are selected via a front panel push-button button, 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 5.
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 input 2),
set via rear-panel DIP switch 1.
A single phase error LED indicates phase error conditions.
The three-way loudspeaker system is fed via a DSP-based active crossover and a trio of
highly ecient Class-D ampliers. Careful attention to driver selection, materials and
case design, plus active DSP equalisation, has ensured a at 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.
