Introduction
The RM-2S4 and RM-2S10 are 1U rack-mount units oering quality loudspeaker monitoring
and accurate, high-resolution metering of up to four (RM-2S4) or twenty (RM-2S10 both
analogue and digital) stereo audio sources and more with the addition of optional
expansion cards. Sources may be in any mixture of analogue and AES/EBU digital formats,
with sample rates up to 192kHz accepted.
Sources (and additional Banks of Sources, if tted) are selected via a front panel rotary
encoder, with clear LED indication of the current selection. On the RM-2S10, the Source
LEDs also act as signal present indicators. A pair of line-level audio outputs, congurable
as analogue or AES/EBU digital, follow the selected source at either a xed level or one
mirroring the loudspeaker volume.
The level of the chosen source is displayed on a pair of bright, multicoloured 53-segment
bargraph meters, with a choice of seven accurately modelled scales/responses to suit
dierent applications and local preferences. A separate phase meter indicates channel
correlation or phase error conditions. On the rear panel, open-collector alarm outputs
provide hardware indication of sustained underlevel, overlevel, phase errors and digital
source lock.
Six illuminated pushbuttons provide access to a range of audio ‘modiers’ – instant
dimming of the volume, individual muting of each audio channel, stereo-to-mono
conversion, phase inversion and Middle+Side transcoding. On the rear panel, logic-level
inputs allow direct remote access to the DIM and MUTE functions.
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 and the front-panel headphone socket
automatically mutes the internal loudspeakers when a plug is inserted. A Balance control
allows you to alter the stereo imaging of the left and right channels.
