What is it?A 1U rack-mount unit offering high-quality speaker monitoring plus high-resolution metering of up to twenty analogue and digital stereo audio sources. DetailsThe RM-2S10 offers ten separate analogue inputs (balanced or unbalanced, in any combination) and ten digital inputs including switchable AES/EBU termination for (close-range) bridging operation. An extra global input gain is also available for both analogue and digital low-level sources. Sources (and additional banks of sources, if fitted) are selected via a front-panel rotary encoder with LED indication of the current selection. The source LEDs on the RM-2S10 also act as signal present indicators. A pair of line-level audio outputs, configurable as analogue or AES/EBU digital, follow the selected source at either a fixed level or mirroring the volume of the onboard speaker. The level of the chosen source is displayed on a pair of multi-coloured 53-segment bargraph meters, with a choice of seven scales/responses to suit different applications and local preferences. Clear labels are provided for users to chose the scale displayed and meter brightness can be adjusted from the front panel. 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. The RM-2S10 includes six illuminated pushbuttons offering access to a range of audio ‘modifiers’ – 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 dim and mute functions. The 3-way speaker system is fed from a DSP-based active crossover and three Class-D amplifiers. A protective limiter prevents damage to the speakers under overload conditions and the front-panel headphone socket automatically mutes the internal speakers when a plug is inserted. A further five-band parametric equaliser can be accessed for room EQ purposes via Sonifex SCi Windows-based remote control software.
