Description: The RM-2S4 is a1U rack-mount unit offering quality loudspeaker monitoring and accurate, high-resolution metering of up to four 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. Audio inputs can be analogue or digital because they are autoswitching using the left Neutrik™ XLR for AES/EBU, or both Neutrik™ XLRs for analogue inputs and they can be used in any combination.Analogue inputs can be balanced or unbalanced in any combination. The digital inputs have switchable AES/EBU termination for (close-range) bridging operation and there is extra global input gain 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 clear LED indication of the current selection.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 different applications and local preferences. Clear scale labels are provided for you to chose the scale displayed and the 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.Six illuminated pushbuttons provide 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 the DIM and MUTE functions.The three-way loudspeaker system is fed via a DSP-based active crossover and a trio of highly efficientClass-D amplifiers. Careful attention to driver selection, materials and case design, plus active DSP equalisation, has ensured a flat 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.A further five-band parametric equaliser can be accessed for room-equalisation purposes via Sonifex SCi Windows-based remote control software. Source selection, status monitoring and unit ID functions, plus firmware updates to add extra functionality, are all accessible remotely via both USB and RS232 connections in conjunction with Sonifex SCi software. The open control protocol also allows operation with terminal programs or customised applications.An optional addition to the RM-2S4 is an HD video input expansion card, allowing multiple AES groups embedded within an HD-SDI or SD-SDI signal to be de-embedded and monitored (RM-HD1). The RM-2S4 operates from global mains voltages (85-264V AC, 47-63Hz) without adjustment.Technical Specification For RM-2S4Inputs Audio Inputs4 x stereo analogue or AES/ EBU digital (autoselecting)Max level (0dB input gain):+18dBu (analogue)/0dBFS (digital)CMRR:>60dB typicalInput Impedance:20kΩ (analogue) 110Ω (digital with termination switchable)AES/EBU Sample Rate:32 to 192kHz, converted internally to 48kHzInput Gain:0, +6, +12 or +18dB digital gain (switchable)Selection:Front panel rotary control with indicator LEDs Line Level OutputsAudio Outputs:1 x stereo analogue or AES/EBU digital (switchable)Gain re Selected Input:Unity or variable, following volume control (switchable)Maximum Output Level:+18dBu (analogue)/0dBFS (digital)Output Impedance:<50Ω (analogue)/110Ω (digital)AES/EBU Sample Rate:48kHzDistortion:<0.02% (1kHz, +8dBu output)Noise:-84dB RMS, unity gain ref +8dBu outputFrequency Response:20Hz-20kHz +0/-0.5dBCrosstalk1kHz input:10kHz input:Analogue I/O, ref 0dBu<-90dB<-85dB Audio ModifiersModifier Selection:Illuminated front panel pushbuttonsDIM:Reduces speaker audio level by 10dBCUT L & CUT R:Mutes left/right speaker audioMONO:Combines left and right audio inputsPHASE INVERT:Inverts phase of right audio inputM+S:Converts stereo input to Middle (sum) and Side (difference) signals User-Variable EqualisationType:ParametricBands:FiveCentre Frequency:200Hz to 18kHzBandwidth:0.25 to 2 octavesBoost/Cut:±12dBProgramming:Via USB/serial control port Amplifier/LoudspeakersConfiguration:Three-way with stereo mid/ high-frequency drivers & mono low-frequency driverPower Output:2 x 5W (HF) + 20W (LF) with protective limiterCrossover:500Hz (3rd order Butterworth)Distortion (HF Outputs):< 0.05% (1kHz, 3W output)Distortion (LF Output):< 0.05% (100Hz, 6W output)Noise:More than 80dB below full outputVolume:Mute to full volume via front panel rotary controlBalance Trim:±6dB via front panel rotary controlPeak Acoustic Level:102dB SPL @ 2ft Level MeteringNumber:2 x 53-segment tri-colour LED bargraphsCharacteristics:Selectable by switch from:1.
