SAFETY INFORMATION Ordering the Correct Mains Lead When ordering a Reference Monitor from Sonifex, it is helpful if you can specify your required operating voltage and mains lead. After the product code add: UK, for 230V, UK 3 pin to IEC lead EC, for 230V, European Schuko 2 pin to IEC lead US, for 115V, 3 pin to IEC lead Fig C: Mains Lead Table E.g. order RM-2S4 UK for a UK IEC lead to be supplied.
WEEE & ROHS DIRECTIVE WEEE & RoHS Directives - Sonifex Statement WEEE & ROHS D I RE C T I VE The Waste Electrical and Electronic Equipment (WEEE) Directive was agreed on 13 February 2003, along with the related Directive 2002/95/EC on Restrictions of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS).
REFERENCE MONITORS The Reference Monitor Range is a series of rack-mount audio monitors, combining the latest DSP technology with outstanding audio enclosure design to produce monitors of the highest standards with exceptional sound quality, a comprehensive feature set and good looks in the rack. Uniquely an embedded 5 band parametric EQ allows you to configure the monitor for your environment or to suit your listening tastes.
REFERENCE MONITORS Each of the drivers is magnetically shielded so that the monitors are perfectly safe to use near CRTs and TFT displays and each speaker uses a separate, highly efficient class-D switching amplifier. Even cable lengths to and from the speaker enclosures have been kept short to reduce any potential microphonic induction. REFEREN CE MON I TORS DSP Based Design The use of a modern electronic architecture allows a much better audio performance to be realised.

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.

If this indicator is not on, the most likely reason is simply the absence of mains power, but under fault conditions it may also indicate a ruptured mains fuse or a problem with the internal power supply module.

Auto-Selection of Inputs As standard, the RM-2S4 has auto-selection of the inputs, i.e. whichever analogue or digital signal is connected to the input will be used.
REFERENCE MONITORS RM-2S4 & RM-2S10 1 Source Presence Indicators (RM-2S10 only) On the RM-2S10, the presence of active audio on a Source input is indicated by green illumination of the corresponding Source LED. The currently selected Source is indicated by yellow illumination. This feature may optionally be disabled through the use of the remote control OPT command (see the appropriate section of this manual).

REFERENCE MONITORS RM-2S4 & RM-2S10 1 Meter Labelling Each meter characteristic possesses different scaling, range and ballistics according to the relevant British or International standards and self-adhesive scales for each of the characteristics are supplied with the unit. Once the desired meter characteristic has been chosen, proper scale labelling may be ensured by removing the appropriate scale from the backing paper and applying it to the recess provided between the two meters.
1 REFERENCE MONITORS RM-2S4 & RM-2S10 PHASE Meter RE FER ENC E M O NITORS RM - 2S4 & RM - 2 S 1 0 The five-segment LED phase meter indicates the average phase correlation between the left and right channels of the currently selected stereo audio source. It is labelled in both degrees of phase shift and amount of correlation. The phase meter is an “output” meter, reflecting exactly what is being heard from the loudspeakers including any front panel signal modifiers that are active.
REFERENCE MONITORS RM-2S4 & RM-2S10 1 Inserting a plug into the headphone socket automatically mutes the internal loudspeakers. STATUS LED Indicators Fig 1-14: Status LEDs The protection limiter is a fast-attack, slow-release type. Brief flashes of the LIMIT indicator on signal peaks are not cause for concern, but significant illumination indicates that the signal is being compressed and that reproduction may be compromised. In those circumstances the setting of the volume control should be reduced.
1 REFERENCE MONITORS RM-2S4 & RM-2S10 Audio Modifiers R EFER EN C E MO NITORS RM - 2S4 & RM - 2 S 1 0 The audio modifiers are controlled using the 6 white illuminated buttons on the front panel. Each of the modifiers is operated via an illuminated pushbutton switch, with each press of the button toggling the modifier from on to off or vice-versa. When using the audio modifiers in combination, it is necessary to consider the order in which they are applied since that will affect the results.
REFERENCE MONITORS RM-2S4 & RM-2S10 1 PHASE INVERT Audio Modifier When on, the PHASE INVERT button is illuminated and the right channel of the currently selected stereo audio Source is inverted (phase shifted by 180 degrees) prior to further processing and reproduction. The PHASE INVERT modifier will affect the loudspeaker audio, line-level audio outputs, phase meter reading and also, by default, the main meter readings (refer to the Main Meters section of this manual).

REFERENCE MONITORS RM-2S4 & RM-2S10 1 The AES/EBU Lock output is a real-time (non-latching) status output which becomes active if a valid AES/EBU signal is detected on the currently selected Source input. By default, the open-collector output is low (conducting) when a valid AES signal is detected, but this behaviour may be reversed using the serial remote control LCK: command. The active-low control inputs all have internal pull-ups. Equipment driving these inputs need sink only 1mA and block 5V.
