SAFETY INFORMATION Safety Information Safety of Mains Operated Equipment This equipment has been designed to meet the safety regulations currently advised in the country of purchase and it conforms to the safety regulations specified by use of the CE Mark. SAFE T Y IN FORMAT I ON Warning : There are no user serviceable parts inside the equipment. If you should ever need to look inside the unit, always disconnect the mains supply before removing the equipment covers.
SAFETY INFORMATION Ordering the Correct Mains Lead When ordering a Confidence 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-2CA2 UK for a UK IEC lead to be supplied.
WEEE & ROHS DIRECTIVE WEEE & RoHS Directives - Sonifex Statement WEEE & ROH S 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).
CONFIDENCE MONITORS INTRODUCTION The Confidence 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. Detail In The Design In the design of the product, every care has been taken to ensure the best and most accurate reproduction of the audio sources.
1 CONFIDENCE MONITORS INTRODUCTION DSP Based Design The use of a modern electronic architecture allows a much better audio performance to be realised. The DSP-based, 3rd-order active crossover provides perfect separation between mid-range and bass sounds. A DSP-based electronic equalisation is used to flatten the frequency response and the fastattack DSP loudspeaker limiter protects the drivers from overload damage.
CONFIDENCE MONITORS INTRODUCTION RM-CA2 1 Confidence Monitor, 2 LED Meters & 2 Analogue Stereo Inputs Fig 1-1: RM-CA2 Confidence Monitor Front Panel Sources are selected via a front panel push-button button, with clear LED indication of the current source.
1 CONFIDENCE MONITORS INTRODUCTION RM-CAD8 Confidence Monitor, 2 LED Meters, 2 Analogue & 6 Digital Stereo Inputs Fig 1-2: RM-CAD8 Confidence Monitor Front Panel CO NFIDE NCE MONITORS INTROD U C T I ON The RM-CAD8 has all the features of the RM-CA2 together with the ability to select from an additional 6 stereo digital inputs. As well as the 2 stereo analogue inputs there are also: • 1 x stereo S/PDIF unbalanced input on RCA phono female. • 1 x stereo TOSlink unbalanced input on an optical connector.
FRONT PANEL INDIC ATORS & CONTROLS 2 Front Panel Indicators & Controls Fig 1-4: RM-CA2 Front Panel Controls Power LED The POWER LED illuminates whilst internal power is present within the unit. 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.
2 F RO N T PA NEL INDIC ATORS & CO N T RO LS Sync Lost indicator On the RM-CAD8 the Sync Lost indicator flashes when one of the following conditions is met. A digital audio input is selected and the digital audio signal is: • missing, • has a sample rate outside the acceptable range of the unit, • contains invalid/non-audio data, • or is too weak for the receiver to lock on to.
FRONT PANEL INDIC ATORS & CONTROLS 2 Level and Balance Controls Fig 1-10: RM-CAD8 Right Level Balance Control and Power On Indicator or Stereo Level Control There are two modes of operation for the level and balance controls determined by DIPSwitch 3. When the DIPSwitch is off, the level for each channel is independently controlled.

When the level potentiometer gain is applied to the incoming signals the resulting signal can exceed the maximum input levels into the D-class amplifier.
REAR PANEL CONNEC TIONS & OP ER ATION S 3 are as follows: Pin 1: Pin 2: Pin 3: Ground In-phase signal (“hot”) Out-of-phase signal (“cold”) Unbalanced signals may also be used by linking pins 1 and 3 and applying the unbalanced signal to pin 2. For the RM-CAD8 there is also an S/PDIF unbalanced digital stereo audio input on a RCA phono connector and a TOSLink optical digital stereo audio input.

This switch will mainly be used when the unbalanced inputs are used.
