CONFIDENCE MONITORS INTRODUCTION 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.
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 fast- attack DSP loudspeaker limiter protects the drivers from overload damage.
2 Analogue Stereo Inputs Fig 1-1: RM-CA2 Confidence Monitor Front Panel The RM-CA2 is a 1U rack-mount unit offering quality loudspeaker monitoring and 2 channel metering of two stereo analogue audio sources. Input 1 has stereo balanced Neutrik™ XLRs and Input 2 has both stereo balanced Neutrik™ XLRs and stereo unbalanced RCA phono connectors, these inputs are mixed together in the analogue domain.
Fig 1-2: RM-CAD8 Confidence Monitor Front Panel 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: The source select button illuminates to indicate loss of synchronisation lock to the incoming digital source.
Fig 1-6: RM-CA2 Source Selector Button Fig 1-7: RM-CAD8 Source Selector Button The Source Selector determines which of the two (RM-CA2) or eight (RM-CAD8) stereo audio inputs is routed to the loudspeakers and metering. Pressing the Source selector button steps sequentially through all input sources. Once the last available source is selected, a further press returns the selection to the first source.
A digital audio input is selected and the digital audio signal is: Main Meters Fig 1-8: RM-CA2 & RM-CAD8 Meters & Phase Error LED The main meters are twin 8-LED cluster, multicoloured bargraphs, displaying the currently selected stereo audio source. The upper meter displays the left channel and the lower meter the right channel.
FRONT PANEL INDIC ATORS & CONTROLS Level and Balance Controls Fig 1-9: RM-CA2 Left Level or 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.
LIMIT indicators Limit active LED’s Fig 1-11: RM-CA2 & RM-CAD8 Meters & Phase Error LED The LIMIT indicators are an additional function of the left hand LED (-34 VU) of the meter scales. 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.
REA R PAN E L CON N E C TI O N S & OP E R AT I ON S are as follows: Pin 1: Ground Pin 2: In-phase signal (“hot”) Pin 3: 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.
