Description: Up For Your Consideration2-Dorrough 280-D AES/EBU Digital Stereo MetersWith 280-D Rack KitProfessional XLR Wired BreakoutPower Supply READY FOR YOUR NEXT INSTALLATION Dorrough 280-D Digital Loudness Meter The Dorrough Loudness Meter gives you a much more accurate picture of the actual energy content of audio program material than conventional metering. By simultaneously displaying two ballistics, the Dorrough Loudness Meter shows you the relationship between average and peak. You need only adjust the program level until either the peak or persistence reference is reached. This will result in the maximum level, regardless of program content. Material with or without compression can easily be matched for the same listening level. Key FeaturesDigital Audio MonitoringDual ChannelMultiple Installation OptionsSide-by-Side MetersHorizontal DesignDorrough 280-D OverviewSpecifications Compatibility Conforms to all formats defined within the AES/EBU Digital Audio specification, including IEC 958, S/PDIF, and EIAJ CP-340 interface standards. These standards include professional 24-bit and consumer 16-bit formats. Sampling frequencies include 32 kHz, 44.1 kHz, and 48 kHz. Signal Interface RS-422 levels over 75-ohm single-ended and 110-ohm balanced inputs. Transformer isolated (as dictated by the EBU specification) with series DC blocking capacitor on input and output. A buffered feed-through is also provided. These signals are not polarized. Scales “D:” 40 dB in one-dB steps “E:” 60 dB in one dB steps from 0 to -30 dB, and 3-dB steps from -33 to -60 dB Accuracy (both scales) Worst case error: +1.4% to -0.8% of full scale. Typical: better than 0.35% of full scale error. Peak Hold Functions Normal (3-Second Peak Hold), Indefinite Peak Hold, or no Peak Hold. Overrange Indication Top/rightmost 3 LEDs change color to red while tracking the program level peaks when the overrange trigger point is reached. The trigger point is jumper selectable between 1-count over (factory default), or 4-counts over the maximum input level. Electrical Connections All signal, power, and peak hold functions are made to the unit through an eight-pin Euroconnector. Electrical connections are made through screw terminals in the connector. Power Requirements 7 VDC at approximately 600 mA. Dimensions Bezel: 1.45” x 5.00”. Mounting Fits standard 1.45” console opening (minimum 5.0” height and 5.5” depth). Bezel supplied. Weight Approximately 1 pound. Options – Rack mount adapter for one to three units (model 280 only). – 40 dB or 60 dB scale overlay.
