Professional loudspeaker systems are capable of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels (from approx. 95 dB SPL) can cause hearing damage if people are exposed to it over a long period. In order to prevent accidents when deploying loudspeakers on the ground or when flown, please take note of the following: When setting up the loudspeakers or loudspeaker stands, make sure they are standing on a firm surface. If you place several systems on top of one another, use straps to secure them against movement. Only use accessories which have been tested and approved by d&b for assembly and deployment. Pay attention to the correct application and maximum load capacity of the accessories as detailed in our specific "Mounting instructions" or in our "Rigging manuals". Ensure that all additional hardware, fixings and fasteners used for deployment are of an appropriate size and load safety factor. Pay attention to the manufacturers' instructions and to the relevant safety guidelines. Regularly check the loudspeaker housings and accessories for visible signs of wear and tear, and replace them when necessary. Regularly check all load bearing mounting devices. Potential risk of material damage Loudspeakers produce a static magnetic field even if they are not connected or are not in use. Therefore make sure when erecting and transporting loudspeakers that they are nowhere near equipment and objects which may be impaired or damaged by an external magnetic field. Generally speaking, a distance of 0.5 m (1.5 ft) from magnetic data carriers (floppy disks, audio and video tapes, bank cards, etc.) is sufficient. 4 - preliminary - d&b CCL-SUB Manual 1.1 en 2 CCL-SUB loudspeaker Cardioid dispersion pattern d&b CCL-SUB Manual 1.1 en 2.1 Intended use NOTICE! Only operate d&b loudspeakers with the specified and correctly configured d&b amplifiers, otherwise there is a risk of damaging the loudspeaker components and the directional characteristics of the system cannot be achieved. Applicable d&b amplifiers: D40|D80|D90 Product description The CCL-SUB is a compact high performance cardioid subwoofer. It houses two long excursion neodymium drivers in an integrated cardioid setup: a 15" driver in a bass-reflex design facing to the front and a 10" driver in a 2-chamber bandpass design radiating to the rear. The arrangement and tuning provide a cardioid dispersion pattern using a single amplifier channel. Its frequency response extends from 39 Hz to 150/100 Hz. The cabinet enclosure is constructed from marine plywood and has an impact and weather protected PCP finish. The front and rear of the cabinet is protected by a rigid metal grill backed by an acoustically transparent and water repellent fabric. Each side panel incorporates a handle and mounted on the rear panel are four heavy duty wheels. Two runners extend from the rear to the front panel of the cabinet protecting the bottom panel against scratching. Two correspondingly shaped recesses are incorporated in the top panel to accept these runners and prevent cabinet movement when stacking. An M20 threaded flange in the top panel accepts a corresponding pole for the deployment of TOP cabinets. CL-Series rigging components and arrays The cabinets are mechanically connected using the rigging strands on both sides of the cabinet front and a central strand at the rear of the cabinet. All necessary rigging components are mounted on the cabinet and fold out or slide out when needed. A detailed description of the rigging components is given in the respective rigging manuals. Cardioid dispersion Cardioid dispersion avoids unwanted energy behind the system and greatly reduces the excitation of the reverberant field at low frequencies providing the greatest accuracy of low frequency reproduction. The subwoofers can be used as stand-alone solutions or in stacked combinations with a minimum distance of 60 cm (2 ft) between adjacent cabinets or between the subwoofers and a side wall. When positioned in front of walls, the minimum distance to rear walls should be 10 cm (0.3 ft) or is already maintained by the wheels mounted at the rear of the cabinet. - preliminary - 5 NLT4 F/M Connector wiring Frequency response correction of the Coupling function for low and low-mid fequency level* *schematic diagram 2.2 Connections The cabinet is fitted with NLT4 F/M connectors. All four pins of both connectors are wired in parallel. The cabinet uses the pin assignments 2+/2. Pins 1+/1 are designated to TOP loudspeakers. Using the male connector as the input, the female connector allows for direct connection to a second cabinet. d&b LoadMatch With the d&b four channel amplifier platform, the LoadMatch function enables the amplifier to electrically compensate for the properties of the loudspeaker cable used without the need for an additional sense wire. For applicable loudspeakers, LoadMatch is therefore independent of the connector type used. 2.3 Operation Amplifier output mode(s): Dual Channel or Mix TOP/SUB Application Setup Cabinets per channel CCL-SUB CCL-SUB 2 CCL-SUB AP 1 2.3.1 Controller settings For acoustic adjustment the 100 Hz mode can be selected. 100 Hz mode With the 100 Hz mode selected, the upper operating frequency of the system is reduced from 150 Hz to 100 Hz. Coupling function The Coupling function compensates for coupling effects between the cabinets by reducing the low and low-mid frequency level. The SL-Series setups provide a two-stage filter (Low/Mid), which allows the independent shaping of the low and low-mid responses. The characteristics of the Coupling function are shown in the diagram opposite. The standard setting (0) maintains the default array response. Coupling values can be set in the range from +5 to 5 (Low) and from 0 to 8 (Mid) in increments of 0.5. Note: Please note that all cabinets within the array should be operated with the same Coupling setting. When processed conventionally (Line/Arc), the larger the array the more attenuation by Coupling will be required to achieve a neutral response. When operated with ArrayProcessing (AP), an array will automatically be provided with the system target response, as shown in the graphic opposite. All coupling effects caused by the array length and shape are considered in the AP data. The Coupling function may still be used for additional corrections, for example of room properties or coupling effects between main hangs and outfills. 6 - preliminary - d&b CCL-SUB Manual 1.1 en CCL-SUB frequency response, Standard and 100 modes 2.4 Technical specifications Sytem data Frequency response (5 dB Standard) 39 Hz - 150 Hz Frequency response (5 dB 100 Hz mode) 39 Hz - 100 Hz Frequency response (10 dB standard, IEC60268) 35 Hz - 180 Hz Frequency response (10 dB 100 Hz mode, IEC60268) 35 Hz - 140 Hz Max. sound pressure (1 m, free field) with D40/D80/D90 132 dB (SPLmax: Broadband signal IEC60268) Loudspeaker data Nominal impedance front/rear 10 ohms Power handling capacity (RMS/peak 10 ms) 500/1200 W Components 1 x 15" driver front/1 x 10" driver rear Connections 1 x NLT4 F/M Pin assignment 2+/2 Optional front splay 0° or 2.5° Weight 44.5 kg (98 lb) CCL-SUB cabinet dimensions in mm [inch] d&b CCL-SUB Manual 1.1 en - preliminary - 7 3 Manufacturer's declarations 3.1 Conformity of loudspeakers This declaration applies to: d&b Z0884 CCL-SUB loudspeaker by d&b audiotechnik GmbH & Co.
