Passive 2-way loudspeaker
The Q7 is a 75° x 40° passive 2-way loudspeaker housing two 10" LF drivers and a 1.3" HF compression driver with a rotatable constant directivity horn and a passive crossover network. The two 10" neodymium LF drivers are positioned in a dipolar arrangement providing exceptional vertical dispersion control with the nominal angle being maintained down to 400 Hz. The Q7 with the horn rotated is used to mount the loudspeaker horizontally where space is limited, or the maximum horizontal pattern control is needed and when added to the bottom of Q1 arrays. The Q7 can be used as a stand-alone full range system, in combination with other Q-Series cabinets ground stacked or mounted on a high stand with a swivel bracket. They can also be combined in flown array systems. The Q7 cabinet is constructed from marine plywood and has an impact resistant paint finish. The front of the loudspeaker cabinet is protected by a rigid metal grill, covered with a replaceable acoustically transparent foam. The cabinet incorporates a pair of handles and mounted on the rear panel are two EP5 or NL4 connectors wired in parallel.
- Components 2 x 10"/1.3"
- Dispersion 75° x 40° CD
- max SPL 138 dB
The Q-SUB is an actively driven low compression bass-reflex loudspeaker fitted with a high excursion 18" driver. d&b SenseDrive technology is available when powered by the D12 amplifier. The Q-SUB is mechanically compatible with the Q1 and Q7 ten sockets in the front grill and side panels for Q-Series rigging components permit use in various combinations, either flown or ground stacked.
The Q-SUB cabinet is constructed from marine plywood with an impact resistant paint finish, a pair of handles, four heavy duty wheels and an M20 threaded flange in the top panel to accept a loudspeaker stand. The front of the loudspeaker cabinet is protected by a rigid metal grill covered with replaceable acoustically transparent foam and two EP5 or NL4 connectors wired in parallel are mounted on the rear panel. Two runners protect the bottom of the cabinet from scratching; these are located in correspondingly shaped recesses in the top panel to prevent movement when stacked.
The d&b D12 amplifier is a dual channel amplifier incorporating digital signal processors (DSP) to provide loudspeaker specific configurations and functions.
It is designed for use with all d&b loudspeakers, has both digital and analog signal inputs as well as link outputs, Remote Control and monitoring capabilities and sophisticated protection circuits. It utilizes an autosensing switch mode Power Supply for mains voltages 115 / 230 V, 50 60 Hz (optional 100 / 200 V) and has a temperature and signal controlled fan to cool the internal assemblies.
It is specifically designed to produce high power into low impedance loads, typically those between 4 and 16 ohms. A user definable 4-band parametric equalizer, and signal delay capability of up to 340 ms are incorporated and can be applied independently to each channel. A signal generator offering pink noise or sine wave program is also included.
The D12 uses its Load monitoring and System check functions to ascertain the status of the loudspeaker impedance. d&b System check verifies that the system performs within a predefined condition, whilst d&b Load monitoring enables an automatic and continuous impedance monitoring. Both can determine the status of an LF or HF driver in systems with multiple Elements, even if these are crossed over passively.
Apart from selectable output configurations for dual channel, mixed TOP/SUB and 2-Way Active mode, the D12 also provides d&b SenseDrive for use with the LF drivers in d&b active loudspeakers and Subwoofers and has output connector options. All these functions and parameters can be easily accessed and controlled via the LCD in conjunction with the digital rotary encoder or through the d&b Remote network.
