Description
The C7-TOP is a 2-way horn loaded loudspeaker that exhibits true constant directivity above a frequency of 600 Hz, ensuring equal sound within the coverage area. The bass-reflex design of the low end allows the C7-TOP to be used without a subwoofer, and with its medium to high sound pressure levels and extended directivity it is ideal for balcony or stadium sound reinforcement, delay and background music playback. Where a more powerful PA system is required a C7-TOP can be stacked with two C7-SUBs. The C7-TOP cabinet is constructed from marine plywood, has an impact resistant paint finish, steel handles and MAN CF4 stud plate rigging points. The front of the loudspeaker cabinet is fitted with catches at the top and bottom for securing an optional wooden lid, and mounted on the rear panel are ratchet strap guide plates, two hinge plates and four heavy duty wheels.
The C7-SUB is a bass-reflex subwoofer specifically designed for use with the C7-TOP providing dynamic performance with high impulse program, a tight full sound and high efficiency. Its extra large bass-reflex tunnel guarantees high sound pressure while minimizing power compression and air turbulence noise. The C7-SUB cabinet is constructed from marine plywood and has an impact resistant paint finish, steel handles and an M20 threaded flange on the top to accept a loudspeaker stand. The front of the subwoofer cabinet is fitted with catches at the top and bottom for securing an optional wooden lid, and mounted on the rear panel are ratchet strap guide plates, two hinge plates and four heavy duty wheels.
The 3 RU two channel D12 amplifier delivers medium to high power into low impedance loads between 4 and 16 ohms and is ideally suited for use in both mobile and installation environments. The D12 contains setups for all d&b loudspeakers and a linear mode. The signal delay capability enables user definable settings of up to 340 msec (=100 m/328.1 ft) to be applied independently to each channel. The same applies to the 4-band parametric equalizer, providing optional boost/cut or notch filtering. The D12 incorporates a digital rotary encoder and a LCD display to configure the amplifier. The D12 utilizes an autosensing switch mode power supply for mains voltages 120 V/230 V, 50 – 60 Hz (optional 100/200V). The D12 amplifier incorporates d&b SenseDrive for accurate control of LF drivers in d&b loudspeakers driven in 2-Way Active mode or in actively driven d&b subwoofers. When the D12 is fitted with EP5 connectors and appropriate 5 wire cabling, d&b SenseDrive can be used, resulting in an extremely precise bass performance even at high levels. NL4 and NL8 connector options are also available. RJ 45 connectors enable access to the Remote network via CAN-Bus. 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.
