Used Brand New Alpha V-1/90 Sound Package

alpha V-1/90

The alpha V-1/90 is concepted as a 3-way cabinet in a Coaxial-In-Line topology and serves as a MID-HI component in the large sound reinforcement system alpha.

In conjunction with Alpha B3 or alpha B6 the recommended x-over frequency to the Subwoofers is 100Hz. The recommended x-over filter transfer function is Butterworth 12dB/octave. The polarity of the Subwoofer channel has to be switched to â??invertedâ?? at the active x-over unit (e.g. DSP 260, DSP244). An Electro-Voice EVM15L Pro-Line woofer works into a LO-MID short-horn. The HI-MID frequency range is radiated by an Electro-Voice HP64S rotatable horn system driven by a DH 7 driver. The HI range above 8kHz is reproduced by DYNACORD's HFR 2508 ring radiators with an extremely wide polar pattern. This assures a very comfortable near-field sound quality. Excellent far-throw capabilities are realized due to the Coaxial-In-Line topology of the cabinet.

The alpha V-1/90 is equipped with a passive x-over for the HI transducer and can be Operated in active 2-way mode (LO-MID, HI-MID+HI) or active 3-way mode (LO-MID, HI-MID, HI). The Operating mode can easily be selected by slide switches at the rear panel. Every transducer is reliably protected against critical power levels and short-tem thermal overload by thermo switches and professional halogen radiators in all Operational modes.

The alpha V-1/90 connector panel is equipped with an 8-pole Speakon connector which helps to prevent erroneous connections. The alpha V-1/90 cabinet is made of high-density Mediapan. All corner joints and braces are grooved and glued. The cabinet surface is varnished in structural black. A heavy, powder-coated steel grille protects the front of the cabinet.

Used Cabinet Speakers

Speaker cabinets are specially engineered units in which audio equipment such as speakers and their associated hardware are mounted into. These cabinets can be very basic affairs, little more than a wooden case with no additional features other than one port for inputting a sound cable, or they can be incredibly complex cabinets with features ranging from numerous ports and internal baffles to acoustic insulation and composite materials used in their construction. The main point of housing loud speakers and PA speakers in cabinets is not simply to make them look neat and tidy, although that is one benefit. The cabinet actually provides a useful function in preventing competing sound waves from interacting with each other and distorting the end product. This is because the diaphragm that the speaker driver uses to create the sound we hear generates sound waves both at the front and the rear, and these will be out of sync with each other, thus creating a distortion if not dealt with adequately. Other side effects include echo and reverberation, as the sound waves would reach the audience at slightly different times as they travel on different paths through the loud speakers towards them. In addition to minimizing these unwanted side effects, loud speakerâ??s cabinets also help to manage the vibrations which are caused by the driver frame, as well as the buildup of heat that is associated with amplifiers, driver voice coils and other moving components in PA speakers.
