Visual Sound, Inc. Alpha Concept Loudspeaker alpha V-1/90

Dynacord 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 crossover frequency to the subwoofers is 100Hz. The recommended crossover filter transfer function is Butterworth 12dB/octave. The polarity of the subwoofer channel has to be switched to "inverted" at the active crossover unit (e.g. DSP224, 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 DH1A driver. The HI range above 8kHz is reproduced by DYNACORD's HFT2405 slot radiator 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 crossover 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.
