The Loudspeaker Management System (LMS) Concept

Turbosound Loudspeaker Management Systems are more than just electronic crossovers. They provide full digital alignment of all components in the Aspect enclosures, to ensure coherent acoustic output. They also incorporates a number of features which contribute to overall system reliability and ease of setting-up.

All system parameters such as crossover frequencies, limiter settings and equalisation can be simply called up from a factory-set menu, making it possible to maintain consistent and repeatable system performance.

Because the power amplifiers are included as part of the Aspect system, the controllers are able to utilise output limiters which are precisely matched to the system requirements, being pre-set to prevent the amplifiers from clipping. Inputs and outputs are fully balanced, providing isolation between the controller and the amplifier inputs. These factors contribute to high reliability in the adverse circumstances often encountered under arduous touring conditions.

LMS-D24, LMS-D26 and LMS-D6 Loudspeaker Management Systems

Use of the LMS-D2X and LMS-D6 loudspeaker management systems ensures accurate time- alignment of the system drive units and also provides a facility for users to select additional delay, either to compensate for physical displacement of ground-stacked bass enclosures relative to flown high packs, or to provide full range delay for correct image localisation or use in distributed systems. It should however be noted that the high-Q, and therefore long throw, properties of the Aspect system generally eliminates the need for distributed delayed systems, even for very large audiences.

Amplifier Racks

Aspect amplifier racks are fully loaded and fully equipped for the most demanding concert touring applications. They are fitted as standard with two T-25 model amplifiers and three T- 45 model amplifiers, Socapex speaker break-outs as well as local connectors, single phase or three phase mains distribution, and multi-way signal input and link connectors. All the component parts are rigidly mounted in a 12U steel space frame with removeable panels, and housed in a road case with heavy duty wheels.

Power Amplifiers

In addition to the Turbosound T-25 and T-45 model amplifiers supplied with turnkey Aspect systems, the following other power amplifier brands provide sufficient performance and mechanical compatibility to perform well with Aspect loudspeaker systems:
