Description

Ampetronic
Phase Shifter & Metal Loss Corrector

The SP5 is a signal processor which introduces a phase shift across the audio band between two separate amplifiers. When specified with a suitable loop design, it is used for a variety of system applications.

Features

  • True 90º phase shift across audio band

  • Compatible with all Ampetronic's professional Induction loop driver range

  • Supplied complete with interconnecting leads

  • Integral metal Loss Correction Control

 

Applications Include

  • Ultra-Low Spill™ systems

  • Rooms with structural metal

  • Adjacent location

  • Balcony cover

  • Large area cover:

  • Stadium

  • Theatres

  • Cinemas

  • Cathedrals

  • Sports Halls

 

An Ultra-Low-Spill™ Induction Loop System uses two carefully designed loop arrays, which are overlaid in the same area, and are driven by two loop drivers. This type of design can reduce the spill field from the loop within 1.5m of the loop perimeter. To minimise any unwanted interaction between the two arrays, the SP5 creates a 90º phase difference between the signals into the amplifiers. The SP5 also incorporates Ampetronic’s Metal Loss Correction system. This same phase shift requirement may also exist when driving balconies which overhang a seating area. The phase shift minimises the interaction between the two loops to deliver a uniform field strength on both floor levels. To greatly reduce the effect of loss due to metal in the building construction, two arrays are often used (as for Ultra-low spill™).

In both cases careful design of the complex loop layout is essential. Ampetronic can offer this design service. The SP5 is built into a standard1/6 rack width unit. Rack mounting trays and blanking plates can also be provided. The SP5 is supplied with the required power lead and input and output signal leads.
