AFILS Hire Service for Professional Sound System Providers

Introduction

We aim to provide our professional sound system colleagues with a comprehensive and flexible service, enabling you to include AFILS in your systems’ hire range, with a minimum of specialized knowledge and expertise. Your suggestions for improving our service would be appreciated.

We offer the following menu from which you may pick-&-mix to best suit your requirements. The options range from basic design-&-supply to a complete A-Z service. Our complete service includes site survey, design, supply, set-up and test, including delivery to and collection from site. In all cases we will require briefing as to the venue size and shape, type of meeting and any other details which may bear on the system design. This is best done in a telephone consultation. However, we strongly recommend that a survey be completed prior to the first time installation of a loop system in any venue.

If you choose hire-only option (B) you will be supplied with all the necessary equipment to complete and test your installation: loop driver, loop & line cables & connectors, AFILS test-set & monitor headphones, full set-up & test instructions, and an A4 size international loop Logo. Our AFILS design engineer will also be on telephone stand-by to provide technical support, if you run into any snags on site.

Microphones are not included, since we assume that the AFILS will be driven from the line output of your own sound system. Where this is not the case, we can also supply microphones provided we have full details of the application.

A. SURVEY & DESIGN: £60.00 per system

The survey is an essential prerequisite for a first-time installation in any venue. 

B. AFILS SYSTEM HIRE ONLY: £75.00 per day, max £225 per week.

All systems are now fitted with on board metal loss correction, to cover areas up to 500 sq metres depending on the shape of the room and degree of metal loss.

C. FULL INSTALLATION, SET-UP AND TEST, PER SYSTEM: £60.00

Please note that the induction loop driver compression, loop current and metal loss correction must be set up and monitored by a technician who is fully conversant with AFILS technology.

E. TRAINING: £100.00 per 2-hour session

Ferrosound offer training for professional sound engineers and technicians. This rate includes training materials and provides hands-on experience for up to four people.

F. TRAVEL: 85p/m including technician's travel time.

G. TRANSIT: by carrier (POA) or customer collects and returns hire equipment.


SPECIAL LOOP DESIGNS

Special designs, for which a survey is essential, may be required for multiple loops in close proximity, larger loop areas and areas where metal losses are servere. Prices will be subject to survey.

TECHNICAL SUPPORT

Hire customers may telephone for technical support if they have any problems with the set up or operation of the systems. In the unlikely event that you will need to call out our engineer, charges may apply for travel expenses and engineer’s time.


INSURANCE, SAFE CARE & SECURITY OF EQUIPMENT

Please note that our customers are responsible for the safe care, operation and security of all hired equipment, cables and accessories during the hire period, including 3rd party risks, both on and off site, and during transit by the customer.

 

Survey Option

The initial survey is very important. However, this is only required prior to the first-time use of the venue for a loop system. The purpose of the survey is to assess the suitability of the venue for the operation of an AFILS. As such, it is an essential prerequisite for a first-time loop installation in any venue.

It is important that the AFILS conforms to BS 7594 (code of practice) in relation to electro-magnetic field strength, frequency response and other aspects, in so far as this is possible with a temporary installation.

To this end, the survey includes the following essential elements:

1 Measure loop area dimensions in order to calculate aspect ratio and theoretical peak loop current.

2 Monitor electromagnetic interference (EMI) within loop area from all possible sources, especially lighting circuits, to assess viability of AFILS

It is not uncommon for EMI to be so bad, often due to mains lighting loops, that a loop system simply cannot be used. In this event, we can supply a suitable wire-less infrared or radio system – but note: each user will require a receiver unit with headphones. (POA).

3 Assess metal loss effects install test loop, and complete basic frequency response tests. Determine metal loss correction, if practicable within the limits of a temporary installation.

It is often necessary to use a higher current loop-driver than would be theoretically specified for a given loop area. This applies to many modern buildings with a high metal content. For example, an area of 100 sq. metres may require a loop driver designed to cover an area of 500 sq. metres (without loses).

4 Evaluate other factors that may modify the design and set up parameters of the AFILS or, in the worst case preclude the use of a loop system altogether. Such factors include unusual loop shape, ambient noise from traffic or air conditioning, and a requirement for multiple loop systems in close proximity.
