Radio Integral’s original catalogue lists a portable megaphone with a built-in siren.
Portable public address
Megaphones for events, sports and field operations.
When a message needs to be heard by a group of people on site, a megaphone is a simpler solution than a radio network or a large public-address system. Radio Integral uses it as a practical complement for outdoor organisation, sports, field activities and temporary gatherings.
Actual audibility depends on ambient noise, the space, speaker position and site conditions.
Power can be supplied by batteries or a 12 V vehicle electrical system, depending on the specific kit.
Applications
Clear voice reinforcement where an immediate public call is required.
A megaphone is not a replacement for a professional PA system, but it is practical when speech must be delivered quickly, locally and with full mobility.
Sports and competitions
Coaches, organisers, marathons, cycling, rowing and other activities spread across a larger area.
Events and gatherings
Directing participants, short announcements, entrances, parking and on-site organisation.
Field teams
Temporary work sites where one person needs to communicate information quickly to a larger group.
Rental preparation
Before handover, we confirm the dates, quantity and intended use.
For a sporting event, public gathering or field activity, provide the date, location, expected noise level and approximate number of people who need to hear the announcements. Based on that information, we can confirm whether a megaphone is appropriate or a different communication system is required.
- functional check before handover;
- battery or 12 V power check;
- brief operating instructions including siren use;
- availability and price are confirmed for the requested dates.
