The SA-MEGA11 megaphone delivers reliable voice amplification for coaches, safety personnel, event organizers, and anyone who needs to communicate clearly to crowds. This compact bullhorn projects your voice over 400 yards outdoors, making it effective for sporting events, emergency situations, and crowd management.

The 10-watt amplifier drives a focused horn design that cuts through ambient noise while maintaining speech clarity. The built-in microphone captures your voice naturally, while the foldable pistol grip provides comfortable handling during extended use. Record and playback functions let you store frequently used announcements, saving your voice during long events.

Beyond basic amplification, the SA-MEGA11 includes a siren function for emergency alerts or getting immediate attention. The ABS plastic construction keeps weight down while providing durability for outdoor use. Volume control lets you match output to your environment, from quiet indoor announcements to full-power outdoor projection. The 9-inch overall length and 5.5-inch bell diameter balance portability with acoustic performance.

This megaphone handles crowds up to several hundred people outdoors or fills large indoor spaces like gymnasiums and auditoriums. It's particularly effective for sports referees, school administrators, safety drills, and public events where clear communication is essential.

The unit runs on four C batteries (sold separately) and includes a carrying strap for hands-free transport. Seismic Audio backs the SA-MEGA11 with reliable support and ships direct from our warehouse.

Frequently Asked Questions

How loud is the SA-MEGA11 and what size crowd can it reach?

The SA-MEGA11 delivers 10 watts of power with a range exceeding 400 yards outdoors. This makes it effective for crowds of several hundred people in open spaces or for filling large indoor venues like gymnasiums, auditoriums, or warehouses. The focused horn design ensures your voice cuts through background noise while maintaining clarity.

What batteries does the megaphone require and how long do they last?

The SA-MEGA11 operates on four C batteries, which are not included with the unit. Battery life depends on usage patterns, but typical alkaline C batteries provide several hours of intermittent use. For extended events, consider rechargeable batteries or keep spare alkalines on hand.

Can I record messages ahead of time for repeated announcements?

Yes, the built-in record and playback function lets you store announcements that you use frequently. This feature is particularly useful for coaches with standard instructions, safety personnel with emergency procedures, or event organizers with recurring announcements. Simply record your message and play it back as needed to save your voice.

Is this megaphone suitable for indoor use or just outdoor events?

The SA-MEGA11 works effectively both indoors and outdoors. The volume control lets you adjust output appropriately for your environment. Indoor spaces like gymnasiums, cafeterias, or large meeting rooms benefit from the lower volume settings, while outdoor sporting events or emergency situations may require full power.

How does the siren function work and when should I use it?

The dedicated siren button activates a loud attention-getting tone separate from the voice amplification. Use the siren for emergency alerts, to quiet large crowds before making announcements, or in situations where you need immediate attention. The siren is particularly effective in noisy environments where a voice alone might not cut through.
