Alto Pro Audio Speakers & Monitors 

Alto is a brand that produces equipment for live sound engineers as well as performers. 

Loudspeakers, also called speakers, take an electrical audio signal and turn it into sound. They can be connected to a Public Address (PA) system, DJ or karaoke equipment, signal processor and effects units and more. They project sound out toward the audience.

Monitor speakers project sound toward the audio engineer or performer. In a live sound context, this enables someone to hear their performance free of any distortion or delay that may be caused by the acoustics of their surroundings, helping them to keep to time and in tune. 

Professional Uses of Speakers

  • Amplifiers - typically used for musical instruments, amplifiers increase the volume originally produced by an instrument by increasing the power of the signal originally generated and passing it through a loudspeaker
  • DJ or karaoke speakers - a wide range of frequencies need to be handled by speakers intended for DJ or karaoke use. Subwoofers will be required to produce the bass frequencies
  • PA systems - named after the function to ‘address the public,’ they are also known as sound reinforcement systems. Either way, they can be used for speech, live or pre-recorded sound. They typically comprise microphones, cables and leads, amplifiers, speakers and speaker stands.  

Things to Consider

  • Drivers, or frequencies to cover
  • Size (physical) and portability
  • Power
  • Audience size
  • Wireless or wired
  • Venue acoustics and layout

Driver Types and Frequencies

A driver is the moving part of a speaker that converts the electrical signals into sound waves. It does this by vibrating at the correct frequency, moving the air which creates pressure waves that you can hear. If you watch a driver when in use, you can see it moving. 

  • Tweeter - high range frequencies between 2,000 Hz - 20,000 HZ
  • Mid-Range - 250-2,000 Hz
  • Woofer -  60-250 Hz
  • Subwoofer - 20-200 Hz

Active vs. Passive Speakers

  • Active - the amplifier is built into the speaker cabinet
  • Passive - most common, require a separate amplifier
