Passive speakers require the use of an external power amplifier in order to make sound. The power amplifier receives audio signal from a source such as a mixer, amplifies this signal and sends the amplified signal to the passive speaker(s) via speaker cables.
Monitors (sometimes referred to as stage, wedge or foldback monitors) are usually placed horizontally on the floor angled up toward the talent or talker so they can hear themselves and/or other program material such as playback music, other musicians, etc. Many models can also be mounted vertically on a tripod speaker stand.
Our Front of House systems are complete Biamp packages; including mains, subwoofers, two amplifiers, processing, and cables. In a Bi-Amp system one amp powers the subwoofers and one powers the mains, the processor splits the signal into high/mid and low frequencies. We make it easy with everything preset, pre-patched and labeled, just connect the speakers and mixer.
