This Atlas Classroom Sound System is the perfect solution for K-12 and higher education facilities. This complete audio package consists of one Pure Resonance VCA8 Ceiling Speaker Array and one Atlas Sound AA30PHD 50 Watt Mixer Amplifier.

The Vector 2x2 Lay-In Ceiling Speaker employs (3 smaller 6.5”) very fast transient response aluminum-woofer drivers that are very powerful and stable. Working in unison, these drivers produce clean, powerful, dynamic sound. When designing the Vector the goal was to have the single most important feature at the forefront -- good transient response ("dynamic contrast"). A transient is a sound of short duration. Good transient response can only be achieved if the speaker can deliver its output quickly and cleanly without smearing the original sound, and be completely soundless immediately after. Transients contain the essentials of sound reproduction. They provide the sharp pop from a snare drum, the cutting edge of digital sound, the dynamics of the human voice. Larger 2-way cabinet loudspeaker systems offer relatively slow transient response, and the small high-frequency horn tends to beam a narrow, blaring sound at the listener—end result, muddy sound. By replacing larger speakers with four 6 or 8" drivers increases the driver surface area, while creating more punch and a tight, more focused low-end.

The Atlas Sound AA30PHD is a 30 Watt, 3-Input Mixer Amplifier that is specifically designed for use in 70.7V speaker systems. The AA30PHD features a unique automatic system test using the front panel "Push Here Diagnostic" button. This internal circuitry is designed to check the connected speaker lines for wiring and impedance errors. This test can be activated once all speakers are connected and the circuit automatically verifies that the attached speakers' tap settings do not exceed the amplifier's rated power, no speakers are mistakenly tapped at 8Ω, and the speaker wire is free from shorts. This allows for quick troubleshooting on site and after the sale.
