Classroom Sound System

Reach students like never before with an installed Classroom Sound System that is built with the teacher in mind. These days students are bombarded with distractions from their cellphones, laptops, iPads and whatever else the latest gadget is; which in turn leads them to quickly tune out their teachers. To help instructors keep their students attention this installed sound system comes packed with a multi-directional SD4 ceiling speaker array which can be placed strategically anywhere in the room for optimal area coverage. In addition, teachers can be equipped with a wireless handheld microphone or a wireless lapel, giving them the freedom to move around the classroom for Q&A sessions and other activities that fully engage their students. Great for fine arts, debate classes, laboratories, and a variety of other classroom types. This system was designed to give instructors every possible edge to reach their students.

Pure Resonance Audio SD4 SuperDispersion Ceiling Speaker Array

The Pure Resonance SD Speaker employs (4 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 SD the goal was to have the single most import feature at the forefront, good transient response ("dynamic contrast"). A transient is a sound of short duration, and 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 we increased the driver surface area while creating more punch and a tight, more focused low-end.

Atlas Sound AA50PHD Mixer Amplifier

The Atlas Sound AA50PHD is a four input channel mixer amplifier designed for distributed business paging and background music (BGM) systems, small to medium speech privacy systems, and in applications where music on hold (MOH) plus paging is required. With one microphone/line input and three stereo line inputs, the AA50PHD will accommodate a variety of input sources including paging microphones, media players, and digital music receivers. The AA50PHD includes a patent pending automatic system test, the Push Here Diagnostic (PHD).

Electro-Voice R300-HD Wireless Handheld Microphone System

The Electro-Voice R300-HD is a robust handheld UHF wireless system, suitable for any application where the convenience of a handheld transmitter is required. The HT-300 metal handheld transmitter is made to withstand the rigors of daily use while remaining comfortable and light-weight in your hand. The PL22 dynamic microphone is the perfect all-around microphone for singing, speaking engagements, and emcees. The cardioid pickup pattern rejects sounds from the surroundings, helps control audio feedback, and still allows an experienced vocalist to work the microphone. The receiver's dual antenna diversity helps avoid signal dropouts, and its durable metal frame and chassis can either be used on a tabletop, or rack-mounted with optional rack mounting hardware.

Electro-Voice R300-L Wireless Lavalier Microphone System

The Electro-Voice R300-L is a robust UHF wireless bodypack system, suitable for any application where the convenience of a wireless lavalier microphone is required. The system's BP-300 rugged metal bodypack transmitter is simple to use, and is powered by two AA batteries. Included with the system, the ULM18 is a high quality directional (cardioid) condenser lavalier microphone suitable for sound reinforcement or recording of voice, and allows users the convenience of a hands-free presentation or performance experience. Exceptionally useful for sound reinforcement applications, the ULM18’s directional cardioid polar pattern reduces sound system feedback potential when used properly. The receiver's dual antenna diversity helps avoid signal dropouts, and its durable metal frame and chassis can either be used on a tabletop, or rack-mounted with optional rack mounting hardware.

Atlas Sound WPD-RISRL Volume Control

The Atlas Sound WPD-RISRL is a decor style wall plate that is designed for use with the AA50PHD, AA100PHD, AA200PHD, or AA400PHD mixer amplifiers to use the remote input selection (RIS) feature. The WPD-RISRL features an audio source slide selector as well as a source volume control. The unit includes an LED indicator to indicate which source is selected and if it is active. The unit fits in a single gang electrical outlet and uses an 8-conductor interface connection that includes a single 4 position removable Phoenix connector and dual 2 position Phoenix style connectors. When connected to the RIS output on an appropriate AAPHD amplifier, the WPD-RISRL allows for remote selection and volume adjustment of inputs 2, 3, and 4 allowing the rack to remain locked and secured.
