The Amplified Learning

™

System shall be the Atlas Learn Model AL2430-2PH.

The Amplified Learning System shall be a self contained sound reinforcement apparatus (speakers and wiring not included) for use in K-12 and higher

education facilities or where a room constrained public address system shall be required.

The Amplified Learning System shall be a 3 part construct.

Part 1 of the Amplified Learning System shall consist of an integrated mixer amplifier with a minimum of 30 watt output available as 8Ω, 25V, and

70.7V outputs to local loudspeaker systems. The dimensions of the unit shall not exceed ½ rack width and 1RU tall. The CRS Metal enclosure shall

be powder coated and be capable of rack mounting or mounting by way of a through chassis hole and included mounting bracket 3" x 3" (76.2mm x

76.2mm). The included adaptor bracket shall accommodate a standard projector ceiling mounting pole.

The audio input section of the Amplified Learning System shall have the ability to support 5 separate line level, audio only, input devices labeled

Computer, TV/VCR, CD/DVD, Aux, and Priority Page. Each input shall be comprised of dual summed RCA inputs that feature an independent level

control feeding a common bus. The Aux input shall be dual summed RCA connectors and also include a front panel mounted 3.5mm TRS input that

bypasses the Aux RCA inputs if used. A level control is included on the AUX input in order to set the level relative to the other sources. The ALS shall

include a page priority override that shall be capable of muting all local audio inputs when a page is detected via a connection to the paging system

and by converting the speaker level of 8Ω, 25V, or 70.7V into an input on the integrated mixer amplifier to drive the local speakers connected to the

ALS. The priority page input shall include a level control and a separate input trim control labeled from 1V – 100V for proper matching to the distributed

speaker line. The ALS rear panel shall have 3 coaxial inputs marked “Infrared” for connection to Infrared Sensors (2 are included with the ALS) to

energize two separate input channels (A & B) that provide the ability to deploy a teacher microphone and a second classroom microphone for student

response (if required). Channels A & B each are configured with separate level controls and a common feedback suppression filter set with individu-

ally adjustable frequencies of 100Hz (LF), 3kHz(MF), and 10kHz (HF). The rear panel shall provide a Phoenix type plug in connector which is the access

point to the internal relay output which shall be configured as normally open or normally closed switch contacts suitable for connection to an emer-

gency or panic enunciator.

The integrated mixer amplifier will also be equipped with a line output to drive an optional slave amplifier. The ALS will be powered by an external

24VDC UL listed power supply.

Part 2 of the Amplified Learning System shall consist of an infrared Microphone / System Control Unit with safety breakaway lanyard and ID mounting

clip. The Microphone / Control Module will have provision for an external microphone to be used with the system. The Microphone / Control Unit shall

be capable of transmitting on one of two dedicated IR channels to allow two Microphone / Control Units to be deployed in the same user space with-

out interference. Channel selection shall be via internally mounted A / B switch concealed in the battery compartment along with a separate lockout

control switch to disable the external control functions on the Microphone/System Control unit. Lockout Mode is indicated by a single red illuminated

LED. The ALS microphone control interface is to be equipped with user selectable functions to include Unit On / Off switch, Microphone Level Up /

Down, and Mute Microphone control. The Control Unit Interface functions shall consist of a separate mode selection switch with a provision to allow

for multiple functions to be accomplished from a single control. A single push on shall engage a single blue LED indicating the default operation mode

where the volume control sets the teacher’s microphone level. A double push of the Mode button shall illuminate two blue LED indicators engaging

the secondary control mode where by all other inputs (other than the teacher’s microphone) can be adjusted as a group to control overall system vol-

ume. In the event of a situation requiring outside assistance, a simultaneous engagement of the Mode and Panic buttons will send a signal to engage

a relay that alerts a predetermined location to a need for attention.

Part 3 of the Amplified Learning System shall be comprised of a combination docking and automatic charging station that can be orientated vertically

or horizontally and accommodate two infrared Microphone / System Control Units. The docking and recharging station will automatically recharge and

maintain batteries in the microphone / system control units and accommodate up to 4 additional AA rechargeable batteries as spares. The docking and

recharging appliance shall be powered by an external UL listed power supply appropriate for the country of use.
