FrontRow Pro Digital Infrared Sound-Field Systemfor Educational Institutions & sensitive PA applications requiring absolute RF security.The FrontRow Pro Digital two-channel infrared (IR) wireless microphone sound-field PA system offers unparalleled performance when it comes to running multiple interference free applications in classrooms adjacent to one another, or, when security for sensitive applications is of paramount importance. Since infrared light transmission cannot travel through walls, there is no limit to the number of rooms that can be equipped with these systems. With the FrontRow Pro Digital IR system, any combination of two wireless handheld or body-worn pendant IR microphones may be used at the same time allowing for hands free operation and easy accessibility for multiple users to share. With both ceiling and wall mounted loudspeaker designs, installation is simple whether it be a new construction or for retrofit in an existing building. |

FrontRow Pro Digital Infrared Sound-Field System with adaptive intelligence offers a most time-savings, energy-saving, hassle-free sound reinforcement solution in any classroom sized teaching environment. A powerful digital platform optimizes sound quality, power use, and suppresses feedback before it starts. The FrontRow Pro Digital is a dual system which can operate with two wireless microphones at the same time. The standard pendant style microphone included with all pre packed system provides for hand-free operation while the conventional hand-held microphone (optional) is easy to pass around or place on a floor stand. Both styles are equipped with channel selectors allowing for operation on either one of the two standard infrared carrier frequencies, 2.3 or 2.8 MHz. That means two instructors can teach simultaneously using any combination of pendant microphones and/or hand-held microphones. The 940TM Infrared Wireless Pendant Microphone is equipped with an integrated
directional dual-mic system that ensures uniform sound quality regardless of head movements. The 950H Handheld Infrared Microphone helps increase group participation while reinforcing the values of turn-taking and listening. This durable mini-sized mic is less than 6" tall and weighs a mere 2.6 oz. with battery. The microphone is also supplied with a lanyard (place cursor on 950H image, right) conveniently making it hands free for reading aloud, giving reports or even team teaching. Like the 940TM, the microphone is equipped with an AUX-in jack for sending a secondary audio source such as an MP3 player or portable CD/tape player to the receiver.
The FrontRow Pro Digital 940R receiver design makes it simple to operate. The teachers need only turn
on the wireless microphone to start teaching. The Distributed Ceiling Speaker kit
includes four full range coaxial speakers with four UL listed metal tile bridges and steel back enclosures. This option is ideal
for dropped ceiling installations. The speakers mount flush with the ceiling
tiles for neat and inconspicuous installation. The speaker cable kit includes two
48 ft and two 60 ft 18 AWG 2 conductor cables. 
The IR Speaker kit includes two wall speakers with built-in sensors which makes installation simple. Each IR speaker unit combines the two-speaker enclosure with an infrared sensor using a single cable. With three photo diodes per speaker, robust IR coverage is achieved for room sizes up to 2,500 square feet. The IR speaker kit includes two wall speaker units with built-in sensors, a wall mounting bracket and a combo speaker/sensor cable. The combo cable incorporates a 50 ft 18 AWG two conductor speaker cable and a RG58/u coaxial sensor cable. All speaker and sensor cables furnished by Centrum Sound are original manufacturer's CL3P Plenum-rated cables.

The receiver automatically wakes up from it's energy-saving sleep mode and goes to sleep when the microphone is turned off. A separate volume control for each microphone channel plus
two volume controls for auxiliary inputs gives teachers control over the classroom
auditory experience. Audiovisual sound including CD/DVD, VCR, TV or
computer can easily be mixed in via the two sets of standard stereo RCA connectors on the rear panel. A
three position OptiVoice selector optimizes teacher's voice clarity for
various room noise levels. An output port with an adjustment control provides sound to recorders or other FM transmitters for
rebroadcast, including assistive listening systems for the hard of hearing.
It can also be used to feed an external PA system when used only as a wireless microphone system for
sensitive applications. To avoid potential microphone dropouts,
it is recommended to install remote infrared sensors. The rear panel has
inputs for two wall sensors and one ceiling sensor. Furthermore, the rear
panel features four speaker terminals powered by two internal 20 watts
amplifiers. With two different loudspeaker designs to choose from,
installation of the FrontRow Pro Digital system is possible in practically
any type of facility.
A ceiling sensor kit is recommended with the installation of ceiling speakers. However, there can be situations where wall sensors and/or a combination of sensor styles may be more effective. The sensor kits include 50 ft RG58/u coax cables.
