FrontRow ToGo Add-ons, Replacement Parts and Accessories
FrontRow ToGo Portable Line Array System
The FrontRow ToGo is a totally wireless portable PA and soundfield system. Therefore, it is not only perfect for amplification in classrooms but also suitable for general PA applications in areas that are not equipped with a house PA. It can be placed on a tabletop or put on a floor stand. 
Either way, set up is fast, simple, and convenient. The FrontRow ToGo is also supplied with a pair of wall brackets for permanent installation. A quick release design lets you take it off the wall in seconds and place it on the included table stand or an optional collapsible floor stand.
Wireless Microphones. The FrontRow ToGo system features two built-in wireless receivers for operation in the 216 MHz band. Each receiver has eight user selectable channels for a total of 16 different frequencies. That means two instructors can teach using two hands-free wireless body-worn transmitters or two handheld microphones simultaneously. Or, use a combination of one instructor's wireless body-worn transmitters and a hand-held microphone transmitter to pass around between the students. To improve coverage for larger crowds and/or in odd shaped rooms, one or more wireless 925RS speakers can added as long as they are within the 200 ft. transmission range of the wireless microphones.
Rechargeable Batteries. FrontRow ToGo provides up to 6.5 hours of completely wireless operating time. When done, just drop the wireless microphone(s) into the two-unit charger
and connect the power cord to the loudspeaker. It can't get any simpler than that. In the event of longer scheduled presentations, the 925RS speaker can run on AC power while it also recharge the battery. Wireless microphones can operate for more than 12 hours on a six hour charge but can also operate on regular AA size alkaline batteries.
In and Output Controls. The FrontRow ToGo high-quality directional loudspeakers provide full, clear sound. A separate volume control for each channel, an adjustable tone control, plus a volume control for the auxiliary input port gives teachers control over the classroom auditory experience. MP3/CD players, TV or sound from other audiovisual sources can easily be mixed in via the 3.5 mm input connector. An audio jack with a High/Low level switch provides audio output to recorders or other transmitters for rebroadcasting to other loudspeakers or assistive listening devices.
Line Array Design. The column speaker technology applied in the FrontRow ToGo sound system takes advantage of the effects of cancellation
and reinforcement that occur when spacing two loudspeaker cones a precise distance apart (phase angling). Because the FrontRow ToGo speakers are phase angled, sound cancellation occurs at the top and bottom of the speaker enclosure. This reduces the amount of sound reflecting off the floor and ceiling and therefore reduces reverberation. In addition, reinforcement occurs at the center of the FrontRow ToGo speaker. The sound energy that would ordinarily bounce off the ceiling and floor is directed in front of the speaker. This means that the sound from the FrontRow ToGo speakers drops only 4dB for every doubling of distance up to about 23 feet giving twice the audibility of a conventional speaker at the back of the classroom.
