The 659.0 MHz version of the Galaxy Audio AS-900K8 Any Spot Series Wireless Personal Monitoring System is an entry-level, single-channel, UHF frequency system that includes the AS-900T Transmitter and the AS-900R Bodypack Receiver. This fixed-frequency system allows transmission of either mono or stereo formats and is a lightweight alternative for performers who are tired of lugging around heavy and bulky floor monitors or tired of leaving a gig with ringing ears.

The receiver features an 80mW headphone amplifier with a standard 3.5mm (1/8") headphone output. It also contains RF and low battery indicators and a built-in limiter. The AS-900T Transmitter features an L/R level display, two XLR/1/4" combo jack for its inputs, stereo / mono switch, and headphone output with volume control. The transmitter also includes a single rack mount kit for mounting 1 unit in 1 rack space.

The AS-900 Wireless System effectively eliminates stage noise, helps protect from hearing damage, and eliminates feedback that allows the user to move freely around the stage or audience and continue to hear the monitor mix. The monitoring system can replace floor wedges and the amplifiers that power them. Simply plug the system into a monitor out jack on the mixing console, create the desired mix, and you are ready to play. The system comes with a set of EB3 ear buds.

Note: Additional receivers and/or transmitters may be purchased separately.
