It offers premium features like full bandwidth RF scan and Automatic RF Gain Control for unparalleled signal stability and channel availability, all packed in the slimmest form factor available. Patent-pending CueMode allows monitoring of different stage mixes and storing of up to 20 separate channels from one bodypack for quick and easy mix reference. Optional advanced rechargeability eliminates the need for disposable batteries and provides extended usage times with reliable battery life, cycle count, and health metering. The P10T is a networkable, full-rack, dual channel wireless transmitter uséd in conjunction with the P10R Bodypack receiver as part of the PSM1000 Wireless Personal Monitor System. It offers a 72 MHz wide tuning bandwidth, networked remote control via Wireless Workbench software, advanced rechargeability options, and PSM 900 backwards compatibility. Connections include balanced 1/4" and XLR, loop out, dual Ethernet ports, and headphone monitor out. Comes with front or back mountable antennas, and power and Ethernet jumper cables.  Features:Touring-Grade Design and PerformanceFull-rack, dual channel wireless transmitter houséd in a touring-grade, all-metal chassisNetworked control via Ethernet connection vastly simplifies setup for high channel counts and enables remote control via Wireless Workbench softwareInternal power supply with IEC in/out ports enables easy power chaining in the rackBackwards compatibility with PSM900 receivers for simplified inventory managementDiversity bodypack dramatically improves signal reception and increases rangePrecision front-end RF filtering reduces RF interference for a cleaner, stronger RF signal, fewer dropouts, and less audible artifactsCueMode allows monitoring of different stage mixes and storing of up to 20 separate channels on one bodypack for quick and easy referenceBackward compatible with PSM 900 transmitters and receivers (in the same frequency range) to facilitate streamlined inventory management for rental and touring Robust RF Performance and Networked ControlUp to 72 MHz Tuning Bandwidth (region dependent) provides flexibility in today's crowded and unpredictable RF environments.Networked frequency coordination simplifies setup for high channel countsFull bandwidth scan from the P10R bodypack receiver finds clean, compatible frequencies and provides a graphic spectrum plot viewable from the bodypack menu screenSend the identified frequencies and spectrum plot to the P10T transmitter over IR syncProgram compatible frequency assignments from one transmitter to every other P10T transmitter on the network over Ethernet connection for vastly simplified and streamlined setupSpectrum display provides a front-panel spectrum plot with selectable zoomFully compatible with Wireless Workbench 6, which provides advanced RF spectrum plotting, comprehensive frequency coordination, and live monitoring and adjustment of transmitter settings: RF mute enable/disableRF output power adjustmentsAux/line levelAudio input levelChannel/device name edit  Specifications:P10R Wireless Bodypack ReceiverTri-band RF Filtering: -3 dB point 30.5 MHz from the center frequency of each bandActive RF Gain Control: 31 dB (adjusts RF sensitivity to provide more RF dynamic range)RF Sensitivity (20 dB SINAD): 2.2 Squelch Threshold (ﾱ3 dB SINAD) 22 dB SINADAdjacent Channel Rejection: >70 dBIntermodulation Attenuation: >70 dBBlocking: >80 dBImage Rejection: >90 dBAudio Output Power (1kHz @ <1% distortion, peak power, @32 O): 100 mW per outputMinimum Load Impedance: 9.5High Boost: Selectable: +2 dB, +4 dB @ 10 kHzVolume Limiter: Selectable: 3-9Limits volume adjustment knob.
