Product Information The W Audio TPT Series has been engineered with a wide audio frequency range, high Signal to noise ratio and outstanding performance equal to that of any professional wireless systems costing much more. This is achieved through strict component selection and high quality circuit design. A delicately designed silence circuit eliminates static noise when the transmitters are either turned off or out of transmission range. An auto mute circuit is incorporated in these systems to effectively eliminate the popping noise when the switch is turned on or off. Features Dual quartz-controlled diversity receiver Noise lock dual-squelch circuitry eliminates signal and random noise interference in standby mode Separate RF signal and audio output level LED's. Latest SMD technology printed circuit board (PCB) ensures durable and stable quality. Supplied with front-mounted antenna conversion kit, to improve antenna reception when installed into a rack cabinet High quality microphone capsule Long transmission range 19 inch rack mount brackets included
