FULL enough noise reduction is applied to remove most of the hiss from nearly any signal source of reasonable quality assuming levels are set properly at the transmitter This additional noise reduction comes at the cost of some transparency for low level room noise yet the GjrEcTROSONICS algorithm remains undetectable under most circumstances RF CONTROLLED DIGITAL NOISE FILTER In addition to SmartNR the UCR511 contains an RF sensitive variable freguency filter which reduces high freguency response under extremely weak RF condi tions This filter does nothing until the RF signal strength drops below 3 uV at which point it begins to roll off high freguencies Usable audio remains unaffected but noise ups or hits occurring near the fringe of reception sound much less harsh OUTPUT LEVEL ADJUST One of several setup screens is provided for adjusting the audio output level in 1 dB steps from 50 to 5 dBu using the SEL Up and Down buttons on the front panel TEST TONE To assist in matching the audio levels of equipment connected to the UCR511 a 1 kHz audio test tone adjustable from 50 to 5 dBu in 1 dB increments is available at the XLR connector This tone is available through the TONE display window BATTERIES The UCR511 operates on two 9 V alkaline or lithium batteries Access to the battery compartment is gained by lifting one end and turning the rear panel door Note Do not use an alkaline and a

13. To put this in perspective the noise generated by the recommended 4 k Ohm bias resistor of many electret lavaliere mics is 119 dBV and the noise level of the microphone s electronics is much higher In order to reduce this noise and thus increase the effective dynamic range of the system the UCR511 is equipped with a Smart Noise Reduction algorithm which removes hiss without sacrificing high frequency response The Smart Noise Reduction algorithm works by attenuat ing only those portions of the audio signal that fit a statistical profile for randomness or electronic hiss Because it isn t simply the same sophisticated variable low pass filter as in Lectrosonics s 300 Series designs much greater transparency is thus obtained Desired high frequency signals having some coherence such as speech sibilance and tones are not affected The Smart Noise Reduction algorithm has three modes selectable from a user setup screen OFF NORMAL FULL OFF no noise reduction is performed and complete transparency is preserved All signals presented to the transmitter s analog front end including any faint microphone hiss will be faithfully reproduced at the receiver NORMAL the factory default setting enough noise reduction is applied to remove most of the hiss from the mic preamp and some of the hiss from lavaliere microphones The noise reduction benefit is dramatic in this position yet the degree of transparency maintained is exceptional
