The FCC requires that the following statement be included in this manual:
This device complies with FCC radiation exposure limits as set forth for an uncontrolled environment. This device
should be installed and operated so that its antenna(s) are not co-located or operating in conjunction with any
other antenna or transmitter.

Audio Performance (Digital Hybrid mode)
Frequency Response:
Mic input: 35 Hz to 20 kHz (+/-1dB); low frequency
roll-off is selectable at 35, 50, 70, 100, 120, 180 Hz
Line/Instrument: 35 Hz to 20 kHz (+/-1dB)
THD: 0.2% (typical)
SNR at receiver output:
Note: The dual envelope "soft"
limiter provides exceptionally good
handling of transients using variable
attack and release time constants. Once activated, the limiter compresses 30+ dB
of transmitter input range into 4.5 dB of receiver output range, thus reducing the
measured figure for SNR without limiting by 4.5 dB
SmartNR No Limiting w/Limiting
OFF 103.5 108.0
NORMAL 107.0 111.5
FULL 108.5 113.0
