FCC Notice
NOTE: This equipment has been tested and found to
comply with the limits for a Class B digital device, pur-
suant to part 15 of the FCC Rules. These limits are de-
signed to provide reasonable protection against harmful
interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications. However, there is no guarantee that
interference will not occur in a particular installation.
If this equipment does cause harmful interference to
radio or television reception, which can be determined
by turning the equipment off and on, the user is encour-
aged to try to correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment
and receiver.
• Connect the equipment into an outlet on a circuit
different from that to which the receiver is connect-
ed.
• Consult the dealer or an experienced radio/TV tech-
nician for help.
Changes or modifications to this equipment not ex-
pressly approved by Lectrosonics, Inc. could void the
user’s authority to operate it.

SmartNR (noise reduction): OFF, NORMAL, FULL modes
(available in Digital Hybrid mode only)
Audio Performance (overall system):
Frequency Response: 32 Hz to 20 kHz (+/- 1dB)
THD: 0.15% (system) typical in Digital Hybrid mode
System Dynamic Range:
SmartNR No Limiting W/ Limiting
OFF 103.5 108.0
NORMAL 107.0 111.5
FULL 108.5 113.0
(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 gure
for dynamic range with no limiting by 4.5 dB.
