Plug-On Transmitter
Rio Rancho, NM

Audio Performance (overall system):
Frequency Response: 35 Hz to 20 kHz (+/-1dB);
Low frequency Roll-off: Adjustable for -3dB @30, 50, 70, 100,
120 or 150 Hz)
THD: 0.2% (typ. 100 Hz to 20 kHz -
see table)
Signal to Noise Ratio (dB) at receiver output:
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 figure for SNR
without limiting by 4.5 dB.
Input Dynamic Range: 125 dB (with full Tx limiting)
Controls & Indicators: • Power/Phantom “ON-OFF”
• Phantom voltage selector
• Audio input gain
• LCD w/membrane switches
• LED audio level indicators
Audio Input Jack: Standard 3-pin XLR (female)
Phantom Power: 5V @ 18 mA max., 15V @ 15 mA
max. and 48 V @ 4 mA max.,
