Audio outputs
Rear Panel XLR: Adjustable from -50 dBu to +5 dBu
in 1 dB steps. Calibrated into a typical 10 k
Ohm balanced load.
Can drive 600 Ohm load.
Front Panel Controls and Indicators:
LCD control panel
Main window: Pilot tone; antenna phase, receiver battery
level; transmitter battery status; audio level,
RF level
Freq. window: Frequency, TV channel Transmitter switch
setting
Audio output level
adjustment: -50 dBu to +5 dBu
Batt. level tracking: Receiver and transmitter (9 V batt.) in 1/10th
volt steps, accuracy +/- 0.2 V.
Transmitter (AA battery) x.xxV format,
accuracy +/- 0.05 V.
Timer option available when
transmitter battery is set to NiMH.
Scanning mode: Coarse and fine modes for RF spectrum site
scanning
Audio test tone: 1 kHz, -50 dBu to +5 dBu output, less than
1% THD
Transmitter battery type selection:
9 V alkaline, 9V lithium, AA alkaline,
AA lithium, NiMH
Phase invert: Audio output phase normal or inverted
SmartNR
(noise reduction): OFF, NORMAL, FULL modes
(available in 500 Series mode only)
Audio Performance (overall system):
(These specs apply to 500 Series mode only.)
Frequency Response: 32 Hz to 20 kHz (+/- 1dB)
THD: 0.2% (typical)
SNR at receiver output (dB):
SmartNR No Limiting W/ Limiting
OFF 102.0 106.5
NORMAL 105.0 109.5
FULL 106.0 110.5
(Note: the dual envelope “soft” limiter provides exceptionally good handling
of transients using variable attack and release time constants. The gradual
onset of limiting in the design begins below full modulation, which reduces
the measured figure for
SNR without limiting by 4.5 dB)
Input Dynamic Range: 125 dB (with full Tx limiting)
