Lectrosonics 400 Series - Wireless Lavalier Microphone System (Block 25)


Frequency Selection: 256 frequencies in 100 kHz steps
RF Power Output: 100 mW (nominal)
Pilot Tone: 25 to 32 kHz; 5 kHz deviation
Frequency Stability: ± 0.002%
Deviation: ± 75 kHz (max)
Spurious Radiation: 90 dB below carrier
Equivalent Input Noise: -120 dBV (A-weighted)
Input Level: Nominal 2 mV to 300 mV, before limiting. Greater than 1 V maximum, with limiting
Input Impedance: Dynamic Mic: 300 ohms Electret Lavaliere: Input is virtual ground with servo adjusted constant current bias Line Level: 2.7 kOhms
Input Limiter: Dual envelope "soft" limiter; greater than 30 dB range
Gain Control Range: 43 dB; semi-log rotary control
Modulation Indicators: Dual bicolor LEDs indicate modulation of -20, -10, 0, and +10 dB referenced to full modulation
Frequency Response: 32 Hz to 20 kHz (+/-1 dB)
THD: 0.2% (typical)
SNR: SmartNR OFF: 103.5 (no limiting), 108.0 (w/limiting) SmartNR NORMAL: 107.0 (no limiting), 111.5 (w/limiting) SmartNR FULL: 108.5 (no limiting), 113.0(w/limiting) (Note: The dual envelope "soft" limiter provides good handling of transients using variable attack and release time constants. Gradual onset of limiting in the design begins below full modulation, which reduces the measured figure for SNR without limiting by 4.5 dB)
Dynamic Range: 125 dB (with full Tx limiting) low frequency roll-off (input)
Adjustment: -18 dB/octave; adjustable from 35 to 150 Hz
Controls: Two position "ON-OFF" power switch Audio input gain knob Low frequency roll-off pot on side panel Two 16-position rotary switches adjust frequency
Audio Input Jack: Switchcraft 5-pin locking (TA5F)
Antenna: Detachable, flexible wire supplied 50 ohm port allows connection to test equipment
Battery: Precision compartment auto-adjusts to accept any known 9 volt battery
Battery Life: 5 hours (alkaline); 10 hours (lithium)
Emission: Emission Designator: 180KF3E
Dimensions: 3.17 x 2.48 x 0.84" (80.5 x 63.0 x 21.3 mm)
Weight: 6.98 oz (198 g), (including battery & antenna)
Package Weight: 1.0 lb
Box Dimensions (LxWxH): 9.7 x 7.8 x 3.0"
