Specifications
Packaging Info
Box Dimensions (LxWxH) | 13.3 x 5.5 x 3.4" |
Package Weight | 0.95 lb |
General Information
Frequency Selection | Steps: Selectable 25 or 100 kHz |
RF Power Output | 50 mW |
Pilot Tone | 25 to 32 kHz, 5 kHz deviation (Digital Hybrid mode) |
Frequency Stability | ± 0.002% |
Deviation | ± 75 kHz max. (Digital Hybrid mode) |
Spurious Radiation | 60 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 | 2 kOhms |
Input Limiter | DSP controlled, dual envelope "soft" limiter with greater than 30 dB range |
Gain Control Range | 44 dB, digital control |
Channel | A1 |
Modulation Indicators | Dual bicolor LEDs indicate modulation of -20, -10, 0 and +10 dB referenced to full modulation LCD bar graph |

Audio Performance
THD | 0.2% (typical) |
SNR at Receiver Output | SmartNR: Off 103.5 (no limiting) 108.0 (with limiting) Normal: 107.0 (no limiting) 111.5 (with limiting) Full: 108.5 (no limiting) 113.0 (with limiting) Note: The dual envelope "soft" limiter provides 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 |
Switch Controls | Top panel slide switch; programmable as power, mute, talkback or no (off) function Side panel membrane switches with LCD interface for power on/off and all setup and configuration controls |
Audio Input Jack | 1x Switchcraft 5-pin locking (TA5F) |
