| Reception | True diversity |
| RF tools | Real Time Spectrum Analysis and automatic frequency assignment |
RF & reception
| Specification | Details |
|---|---|
| Tuning | 169 to 1525 MHz (1356 MHz switching bandwidth); 25 kHz steps; SpectraBand Technology for maximum rejection of out-of-band signals; Available frequencies depend on country of operation |
| Modulation | Proprietary, 100% digital RF modulation; Standard, Long Range, or T&M, selectable per channel |
| Spurious Rejection | >100 dB typical |
| Cascade output | 50 ohm |
| Cascade output / 3.5 dB Insertion Loss from front BNC through rear BNC | It is recommended to use an external powered antenna to overcome the 3 dB splitting loss in the Astral ARX8 so that the receivers maintain excellent range. |
| Cascade output | Wideband power split, pre-LNA |
| RF Bias output | 12V, 200 mA each BNC; Smart antenna support, Wisycom-compatible |
Audio outputs & synchronisation
| Specification | Details |
|---|---|
| Latency | Standard modulation = 2 ms, analog or digital outputs; Long Range modulation = 3.9 ms, analog or digital outputs; T&M (Test and Measurement) = 7 ms, analog or digital outputs |
| Audio Frequency Response | 10 Hz–20 kHz, +/- 1 dB relative to 1 kHz |
| Dynamic Range | > 130 dB with an Astral transmitter |
| Analog Outputs | D-Sub 25 output conforming to AES59 'Tascam' standard; Balanced connection; 120-ohm output impedance |
| Analog Output Level / Line | +20 dBu for 0 dBFS |
| Analog Output Level / Guitar | +20 dBu for -5 dBFS (note: same as Line output, but level matched for Astral Guitar Box balanced-to-1/4" unbalanced converter) |
| Analog Output Level / -10 | +6 dBu for 0 dBFS |
| Analog Output Level / Mic | -20 dBu for 0 dBFS |
| Tone Generator | 1 kHz tone, adjustable from -20 to 0 dBFS |
| Audio Output Sample Rate | 44.1, 48, or 96 kHz |
| Digital Audio Output | AES3 balanced connection, 110-ohm output impedance |
| Sync | LTC / Wordclock BNC input, software-switchable 75-ohm termination; 8-Series (when docked) |
Power & distribution
| Specification | Details |
|---|---|
| Sources | DC Input on locking TA4 connector, pin-4 = (+), pin-1 = (-); 8-Series (through unit-to-unit connector when docked); AC mains adapter (XL-WPTA4 sold separately) |
| Levels | DC input, 10 to 18V in, 2A minimum at 10 VDC; 10W idle, default configuration; Extra power passed through for USB power, active antenna power, and DC output power |
| Levels / USB-A | 5V, 500 mA output; supports keyboards, thumb drives, Astral transmitters, and USB hubs |
| Levels / DC Outs | max 500 mA between both outputs. |
Dimensions, weight & environment
