Summary
Specifications of a two-radio installed Auracast transmitter, including output power by region, latency, sample rates and input processing.
Key findings
- Maximum output power is +20 dBm in North America and +10 dBm in the rest of the world, adjustable from the regional maximum down to -10 dBm.
- Page 2, Audio Processing, states end-to-end latency with the maker's RX1 receiver of 29 to 45 ms, depending on sample rate and mono or stereo; internal line-in to line-out latency is 13 ms. Other receivers "will vary". The datasheet gives no latency measurement procedure.
- Offers 16 and 24 kHz (Auracast Standard) and 48 kHz (Auracast High), with stated internal responses of 50 Hz to 7.5, 11 and 22.5 kHz respectively.
- Has switchable AGC with a 20 dB control range and a switchable 24 dB per octave low-cut filter (75, 110 or 220 Hz by sample rate). The line input clips at +16 dBu and the microphone input at -25 dBu.
- Additional transmitters can take a stream from another TX2N over the network (multicast RTP) at a nominal 5 ms network latency.
Limits
Manufacturer specifications, not independent measurements. Latency through hearing aids, phones or other receivers is not given.
