Italian hi-fi maker Audio Analogue announces a second member of the PureAA line-- the AAphono, a phono-stage preamplifier customers can configure for both moving-magnet and moving-coil cartridges.
The AAphono offers a selection of different gain and loading options for MC cartridges, as well as a range of input capacitance and resistance options for MM cartridges. The company says selecting options is done by simply pressing a button, and the unit stores any adjustments, even if it is switched off or disconnected.
The Cam IQ Outdoor features the same facial recognition technology as the regular indoor IQ, only within a weather- and tamper-resistant body. It also promises "Supersight" with a 4K digital sensor, HDR and 1080p video with up to 12x zoom, and automatically zooms in whenever it senses someone approach the premises.
ENEBY speakers come in two sizes, 20 x 20cm or 30 x 30cm. Both come covered in either black or gray polyester fabric on top of white or black plastic, and the smaller version includes a handle. Making the smaller model even more portable is an optional battery pack adding up to 10 hours of cord-free use.
The plans are part of the "Phase B" guidelines first presented at NAB 2018. An evolution of current Phase A technologies, Phase B covers dynamic metadata, next generation audio (NGA) and high frame rate (HFR). As such, one can expect the use of video formats such as Dolby Vision and SL-HDR, as well as Dolby AC-4 and MPEG-H audio.
As a rule, passive HDMI cables are preferred over active. Active cables pose incompatibility issues with other electronics and are directional. The active end of the cable must be connected to the display, and requires power to supply the on-board electronics. This is typically harvested from unused TMDS voltages, and works well so long the source driving the 5V line has adequate output. Should the source voltage be too low it will draw down the vital 5V line.
The UHD51 is interesting since it is the first in the Optoma 4K range to support full 3D, something absent from all 4K TVs in the market. It is also HDR compatible, and features connectivity through x2 HDMIs (one 4K HDCP 2.2 capable) and a USB power port for streaming from an HDMI dongle.
