Spatial Audio Raven Preamp

@yyzsantabarbara The remote on the Raven works very well even at 20-25 ft as long as it has a clear line of sight to the preamp

My last question on the Raven Revelation preamp.

Does it support the Balanced standard, AES48?

I keep my amp far away from the gear. I also sold my Holo Serene preamp a few days ago (an excellent SS preamp) and now looking for a tube preamp to fill the void.

@yyzsantabarbara The Raven employs an output transformer so should support AES48. There is a correct loading for the output transformer that will prevent it ringing- you might inquire how that is handled.

Traditionally if the output transformer is designed to drive a low impedance balanced line, it will be designed to drive 600 Ohms. On older gear if the load wasn't present on the line there would often be a switch allowing a 600 Ohm resistor to be placed across the output of the transformer to prevent ringing. A that point a much higher impedance load (10K-100K) could be placed across the output with no worries about being able to drive it.

Perhaps @donsachs will respond with more information.

The Raven will drive any power amp with an input impedance between 10K to 220K, in either RCA single-ended mode (which uses half the transformer secondary) or XLR balanced mode (which uses the full secondary). The output transformer is optimized to deliver clean square waves over this impedance range.

As Lynn said, don't sweat long XLR cables.  The Raven will happily drive them.
