Benchmark DAC3 Measurements


Langston

Recommended Posts

I finished the acoustic domain modifications to my Klipschorns and now I'm working on the electrical stuff.

 

I thought the following measurements might be of interest. They compare the very well-behaved analog output of my Q-SYS Core 250i processor to the analog output of a Benchmark DAC3 connected to the processor's AES3 (digital) outputs. In both cases the processor's AES3 inputs were used to isolate the behavior of the analog outputs. Two loads were used, an easy to drive 200kΩ and a very difficult 600Ω. 48kHz sample rate, 24bits.

 

The Benchmark product, as usual, is in keeping with its namesake.
