The following charts, made using an Audio Precision Analyser, accompany our review of the Schoeps VSR5 microphone preamplifier.
Hugh Robjohns reviewed the Schoeps VSR5 dual microphone preamp in SOS November 2010 and the following test measurements, which Hugh took using an audio Precision Analyser accompany that article. You can read the full review in the magazine, or at /sos/nov10/articles/schoeps-vsr5.htm.
This plot compares the total harmonic distortion versus frequency for low, medium and high gain settings (both channels tested and overlaid). This plot simply shows the ruler-flat frequency response from 10Hz to well over 30kHz, along with the various high-pass filter option responses. This plot shows the group-delay (essentially the LF phase shift) resulting from switching in the various high-pass filter options. The trace for the 40Hz filter has a curiously different shape to the others between 200 and 20Hz.
