The BAT VK-P10 was measured as delivered: set up for a typical low-output moving-coil. All measurements were made from the balanced inputs to the balanced outputs.
The BAT's voltage gain measured 55dB (1kHz). S/N (ref. 1V) was 64dB from 22Hz to 22kHz, 61.2dB from 10Hz to 500kHz (both unweighted), and 78.7dB A-weighted. Pin 2 of the balanced configuration was positive. The input impedance was 46.7k ohms in the left channel, 47.2k ohms in the right.
