voltage gain

[′vōl·tij ‚gān]
(electronics)
The difference between the output signal voltage level in decibels and the input signal voltage level in decibels; this value is equal to 20 times the common logarithm of the ratio of the output voltage to the input voltage.

In prior articles, I have yammered about the need to isolate the differential pair from the second voltage gain stage to ensure low distortion, especially at 20 kHz.
Rockford's patented Trans-nova technology provides voltage and current gain at the output state (power gain), unlike other amplifier designs that use "buffers" following voltage gain stages, killing current gain and requiring more parts that result in more noise and distortion.
The operational amplifier that is driven differentially from the DAC uses a single voltage gain stage, called a folded cascode, to provide wide bandwidth and good settling time.
This circuit automatically adjusts the voltage gain and pass-band frequency response of the input receiver to compensate for signal loss (attenuation) and distortion over the system's internal distribution path.
Finally we note the voltage gain stages are powered from regulated power supplies.
