A32 Functional Description
The Primare A32 power amplifier is a fully balanced design, this means that the negative
speaker terminals are active, not ground as on an unbalanced design. When performing
measurements, test equipment (such as Audio Precision) that can handle balanced
amplifiers must be used.
The input impedance is 15K and the gain is 26dB. It is possible to obtain just above 250
undistorted watts at an 8R load (both channels driven). The frequency response are flat,
the A32 will drop down only -2dB at 100Khz.
The A32 is equipped with two standby modes, where standby mode 2 is the power save
mode. In power save mode only the standby circuit will be powered by the small standby
transformer placed on the digital PCB.
