In this analogue alternative to the system shown opposite, the G91 is augmented with a G Series The Meridian DSP loudspeakers take their feed from the G91’s digital preamp outputs, with the stereo power amplifier, such as the 2 x 100W G56 shown here, or the more powerful G57. The G51’s speaker volume controlled by the G91’s front-panel knob via the communications link, or via the analogue stereo output can be either fixed or variable, and in this case the latter option is used.
