INPUTINPUT

PHONO LEAD

•Connect the SUB analogue output socket from the G68 Digital Surround Controller to the subwoofer’s line-level input using a phono lead.

On the G68D use the RZ output (or RZ and LZ if you have two subwoofers).

The digital surround controller provides a very high-quality crossover for the subwoofer, and for best results you should use this instead of the subwoofer’s crossover. To do this remove any crossover in the subwoofer or set it to its highest setting (eg 200Hz). The subwoofer crossover can be set from the front panel of the G68; see Subwoofer crossover frequency, page 40.
