Joly grins a little ruefully into the wires as he works. . "I could do the wiring-- I've seen some of the setups in the rooms, the modern systems are really made to be understood-- but I don't understand sound itself properly at all. Where the speakers and such would need to go to sound best, you know? Sound, I can give you-- distance transmission, even, if Milliways allows it-- but I'm no musician. I fear we'd lose some nuance. Trying the lights again!"

Click , click , and click--the lights switch on-off-on with a firm, quiet sound of the switch, and no buzzing, even when Joly lets them stay on. He nods, satisfied, and starts fixing things into place.
