Servo-Controlled Bass Amplifier Protection
The servo-bass amplifier has numerous protection circuits built in to
protect both the amplifier and the woofers. If you over-drive the
amplifier, it will self-protect and you will hear clicking or snapping
sounds. This is caused by the amplifier limiting current to the
woofers (much like the over-rev fuel-cut off in car engines).
If that happens, turn down the volume of your system to protect
your hearing and your speakers. The amplifier is designed to be
current-limited to 20amps
– this is more than enough to supply over
1600W transients to each of the 12” woofers. However, the servo-
system in the G2 is not compression or dynamic limited. Hence, it
is possible to play the system too loud, and damage the woofers
(and also possibly blow out your ribbons).
The amplifier, although it is very efficient, also has a thermal cut-off
to protect against over-heating. Should the bass amplifiers turn off
and the back plate is very hot to the touch, turn the system off until
it cools down again. Additional ventilation might be needed at the
back of the speakers should this happen too often.
A Word about Finish
The midrange/tweeter baffle of the G2jr is constructed out of solid
high-gloss cast acrylic. Acrylic was picked for its sonic properties as
well as its beauty. However, acrylic is a soft material that can
scratch easily.
Every G2jr is delivered with a 3-stage acrylic polish system by
Novus, and fine micro-fibre polishing cloths. Do not use other
cleaners or polish on your G2jr. In particular, DO NOT use paper
towels to wipe the surface of your loudspeakers. Paper fibres are
extremely abrasive and can introduce fine scratches on the surface
that will “cloud” the finish. If dusting is necessary, we recommend a
soft feather duster, or a can of compressed air.
