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 thumping
sounds. This is caused by the amplifier limiting current to the
woofers (much like the over-rev fuel-cut off in sports 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 the 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 your ribbons).

Due to the efficiency of the amplification modules, they deliver
and draw current extremely quickly. Even though in a well-wired
home it is unlikely, you may find that a very loud bass drum thwack
will cause your lights to dim, or the circuit breakers to trip if you do
not supply enough power to your system.

A possible solution will be to install an additional 20amp circuit in
your listening room, and purchase an additional power supply to
separate the power needs of the left and right woofer towers. Also,
the Maximum Dynamic Headroom Reservoir (developed for the
Genesis Reference Amplifier) is available as an optional upgrade.

A Word about Finish

The G2 is entirely covered in high-gloss acrylic. Acrylic was picked
for its sonic properties as well as its beauty. However, acrylic is a
soft material that can scratch easily.

Every G2 system is delivered with a 3-stage acrylic polish system
by Novus. Do not use any other cleaners or polish on your G2
loudspeakers. 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. If dusting is
necessary, we recommend a soft feather duster.
