Using Your Ampzilla 2000 Second Edition Amplifier
Much thought was put into the design of the Ampzilla amplifier with respect not only to sound, but reliability. It is
built to a very high degree of craftsmanship and intended to be stable and trouble-free for years to come, even under
the most demanding loads. However, it is a powerful and fully differential balanced amplifier with completely floating
outputs. As such, special precautions must be observed for proper, safe operation.
Please read, understand and observe the following. SST will not be held responsible nor accept any repairs under
warranty due to consumer negligence, oversight or improper usage.
●
Never attempt using common grounds in the amplifier output connections. Doing so will likely result in a
blown fuse.
●
Never attempt to “bridge” this amplifier as no increase in power will result. The Ampzilla is, by design, a
balanced bridge circuit.
●
Ensure the power switch on the Ampzilla is switched to OFF when either plugging or unplugging the AC
power cord from your main AC inlet, or damage may occur.
●
Do not defeat the third wire safety ground. Cutting off the round ground pin on the AC plug automatically
voids the warranty. Any damage to the Ampzilla due to improper grounding also voids the warranty.
●
Since the Ampzilla has no fan, it is important that you allow for adequate, unrestricted space for ventilation
around all sides of the unit. Overheating may cause thermal overload (indicated by the “THERMAL” indicator
light on the front panel) which will result in the shutdown of the amplifier until the temperature returns to
normal levels.
Turn-on delay and surge relay protection
Be aware that the Ampzilla has a built-in mechanism to protect your speakers from any inrush turn-on current
surges. A long delay (up to 2 minutes) clamp is connected across the drive circuit at turn-on, preventing any surges
across the load. Music may play initially at turn-on, however the power level will be very small.
Changing a fuse
Between the heatsinks on top of the unit you will see four red LEDs next to four grey caps labeled “FUSE”. Underneath
the caps are the fuses for the Ampzilla 2000, one for each rail. A red LED indicator next to each cap will light if that
fuse is blown. Use a screwdriver or coin to remove the cap and then remove and replace the fuse. The fuse should
be 8A, 250V 1¼”. Obviously, a blown fuse is indicative of a larger issue which may need to be addressed.
