Important:
We recommend that if you intend on using your Komet
Airbrake
in conjunction with much
older,
vintage amplifiers
, that you set your vintage amplifier’s impedance selector to 8
for
the first step of attenuation
(or the first click of the rotary switch)
, regardless of an actual 16
Ohm impedance of the speakers or cabinet used. If your amp and speaker load is 8
set the
impedance selector to 4
in the first step of attenuation. This precaution will lower the
current flowing within the output tubes under full power. We also recommend this same
action with EL84/6BQ5 powered amplifiers. Set the impedance selector of your vintage
amplifier according to the speaker impedance being used in any other
step of attenuation past
the first click.
We recommend that you do not use the Komet
Airbrake
with a 100 Watt plus rated
amplifier for
very long,
extended periods at very high volume levels
(or with the volume
controls “dimed out”). This is because the Komet
Airbrake
is a 100 Watt rated device.
Any 100W amplifier can surpass its 100W RMS rating when cranked way up. This could
possibly over-heat the attenuator causing damage to one or more of the load resistors.
Note
:
The Komet Airbrake will increase its ability to handle an amplifier’s wattage as the
attenuation level increases. The maximum load capability for the Komet Airbrake is 200
Watts under full attenuation. You should not have a problem using the Komet Airbrake with
a 100W amplifier, but it is always best to operate your 100W amplifier and attenuator within
reason.
Final note:
The Komet
Airbrake
power attenuator reduces volume by converting the amp’s excessive
power into heat. The device will get very warm, even hot, during use. Please make sure you
place the unit it in a well ventilated area and never have it covered up.
The Komet
Airbrake
was designed for optimum performance with Komet
and
Trainwreck
amplifiers. The Komet
Airbrake
will work equally well with most other
manufacturer’s amplifiers, but Komet
Amplification only guarantees safe operation with
Komet
and Trainwreck
amplifiers.
A Special Note on Speaker Cabinets and Speakers
: we recommend that you use quality
speaker cable with quality brand male plugs. This is to guarantee a tight fit to the speaker
jacks and cabinet. We also recommend that no matter what brand cabinet you are using with
your amplifier, or any amplifier for that matter, that you use or replace the speaker cabinet
input jack with a quality brand jack. We prefer the Switchcraft
#11 mono input. We also
recommend that your cabinet wire leads are soldered to the to the speaker terminals instead
of using the
"
slide on
"
gripping terminals.
