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 it’s 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.
Note:
we do not recommend adjusting the Ohm settings via the adjustable lugs located on one of
the resistors within the unit. They are factory set.
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 prefer the Switchcraft
#11 mono input. We also recommend that your speaker
cabinet wire leads are directly soldered to the to the speaker terminals instead of using the
"
slide
on
"
gripping terminals.
(See special note in the Speaker Cabinet section of this manual).
