LAB12 MIGHTY Class A Single Ended Power Amplifier
Main connections
Connect a High Grade Power cable to the IEC input and to your wall socket. Make sure that your
wall socket provides a good ground before connecting the power cable
.
You must supply 230 to
240 Volts AC (50Hz). (Every
MIGHTY
is tuned and calibrated using the
LAB12 Knack Power Cable
)
Connect to your Preamplifier
Connect the preamplifier analog output to the analog line level input of your MIGHTY Power
Amplifier. Make sure about the correct channel connections. We suggest to use a good quality
interconnect cable pair.
Connect your Speakers
Connect your speakers to the additional output of MIGHTY (connect speakers from 2 to 4 ohm at
4ohm
positive bind, speakers for 4 to 16 ohm at
8ohm
bind). Make sure about the phase and
polarity of speakers, always connect ‘’plus’’ (red) bind of Mighty to ‘’plus’’ (red) bind of speaker
and same with black.
Notes:
You can choose the operation of MIGHTY between triode or Ultra Linear pentode mode, to tune
the sound closest to your taste.
This can be done thru two toggle switches on the back of power tubes. Position both switches
towards to transformers for triode mode or towards to tubes for Ultra Linear pentode mode.
You can change the operation even amplifier is turned on with just lowering the volume.
MIGHTY is fully compatible with the best octal tubes (EL34, 6550, KT88). You can use any of these
three types of tubes with no problem.
For the safety of your equipment
! Make sure that all of your equipment is turned off before any connection.
! To avoid damaging your speakers you have to turn on the MIGHTY
some seconds after turning on your preamplifier and turn it off
some seconds before turning off your preamplifier.
! Never turn on MIGHTY without connected speakers on it. It is
possible to damage tubes or even output transformers.
