Lab12 suara 2 x 50W
Class A 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
.
(Every
suara
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 (RCA or XLR cables) of your
suara Power Amplifier. Make sure about the correct channel connections. We suggest you use a
good quality interconnect cable pair.
Connect your Speakers
Connect your speakers to the additional output of suara (connect speakers from 2 to 4 ohm at
4ohm
positive bind, speakers from 6 to 16 ohm at
8ohm
bind). Make sure about the phase and
polarity of speakers,
always connect ‘’plus’’
(red) bind of suara
to ‘’plus’’
(red) bind of speaker and
same with black.
Triode / Ultra Linear
You can choose the operation of suara between triode or Ultra Linear pentode mode, to tune the
sound closest to your taste.
This can be done through 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.
Always do this selection with your amplifier turned off.
Notes:
Suara is fully compatible with the best octal tubes (6550, KT88, KT120). You can use any of these
three types of tubes with no problem.
Please always set correct bias immediately after any tube
change, always use matched pairs of tubes (contact lab12).
