Sory za zaśmiecanie ale już jestem skołowany a dawno nie gościł u mnie
lampiak.
Mam OBC410 i jutro odbieram ad200
AD1: Paczka jest 8ohm a z tylu na wzmaku są wyjścia 2x 4 ohm i 1x 8ohm
podłączam w ta 8ohm tak ?
AD2: zakładając ze będę miał w przyszłości OBC115 podłączam do 4ohm i
OBC410!do drugiego wyjścia 4ohm? Czy do 8ohm i łącze ze sobą dwie paczki ?
Strona 4. To nie było trudne.
Może kolega znalazł ale nic nie zrozumiał, jest jeszcze rozszerzona
instrukcja napisana przez kogoś z talkbassa. Może się przydać komuś w
przyszłości.

There are 3 speaker outs: 2x 4ohm, 1x 8ohm
WHEN YOU HAVE: ONE 2ohm CABINET:
There is no way to connect a 2ohm cabinet to AD200B.
WHEN YOU HAVE: TWO 2ohm CABINETS:
This can be done if your cabinets are wired in serial (remember that most
of
them are
wired in pararell) and you will have probably rewire them to work in
serial.
If you do this, connect 1st cabinet to 2nd cabinet and then to 4ohm output
in
AD200B (no matter which one).
WHEN YOU HAVE: ONE 4ohm CABINET:
Connect the cabinet to the 4ohm output (doesn’t matter which one)
WHEN YOU HAVE: TWO 4ohm CABINETS:
This can be done if your cabinets are wired in serial (remember that most
of
them are
wired in pararell) and you will have probably rewire them to work in
serial.
If you do this, connect 1st cabinet to 2nd cabinet and then to 8ohm output
in
AD200B (no matter which one).
WHEN YOU HAVE: ONE 8ohm CABINET:
Connect cabinet to 8ohm output.
WHEN YOU HAVE: TWO 8ohm CABINETS:
Connect 1st cabinet to 4ohm output,
connect 2nd cabinet to the second 4ohm output
OR
when your cabinets support parallel chaining:
Connect 1st cabinet to 4ohm output, then connect 2nd cabinet to 1st
cabinet.
WHEN YOU HAVE: ONE 16ohm CABINET:
This can be done only by pulling out a pair power tubes (1 and 3 or 2 and 4),
so
the output transformer will send 2x higher impedance to the speaker jacks.
Of
course, if you pull out these tubes, you’ll loose some power (headroom), but
you
will not damage your speaker cabinet.
So if you do this – connect your cabinet to 8ohm output.
WHEN YOU HAVE: TWO 16ohm CABINETS:
This can be done only by pulling out a pair power tubes (1 and 3 or 2 and 4),
so
the output transformer will send 2x higher impedance to the speaker jacks.
Of
course, if you pull out these tubes, you’ll loose some power (headroom), but
you
will not damage your speaker cabinet.
So if you do this – connect 1st cabinet to 4ohm output, connect 2nd cabinet
to
the second 4ohm output
OR
when your cabinets support parallel chaining:
connect 1st cabinet to 8ohm output, then connect 2nd cabinet to 1st
cabinet.
REMEMBER! USE ONLY HIGH QUALITY PROFESSIONAL SPEAKER CABLE!
YOU CAN’T USE MONO JACK/JACK GUITAR CABLE! IF YOU DO THIS YOU CAN BLOW YOUR
AMP
OR CAB!
