MB-50 PANEL
The MB-50 is similar to the powered Wedge and Cab with 2 exceptions:
Presence Control: Since it has no internal speakers, the Tweeter control
is replaced by an active Presence Control on the MB-50. Presence can
alter the high frequency component of a signal passing through the
amplifier, adding “brightness” or “sparkle” while retaining a pleasant high-
end quality. The presence circuit is completely disengaged with the knob
turned fully counterclockwise.
Dual Speaker Outputs The MB-50 has dual speaker output jacks, each
of which can handle an 8 load. Both jacks produce identical output.
There is no speaker jack function switch on the MB-50.
PASSIVE CAB/WEDGE PANEL
The driver/crossover/tweeter system in the Passive Cab or Wedge has
the same specs as that in its active counterpart. The Tweeter Level is
adjustable (see
a on p. 5). Connect your amplifier’s speaker output to the
Speaker Input Jack. This jack is hard wired in parallel to the Speaker
Thru Jack allowing you to connect a second speaker cab. (WARNING:
Always observe amplifier load limits!)
