CONNECTION AND OPERATION
Son Of Bertha can be connected to any musical instrument amplifier capable of driving an 8 ohm load.
To connect your amplifier to Son Of Bertha, run a high quality speaker cable (18 gauge or
heavier) from your amplifier’s speaker output to one of the designated speaker inputs (Speakon or 1/4")
on Son Of Bertha’s input panel.
POWER HANDLING
The power output rating for any amplifier connected to Son Of Bertha should not exceed the enclosure’s
350 watt RMS power handling capacity. Please be aware that exceeding Son Of Bertha’s power han-
dling capacity can void the SWR warranty if any damage occurs to your loudspeakers due to overpower-
ing.
FULL RANGE INPUT AND OUTPUT JACKS
Son Of Bertha features four, full range input/output jacks (two standard 1/4" and two Speakon) wired in
parallel. If you are running two speaker enclosures in parallel, connect the speaker cable from your
amplifier to either jack labeled “IN,” and a second speaker cable from either jack labeled “OUT” to the
input of the second speaker enclosure.
TWEETER ATTENUATOR CONTROL
The large dial found on the input panel of the cabinet is the Tweeter Attenuator. This control is used to
adjust the level of high frequency signal present at the tweeter. A normal setting for this control is
straight up or “twelve o’clock.” Turning the dial fully counter-clockwise removes the tweeter from the cir-
cuit. As you turn the dial clockwise from this position, the high frequency content is increased.
INTERNAL CROSSOVER
Son Of Bertha’s internal (passive) crossover divides the incoming signal into two frequency bands. The
crossover point is 5 kHz (frequencies above 5 kHz are sent to the tweeter, frequencies below
5 kHz are sent to the 15" speakers).
