CONNECTION AND OPERATION
Big Bertha can be connected to any musical instrument amplifier that is capable
of driving a 4 ohm load. To connect your amplifier to Big 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 Big Bertha's input panel.
POWER HANDLING
The power output rating for any amplifier connected to Big Bertha should not exceed the enclosure's 700 watt RMS power
handling capacity. Please be aware that exceeding Big Bertha's power handling capacity can void the SWR warranty if any
damage occurs to your loudspeakers due to overpowering.
FULL RANGE INPUT AND OUTPUT JACKS
Big 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 circuit. As you turn the dial clockwise from this position, the high frequency
content is increased.
INTERNAL CROSSOVER
Big 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).
