The LOOP THRU output is an output XLR in

parallel with the input connector and is useful for

daisy chaining the input signal to a number of

boxes, connecting them in parallel.

The number of units that can be linked this

way depends on the output impedance of the

equipment driving the enclosure, such as the mixer

or processor. Typically, to avoid signal degradation,

the maximum number that can be daisy chained is

given by the formula (1250/Z), where Z is the

output impedance of the equipment driving the

enclosure. For instance, a 100 ohm output

impedance allows daisy chaining 12 boxes.

Subwoofer level is controlled via the SUB

LEVEL potentiometer. If separate control and

signal routing to the and is

required (such as for applications where the

subwoofer is run off a console's aux bus as an

effect, or it needs to be delayed), drive each

enclosure model separately from a processor,

using a Linkwitz-Riley 24 dB/octave 100 Hz high-

pass filter for the (so that the missing high-

pass from the is replicated), feeding the

with full-range signal.
