The

æro

12A can be used full-range. Full-range

use is only recommended for applications where
low SPL level and no bass reinforcement is
adequate. To use it in this mode simply plug the
mixer into the enclosure's input.

The most common use will be combined with

the

LX-218A or LX-218RA. In this case different

outputs of the mixing console will be used with the

æro

12A and the SUBs. Both sub systems, LX-

218A and LX-218RA include signal treatment in the
amplifiers extending their frequency range up to
85Hz. As well, the amplifier of the

æro

12A

incorporates signal treatment which provides
frequency range extension down to 70Hz. Due to
this overlap between 70-85Hz the use of an
external delay to control and adjust the phase of
the subs is recommended (with a digital processor,
for example).

The LOOP THRU connector 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 Zc>10Zs, where Zc is the
load impedance and Zs is the output impedance
of the equipment driving the enclosure (mixer,
console, etc). For instance, a mixing console with
100 ohm output impedance allows daisy chaining
20 boxes, when the input impedance of the
cabinets is 20K ohm.

As this diagram illustrates, the control and signal routing to the

and

is separed for

applications where the subwoofer needs to be delayed, driving each enclosure model separately from a
processor.
