The
æro 8
A
can be used full-range. Full-range
use is only recommended for applications where
low SPL level and no bass reinforcement is
required. 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-212A
or
LX-212RA
. In this case different
outputs of the mixing console should be used for
the provide
æro
8A
and the SUBs. The use of an
external delay to control and adjust the phase of
the subs is recommended (with a DSP, for
example). The SUBs units are linked with the
THRU option setting. As well, the amplifier of the
æro 8
A
incorporates signal treatment which
provides frequency range extension down to 95Hz.

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.
In applications where the SUBs need to be delayed, the and use separate signal routing
and control at the processor.
