Current consumption
Data obtained at 230V, multiply per 2 for 115V.
Maximum power: Measured in conditions of severe
clipping.
AC power requirements
The required voltage for all models is:
115V, 50Hz/60Hz - 230V, 50Hz/60Hz
Maximum voltage (divide by 2 for 115V):
255V
Shutdown voltage for
variant 25A
(divide by 2 for
115V):
160V

systems.
G) LOOP THRU:
H) ARRAY EQ: In order to compensate for the
summing of the mid and low frequencies, the
onboard signal processing of each
variant 25A
unit
provides high frequency boost. The signal
treatment has been designed to provide optimum
response for arrays of 6 or more cabinets, so
when employing just two or three units it may be
appropriate to lower the high frequency level. The
ARRAY EQ switch can be used to attenuate the
equalization of the very high frequencies in -3 dB
steps.
Used for paralleling several
units, which will share the same input. The output
can also be used to provide signal for an outboard
power amplifier.
The
variant 25A
is a two way class AB self
powered system. Nominal amplifier power
(Continuous) per way: LF:125 W HF:75 W.

connector. Only when the connector is inserted
and rotated (clicked) into place will the AC turn on.
The connector can be used as a switch, rotating
the connector to or from the locked position will
turn the unit on or off, respectively. Mute the signal
feeding the INPUT before turning the unit on or
off.
