mplifier limiter indicator lights. When lit,
the level of the signal source should be reduced.
Signal presence indicator at the
amplifiers' inputs.
Indicator light for each amplifier channel.
With PowerCon NAC 3 FCA
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.
With (white) PowerCon NAC 3
DFCB connector. This is used as an AC loop thru
so that up to
boxes can be power
from a single AC line.
G) INPUT:
1=GND (ground)
2=(+) Non inverted input
3=(-) Inverted input
H) LOOP THRU:
Balanced signal XLR. Pin assignments
as follows :
Used for paralleling several units,
which will share the same input. Could also be
used to provide signal for an outboard power
amplifier.
Due to their high efficiency, the Stage Monitor
series amplifiers generate very little residual heat
and therefore do not need a fan for cooling. In
normal use, the amplifier panel will be warm to the
touch.
If the unit stops playing (or just the mid-high or
the bass sections), the amplifier's overheating
protection
may be activated to protect the
components from thermal damage. Overheating
may be due to insufficient cooling, or to very
aggressive use in extremely hot conditions. Do not
use the unit in proximity to high power lights. Once
the amplifier cools down, it switches back on
automatically. If the unit should shut down again,
try
reducing the volume a notch to avoid
overheating.
It is recommended that the red LIMIT LED
indicators are not lit continuously; at most it should
blink only occasionally.
If you wish to have a visual indication at the
mix position of whether the LIMIT LEDs are
lighting, during equipment set-up, closely observe
what mixer VUmeter level corresponds to the level
that lights the enclosure's LIMIT LEDs. That level
that should not be exceeded during the event.
A sound system should be switched on
sequentially. Switch on the self-powered unit last in
your sound system. Switch on the sound sources
such as CD players or turntables, then the mixer,
then the processors, and finally the self-powered
unit. If you have several units, it is recommended
that you switch them on sequentially one at a time.
Follow the inverse order when switching off,
turning self-powered units off before any other
element in the sound system.
Mute all signal sources before switching the
unit on or off.
