SRX900 products feature Neutrik powerCON TRUE1 TOP (True Outdoor Protection) connectors for power connectivity. TRUE1 TOP
connectors are locking 16 A (20 A for USA) mains connectors specifically designed for the demanding needs of the entertainment in-
dustry. These ruggedized sealed connectors feature an IP65 rating and provide protection from degradation caused by UV in outdoor
applications certifed to the UL 50E standard. Additionally, powerCON TRUE1 TOP connectors feature breaking capacity (CBC), meaning
the connectors can be connected or disconnected under active load. In the case of SRX900 Series products, the powerCON connectors
also serve as the mains ON/OFF switch and no additional/secondary power switch is necessary.
8.2 POWER CONNECTORS
SRX900 Series products include two powerCON TRUE1 TOP connectors, one for AC input and one for AC output/loop through. The
loop through connector allows multiple products to be powered from a single power source. Rubber sealing covers are used to maintain
proper water ingress protection when a connector is not in use.
TIP: One input and one output powerCON TRUE1 TOP connector are included with all SRX900 products. Additional con-
nectors can be purchased from authorized Neutrik resellers.
8.1 AC VOLTAGE REQUIREMENTS
The SRX900 Series amplifier module includes a universal power supply with Power Factor Correction (PFC), which can be used on any
line voltage from 90 V to 250 V depending on the region, the type of wiring, and the power distribution panels available. When the line
voltage goes above or below the set voltage limits, a protection circuit engages to protect the amplifier from damage. In this case, power
to the loudspeaker is interrupted and the power LED at the back of the speaker flashes green to notify the user of improper incoming
power.
The maximum number of loudspeakers that can be looped from the AC output connector is determined by the voltage of the power
source, the type of the looped loudspeakers (subwoofers vs full-range, etc.), and the circuit breaker rating. In general, the higher the line
voltage, the lower the current consumption and the larger the number of speakers that can be used on a single line is. Using too many
speakers looped together will not damage the speakers, but it will trip the mains breaker and interrupt audio once the breaker rating
has been reached.
TIP: For detailed single cabinet current draw specifications refer to Section 17 - Specifications . Current draw and inrush
values for a variety of input voltages are available.
