5.3 AC Mains Power Connection
This section details the requirements for the AC mains which is the AC
power connection required by each DSA loudspeaker.
5.3.1 AC MAINS SUPPLY
CAUTION: Read all cautionary notes concerning electrical power in
Chapter 1.
Each DSA Series loudspeaker is rated for a particular nominal AC Mains
voltage: 115 V or 230 V. Provide the loudspeaker with 50 Hz or 60
Hz AC Mains circuit capable of:
100 V to 120 V 220 V to 240 V
DSA230 4 A 2 A
DSA250 8 A 4 A
Before applying power, ensure that the AC Mains voltage matches the
voltage rating on the loudspeaker.
DANGER: DO NOT APPLY 230 V MAINS POWER IF THE VOLTAGE
RATING ON THE LOUDSPEAKER IS 115 V. IMMEDIATE AND CATAS-
TROPHIC DAMAGE TO THE LOUDSPEAKER WILL RESULT AND MAY
CAUSE A FIRE HAZARD, SERIOUS PERSONAL INJURY, OR DEATH.
5.3.2 AC MAINS CABLE
The supplied Neutrik PowerCon NAC3FCA plug mates with the Neutrik
PowerCon NAC3MPA AC MAINS jack on the loudspeaker. Because of
both varying installation and electrical code requirements, neither an
AC Mains cable nor AC mains supply connection are supplied.
1. Supply and connect a 3-conductor power cable to the supplied
PowerCon plug, ensuring a proper ground connection.
2. Supply and attach an appropriate connector for the AC Mains
connection at the other end.
Recommended Power Cable
Conductor Gauge: 14 AWG / 2.5 mm (limited by PowerCon design)
Cable O.D.: 5 mm to 15 mm (limited by PowerCon design)
Recommended
length: Maximum 25 ft / 8 m (for <2% voltage drop at
peak input power)
NOTE: If the power cable is longer than 25 ft / 8 m the voltage drop
will increase.
5.3.3 POWER ON / OFF
There is NO power on/off switch on DSA Series loudspeakers. The
loudspeaker will be powered on (energized) when connected to an AC
mains supply. The LED on the “Signal End” will flash rapidly for about
3 seconds when first powered on. This is normal and indicates the
electronics are being initialized.
