3.2 Onboard Performance Monitoring
Performance Monitoring. These six LEDs display the
performance status of the internal amplifier:
• TEMP. The LED will illuminate when the internal temperature of the amplifier
module has exceeded the recommended operating limit (64˚ C).
• SIG. This LED illuminates when the input signal exceeds -50 dB.
• -3 dB. When this LED illuminates, the input signal has exceeded
-3 dB, and you are in danger of clipping the ADC.
• LIM. The protection limiter has been engaged when this indicator illuminates.
• CLIP. The clip LED illuminates when the input signal has
exceeded 0.5 dBFS, and the ADC is clipping, or when the amplifier
exceeds the maximum upper limit (load dependent).
• NET. This LED has three states:
• Solid Red. Network not available.
• Solid Blue. Network available.
• Flashing Blue. Network packets are being sent or received.
Power User Tip: Never run your input levels higher than the channel
inputs can handle. If you overdrive the A/D converters, it will cause
digital distortion (digital clipping), which sounds terrible.
3.3 Power
AC Line Connection. CDL-series loudspeakers have a universal power supply that
accepts AC power input between 100 and 250 VAC at 50/60 Hz. Each loudspeaker is
supplied with an AC powerCON® power cord appropriate for the country of sale.
WARNING: Do not remove the center grounding prong or use a ground-
lift adapter, as this could result in electric shock.
WARNING: Connect the powerCON connector on the AC powerCON
power cord to the AC In connection on the amplifier
before connecting
the IEC connection to the AC mains power source.
Power Thru. CDL-series loudspeakers provide loop-thru power. Using
powerCON® Loop-thru cables and an AC powerCON Power cord, you can power
up to six CDL-series loudspeakers on a single 15 amp / 120V (8 am / 240V
electrical circuit.
Loop-thru cable connectors are color coded as follows:
•
Blue. AC In.
• Grey . AC Out.
Power Switch. This is the On/Off switch.
Power User Tip:
If connecting multiple loudspeakers to the same
electrical circuit, make sure that adequate line current is available.
Maximum current draw for each CDL-series loudspeaker is 5.45 Amps.
WARNING: The power switch does not cut AC mains power from the
loop-thru cables. If AC mains power is connected to one CDL-series
loudspeaker, electrical power will be present on all connected loop-thru
cables.
