Rear-Panel Connections and Controls
Line Input. This is a balanced XLR connection for line-level input. Use the Line input
to connect the loudspeaker to a StudioLive digital mixer or another mixing console,
either directly or through the Line out connector on another CDL12P loudspeaker.
Direct Out. This is the Direct Out for the line input. Use this to connect to another
CDL12P loudspeakers.
Master Vol. This knob determines the master output level (volume) of the
subwoofer power amplifier. It has no effect on the signal level from the direct
output. Push this control to access all the DSP functions in your CDL12P loudspeaker.
Power User Tip:
A subwoofer can significantly change the frequency response of a
full-range system. A 3-way system with a subwoofer will be 6 to 18 dB hotter below 80 to
100 Hz. Set the appropriate level for your subwoofer before adjusting your system EQ.

Onboard Performance Monitoring
Master Performance Monitoring. These 4 LEDs display
the performance status of the internal amplifier:
• SIG. This LED illuminates when the input signal exceeds -50 dB.
• -3 dB. When this LED illuminates, the input signal has exceeded -3 dB.
• 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).
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.

companion PreSonus subwoofer being used (CDL18s, ULT18, or AIR18s).
When using the CDL12P without a subwoofers, select “Off.”
