To use the weather cover:
1. Loosen the nut on the cable gland.
2. Pass the cable all the way through the nut and the rest of the gland.
3. Attach the input connector to the wires (see Input Connector, below).
4. Once the loudspeaker enclosure is installed, plug the input connector into the
loudspeaker's input cup. Secure the connector to the loudspeaker using the two
captive retaining screws, one on each end.
5. Place the cover onto the loudspeaker's input cup and attach it using the four
screws, lock washers, and flat washers provided.
6. Dress the cable so there is no undue strain on it. Tighten the gland nut until the grommet inside the gland has made a tight seal onto
the cable jacket.
The optional input cover only accommodates the Eurobloc Connector, not the speakON NL4.

System Amplification
The PL Series is meant to be used with CX-Q amplifiers (or future generations) with a
preference for 4-channel models that have more DSP resources. Using an 8-channel
amplifier will result in a loss of EQ precision between 300 and 800 Hz. The exact model
will depend on your application, the number of loudspeakers per channel, and the type
of loudspeaker.
The number in parenthesis means that it may work, but will probably not fully exploit the
loudspeaker (i.e., avoid heavy musical content).
Bi-amp mode: all HF can be run on a CXQ 2K4 amplifier.
If you are using amplifiers of a
different type on HF and LF, please remember that those will have different gains that
will have to be compensated.
The LF section requires the same amplifier as the passive
mode.
System Processing
Q-SYS PL Series are designed to be used with a Q-SYS Core processor only and CX-Q amplifiers. Refer to the documentation of Q-SYS
Designer Software for a description of the settings.

NOTE:
The 8-channel amplifiers don't offer the same DSP resources as the 4-channel amplifiers. As a result, EQ precision between
300 and 800 Hz may be lost. The 8-channel amplifiers are not recommended for critical listening and for Bi amp mode.
