Product Description

The CP+ connector panel is a pro-grade audio panel used for making speaker lines and other signal links connected to it available on its front panel.

The device is specifically designed for use with the K&F PLM12K44 and PLM20K44 amplifiers. Output ports include 5 SpeakOn ports, 4 analog inputs, and 4 analog link ports. In addition, the system offers 2 AES/EBU inputs (1/2 and 3/4) and 2 AES/EBU link ports (1/2 and 3/4).
DANTE streams are supported through 1 primary and 1 secondary RJ45 port.

The length of the patch cables at the rear panel is 50 cm (19.7″). In addition to 4 analog inputs (ANALOG IN 1 to 4), there are 2 AES/EBU IN ports (1+2 and 3+4) and 2 2-channel input ports (CH1/CH2 and CH3/CH4).

The patchfield is for commercial use as specified in this document only! Any other use not described in this document is not an intended use

AES/EBU Link

The AES/EBU Link ports are passively wired in parallel to the input ports.
We recommend using these for a low number of member units and with short leads only—for example, for a direct interconnection of 2–3 racks stacked.
Remember to enable AES/EBU termination on the last amplifier in the chain while leaving it disabled on all other amplifiers!
For information on this feature, also refer to the Lake Controller user instructions.

Wiring

Notes

Only use high-quality speaker cables, (i.e. from KLING & FREITAG).
Adapters for connections between the Speakon connecting panel of the CP+ and EP-5 / XLR-connectors, as well as for special uses must be professionally constructed.
For routing analog signals from the mixing console to the CP+ and from the CP+ to the input ports of your amplifier, use 2-pole shielded microphone cables. For transmitting AES/EBU digital audio, use 2-pole shielded cables (110-ohm wave impedance).
Please pay attention to the respective pin diagrams in these user’s manual!
Avoid creating ground loops.
Make sure that the +/- polarity of the speakers at the amplifier is correct. When simultaneously using power amplifiers from different manufacturers, be sure to use the correct specific pin configuration. It may be necessary to modify the pin configuration on the power amplifiers or on the connectors leading to them.
Ensure that the connected speaker channels are working in phase (phase checker).
A phase error can also be recognized when the connected channels are used simultaneously. During simultaneous use the bass frequencies become notably quieter or the mid-frequencies such as voices cannot be located.
The cables should have a sufficient wire gauge. A minimum wire gauge can be easily calculated with the following formula:
Wire Gauge [mm2 = Required Cable Length [m] / 2 x Impedance [Ohm]
Please make sure that the total impedance of the loudspeakers is not lower than the minimal load impedance indicated on the power amplifier.

Make sure that all units are switched off and all controls are turned down before connecting your system.

Connection

To wire the CP+ connector panel inside a rack, connect the amplifier to the rear-panel ports. Doing so will make all ports (speakers, analog and AES/EBU inputs, and network ports) available at the front panel of the rack. This allows for connecting mixing consoles, speakers, players, and other devices right at the front panel.

F irst-time Use

Operating the Controller
Switch off all equipment and turn down all level controls of the mixing console and the power amplifiers.
Wire the speaker systems according to the instructions in these user’s manual.
Now switch on the mixing console first and at last, the power amplifiers. Always use the before mentioned switching order. Otherwise switching noises may damage the system.
If there is interference, turn off all appliances in the reverse order and check all cable connections.
Successively turn up the individual power amplifier channels and send a signal with low volume to the system. Check to see if the desired signals are applied to the intended speakers and make sure there is no interference. Make sure everything works properly, i.e. if the signals come from the correct speaker paths (high signals from the tweeters, bass signals from the bass speaker).
Turning down the input level controls may not always prevent distortions in the input section of the power amplifier, especially if this section has a relatively low headroom.
A clipping signal may not be displayed by the clipping indicator then! To prevent signal interruptions caused by protection circuits or damages to the speakers, turn the level controls of the power amplifier to the maximum position, if possible. Only turn up the signal level at the mixing console or on the controller far enough so that the power amplifiers are not overloaded; or reduce the limiter threshold.
When turning off the system, the input controls for the power amplifiers should be turned down first followed by the power switches of the amplifiers. After that, the other appliances can be turned off
