2. 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
3. General Safety Instructions
Warning
Never place your devices
• where they are permanently exposed to direct sunlight,
• near heat sources or open fire,
• where the airflow for cooling is blocked,
• where they are exposed to high moisture,
• where they are exposed to strong vibrations or dust.
Transportation
When transporting the device, make sure that it is protected from vibrations.
Intrusion of liquids
It should always be ensured that no liquids get into the device.
Maintenance and Technical Service
The user should not perform any maintenance or repair work on the unit which goes beyond
the work described in these user's manual. This must be carried out by qualified specialist
staff.
The device may only be repaired by qualified specialist staff when, for example:
• objects or liquids have got inside the device,
• the device has been exposed to rain.
• the device doesn't appear to be functioning properly,
• it has fallen down or the housing is damaged.
Noise
RF interference at power cords or line cables may result in unwanted noise.

4.1.1 Speaker port
Each of the four SpeakOn output ports (2) delivers 2-channel signals. This allows for
implementing system cabling with 4-wire speaker cables.
Tip
When using K&F 2-channel speaker systems (NOMOS XLC, SEQUENZA 10, ACCESS T5/T9,
etc.), ensure correct channel assignment as well as appropriate connection to the amplifier
modules.
Output 1: Pin 1+/1- = Channel 1
Pin 2+/2- = Channel 2
Output 2: Pin 1+/1- = Channel 2
Pin 2+/2- = Channel 1
Output 3: Pin 1+/1- = Channel 3
Pin 2+/2- = Channel 4
Output 4: Pin 1+/1- = Channel 4
Pin 2+/2- = Channel 3

5. 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.
6. Wiring
6.1 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.

6.2 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.
