3 Using the CP2000 Using the CP2000 7 Installation The CP2000 can be mounted in a standard rack and requires 2 rack-space units. In addition to the front-panel rack-mounting holes, the CP2000 also features support brackets at the rear, which offer additional support and should be fixed to the rear of the rack. The CP2000 can also be placed horizontally on the floor or a suitable table. The CP2000 uses a variable-speed low-noise fan to regulate the system temperature, which draws air in from the front and expels it from the rear. For correct operation, it's important that the air flow at the front and rear of the CP2000 is not blocked or restricted in any way. If the CP2000 is mounted in a portable rack with removable front and rear covers, be sure to remove the covers before using the CP2000. Connecting Inputs Warning: Turn off all equipment before making any connections. The inputs for each CP2000 channel comprise of one 1/4" phone jack and one XLR-3-31-type connector. Both connectors are electronically balanced, although they can also be used with unbalanced sources. For optimum performance, use only quality screened cables for input connections. Under no circumstances should you connect more than one sound source to the same channel. The inputs are designed to work with line-level sources, such as mixers, CD players, and other professional audio equipment. The 1/4" TRS (Tip-Ring-Sleeve) phone jacks are wired as follows: sleeve-ground, tip-hot (+), and ring-cold (-). TRS phone plugs should be wired as follows. 1/4" TRS phone plug Tip (hot) Ring (cold) To connect an unbalanced source to an INPUT jack, connect the ring (cold) terminal to the sleeve (ground) terminal, as shown.
