Connections INPUTS- Using the DataPorts

CONNECTIONS: INPUTS- Using the DataPorts

If used, the DataPort must be connected to a QSC DataPort product using a QSC DataPort cable. Do not use computer cables; they look similar but can cause operational problems with your amplifier and/or DataPort accessories.

The CX168 amplifier is equipped with four QSC DataPort connections that may be used for connecting to accessory QSC DataPort devices. Each DataPort services a specific channel pair; the channels are paired as:

Ch. 1 and Ch. 2

Ch. 3 and Ch. 4

Ch. 5 and Ch. 6

Ch. 7 and Ch. 8

Each DataPort and its associated terminal block input pair can be configured independently (there is no requirement to use a DataPort connection for all channels). Only the Ch.1-Ch.2 DataPort can control the power supply standby mode.

CONNECTORS

The DataPort connection will supply the input signals to the amplifier. If using the DataPort connection for audio input signals, do not apply inputs to the terminal block input connectors. If the DataPort connection is used only for monitoring amplifier operating conditions and NOT for providing audio inputs to the amplifier, then the terminal block inputs may be used to supply the audio inputs to the amplifier.

How to Connect to the DataPort:

Direct mounting of DataPort accessories is NOT supported by the CX168 amplifier. Devices that are normally mounted directly to the amplifier must be mounted remotely and connected to the DataPort using a DataPort cable. This is due to the high density of connectors on an eight-channel amplifier; there is not enough space to allow for accessories to be mounted directly to the back of the amplifier.

If the accessory attaches with a QSC DataPort cable, orient the HD-15 male plug correctly with the DataPort socket on the amplifier (it is “D” shaped and will fit only one way). Push the plug onto the socket firmly and ensure it is seated properly. Finger-tighten the 2 retaining screws. Do not over tighten.

Basic DataPort Notes:

1- The amplifier Gain controls will need to be set at their anticipated high-level setting. Use reduced level setting during setup & test.

2- If using the DataPort for audio input signals, control of the audio level will be accomplished with the DataPort accessory device to which the amp is connected.

3- Control of the amplifier’s AC power standby mode will only be possible via the Ch.1-2 DataPort. The amplifier’s POWER switch must be physically set to the “ON” position to use the standby control feature.

4- The order in which the four DataPorts are connected to external devices makes no difference to the amplifier. However, the host controller to which the amplifier is connected will show the channels in the order that cables are connected.
