QSC Audio DSP-3 manual Installation- Connections

Section 2: Installation- Connections

DATAPORT Connection- This section applies to those users interfacing with the QSC DataPort products. If using the DataPort for your audio inputs, DO NOT use the terminal block inputs. If the DataPort is used only for control & monitoring of the amplifier (no audio input through the DataPort), then audio input may be via the terminal-block connectors.

The front-panel DataPort connection is used for connecting to

QSC DataPort products. Use a QSC DataPort cable (male-to-

male) similar to VGA computer monitor cables. Do not use com-

puter VGA cables as they are not correctly constructed for

use with the DSP-3.QSC DataPort cables may be obtained through your QSC distributor or by calling QSC’s Technical Services Department. The plugs and jacks are the same physical size as the RS-232 connections; be careful not to get them confused.

The rear-panel DataPort connection from the DSP-3 to QSC amplifiers is made when mounting the DSP-3 to the rear of the amplifier. The DataPort connection from any other accessory to the DSP-3 is made by orienting the connector properly, inserting it fully into the jack and finger-tightening the retaining screws. The audio signals on the rear-panel DataPort are post-DSP (processed).

Front panel DataPort connection is not required for the operation of the DSP-3.

RS-232 PORT Connection- Connection to the RS-232 port is made using a 9-pin serial data cable (male-to-female). Cable length should be 25 feet or less. Orient the DB-9 plug correctly, insert the plug fully into the RS- 232 port and finger-tighten the retaining screws.

DSP-3 setup and programming takes place through the RS-232 port. Any time setup changes are required to the DSP-3, it must be connected to its host computer through the RS-232 port. If “real-time” control of the DSP- 3 is required, the RS-232 port connection must be maintained as well. If “real-time” control is not required, then the DSP-3 can be setup first and then disconnected from the PC.

The RS-232 connection does not have to be maintained for the DSP-3 to operate.

Setup & programming can also be done via Ethernet network communication when using QSC’s QSControl products. Refer to QSControl documentation for detailed information.

DataPort Connection: 15-pin Cable

RS-232 Connection: 9-pin Cable
