Section 1: Introduction- Quick Start

This quick start section is for those users who want to get up and running with the DSP-3 and Signal Manager software as quickly as possible. It is in no way a substitute for reviewing the contents of the entire hardware manual. It is intended for people familiar with the equipment discussed and should be followed up with a review of the manual and the software help file.

This is the same material covered in the Signal Manager software help file, only presented on paper so that you may “get right to it”.

TURN THE EQUIPMENT OFF & INSTALL THE HARDWARE

 

If you are using the DSP-3 with

Then you need to

QSC Powerlight2, CX, DCA 2-channel, 2-RU am- plifiers (or later direct-mount applications)

QSC 4-channel CX & DCA amplifiers (or later models with full-featured DataPort that do not support direct mounting of the DSP-3)

QSC Powerlight 6.0 or Powerlight 9.0

Mount the DSP-3 to the amplifier by plugging it into the amp’s DataPort and securing it with the supplied hardware. External power may be required for older models (see Appendix).

Mount the DSP-3 remotely and connect a QSC DataPort cable between the amplifier’s DataPort and the DSP-3’s “backside” DataPort. External power may be required for older models (see top of page 2).

Mount the DSP-3 remotely and connect a MODIFIED QSC DataPort cable (male-to-female cable with pin #9 removed) between the amplifier’s DataPort and the DSP-3’s “backside” DataPort. Connect the external power supply to the DSP-3’s EXTERNAL POWER jack.

QSC Powerlight, all except 6.0 & 9.0

a non-DataPort amplifier (QSC USA, PLX or non- QSC models

Mount the DSP-3 remotely and connect a QSC DataPort cable (male-to- female) between the amplifier’s DataPort and the DSP-3’s “backside” DataPort. Connect the external power supply to the DSP-3’s EXTERNAL POWER jack.

Mount the DSP-3 remotely. Connect the DSP-3’s CHANNEL 1 OUTPUT and CHANNEL 2 OUTPUT to the appropriate amplifier inputs (see p.18 for pinouts). Connect the external power supply to the DSP-3’s EXTERNAL POWER jack.

CONNECT THE COMPUTER TO THE DSP-3

Use a 9-pin serial data cable to connect the DSP-3’s RS-232connector to the computer’s available COM port (the 9-pin serial port

connector on the back of the PC). COM1 through COM4 are usable with the Signal Manager software. COM1 is the default port in Signal

Manager; use COM1 for your connection if it is available. If not, you will need to select the appropriate COM port in the Signal Manager

program after you install it in step 5.
