DSC260 Preliminary Owners Manual Revision 0.9
3.0 A Quick Start
To fully understand the operation and programming of the DSC260, the user should read at least sections 4 through 6. But
since we know that most users have already plugged the unit in and started to explore, here is a quick start to get you up
and running if you have a JBL system that is already programmed in the DSC260.
1. Before making any connections between the controller and the amplifiers, make sure that all power to the
amplifiers is disconnected and their level controls are completely down.
2. The DSC260 has been programmed for many popular JBL Speaker System models. Before connecting the
controller to the amplifiers, this program should be changed to a setting that matches your JBL system.
Appendix B lists the various output assignments.
3. Select the appropriate program by powering on the DSC260 then pressing RECALL. Use the Parameter Plus
and Minus buttons located on the left side of the LCD panel to page up and down until the correct setting is
visible. Press RECALL after the cursor is on the setting.
4. Connect the console outputs to the inputs of the DSC260. Left to A and Right to B. In the case of a mono
system, use input A.
5. Connect the outputs of the controller to the amplifier input channels maintaining the Left and Right identification.
Typically the higher the number of the output, the higher the frequency content. i.e. In a 2 channel 3 way
default, outputs 1 & 2 are Low, 3 & 4 are Mid and 5 & 6 are High. As the outputs vary depending upon the
type of system and program loaded into the DSC260, consult Appendix B for correct output information.
6. Turn on the power to the console, controller(s) and finally the amplifiers. (It is best to turn the amplifiers on last
and off first to prevent any thumps or pops from damaging the transducers.)
7. Apply a signal source to the controller. This can be pink noise, a tone or music.
8. Unmute the outputs on the DSC260, one at a time. The RED LEDs below each Output Meter signify the output
9. Advance each amplifier channel slowly and confirm that the signal reaching the transducers is correct. (It is best
to begin with channels driving the low frequency transducers first. In this way, if the high and low are
reversed, high frequency signals will be going to the woofer. It’s better to find this problem than the low
frequencies going to the high frequency device!)
10. After it is confirmed that all transducers are receiving the proper signals, initial calibration can begin.
