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.
3. This is done 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 is
muted.
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 then if the low frequencies were going to
the high frequency device!)
After it is confirmed that all transducers are receiving the proper signals, initial calibration can begin.
