Getting Started With I-Tech
Welcome! Operating your Crown
®
I-Tech amplifier can be as simple or advanced as you
wish. Right out of the box, it works like any other amplifier with stereo loudspeaker loads.
You can refer to this Quick-Start Guide to get up and running quickly. For Bridge-Mono oper-
ation, see page 2 of this guide. To learn about I-Tech’s many advanced features, please see the
I-Tech Operation Manual. For example, the manual describes how to control and monitor the
amplifier with Crown’s IQ
®
Network software, and how to load DSP presets or perform diag-
nostics using the amplifier’s LCD control screen (Figure 3).
Stereo Wiring
Let’s assume that you unpacked and installed your amplifier with the proper cooling. If not,
see Section 2 in the I-Tech Operation Manual. We’ll also assume that you will operate the
amplifier in stereo.
If you want to operate your amplifier in Bridge-Mono, skip to page 2 in
this guide.
1.
IMPORTANT: Turn off the amplifier. Unplug its power cord from the AC
outlet. The amplifier must be grounded when plugged into AC power.
2.
See Figure 1. Connect two cables from your mixer output to the amplifier’s XLR input
connectors.
3.
Using Class 1 wiring, connect speaker cables either to the amplifier’s Speakon
®
connec-
tors (as in Figure 2) or to the 5-way binding posts (as in Figure 1.)
4.
Turn down your mixer master faders. Plug the power cord into the amplifier and then into
an AC outlet. Turn on the front-panel power switch. The LCD Control Screen will light up
(Figure 3). Turn down (CCW)both Encoder knobs (Level controls) to maximum attenuation.
5.
Play a program through your mixer. Set its level to peak at 0 dB or 0 VU maximum on the
mixer meters. Turn up (CW) the amplifier Encoder knobs (Level controls) to the desired vol-
ume (Fig. 3).
