Channel 2 Getting Started With I-Tech
Welcome! Operating your 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.
• For bridge-mono operation, see page 5.
• If you want to control and monitor the amplifier with Crown’s IQ
System ® software, see
Section 4.5.4.
• If you want to load DSP presets or perform diagnostics using the amplifier’s LCD control
screen (Figure A.3), see Section 4.2.
You can refer to this Quick-Start Guide to get up and running quickly. To learn about I-Tech’s
many advanced features, please see the rest of this manual.
Quick-Start Guide: Stereo Wiring
Let’s assume that you unpacked and installed your amplifier with the proper cooling. If not, see
Section 2 in this 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 5.
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 A.1. Connect two cables from your mixer output to the amplifier’s XLR input con-
nectors.
3.
Using Class 1 wiring, connect speaker cables either to the amplifier’s Speakon ® connectors
(as in Figure A.2) or to the 5-way binding posts (as in Figure A.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
A.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. Gradually turn up (CW) the amplifier Encoder knobs (Level controls) to the desired
volume (Figure A.3).
