Important Safety Instructions FCC COMPLIANCE NOTICE This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause har

19、mful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. NOTE: Thi

20、s equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate r

21、adio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to r

22、adio or televi- sion reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Con

23、nect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help.

Do not locate sensitive high-gain equipment such as preamplifiers or tape decks directly above or below the

25、unit. Because this amplifier has a high power density, it has a strong magnetic field which can induce hum into unshielded devices that are located nearby. The field is strongest just above and below the unit. If an equipment rack is used, we recommend locating the ampli- fier(s) in the bottom of th

26、e rack and the preamplifier or other sensi- tive equipment at the top.

35、ating 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 Crowns IQ System software, see Section 4.5.4. If y

36、ou are going to use SystemArchitect, please follow the information included with System Architect. If you want to load DSP presets or perform diagnostics using the amplifiers 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 l

37、earn about I-Techs many advanced features, please see the rest of this manual. Quick-Start Guide: Stereo Wiring Lets assume that you unpacked and installed your amplifier with the proper cooling. If not, see Section 2 in this manual. Well also assume that you will operate the amplifier in stereo. If

38、 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 amplifiers XLR input con-

39、 nectors. 3. Using Class 2 wiring, connect speaker cables either to the amplifiers Speakon connectors (as in Figure A.2) or to the 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

40、 switch. The LCD Control Screen will light up (Figure A.3). 5. Using both Encoder knobs (Level controls), set Attenuation to 0 dB. Press the Menu/Exit button, then the Next button, to access CH1 Sensitivity. Turn an Encoder knob fully down (CCW) until the minimum dB gain is displayed. Then press Nex

41、t and repeat for CH2 Sensitivity. See Appendix B for details. 6. 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 for CH2. Press Prev and repeat for CH1. Pre

42、ss Exit when done. Note: If the SPL is too high at the beginning of Step 6, press Menu/Exit, then press Next until you see ADVANCED MENU. Push an Encoder knob. Press Next until you see MAXIMUM ANA- LOG INPUT. Press an Encoder knob so the display reads 21 dBu. Press Menu/Exit twice. Press Next. CH1 S

43、ensitivity will be displayed. Gradually turn up (CW) the left Encoder knob to the desired volume for CH1. Press Next and repeat for CH2. Press Exit when done.

Press either Encoder knob to select BRIDGE MONO. Press and hold the knob to confirm your choice. Press the Menu/Exit button. 5. IMPORTANT: Turn off the

48、 amplifier. Unplug its power cord from the AC out- let. The amplifier must be grounded when plugged into AC power. 6. See Figure A.5. Connect a cable from your mixer output to the amplifiers Channel-1 XLR input connector. 7. Using Class 2 wiring, connect the speaker cable either to the amplifiers to

49、p Speakon connector (terminals 1+ and 2+, Figure A.6) or across the red binding posts of both channels (Figure A.5). Do not use the black binding posts in bridge-mono mode. 8. 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). 9.
