1. ## I-Tech Average Power and Voltage Limit Settings for JBL SRX700 Series Speakers

Could You explain why you used 1.25 x the Program Power rating. I thought 1.5 to 2 x the RMS rating was what you use. That would be (2 x 1600 = 3200) x 4ohms = 12800 sq rt = 113.14v. I was just reading up on this and that's what I seem to be finding. I'd like to know if I'm doing this wrong. Thanks, Bob H Hey Bob, Sorry so long to respond, I haven't logged in for a while and just stumbled back on this topic... Typical guidelines for appropriate amp power for use with speakers is .8 to 1.25 of any given speaker's Program Power rating. Usually Program is 2x RMS, and Peak is 2x Program.
2. ## Big question - loads on amplifier

I was running a very small rig this past Saturday for a small venue using a single I-T6000 with a single sub @ 8ohms on one channel, with a pair of tops @ 4ohms (total) on the other. Had a guy who claimed he toured with Clair Bros come by and scold me for mismatching the loads and that it would "blow out" my amp.... Any idea what he was referring to? BTW, he didn't even have a business card...
3. ## I-Tech Average Power and Voltage Limit Settings for JBL SRX700 Series Speakers

BMJ, Finding the peak voltage is a mathematical equation. It is the square root of Watts x Ohms. In your case, the maximum recommended power for the 728's would be 1.25 x Program Power rating (1.25 x 3200 = 4000w) x 4ohms = 16000, then take the square root which = 126.49 Max Voltage. The 722's are (1.25 x 2400 = 3000w) x 4ohms = 12000, then take the square root which = 109.54 max voltage.
4. ## Which Software Do I Need?

I've been using IQwic because that is what originally shipped with the I-Tech's, but now it seems System Architect has taken over as the industry standard. Guess I'll be taking some time to get up to speed on SA for now. Thanks Dave!
5. ## Which Software Do I Need?

Posted this in another section of the Forum, but doesn't seem like much traffic there so... I see many posts with various software applications (IQwic, HiQnet; TCP/IQ & System Architect, etc.) and was wondering which software would best suit my needs. For use with single I-Tech amp, not networking multiple amps. Need to set up presets, but rarely need to monitor amp with PC while in use. Any thoughts?
6. ## Latest I-Tech Firmware?

I have IQwic... Has SA taken over as the most suitable software for the I-Tech's now?
7. ## Latest I-Tech Firmware?

I have an I-Tech amp with Firmware Version 2.122 . I would like to update the firmware in my other amps, however the latest version available on Crown's site is 2.0.9.10 . Where can I find version 2.122? http://www.crownaudio.com/softwaredownload.htm? Current Crown Amplifier Firmware Released April, 2008 Firmware for PIP-Lite, USP3, USP3/CN, I-Tech, CTs4200 & 8200 USPCN * CTs Multichannel USP/CN Version 1.0.7.10 * PIP Lite Version 2.0.9.10 * PIP USP3 Version 2.0.9.10 * PIP USP3/CN Version 2.0.9.10 * I-Tech Version 2.0.9.10

9. ## Outdated Firmware in New Amp?

Thanks Kip. I went ahead and updated my IQwik software to 8.2 and updated all I-Techs to 2.06. I made notes and spent 3 hours re-creating all the presets I previously had prior to the update. One problem... I saved the presets (16 total) to a file and then loaded the file to another I-Tech. Only the first 10 presets would load. Tried again on a different I-Tech with the same result.
10. ## Outdated Firmware in New Amp?

Hey gang, been away from the Forum for a while and playing "catch-up". Just got a brand new I-T6000 w/firmware version: v2.0.5.11 (display) & v2.0511 (DSP). Date code: 0037 I noticed here on the Forum there is a different version (2.0.6.9) listed as the most recent of the firmware. Should I update the new amp already? I'm currently running IQwic v7.20 & Firmware v1.301 on my other I-Tech's. Looks like I need to update my IQwic to v8.20 in order to utilize the recent firmware, correct? Then which firmware version should I update the I-Tech amps to? (v2.05 or 2.06)
11. ## I-Tech: Input Level vs. Output Gain

Hey Dave, Thanks for the response. That would explain the difference between the levels, but now how do I compensate for the gain lost so as not to clip the input, yet increase my output level? Well, it's been over a year since my original post on this subject, yet a solution never was presented & I've been MIA from the Forum for quite a while... Flash forward to today. I receive a new a new I-T6000 and discover a setting for "Bandpass Gain". Happy happy, joy joy!!!!

Check 1, 2... 1, 2... Is this thing on??? *tap, tap*
14. ## I-Tech: Input Level vs. Output Gain

Any thoughts???
15. ## I-Tech: Input Level vs. Output Gain

While monitoring the I-Tech amp in IQwic, I noticed that the Input levels were about 10db higher than the Output even though the attenuators are at 0db. Is this good, bad or indifferent? I'm thinking this condition would clip the *front end* of the amp and that I need to somehow increase the gain to the Output for maximum efficiency, but how?
