![]() The original specification was that they wanted the amplifier to go out to 600KHz, but the first prototypes were NOT happy out there and so we 'compromised' at just under 300KHz.Įach channel uses 10 Toshiba 20MHz output devices with a theoretical dissipation of 1,500 watts. Harman wanted this silly specification, why I do not know because we are not bats and cannot hear that high. The amplifiers are flat from DC to 270KHz where the response is about 1dB down. We built a lot of these for Harman International. "We did design and build the Citation 7.1 and the smaller 5.1. Why do you need so much power, did you use the online calculator to figure out what your maximum power need really is? With that info, anything we suggest are pretty much based on guessimates, that is anecdotal at best.Įdit: The ownern's manual's info is a little difference than the service manual's no idea why, but here it is: You can ignore the owner's instruction manual and bridged it to drive your 4 ohms Revel (as it is obviously out of warranty anyway) as long as you are very careful and go easy on your preamp's volume dial, or risk shutdown, even damage to both the amp and the speakers. If the specs tell you it is 400 W into 8 ohm bridged, being an older HK product you should believe it, though I do believe it could do more on the test bench. If it is from online reviewers, I would consider that as unconfirmed, hearsay. A 2.2 kVA 120/80V transformer would likely weight more than 40 lbs, the Citation weights 75 lbs soaked and wet with 4 robust power amps and beefy heat sinks, another indication it wouldn't be 2.2 kVA. 1.2 to 1.5 kVA would seem more believable. Where did you get that info about the 2.2 kVA transformer? I downloaded the service manual, and based on the information in there, including fuse size, I doubt it is that big. ![]()
