electronic version of our warranty statement is available here (Adobe Acrobat, 90kB). The warranty on JBL Professional loudspeaker products (except for enclosures) remains in effect for five years from the date of the first consumer purchase. JBL Amplifiers are warranted for three years from the date of original purchase. Enclosures and all other JBL products are warranted for two years from date of original purchase.

Yes, however you must be able to pass the speaker signal from your amp through the Cabbone and then to the two sets of speakers. Most high-end combo amps will be equipped to do this.

Providing you are using the Marshall recommended speaker lead and that this is replaced on a regular basis you should not notice any loss of quality due to the speaker lead. The noise you are describing is due to the distance you are from your amplifier the louder you set your amplifier the greater this distance needs to be, this will also depend on the pickups in your guitar.

This depends on several things - price, power, weight, and, of course, personal taste. My feeling is that combos are good up to about 300 watts or so. Beyond that, they get to be too heavy to lug around, and too bulky to fit in the trunk - or even the back seat - of the average automobile (I'm assuming, of course, that you will be lugging your own gear around all by yourself).

For the best speaker damping and least amount of power loss you will want to use the heaviest gauge that is practical. The length of the speaker wire should be considered when considering wire gauge. The shorter the run, the smaller gauge you can use with minimum power and damping factor loss. The longer the run, the heavier gauge you will need to minimize power and damping factor loss. You will also want to consider the size of power amplifier you are using.

The following discussion will focus on practical facts on speaker cabinet stuffing and on sealed systems. Theory is limited help in selecting speaker stuffing. Vented system do share a few of these same issues and will also be mentioned, but the goals and physics of stuffing a vented box are different than those of a sealed box. NHT speakers use polyester fill. Some use a Danish polyester that mimics the properties of fiberglas very closely.

SWR recommends using a stiff brush (such as those used for cleaning dishes) to keep SWR cabinet carpeting free of lint and dust, although the best way to keep your cab clean is to get an SWR cover. Waterproof covers made from high-quality Cordura are available for most SWR products and may be ordered through your local SWR retailer. Drastic temperature changes can effect speaker performance, so exposing your cab to very cold weather for extended periods of time is not recommended.

No. Using instrument cables to connect your speakers can result in intermittent power loss, amp oscillation and speaker damage, as well as rendering the cables useless for any purpose. We recommend using 18-gauge or heavier speaker cables.

There is a big difference between guitar amp use and PA or HiFi use of speakers, and in some areas the advice and issues are almost exactly opposite-- but both correct in their given areas. In HiFi and PA use you must never let the amps clip. Once you do the amp will begin to deliver significant amounts of energy in relatively high frequencies. A PA of a HiFi rig will have high frequency drivers, whose power handling capabilities are by necessity vastly lower than those of the bass drivers.

I have no Home Theater setup. The ORION can certainly be used for a Home Theater, especially when the THOR subwoofer is added. My primary interest is music reproduction and the arrival of discrete multi-channel audio in the form of SACD and DVD-A was driving me to investigate the center channel issue. I have reported on my findings and have no pressing need for either center or surround speakers.

During a call, press the Monitor softkey, then hang up the handset. (You will be able to hear the call, but you will not be able to talk on the call.)

Any Ampeg amplifier with a solid state output (SVT-4PRO, SVT-3PRO, SVT-350H, B-5,4, and 3R) can be used for recording purposes using only the line output to record and without speakers attached to the speaker jacks. The amp must have a speaker load if the amp has a tube output section (SVT-CL, SVT-2PRO, and V-4B), not doing so can result in extensive damage to the amplifier.

Connect a secondary speaker output from your amp or your speaker cabinet to the SPEAKER INPUT on the rear of the U5.

Yes. Just make sure you match the amp and speaker impedance so that the amp sees a proper load. If you are not sure about loads, have a look at 'Using the Cabbone' here or consult your dealer for assistance.

GenTech provides full 42U cabinets for shared and private use. Cabinets are ventilated and are enclosed on all four sides. Please click here for additional cabinet colocation information.

If it's a tube amp, this is the worst case version of the above impedance mismatch and will destroy something in your amp's output circuitry really fast - probably your output transformer (NOT cheap to replace), and maybe more. Never, ever do this. I don't care what anyone else ever tells you, don't do this.

As detailed in 'Using the Cabbone' on this web site, in situations like this, you have to make decisions based on manufacturer specifications and your desired tone. If your amp manufacturer does not recommend connecting speakers below 8-Ohms you will have to change your speaker cabinet to accommodate this. It is always best to consult your Tonebone dealer as he can help you set up your system for optimum performance. Try changing the 'switch mode' on the Cabbone from momentary to latching.

There are many factors to consider when thinking about laser vision correction. Once evaluated at our office, we like to refer our patients who are interested in corrective laser surgery to Colorado Laser Surgeons (www.coloradolasersurgeons.com) because they are very stringent in their screening process and will let you know if they think you are a good candidate based on your eye health, prescription and expectations.
