ISP Pro Audio


Here are some frequently asked questions about our products and the answers to those questions:


Q: If my amplifier isn’t powering up, what should I do?

A: First, make sure that your power cord is plugged in to a live, properly grounded outlet. If that checks out, make sure the power switch is turned to the ON position. If the cabinet still doesn’t power up, you may have a blown fuse. Your best bet would be to find out how many watts the replacement fuse needs to be (this information will be located in your product manual) and replace it yourself (if possible) or to call iSP Technologies for further information.


Q: If my amplifier is losing volume, what should I do?

A: This problem may be due to a faulty instrument cable or even a faulty jack in the instrument itself. All cables used in your setup should be checked and inspected for proper operation. Another issue that could be giving you volume problems is that there is an internal decimator built into all of our guitar products. Make sure that the decimator threshold is not turned all the way up or you will not receive any sound. If all of these problems check out, then contact iSP Technologies for more information.


Q: How would I go about getting my speaker cabinet repaired?

A: If you can determine that you are having an internal amplifier problem, you may just remove that part of the cabinet and send it back to iSP Technologies. Please we ask that you write REPAIR DEPARTMENT in bold lettering on the package itself and have enclosed a detailed note, describing the problems that you are experiencing. Make sure to also label and document all connections before you remove them for trouble-free reassembly. Taking a photograph may also be helpful. If you cannot determine what the problem is, call our company directly and we can try and help discover the problem.


Q: Do I have to pay for the repair?

A: If you haven’t already, now would be a good time to familiarize yourself with the WARRANTY that was included with your amp. Within it you will find all the information in regards to what is covered, how long it is covered, and what is required by the purchaser in order to obtain Warranty Service.


Q: If I loose my owner’s manual, how do I obtain a new one?

A: iSP Technologies is currently in the process of putting PDF files of all of our manuals on our website, which any user can visit and download for free. Until that point in time you can email or call us directly and request a new manual.


Q: Where can I locate replacement parts?

A: Call iSP Technologies directly or email us and we will give you information on getting new parts for your cabinet(s).
