    OK! I'm old fashioned and all i have ever used is 1/4 in speaker cables.
    Just got my new 9.2 in today and was wondering if anyone could tell me if the speakon connectors are the type you can also use a 1/4 inch plug with?

    if not...can i buy such an adaptor as my current cab is 1/4 only? i'm at work and have not had the time to READ the manual yet.
    Thanks for any help

    You can get a speakon to 1/4" cable. You may also be able to find an adapter, but I haven't seen one those. Enjoy the new amp!

    If the jack is green, it can accommodate a quarter-inch plug. Otherwise, go with the adapter RFR recommended above.

    I have one, and tried to do it. Its speakon only. Adapter is the way to go.

    Changing the cabinet to SpeakOn is the way to go. :D

    Don't use an adapter.

    Get a 1/4" to Speakon cable or swap the jack in the cabinet.

    IIRC, shorting the speaker cable on any SMPS amp(like your 9.2) can let out the magic smoke - which definitely makes a compelling argument for going speakon only on both ends... IMO/IME, once you get used to using speakons, you won't want to go back to 1/4"...

    I've used speakon to 1/4" cables many times - just be aware of what "can* happen, and act accordingly...

    What's the problem with using an adapter? And why would a properly used 1/4" cable present a short circuit?

    ^That's my question. I do use speakons on both ends, but have adapters on some 1/4" cables as backup.

    When using 1/4" plugs, be sure to turn the amp off when making and breaking connections.

    An adapter requires the use of two 1/4" connections, instead of just one - truth is, I don't view ANY 1/4" connections to be a good thing in regards to a bass cab speaker circuit, so one is better than two, IMO... After all, 1/4" connections cannot carry as much current(wattage) as a speakon - including one where it isn't necessary can't be a good thing...

    A 1/4" plug can create a short if it becomes unplugged - I'm sure we've all seen that - whereas a speakon doesn't do that... I switched over to speakon only a few years ago, and have never regretted the decision for a second... I made up a couple of 1/4" to speakon cables "just in case", but almost never use them...

    Also, see Andy's response above mine - alot of people don't do that 100% of the time...

    I play it all. Whatever works for the gig. Q+
    Speakons are the way to go.. At times i wish the Genz had the Dual type that also take the 1/4". But accidents do happen.
    My SM9.2 is in a 4 space SKB with my DBX unit that i use for my larger gigs with two cabs... My crew packed my amp and left the cables ( speakon to 6ft cable to 1/4' end) attached to the amplifiers outputs..
    I was on a club gig two days later and only brought one cab with me.
    I plugged in the DI XLR, the power to the wall and one speaker cable to the one cab, but left the other cable stowed away inside the rack but still connected .. (forgetting its a 1/4" on the end of the stowed cable).
    I turn the amp on.. And it thumped as it went into protect mode and the protect light was flashing .. At first i didn't realize what was going on..
    My big mistake !!!!
    What happened was the 1/4" opened end of the stowed cable was touching the metal chassis or rack rails shorting the output..

    I unplugged the cable and turned the amp on again . All was fine. the GB protect circuitry really does work well and fast.. !!
    Ive told Andy that if i cant break it no one can! HA

    My amps get used in many situations, small gigs to huge rooms and many miles and crews handling it.. as well as myself / and things are bound to happen every so often.. .. and so far ive never had a failure. Knock on wood..
    Im glad the Genz protection works as good as it does.. My amp is still going strong.. Had 5 shows on it since.. Not one issue

    When unplugging a 1/4" plug from the speaker end, the tip and sleeve can short together inside the sleeve of the jack. Common cause of failure for some (mostly older) amps.

    I figured those were the issues. For the uneducated I could see where that might be a problem... I consider them operator errors and as such avoidable. I use 12 gauge 1/4" cables with nice ends, only make/change speaker connections with the power off and don't have my rig where someone including myself could get behind it and accidentally disconnect my three foot cable. My 1/4" cable is a lot heavier duty than my speakon to 1/4" cable. I haven't had any issues using my bridged Crown Drivecore XLS1500 with heavy duty banana to 1/4" cable with or without a speakon adapter. How much wattage can a short quality 12 gauge cable carry?

    For a bass rig, I don't see a real problem... because an avoidable accident often isn't one. It's a mistake. So I carry and use banana, 1/4" and speakon equipped cables so I'm ready no matter what.
