    Speaker Delay

    What mixer do you use? Delay in principle isn’t hard. Sound travels at around 1ft each millisecond. So, a starting setting for delay speakers can be done by simply measuring how far they are in front of the mains and use that number of ms. Then, with some sound playing (or sometimes I use a...

    QRX212 distortion

    I have a Sabine NAV480 with settings from EV/Telex. At their request I sent them the unit and they used it to establish settings from their reference unit.

    QRX212 distortion

    At a gig a few weeks ago, one of my four EV QRX212s had a high mid distortion. Changing amp channels did not change it nor (on the wild possibility of venue interaction) swapping cab with adjacent cab. Other than the odd distortion, the cabinet seemed to perform ok. So, today I opened up the...

    FS: QSC PL6.0 II amp

    I like passive subs just fine. You only need to connect one cable. In my case, I was able to replace my passive subs with a pair of self powered that suited my needs better and fit my trailer pack better.

    Ethernet Snake?

    I have TMB and like it. How long you looking for? I presume you mean DMX over cat5 or cat6 cable, not actually Ethernet (which isn’t a cable type)?

    FS: Yamaha 01V96

    I find that I just am not using this mixer much any more and am starting to reduce the amount of gear I have as I get older. This is a great Swiss Army Mixer. Amazing abilities in a rack width mixer (no, I don’t have rack ears for it). It is in perfect working order and has been cased since...

    [FS] Yamaha 01v96v2

    I find I don't use this enough to keep it. Great "Swiss Army Mixer" that is incredibly versatile. It has lots of interesting I/O in addition to 12 mic preamps and 4 line in. In good condition. Only used outside a couple of times for weddings. All the rest was indoors. It has been housed in...
