Location: Battle Creek, MI | Just wondering if anyone else feels like the OP pro preamp is pretty weak on output. I have trouble getting good volume from my acoustasonic amp. Am i just imagining it all |

The OP-Pro's do run a little soft when set below 1/2 volume. Try it at about 3/4 and it should be fine. |

no youre not the only one,i have a S868 and it's not doing well om the 012/014 string my luthier say's it's either the pick-up or lack of pressure

Have you tried it through a different amp? I have no trouble at all with mine.
Stick around. Enjoy the group of misfit friends here, and if we're lucky, Temp will come along with answers to any technical questions you might have. |

Location: Battle Creek, MI | I have put in a new battery....as far as amps go, I am using an ultrsound DS4 for practice amp, and the Fender Acoustasonic Ultralight and stereo cabinet for playing out. It is the same on both....just hard to push the amps like I can with guitars with OP 24+ preamps |

Location: Nashville TN. | I had one put in on Standard Balladeer LX with an
OP-Pro Its like 3 times louder through XLR than through 1/4 inch.
The a balanced line in to the fender head.
Why would it not work?? |

Location: Sydney, Australia | XLR is buckets louder than the 1/4 inch on the VIP. I use the XLR at at church because the volume controls on the mixer are locked away and the XLR gives me the freedom to turn it up louder for finger picking. |

Location: Scotland | I've given up on the Op-Pro, low output and a volume pot that doesn't work until it's almost flat out just doesn't cut it.
TAFKAR/Pez, The XLR out operates at mic-level and is actually much lower in output than the line-level jack output. It's the fact than the XLR preamp at the board end is higher in sensitivity that makes the XLR appear louder. |

You can't run a high-impedance source into a low impedance input and expect it to sound good. If you don't own an XLR-equipped guitar and want to use the XLR input on a board you just need to get hold of a direct box. A DI box converts the high-impedance, unbalanced line-level signal from 1/4" jack out to a low-impdance, balanced mic-level signal. It amounts to the same thing as having an onboard XLR output |

Location: closely held secret | That was my point, Paul. You can do it, and it'll be loud, but it will sound terrible. Not to mention having to duck the various objects the sound board operator will be chucking at you because you're overdriving the channel.
I use a DI for the OP-Pro's I have with no XLR jack and have no volume problems. Arlene, you'll probably find a small investment in a DI will solve your problem as well, although if you can afford to upgrade to the OP-Studio (and install, or have installed an XLR jack) you'll find it has other benefits beyond volume.
In any situation where you're more than 12 or 16 feet from the amp or board, you'll want a DI as well. |

Location: SoCal | At church, I'm plugging my 87C, which has an OP Pro with only a 1/4" output, into one of these Radio Shack transformer and then into an XLR jack. As far as I can tell, the sound thru the mains is good...... |

Location: Hot Springs, S.D. | I have a couple of line transformers. These are adaptors with the quarter inch jack on one end and an XLR on the other end. They have a switch for high impedence/low impedence. Would that work going into a board? How about if I wanted to get more volume out of an amp? I have an acoustic amp and a regular old Crate GT30 that I love. Thanks. |

Location: Utica, NY | I agree that without an onboard XLR jack installed that a DI is the way to go. Passive DI's probably won't differ much but I recall that the Countryman DI's were the standard for a long time (in active DI's I believe) and still may be.
But, if I hadn't installed the XLR I was heading to a SansAmp ParaDriver. It was formally the Acoustic DI but this re-work has greater versatility across a range of applications other than just acoustic guitar. I have used nothing but the SansAmp bass DI for my live performances for nearly 15 years with no amp, just direct, with several different basses and it's been spectacular. Our 'electric duo' live setup uses no instrument amplification at all, all directly into the board. The SansAmp Bass DI is a simple, rugged, runs on phantom power (or 9V or adaptor), great customer service/repair service, etc. I would expect no less from the ParaDriver.
The reviews on the ParaDriver are also very good and I may still end up with one. I believe that I have seen them on E-bay in the $150-$180 range at times.
Tech 21/SansAmp makes great, pro quality product that is well worth the money and I would replace mine in a heartbeat should anything happen to the one I have. |

Location: Battle Creek, MI | Thanks for all the input! I think the original point has been lost a bit. I have a S771 Ovation with an OP 24+ and am using a Fender Acoustasonic Ultralight amp and stereo cab for an onstage amp. I am also using a 1778t with an OP Pro preamp and and have problems getting it up to the same volume that I get from the OP24+. Is this a problem with the output of the OP pro and if so, would I be better off to replace it with the OP Pro Studio. Just wondering if any has had this experience with the OP Pro being a bit weak on gain. |
