Aux fed subwoofers have become a very useful tool for the audio engineer in the last several years. There are two main reasons for using aux fed subwoofers. Each of them is beneficial to the other.
1. Using Aux Fed Subwoofers gives the engineer more control over the relative Low Frequency SPL.
2. Using Aux Fed Subwoofers allows the engineer to keep inputs with little or no LF content out of the subwoofers for a cleaner, more intelligible mix.
With modern pop music and EDM music, the engineer must be able to control the relative level of the Subwoofers in relation to the full range speakers. Since much of this music is highly compressed with almost no dynamic range the excessive LF content can easily distort or even cause damage to the subwoofers. By using Aux Fed Subwoofers, the engineer can make adjustments as needed to maximize the output without detriment to the system. Since much of the audio requires the subwoofers to be as much as 20 dB louder than the full range speakers it is often necessary to lower the LPF on these applications to maintain an accurate Acoustic Crossover. We’ll address this in future tech tips. For these applications the Aux Fed Subwoofers can derive their signal from either a Post Fader Aux output or from a Group output.
For many engineers running sound for bands keeping the microphones out of the subwoofers makes the mix sound much better with more accurate sounding vocals. In these applications the engineer uses a Post Fader Aux to send only the inputs that need Low Frequency reproduction to the subwoofers such as Bass, Keyboards, Kick Drum and Floor Tom. By doing so, the engineer does not have to use as high of a HPF on the vocal mics which leads to a nice, warmer sounding vocal. By keeping the inputs out of the subwoofers that don’t belong there the system runs more efficiently, as the subwoofers and amplifiers are not wasting power reproducing unwanted signals.
With three inputs and six outputs, the X-Drive makes for a very versatile Loudspeaker Processor which is perfect for operating Aux Fed Subwoofers. Each of the three inputs can be routed to the six outputs individually. Each output has four band Parametric EQ plus HPF and LPF to optimize your settings.
This picture shows an example of how easy it is to route the inputs to the correct outputs for Aux Fed Subs using the XD360.
KEY BENEFITS OF AUX FED SUBS
* Better Vocal Quality
* More control over LF output
* Less wasted energy
* Clean mixes
* Easy processing with Carvin XD360 Loudspeaker Processor and Carvin X-Drive Amplifiers
It is with deepest sadness that we announce that guitarist and Carvin artist Shane Paul Gibson passed away at 5:45 AM on April 15th, 2014 in the UAB Hospital in Birmingham, Alabama as a result of complications from a blood clotting disorder. He was 35 years old. Shane was a long-time member of the Carvin family, having conducted numerous clinics, appeared multiple times at NAMM, and performed with Carvin gear on stages around the world for countless fans. He was a very talented and gifted musician, and his virtuosity was matched only by his wit and generosity. He will be missed beyond measure, and we take solace in knowing that his spirit will live on through his music and fans.
Shane's final recording with his band stOrk, titled "Broken Pieces", was just released this past Monday, and showcases his talent and skill, and will be a fitting memorial to Shane's legacy as one of the preeminent guitarists of the hardcore/punk genre.
Our thoughts and prayers go out to his family, friends, bandmates and all those who loved him as much as we did.

Carvin’s new Acoustic Series amplifiers offer state-of-the art performance for the serious acoustic artist. Matching the aesthetic of your acoustic instrument, the rich natural tones are delivered from heavy-duty drivers accompanied with a titanium tweeter that provides exceptional full-range performance – from shimmering, crystal-clear highs to full bottom end. The high headroom internal amp maintains the purity that only high power can provide. So whether you’re using nylon, steel, gut, silver or silk-wound strings that are picked, plucked, strummed or bowed, the true fidelity of your instrument is faithfully reproduced.
Channel 1 and 2 inputs are specifically designed to work equally well with piezo or magnetic pickups, and feature a HI-Z impedance switch to bring out the full tonal range of passive pickups. A GAIN switch matches low sensitivity pickups. The +48V phantom power switches on Channels 1 & 2 eliminating external power supplies required for condenser mics, active pickups or active direct boxes. Channel 3 may be used to mic an instrument or vocals, and the 1/8″ jack serves as an input for your MP3 music source. The onboard dual digital signal processors offer lush effects for each channel featuring echo delay, reverb and chorus.

The Master Effect 1 & 2 controls select the effect type, adjust time, decay, regeneration and speed settings with separate level controls for blending effects 1 & 2 into the overall mix.
Other features include a USB power port, XLR direct out with level control, headphone/tuner jack, external effects loop and external extension speaker connection.

Rave reviews continue to come in for Carvin’s new PB Series electric basses, and the latest is from Bass Player Magazine. They say, “Happily, the PB5 has a killer B string that receives ample coverage from the pickup, and has a tight, defined acoustic response that makes it very playable, even in the higher positions. There was a time when you had to go with a premium boutique build to get this kind of B string at 34″ scale, but Carvin seems to have figured this one out a long time ago. The PB5 can produce a wide range of tones from the P-Bass spectrum – from thumpy Jamerson to grindy Entwistle, and it manages to “look right” without being a cookiecutter copy. Carvin’s overall fit and finish is top notch, and with the savings of dealing directly with the factory, you can step into a U.S.-built 5-string for under a grand. Pretty sweet.” Follow the link below to read the complete review.
Carvin’s PB4 and PB5 basses can be custom-ordered with a multitude of options, including body, neck and fingerboard woods, highly figured premium top woods, dozens of finishes, a wide selection of inlays, different fretwire sizes in nickel and stainless steel and an assortment of pickup and electronics options suitable for any playing style. Check out the PB Series for yourself, and see why these new basses are the
talk of the industry!
