XLR Adapter Menu

The XLR-BP™ Pro is an XLR audio adapter that allows you to connect  professional audio equipment, audio mixers and professional microphones to your video camera or DSLR camera.

You can run long balanced audio lines and have superb noise free audio with this XLR audio adapter. The XLR-BP Pro™ will work with video cameras, DSLR camera, camcorders, digital recorders and any other recording device with a 1/8" microphone input jack.

The XLR-BP Pro™ has features such as, an auxiliary 1/8" mini jack and a 1/4" jack that can be used as balanced or unbalanced input, a true ground lift switch, with a lightweight design and improved audio performance.

Our audio quality is the best. We use custom made transformers for better frequency response.  In addition, our XLR audio adapters do not suffer from insertion loss and high frequency cutoff as other XLR audio adapters do.

Tthe XLR-BP PRO™ case is shielded against both EMI & RFI interference. Only our XLR audio adapters military specs level of shielding. Our XLR audio adapter case provides total shielding to the entire circuit inside. In addition, each custom transformer is also properly wrapped multiple times with an EMI & RFI shielding material for superior shielding.

Our XLR audio adapter offers two locking XLR inputs, a single 1/4" input and a single 1/8" mini input.  This gives you total flexibility with your audio connections. You can use any two inputs connections at a time, in any combination. Each of the two audio channels has its own volume controls and mic/line level input selection switch. Input 1 and 2 can either be recorded as separate audio tracks or mixed together, depending upon how you have the Stereo/Mono switch set.

We use only custom pro grade audio transformers in our XLR Audio Adapters.  We use pro grade audio pots, switches and other components through out the XLR Audio Adapter.  All components are mounted to a circuit board. The end result is an XLR audio adapter with superior audio performance and extremely quiet operation.

We use pro grade Neutrik locking XLR connectors. This prevents the XLR cables from pulling out of the XLR audio adapter.

The XLR-BP™ Pro XLR audio adapter clips onto you belt for when you are hand holding the camera and it can be clipped on camera's hand strap when you have the camera mounted on a tripod.  The XLR Audio Adapter comes with a 4 ft. shielded audio cable with a stereo mini plug so it can plug into your camera's microphone jack.

The XLR-BP  Pro™ Features:

  • Two XLR Balanced Inputs - Featuring Neutrik XLR jacks with locking connections. This ensures the XLR cables don't pull out.
  • A Single 1/4" Input (can be used with balanced or unbalanced inputs)
  • A Single 1/8" Mini Input
  • Nickel-Based Lined Shielded Case - Provides a superior EMI & RFI shield rating and meets military specs.
  • High Quality Shielded Transformers - Offer virtually no insertion loss and superior frequency response. Each transform is wrapped multiple times with a shielding material that protects against both EMI & RFI for noise free operation.
  • Stereo/Mono/Mix Switch:
    The mono position allows you to have one microphone input record on both the right and left audio tracks.

    The stereo position allows input 1 to record on the left audio track, with input 2 recording on the right audio track.

    You can use the XLR-BP Pro™ in a mix mode, this allows you to mix input 1 and input 2 together and record the mixed inputs on both the right and left audio track.
  • Mic/Line Level Selection - Each of the two channels have a mic/line level switch.  This gives you the choice of microphone level input or line level input from an audio mixing board, for each input channel.
  • Voltage Block Circuit - This circuit is necessary as the mic jack on some video cameras actually outputs 2.5 to 3 volts of power.  This can be a source of noise and it may cause problems with some types microphonese. All of our different XLR-BP's have this circuit.
  • Ground Lift Switch - The XLR-BP Pro has a ground lift switch for eliminating any ground loop hum in the audio. A ground lift switch allows you to break the ground connection between two devices, thus eliminating common ground loop problems. This is critical when connecting to various audio equipment, such a an audio mixer board.

    Please Note: The ground lift switch is not a ground selection switch.  A ground selection switch simply changes the ground path to the camera, thus keeping the ground loop problem present. (Plus, on some video  cameras this switch useless)
  • Audio Level Controls - We use only professional grade audio pots.  Each input channel has it's own audio level control.
    Note: If your camera has an AGC (automatic gain control) circuit and you find yourself using two mics, the AGC will take the strongest or loudest  input and lower it to an acceptable level. This can cause the other input to be very weak. By using the audio level controls, you can turn down the strongest input to balance it to the other input level. Resulting in better audio levels on both audio inputs.
  • 4ft Shielded Cable - The XLR-BP Pro™ has a 4ft shielded audio cable with a right angle 1/8" stereo plug on the end.  The 1/8" plug is used to plug into the video camera or DSLR camera or anything other recording device's microphone input jack.
  • No Power Required - Passive device.
  • Lightweight - The XLR audio adapter is lightweight, so you won't have a heavy box pulling down on your belt or pocket.
  • Works with all video cameras with a microphone jack. Also, works with, digital audio recorders, DAT, mini disc recorders and other audio recording devices.
  • Ideal for use with microphones, Line Level Inputs (such as on a audio mixer) or externally phantom powered condenser microphones.

Customer Comments:
"I love your XLR adapter box.  I had mine for 8 years now and it is still going strong.  I am writing you today, because I am ordering a second one for my son to use, as he is joining me in my business.  I have done a lot of business with you over the years and your products have never let me down.  Keep up the great work."  Darin Moore, Long Beach, Ca.

"I saw a guy on YouTube using your XLR-BP Pro in one of his videos.  He gave it a great review, so I decided to order one.  I totally agree with his review which was, "If you want great audio, this is the best XLR adapter to use."  I like the fact that you can clip it to your belt or you can clip it on the strap on the video camera."  Lucy Fields, email.

"I order the XLR-BP Pro, wow did it arrive fast.  I have been using it for a few months now and I am really happy with it.  It works great with all of my microphones and the audio quality is outstanding.  Not only do I use it with my video camera, I use it with my computer for connecting up XLR mics to it.  This is a must have product for any videographer who is serious about sound quality."  Patrick Summers, Long Beach, CA.

"The XLR-BP PRO is really a great audio device. Took it of Africa on a 3 week shoot, shot in all kinds of conditions, it held up great. The XLR-BP Pro gave us perfect audio every time. I was very pleased to see that is was so lightweight and yet so durable. (We accidentally dropped from the roof of a truck while breaking down our gear). The XLR-BP Pro is worth every penny we paid." Jan Von Roza, Island Film & Video

"A colleague was shooting a small indie film when his sound guy, Tim, broke his foot on the second day of production. I was asked to step in and takeover for him. Tim was using your XLR-BP PRO to feed audio into a VX-2000. Both of us were amazed at the superb sound quality we were getting with our mics feeding through XLR-BP PRO. Not once did ever encounter any noise problems. I have work in the audio field in LA for the last 18 years and I would like to say this is a great product. I would highly recommend to any filmmaker. I just ordered one through your website for myself." JR Corman

"After using my new XLR-BP Pro for the last week, I can say with all certainty that I will recommend this product to all of my colleagues. This is far superior than my (under the camera model). I use to have problems connecting to my Mackie audio mixer with my old (model). Got a constant ground loop hum. Now when I connect up using the XLR-BP Pro and setting the ground lift switch to "lift" I great clean sounding audio. The XLR-BP Pro is a great improvement of my (old model)." Charlie Cox

"To anyone who uses a Steadicam or a Steadicam type device: Get the XLR-BP Pro. It is the only adapter that really allows you to use XLR audio mics and keep the Steadicam balanced. No jury rigging, no modification, just clip the XLR-BP Pro on your belt and go. This is a terrific product." Carlton Hammond, Steadicam Jr Owner.

"Wanted to let you folks at Studio 1 that your Super Jib Arm and the XLR-BP are terrific products. That past week we mounted out GL-1 on the Super Jib Arm and connected the XLR-BP to the GL-1. It made it so much easier for us to have the XLR-BP with the audio controls clipped to our pocket, whereas before we couldn't reach the audio controls when the camera was up in the air. Also, the Super Jib Arm has opened us up to a how new level of creativity. Thanks for the great products and keep up the good work." L. Robert Kinder, Internet Email.

"Every time I opened the LCD screen I was getting noise in my (under the camera) adapter. I found that by moving it about 6 inches away from the camera the noise would go away. After asking around on the web, I was directed to your site by another guy who had the same problem. I ordered the XLR-BP Pro and I tested it upon receiving it. Works great. No noise what so ever, even when I hold it under the camera! Thank you for building an excellent product." Karl Hench, Rockport, Ill.

"The XLR-BP PRO deserves an A+. After putting it through tests both in-house and I the field the XLR-BP PRO offers excellent sound quality, no noise problem when running the camera from A/C power or battery. The ground lift switch was a great idea. I’ve had problem when interfacing your old XLR adapter to my audio mixer, but after testing the XLR-BP PRO with the ground lift switch my problems are gone. The versatility of the unit, the easy access controls and it‘s solid construction make this the best XLR adapter I‘ve own." S. Lee Bonner

"The XLR-BP PRO not only gives great audio, but it even takes a beating! I was shooting a special interest video on BMX biking. During one shot I was riding on the tailgate of a pickup truck just shooting action shots of the bikers. I had my shotgun mic and XLR-BP PRO laying beside me. We hit a hard bump and the XLR-BP PRO and mic flew off the tailgate and both took a hard hit. The mic didn’t survive, but the XLR-BP PRO did and only suffered a few scratches. We continued to use the XLR-BP Pro while shooting the rest of the video. Even after taking a beating, we got prefect audio. You got my vote for product of the year." Oscar Rameriz

"Great product! I really like the design of your new XLR-BP Professional. The sound quality is fantastic and there was no noise when I connected it up to different mics and mixers to test it. I am currently working on a production and I am using it daily with great result." Bruce Farnsworth, Hollywood, CA.

"I purchased the XLR-BP Professional and wanted to report, this is one of the best purchases I ever made. Very quite, very clean audio, well thought out placement of the controls and very noise free. I have put my (old xlr adapter) up for sale, as your new XLR-BP Pro is so much better." Lee Wong
