$449.97 $661.46

Developed for professional applications on stage or in the recording studio, the Palmer RIVER 2-Channel Passive Direct Boxis a DI box used to pick up the raw signal from a guitar, bass, or keyboard without noise and tonal loss, even over long cable runs. Featuring a dual-channel design, elde can be used either for one stereo instrument or for two different mono instruments. The box's failure-proof, passive circuitry requires no battery.

The 1/4" inputs are each looped to a Thru Out, allowing the signal to be passed on to the guitar/bass amplifier. For those high-level signals, each channel features a pad switch (-30 dB), enabling you to insert the elde between the amplifier output and the loudspeaker without overloading it. The elde outputs low-impedance, balanced signals that can withstand even longer cable runs without damage. Impedance conversion and balancing is done passively via a transformer, which also provides galvanic isolation for less noise. Each channel has its own ground-lift switch to eliminate ground-loop hums. Elde is virtually indestructible thanks to its rugged, aluminum-and-steel casing.

Related Questions and Answers

Q: 1. Can this work on a canon Camcorder?

A: This will work with any camera with a 3.5mm microphone input. I cannot answer your question for your camera exactly because you did not include the model.

Q: 2. What happens when it gets hit with 48v? Will it pass through to the computer?

A: This product is to convert a 3.5mm line level signal out from a computer to an XLR mic level signal. No 48 volt phantom power should be involved in this procedure.

Q: 3. Can I send phantom power in it to power and another device as a pedal that need it ?

A: No, the A-Designs REDDI Mono All-Tube Direct Box with Throughput does not let Phantom Power pass through the device.

Q: 4. Hi! I read the previous question, but The 3/4 of an inch that stick up above the side on the mirrorless unit (v2) is a problem when are inserted in the Shimoda Designs Action X30 backpack? Thank you!

A: Please rephrase the question, not sure what you are asking.

Q: 5. Does the ground lift switch is only for XLR balanced output or for also RCA output unbalanced

A: The ground lift switch is for disconnecting the ground of the XLR jack only from the ground of the DB14b.

Q: 6. The Kopul version of this had a cold shoe mount that was terrible adn would disassemble in the field when the screw fell out of the bottom from too much stress of mounting receivers on it. Does this product suffer the same problem?

A: I worked with Saramonic for 2-years and that whole time, I have not seen any defects of this product, or heard of an issue like you describe. I also have 2 in my possession for those 2-years and had no issue. My best suggestion is to try the item for yourself and if it's not up to your standards, return it for a refund or another product. We also offer a one-year warranty for full replacement if there's any problem. I think you're going to be happy with the product.

Q: 7. What are the sizes of the dividers? I want to use the dividers in my other camera bags.

A: There are no dimensions published for these Shimoda-dedicated accessories, but if you look at the video on the product page, you can see them in use and the size will be apparent.

Q: 8. Are these dividers for DSLR core units or for the mirrorless core unit? Or Does it not matter and the fit both?

A: The size of these are meant for the DSLR core units. They would stick up too far sadly for the mirrorless units.

Q: 9. Does this come with a stereo mini cable?

A: The Saramonic SR-AX101 does include a stereo mini cable.

Q: 10. Can i use phantom power with it to power another device who need it like a pedal whom connect with an XLR connector ?

A: The A-Designs REDDI Mono All-Tube Direct Box with Throughput (BH # ADREDDI) is powered via the included IEC Power Cord. Phantom power is not provided by this device.

[Solid-State] Good stereo passive direct box. Does what it's supposed to. Feels solid, so I expect it to last a while. Exactly what I needed. I will buy more in the future.

[10:1] I wanted to try these Kopul DI boxes out because of the low price. I've used them on a few events already and they work great. The only issue I have with it is that the volume knob feels a little cheap and is wobbly but it doesn't crackle during use. When you buy the DI box, it comes in a foam cutout that is cutout exactly the size of the DI box so I use that to protect the Kopul when I have it in my bag. I would've given it 4 stars because of the knob but I give it a pass because of its low price. The best thing I like about it is that because of the way it's designed, you can plug it into a mixer without needing an XLR cable. I'll probably just buy these from now on.

[Standard DI] Very quiet and acoustically transparent, even on our 120 foot run to the mixer. We purchased 3 of them.

[Standard DI] Headphone jack to XLR adapters are by far the thing that has caused the most issues for me in the audio world with how often they go bad/have a buzz in them. This is great to instantly get rid of any buzz in the line as well as have an additional point of volume control.

[+32 dBu] We are a rock band that plays a lot of large performing arts theaters, and have been using Radial passives.  But after three of those burned out (bad transformers) we thought wed buy inexpensive ones and just replace as needed.  These things ROCK.  Clear, uncolored sound, small footprint, solid metal construction, indistinguishable from the Radials at a fifth of the price. And so far, theyre holding up better than the high priced DI.

[2-Channel] I never expect this would be a great idea. Having 2 channel in 1 box was perfect in our music setup. 1 for guitar and 1 for the keyboard. Works flawlessly and built like a tank. Now the question is how long will this last? Overall it's a great product from DBX and the price is right.
