The Cable Techniques MX-POWERSLED is designed for use with the Sound Devices MixPre-3 and MixPre-6 field recorders. It sports a Hirose 4-pin connector that attaches to the devices, supplying 7.2V to the recorder once it is connected, and accepting a DC input range of 9 to 24V from compatible, rechargeable batteries such as Li-ion NP-1 or smart batteries. As such, this device obviates the need for AA batteries and battery sleds, as well as the need for USB power. The former can often cost more money in the long run, while the latter doesn’t necessarily provide a secure enough connection for moving about in the field— obviously, no one wants to lose power in the middle of a shoot. Lightweight at 3.2 oz, the MX-POWERSLED can integrate into DC distribution systems, and can complement a bag rig replete with recorders, wireless receivers, and more, all powered by a single host.

Thank you for your question. It will depend on size of battery and the amount of channels you are using with phantom power.

Is this compatible with the newer versions of the Mix Pre series? I have one, it works well with the Mix Pre 3 v1 but doesn't seem to seat correctly on my Mix Pre 6 II
Asked by: Michael
As a better option for the MixPre-6 II, you could use the Sound Devices MX-LMount Battery Sled (B&H # SOMXLMOUNT) which is available in stock.

will this work with Mix Pre 3 II which is rated at 5V?
Asked by: Geoff
Yes the Cable Techniques MX-POWERSLED will work fine with the MixPre 3 or 6. The recorder regulates the voltage required not the battery sled.

If the MX-Powersled is attached to a Mixpre 6, will it still fit in the K-Tek Stingray bag made for the Mixpre? Or, do you need to jump up in bag size to the K-Tek Junior?
Asked by: Chris
I think you would need a bigger bag what with the 12 volt external battery

If I got this for a MixPre 3 and a Hirose 4-pin to D-Tap/P-Tap cable, would I be able to power it off v-lock batteries with a D-Tap/P-Tap out?Also, If it was to be configured under a camera with v-lock power could it split and share power to both devices or is there load limits, etc?Trying to run it off a RED Raven, but also have the ability to power it separately off v-lock batteries.
Asked by: Simon G.
Question #1) Yes, that should work fine. The MX-Powersled has a large input voltage range of 9 to 24 volts DC, and can accept power from any source that can be wired to the four pin Hirose DC standard, and supply the 7 to 9 watts the Mixpre 3/6 requires. I have used mine with an NP-1 cup to Hirose cable, AC adapter, as well as a car battery alligator clip cable with no problems. Question #2) There should be no issues with sharing a battery between both devices (with a commensurate decrease in overall run time). As indicated above, the Mixpre 3/6 needs about 7-9 watts to run with phantoms on all inputs, less without phantom.The Mixpre-3/6 is a fantastic piece of equipment that is extremely flexible and great sounding. Good Luck!
