Sound Devices 664 Powering Options Tutorial
There are various powering methods in the Sound Devices Powering Options. This quick tutorial will guide you through how to power your mixer/recorder and the system menu for Sound Devices Powering Options.
I personally use and recommend getting an external power supply powering option. I use a SWIT NP1 style battery that is 14.4v and 73Wh. The Swit is then mounted in a Harkwoods horseshoe to 4pin DC connection for the Sound Devices 664 Powering.
The internal battery options are best utilised with WORN DOWN plastic on 2500mAh batteries and above. By all means try sand paper to lightly take off the coating but BE CAREFUL and DO AT YOUR OWN RISK. Mine got worn down through lots of use naturally.
WARNING: DONT FILE YOUR BATTERY PLASTIC COATING OFF AS YOU MAY CAUSE A LEAK FROM THE BATTERY OR SIMILAR.
Sound Devices 664 Powering Options Battery Life:
The battery life of the 664 varies depending on the number of inputs activated, phantom power used, number of recorded tracks, correct powering options selected and general usage. Running 1-3 radio mics and 1 boom on phantom power I get around 1-2hrs from internal batteries (2500mAh) with switching on and off between scenes. My SWIT 14.4v external battery can give me all day power for a 8-10 hour day with switching off over lunch break and occasionally during long setup times.
I recommend buying a combo pack so you have two SWIT batteries and you can easily last 14 hours without a break and hot swap (Switching to internal power and swapping external batteries and then switching back to external powering) for greater flexibility and never having a moment when you run out of power. Keep an eye on your internal Voltages though: 13.5 is very low for EXT and 4.5 is very low for INT.
Thanks for your support.
