This article not only details the operation of the Sign Video ENG44 portable mixer, but also explains many generic concepts about using mixers for video.
A PDF downloadable version is available in the Users Manuals section.
When Sign Video first introduced their portable, over-the-shoulder ENG style mixer, the entire industry was taken by storm. FInally, the financially constrained indy now had access to a full featured, quiet, and properly designed mixer that they could actually afford to own!
However, it soon became apparent that this mixer was going to have a lot of appeal to videographers and sound novices who were not experienced with using mixers.
Hence, the need for a tutorial such as this one, which I originally wrote as an introductory guide for my own clients and students. It not only takes you button by button through the operation of the ENG44, but explains a lot of audio basics along the way.
Batteries
The ENG 44, created by Sign Video, operates from four AA alkaline batteries. Typical battery life is at least a "working day" or more, depending on how much Phantom power your mics draw. The manufacturer quotes 8 to 14 hours of constant usage per full set.
In actuality, you may find that the unit runs even longer, due to real life field variables. For instance, during a real working day, it is normal to turn the mixer off for periods of time in between set-ups. Also, your condenser mics may consume less power than other mics. Or, you may not be using Phantom power at all.
To load batteries, just squeeze the catches, located on either side of the battery door, together and pull the drawer out. Insert four AA alkaline batteries, and re-insert the drawer. It is also possible to utilize rechargeable AA batteries. If you are going to use rechargeables, purchase large capacity batteries of at least 2300ma (2500ma are even better). Note that the ENG 44, when plugged into the AC adapter, does NOT RECHARGE these reusable batteries!
You can also ask your dealer about purchasing an extra battery tray, so that you can keep an instant reload ready to go.
When you power up the unit, the red battery indicator LED will light up. When that LED begins to flash, it means that you should replace your batteries as soon as you get the chance.
Some users have reported that their units continue to operate up to an hour while flashing. Again, it all depends on how much power your mics are drawing.
Powering Up
The On/Off switch is located on the right side (output side) of the mixer, towards the back. When you power up, the red LEDs on the face of the unit will indicate battery or external power source. You can operate the ENG 44 from AC by plugging in the 12v power adapter that comes with the unit.
