Visit our Battery Module FAQ for more info on why you would want to use a battery module. For owners of newer Sony MD recorders that do not have mic input sensitivity switches, a portable microphone preamplifier found here would be a better solution.

Mini Deluxe Battery Module

The mini deluxe battery module is a super small microphone power supply. It provides the same level of power as the larger battery modules, without the larger size. The components are encased in a tough material which protects them from reasonable wear and tear.

This battery module is recommended when you need the high SPL qualities of a set of mics with a battery module, but don't have the space for a regular sized module. Available with short 3" output cable for use in an Otter Box system or other small mic case or with normal length 24" output cable.

The Deluxe model has no bass roll off (bass reduction) and is recommended where the material to be recorded has only moderate bass content, or where the mics used with it have their own bass roll off.

Built-in level controls
The level control option is mounted completely inside the Metal or Slimline battery modules. It is most useful with MiniDisc recorders that don't allow adjustment of recording levels while recording (most SONY MD recorders).

This optional feature provides two individually adjustable slider controls that adjust the output of the microphones before going to the recorder. The user simply sets the record level ONCE on the recorder at (or near) full gain and adjusts the recording levels with the built in output level controls at any time during the recording. The actual recording level is still read on the recorder's level meters.

Features:
- Controls are mounted inside Metal or Slimline battery modules-no increase in size!
- Recommended for use with Sony MiniDisc recorders, camcorders and other recorders that can't adjust recording levels on the fly (while recording).
- Utilizes high quality Alps slider controls

The Metal and Slimline battery modules utilize a standard 9 volt battery (included) which will last approximately 300 to 500 hours, depending on the microphone used with them.

Aside from their physical size and case material, there is no difference between the different versions of the Metal and Slimline battery modules. The same high quality components are used in their construction. The standard output connectors of the battery modules are right angle stereo mini plugs.

For those recorders that do not allow the user to change recording levels while recording, such as the SONY MiniDisc portable recorders, or where it is desired to be able to adjust each channel's recording level independently, we offer optional microphone output level controls.

This option is available on many of our battery modules (see details above). This feature provides two individually adjustable slider controls that adjust the output of the microphones before going to the recorder. The user simply sets the record level ONCE on the recorder at (or near) full gain and adjusts the recording levels with the built in microphone output level controls at any time during the recording. The actual recording level is still read on the recorder's level meters.

The controls (one for each channel) are high quality "Alps" slider controls, similar to what you might see on a small studio mixer or graphic equalizer. See picture section at top of page for photos. Adding the level control option does not increase the size of the module.
