MMA6000 Miniature
Microphone Amplifier
The MMA6000 is a high
quality miniature microphone amplifier and power supply for
portable stereo recording, designed for use with all DPA miniature
microphones.
For professional and hobby recording applications in the field, on
stage or at home the MMA6000 is an indispensable tool, offering a
higher sound quality than the microphone input on most portable
devices and providing the extra security needed to feel completely
safe and self-sufficient in any recording situation.
The MMA6000 is a front end device that provides two independent
identical channels in one rugged box. Inputs are fitted with
MicroDot connectors. These connectors also provide the supply
voltage for the microphones. The gain setting is obtained by a
16-position switch providing steps of 2.5 dB in the range from from
0 dB to 37.5 dB. A low cut switch-in filter (common for both
channels) inserts a 12 dB/octave,100 Hz low cut. The output is a
3.5 mm stereo mini-jack connector.
Five dedicated quality cables for various recording devices and
applications are available as accessories.
