The MMA6000 is a high quality miniature microphone amplifier and
power supply for two DPA miniature microphones.
The MMA6000 is a front-end device that provides two independent
identical channels in one rugged box. The gain settings are made indi-
vidually for each channel.
The miniature microphone amplifier can be operated either by internal 9 V
battery or, optionally, by the use of an external 12 to 30 V DC power
supply. Battery and power supply unit are not included.
A 3-colour LED indicates the power mode:
green (flashing): battery OK;
red (flashing): battery low;
orange (steady light): external power.
The 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 0 dB to 37.5 dB. Please notice the possibility of counter
clockwise switching from 0 dB to 37.5 dB gain.
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.
The attached clip makes it ease to place the MMA6000 on a belt,
strap or bag pocket.
Warnings:
If you want to summarize the two outputs in one cable, only use
DAO0137.
The specifications and tolerances listed, as well as performance and
stability of the MMA6000, are only guaranteed when using the dedi-
cated cables from DPA Microphones.
