GENERAL DESCRIPTION
The MM01 is a fixed charged condenser microphone
designed especially for critical test and measurement
applications. Manufactured with extreme care, superior
electronics and the highest quality craftsmanship, the
microphone delivers an exceptionally clear, accurate
sound, with precision pattern control. The MM01 is a
perfect compliment to any Real Time Analyzer, such
as the D•1500 Digital RTA from Samson Audio. The
microphone exhibits an extremely flat frequency response
providing accurate results when measuring individual
drivers or complete sound systems. Thanks to it’s low
noise and linier frequency response, MM01 can also
be used for miking acoustic instruments, or as ambient
room mics for studio recording applications. In addition,
the high SPL capability and omni-directional pick-up
pattern makes the MM01 an excellent choice for a variety
of specialty miking applications in live sound situations.

GENERAL DESCRIPTION
The D•1500 is a powerful and accurate audio
measurement device with 31-bands of real time
frequency analysis. What would once take you hours
to do, can now be performed in minutes. And the
result, your audio system is set to a true, sonically flat
frequency response, or to your own custom pre-set
response curve that you’ve stored in the D•1500’s
internal memory. This process is simplified with
the D•1500 thanks to its large LED display, (which
is extremely easy to read in any live sound setting)
simple user interface and powerful equalization
correction algorithms when connected to a D•2500.
In addition to the RTA, the D•1500 includes a Phase
correlation meter, VU level meter, and a Signal
Generator capable of producing White or Pink Noise
as well as a tunable Sine Wave. The D•1500 includes
a balanced microphone input, with phantom power,
that will work with just about any test measurement
microphones, although we recommend a microphone
with an extended and linear frequency response such
as Samson’s MM01 measurement microphone. The
D•1500 features standard MIDI implementation or
Samson’s D•Net, enabling device-to-device linking
for creating larger audio systems or interfacing to a
personal computer. When linking the units you see the
full power of the D•Class system. With a basic MIDI
connection, you can have the D•1500 RTA display
the fader positions of the D•2500 digital EQ, giving
you the power of digital processing with a unique
analog feel. For systems using many D•Class units,
the D•1500 can be fitted with the DN1 D•Net network
card. Samson’s D Net is a high-speed communication
protocol for connected multiple D•Class units, like
the D2500 digital equalizer. In additional to being
10 times faster than MIDI, the error rate is so close
to zero, it’s difficult to measure. All settings and
parameters can be stored in any of the 99 user-
preset locations providing instant recall of your
favorite setups. Like all D•Class models, the D•1500
features an advanced 32-bit point floating processor
DSP interface to high quality converters with 24-bit audio
resolution and sample rates up to 96kHz for pristine audio
quality. You can even upgrade your D•Class units to premium
Analog-to-Digital and Digital-to-Analog I/O (Input/Output)
converter boards, keeping your D•Class system up to date
with the best technology, and sound, far onto the future.
FEATURES
> 31-band, Digital Real Time Analyzer accurately measures
the frequency response of any sound system.
> Large frequency LED display plus custom, back-lit Liquid
Crystal Display for easy readability in any live sound
environment.
> The RTA has adjustable meter Resolution that lets you
zoom in and out on your measurement, and adjustable
Frequency range for RTA allowing you to make tighter
measurements.
> On-board Phase Correlation meter.
> The D•1500’s display can be converted to a large VU Level
meter that simultaneously displays both Peak and VU levels.
> A comprehensive Signal Generator capable of
producing White and Pink Noise, as well as a tunable
Sine Wave can be used to flatten a system with a
standard analog equalizer, or automatically with the
D•2500 digital equalizer.
> RTA mode lets you see the frequency response of your
system in real time.
> EQ mode configures the LED Meters to display the fader
positions of up to 16 connected D•2500 Digital Equalizers.
> Pristine audio quality thanks to the high quality Analog-to-
Digital and Digital-to-Analog I/O audio converter boards
with 24-bit resolution and sample rates up to 96kHz.
> XLR Balanced Microphone Input with phantom power for
connecting a measurement microphone.
