Samson D1500 - Manual

ACCESSORIES
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•2500 is a dual channel, 1/3 Octave, 31 Band
Digital Graphic Equalizer featuring cutting edge
DSP and analog-to-digital conversion technology,
together with a simple to use, traditional analog user
interface. The D•2500’s robust, 2 rack-space steel
and aluminum extruded chassis design is not only road
worthy, but it also provides a large front panel layout
which is extremely easy to use and already familiar to
audio engineers. The beauty of the D•2500 Graphic
Equalizer is that it has 31 bands of real hands-on
faders! You may forget that that you are using a digital
EQ; just press the MANUAL button and “look mom,
I’m equalizing the system!” And, with the high-end
24 Bit AD and DA converters and 96K sampling
rate, you’ll enjoy pristine audio quality. Thanks to the
powerful DSP engine and clever software, the D•2500
is capable of producing EQ curves with more accurate
and precise filters, far exceeding the capabilities of
even the best analog equalizers. What you won’t get
is the accumulating additive hiss noise that you get
from an analog equalizer when you push up the high
frequency bands.
In addition to being a simple to use digital equalizer,
the D•2500 is packed with all the goodies including
HIGH & LOW PASS FILTER, NOISE GATE, LIMITER,
ENHANCER, DELAY and FEED BACK MANAGEMENT.
All these digital effects are programmable and their
associated parameters can be stored, and recalled,
as part of the 99 available user pre-sets. The HIGH
and LOW PASS FILTERS allow you to quickly apply
an EQ contour for rolling off the high and low end
frequencies, for example, when equalizing vocal
monitors. The D•2500’s NOISE GATE allows you
to set a threshold level in order to mute any system
hums and buzzes during silent sections keeping your
system super clean. With the D•2500’s LIMTER you
can control the level that you are sending to your
power amplifiers to help you insure good protection
for your loudspeakers. The onboard ENHANCER
will actually add high frequency to the system when
there is program material at those frequencies, adding extra sparkle to the mix. The ENHANCER will also
automatically turn down the high frequencies when there
is no high frequency signal content, which, by eliminating
system noise and hiss, making the D•2500 a very effective
noise reduction system. In addition, the D•2500 also offers
on onboard DELAY for time aligning speakers. Another
powerful feature of the D•2500 is feedback suppression.
The D•2500’s feedback management system can be set
to AUTO which will automatically find the frequency that’s
feeding back and lower the associated filter. Or, you can
use the feedback management system in MANUAL mode
where the D•2500 will automatically find, and then display,
the frequency that’s feeding back, showing which fader you
should pull down manually. All settings and parameters for
the equalizer and digital effects can be stored in 99 pre-set
locations. Using the large, easy to read, LCD display and
convenient data wheel, it’s possible to save your favorite
equalization curves and recall them in the future. Or, when
using the D•2500 together with the D•1500 Real Time
Analyzer, you can auto-correct the room to a flat response,
and then apply your favorite system curve on top. In addition,
the powerful LOAD MASK allows you to recall certain effects
or EQ curves from any preset independently, so you can add
pre-set effects settings with real time changes.
The D•2500 features standard MIDI implementation and
Samson’s D•Net, enabling device-to-device linking for
creating larger audio systems or for interfacing to a personal
computer. When linking the units you see the full power
of the D•Class system. With a basic MIDI connection, the
fader positions of the D•2500 digital EQ can be displayed
on the D•1500 Real Time Analyzer, giving you the power
of digital processing with a unique analog feel. For systems
using many D•Class units, the D•2500 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 D•2500 digital equalizer, D•1500 RTA or
D•3500 feedback management system. In addition 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 preset locations providing instant
recall of your favorite setups. Like all D•Class models, the
