Introduction Congratulations! You just purchased one of the most innovative and useful audio tools available to sound engineers today, the D3500 Dual 15 Band Parametric EQ / Feedback Management System. The D3500 is an advanced parametric equalizer featuring cutting edge DSP and analog-to-digital conversion technology, together with a simple to use, traditional analog user interface.
D3500 Features ������ ������ ����� ������ ���� ��� ����� ��� ������ ������ ��� The Samson D3500 Digital Parametric Equalizer / Feedback Management System utilizes state-of-the-art, DSP and filtering technology for precise tonal and feedback control. Here are some of its main features: • • • • • • The D3500 is a sophisticated digital equalizer combined with an advanced, and easy to use, automatic feedback management system providing 30 bands of parametric filters.

Controls and Functions 23 LIMITER switch – This switch is used to page through the LIMITER parameters. When selected,the amber LED will illuminate and the LIMITER parameters will be displayed in the LCD window. 26 GLOBAL switch – When engaged, the red LED will illuminate indicating access to the unit's GLOBAL parameters. 27 MIDI switch - This switch is used to page through the MIDI parameters. When selected, the red LED will illuminate and the MIDI parameters will be displayed in the LCD window.
Setting-up the D3500 RIGHT which are used to assign the D3500's hardware controls to operate the Left, Right or Left and Right EQ channels. RESET is the next switch and it allows you quickly clear any selected filters, returning them to the 0dB Gain position. The next section is where you will find the D3500’s powerful onboard digital loudspeaker processing effects, which are controlled by the FBM, EQ, GATE, DELAY, ENHANCE, HP /LP, LIMITER and IN/OUT switches.
Setting-up the D3500 If you want to use the D3500 as a dual mono equalizer and control the Left and Right sides individually, keep the LINK switch OFF so that the green LED is not lit. • Press the GLOBAL control switch once or twice until you see the Inp. Controlling the Right Channel signal If you want to control the EQ and the effects for the right channel individually, make sure the LINK switch is OFF.
D3500 Quick-start Quick start – Using the D3500 to Reduce Feedback The D3500 is a powerful 30 band, fully parametric equalizer with onboard loudspeaker processing effects. Each of the 30 filters can be manually set and all the effects parameters can be adjusted and stored into memory. However, if you want to use the D3500 as a simple automatic feedback management system, you can.
D3500 Quick-start • Now, select filters 11 through 15 by pressing and holding the Channel 11 Filter Select Switch, and then press the Channel 15 Filter Select Switch. At this point you will notice that the green Selection LEDs for the filters 11 – 15 are lit. This indicates that the filters are ready to be set-up and engaged. • To set these filters to DYNAMIC mode, press the EQ switch until MODE is displayed in the main LCD. • Use the Data Wheel to select Mode 2; (DYNAMIC).
Operating the D3500 Using the Filter Control Knobs The D3500’s front panel features a hardware control section with encoder knobs that allow you to make quick real time adjustments to FREQUENCY, BANDWIDTH and GAIN for any of the 30 filters. You can adjust any filter that has been set by an internal preset using the Filter Control Knobs. You can also operate a filter in MANUAL mode and use the Filter Control Knobs to quickly set the EQ band by hand, and by ear.
Operating the D3500 • Use the Data Wheel to select Mode 3; (RESONANCE). Using the LEARN Mode The following example is for reducing feedback in a typical PA system used by a band in a small to medium size club using the LEARN feature. You will set ten of the filters to RESONANCE mode to remove problem frequencies that have to do with microphone and monitor placement, as well as room acoustics.
Operating the D3500 Adding Dynamic Filters • If you have not set the RESONANCE filters to remove feedback problems that occur due to microphone and monitor placement, as well as room acoustics it is a good idea to do so by following the previous section, “Using the LEARN Mode”, to set filters 1 - 10.
Operating the D3500 • To access the Feedback Sensitivity parameter, press the FBM switch until you see the menu, FBM: Sensitivity. The Feedback Sensitivity is used to set the threshold that the D3500 uses to recognize feedback. Now you can select a Sensitivity of 0 – 10. This parameter affects both the Resonance and Dynamic filters. • To access the Feedback Hold Time parameter, press the FBM switch until you see the menu, FB: Hold.
Operating the D3500 Once the highs return, the Enhance releases automatically. Of course the D3500 lets you dial up just the right amount of Enhancer for your project, so follow the steps below to activate the Enhancer. • To access the Threshold parameter, press the GATE switch until you see the menu, Gate Th. The Gate Threshold can be set from –100 dB to 0 dB. • To access the Release parameter, press the GATE switch until you see the menu, Gate Rel.
Operating the D3500 The HP / LP Switch Has Four Clicks! Click Menu Function Value 1 Lowpass high Cut Filter 2 kHz - 20 kHz 2 Lp-Order Filter Slope 0, 6, 12, 18 per Octave 3 Highpass low Cut Filter 20 Hz - 200 Hz 4 HP-Order Filter Slope 0, 6, 12, 18 per Octave Using the LIMITER for Basic Speaker Protection In order to help you protect your speaker system, the D3500 employs a digital Limiter. When engaged, the digital Limiter will prevent signals from reaching outputs levels over a desired point.
Operating the D3500 Storing Programs in the D3500 The D3500 has 99 memory locations (labeled 01-99) for storing user presets. You can save the equalization curve, as well as all the parameters for the routing and the onboard effects that may be active. Saving the preset is a simple procedure which is accomplished with the following easy steps. Using the Load MASK function The D3500 allows you to mask certain saved parameters when loading in a preset.
Operating the D3500 MIDI and D Net For expanded system control, the D3500 uses standard MIDI, as well as Samson’s D Net communication protocols, to transmit and receive digital control information to and from additional D class units, other MIDI devices, or personal computers. You can use standard MIDI cables for IN, OUT and THRU to configure a system using traditional MIDI protocol.
Operating the D3500 Now that you have enabled the D3500 for D-Net, as described in the previous section, you can select additional MIDI parameters that may be necessary for your exact application or system set-up. The D3500’s MIDI has three basic modes of operation Channel, Omni and System Exclusive and Program. The D3500 can operate in any of these three MIDI modes. • In order to set the D3500 to receive system exclusive messages, use the Data Wheel to select SysEx. Rc. Press store.
System Configurations Using the D3500 with Active Speakers In this example, the mixer’s stereo output is connected to the D3500’s inputs. Then, the D3500’s outputs are connected to the inputs of each active (self-powered) loudspeaker. Using the D3500 with Passive Speakers In this example the mixer’s stereo output is connected to the D3500’s inputs. Then, the D3500’s outputs are connected to the input of a 2channel power amp.
System Configurations Using the D3500 into Insert Points You can use the D3500 in your mixer’s insert points if you want to equalize two mono channels individually in the mix. In this example the D3500’s Channel 1 INPUT and OUTPUT are inserted on a bass guitar channel using a 1/4-inch TRS to 2 x 1/4-inch TS “Y” cable, and the Channel 2 INPUT and OUTPUT are inserted on a keyboard channel using the same type of cable. For more information on cable wiring see the D3500 Wiring Guide page 22 in this manual.
In this example, two D3500’s are used for the stereo main and for the 2-channel monitor mix. The mixer’s left and right outputs are connected to the first D3500’s inputs for the main PA speakers. Then, the outputs are connected to the inputs of the power amplifier connected to passive loudspeakers. For the monitor mix, the mixer’s AUX1 output is connected to the second D3500’s channel 1 input and AUX2 output is connected to the channel 2 input.
