SETTING UP THE D3500
Setting up your D3500 Graphic Equalizer is a simple pro-
cedure which takes only a few minutes:
1. Remove all packing materials (save them in case of
need for future service) and decide where the unit is to
be physically placed—it can be used free-standing or
mounted in a standard 19" rack.
2. Make sure the power to all mixers and amplifiers in
your audio system is off.
3. The D3500 can be used either as an “in-line” device,
as an insert device (in conjunction with mixer insert
points), or in an effects send-return loop. The illustra-
tions on pages 19-21 show each of these typical con-
figurations. Choose the configuration that is best for
your application and then begin by making the D3500
input connections, using the XLR connectors on the
rear panel.
4. Next, make the D3500 output connections, using the
XLR connectors on the rear panel to connect your
power amplifier or active speakers.
5. Plug in the supplied AC cord and connect it to any
standard AC socket.
6 . Press the rear panel Power switch to turn on the
D3500. Press the Filter Select switches in to activate
the equalizer.
Note: if you have the AI02 board installed, the audio signal
will be muted for approximately five seconds until the relay
power-on circuitry is activated (at which time you’ll hear a
click and the audio signal will be unmuted).
Navigating the D3500 Control
Before you move ahead into the many D3500 onboard
effects, you should become familiar with the front panel
controls and the various parameters that they can set.
The D3500 front panel switches are set up in groups relat-
ed to the function or parts of the operating system they
control. Some switches are placed individually, since they
are dedicated to a single function, and other switches are
arranged in groups since their functionality is related. The
D3500 function switch sections are arranged on the front
panel as follows. First, is the BYPASS switch that enables
you to turn the equalizer and all effects on or off. Next is
the A/B switch that lets you compare the actual modified
program to the last program loaded or stored . Then you
will find a group of switches including LEFT, LINK and
RIGHT which are used to assign the D3500's hardware
RIGHT
RIGHT
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. GLOBAL
gives you access to the overall system settings, and MIDI
lets you set up the device-to-device communications
including Samson Audio’s high-speed, D-Net protocol.
Finally, in order to save and retrieve your favorite settings,
the D3500’s LOAD and STORE switches allow you to access
the 100 on-board presets. The following sections of this
manual will detail each of the switches and their associ-
ated parameters. Instead of going from left to right, we’ll
switch up the order a bit for a more logical flow through
the system.
You should know this !
Some switches are capable of accessing more than one
parameter, so as you press the switch repeatedly you will
page through the available parameters. These include the
FBM, GATE, HP/LP, Limiter, GLOBAL and MIDI. For example,
the FMB switch has three pages to click though the param-
eters, Sensitivity, Feedback Hold, Feedback Release. You
can change the parameters of any of these functions by
using the large Data Wheel located by the main LCD dis-
play.
GLOBAL
The GLOBAL control allows you to set up the various sys-
tem parameters including the input option and mode.

Selecting the Input
The D3500 accepts inputs from any of the installed I/O
boards including the optional DIO1 Digital I/O or AIO2,
premium analog-to-digital I/O board. The D3500 auto-
matically senses if a board is installed in an option slot. To
access the input follow these steps:
