using an 8 ohm speaker. The only audio
which is amplified comes from the ‘left’
sources (mixer and repeater). The wiring to
‘bridge’ the amplifier is a little different from
what you might be used to on a linear
amplifier. The speaker is wired in parallel to
both speaker outputs as shown in the
drawing, and the ‘Stereo/Bridged’ switch on
the bottom of the
Sd-25
is moved to the
‘Bridged’ position.

DMX-512 Inputs:
If you are using the Sd-25 with any
Gilderfluke & Co. controller other than a
Br-miniBrick4
, you will want to trigger and
control the Sd-25 via the DMX-512
connection. This has several advantages:
• Instant access to any of 255 SoundFiles stored on the Sd-25
• Normally uses just one DMX-512 address
• Does NOT use any of the controller’s digital outputs
• Your Sd-25s are Automatically configured & programmed by
Pc•MACs. You just put markers on the timeline in your shows
where you want SoundFiles to start, and Pc•MACs
automatically does all the work for you:
• Automatically programs in the sound triggers
• Automatically creates a folder for each Sd-25 used with
all the SoundFiles and settings in it. You just drag-n-drop
the contents of this folder onto your Sd card for the

Sd-25s, and set the Sd-25’s DipSwitches as shown on

• Supports virtually any number of Sd-25s, each with their

• Optional volume control using a second DMX-512 channel
The DMX-512 connections are through two
RJ-45 connectors. These are the eight
position, eight conductor plugs typically used
for ethernet cables. They are also used for
DMX-512. The pinout of the DMX-512
connectors follows the USITT wiring
standards:

The two DMX-512 connectors are wired in

‘input’ or the ‘thru’. You can easily daisy

Whenever it is receiving valid DMX-512, the
Sd-25s
will toggle its DMX-512 LED on each
packet received.
If the DMX-512 is coming from another piece
of GilderGear, it will automatically sense and
start using the GilderCheckSums. These
prevent the
Sd-25s
from triggering on any
corrupted DMX-512 packet.
If you plug the
Sd-25’s
Rs-232 port into a
computer and fire up GilderTerm (or any
other terminal program), it will display the
current DMX-512 mode, DMX-512 address,
if DMX-512 is being received and if
