2Foreword
The G Sub 1001 dp+ is a multi-functional premium class subwoofer with an integrated digital ampli-
fier providing 2x 500 Watt @ 4 Ohm (AES) and a DSP controller. The 10” long-excursion driver is
powered by one of the amplifier channels, and the other channel is available to power external
passive loudspeakers connected to the SpeakON out connector. According to requirements, mid-
high systems (e. g. TS Nano or i4) or an additional subwoofer (e. g. G Sub 1001) can be con-
nected. Various pre-configured presets and level settings are available for selection.
The integrated DSP controller is based on the same operating principle as the stand-alone control-
lers HDLM 8 and DSP 2.6. A mere 0.8 ms latency (from analogue input to output) is achieved
through the use of a 96 kHz sample rate. The excellent signal to noise ratio is a further feature of
the DSP controller. Electronic simulation of a transformer balanced input provides additional pro-
tection against hum and buzz caused for example by external interference. High grade electronic
components from the industrial sector and first-class circuit design result in a robust device with
excellent audio characteristics and minimize disruptive noise.
The default state of the integrated DSP controller is the standard configuration as described in this
manual. Custom presets can be installed by the user, but must be programmed with the LPI (Loud-
speaker Programming Interface) by the manufacturer. The preset file is a custom audio file which is
simply played into the audio input of the controller. In this manner, individual configurations can be
created, for instance to accommodate the specific requirements of an installation project. Further-
more, should you ever be unsure as to the integrity of the DSP configuration of your controller, you
can obtain a fresh default file from SEEBURG acoustic line and re-install the original factory pre-
sets yourself. Efficient and intelligent limiter functions provide optimal protection without sacrificing
any of the potential of the system.

3Safety instructions
Acoustic
Even a low input level can result in a sound pressure level at the
loudspeaker which can be damaging to your hearing. Do not remain
in close proximity to the loudspeaker when it is being operated. Use
hearing protection. Observe all relevant Health and Safety and Envi-
ronmental Protection regulations.
Mechanical
Movable parts and falling objects during installation and de-rigging
can cause serious injury. Observe at all times all relevant Health and
Safety regulations and regulations on the installation and operation of
PA systems.
Magnetic und electrical
Loudspeakers generate a magnetic field even without a source of
power connected. This can damage or destroy magnetic storage
devices. The PowerCon loop-through connector is under power when
the device is in operation. Observe all relevant safety regulations at
all times.
General safety precautions
The installation and de-rigging of this equipment should only be car-
ried out by appropriately qualified and experienced personnel, and
according to all relevant safety regulations. Find out about the appli-
cable regulations in the country you work in and comply with the re-
spective regulations.
Do not operate the loudspeaker if you have any doubts about the
safety of doing so, or if the loudspeaker shows any signs of faulty
operation. There are no user serviceable parts inside the device. For
repairs, contact your dealer or a qualified service technician.
The loudspeaker is a class 1 device requiring a 230 V / 50 Hz power
connection with earth contact.

If the loudspeaker is connected to a power source in which the volt-
age is too high, a protective mechanism is triggered which reliably
safeguards the amplifier module and DSP. Once triggered, the pro-
tection must be renewed by a qualified service technician.
Never open the housing. There are no user serviceable parts inside.
Do not expose the loudspeaker to rain, and avoid operating in envi-
ronments below -5° C or above 40° C. Be aware of the possibility of
condensation forming inside the housing due to rapid changes in
temperature. Allow the loudspeaker to adjust to ambient temperature
before operation. Leave the device switched on if operating in unfa-
vorable conditions.
To prevent overheating, do not operate the loudspeaker in the direct
vicinity of strong heat sources, and avoid direct sunlight. After long
periods of operation, the loudspeaker, particularly metallic compo-
nents such as the pole mount and the connector panel, can reach
temperatures exceeding 40° C.

4.2 Connectors
XLR connectors (1)
The G Sub 1001 dp+ should be connected with a standard symmetrically wired XLR cable. To
connect the input signal to further devices, use the male XLR Loop thru connector. To obtain full
power performance from the system, the signal source should be able to provide a minimum of 6
dBu distortion free output voltage.
PowerCon blue (2)
Power supply input voltage 110-230 VAC. This connector provides the function of an on-off switch.
After powering on (turn the connector to the right until it locks), the systems starts up and is ready
for use after approximately 3 seconds. Avoid repeatedly switching the system on and off, particu-
larly when it is operating.
PowerCon grey (3)
110-230 VAC loop-through connector. This connector is to be used when multiple active loud-
speakers are to be provided with power from one source. Please observe carefully the maximum
power capacity of the power source.
The nominal power consumption of the G Sub 1001 dp+ under full
power is 0.75 A (measured with pink noise, Crest Factor 8). Transient
peaks can, however, cause much higher momentary power drain.
Observe carefully the nominal power consumption when connecting
the loudspeaker(s) to the power source, and observe carefully the
cut-off current of the safety circuit breakers. We recommend using the
loudspeaker on power circuits with circuit breakers with C characteris-
tic.
SpeakON black (4) –Parallel LS output
This connector is used to connect and power a further external G Sub 1001 from the first amplifier
channel parallel to the built in loudspeaker (pin assignment 2+/-). The output signal from the se-
cond amplifier channel is present here on pins 1+/- to enable the implementation of system cabling.
ATTENTION!The total impedance of the connected passive systems must be 8 Ohm or more! It
is highly recommended to not connect more than one passive G Sub 1001 to this output.

SpeakON black (5)
This connector is used to connect additional passive loudspeakers to the second amplifier channel.
Presets are available for selection for various high-mid systems (e. g. i4, L16, TS Nano or TSM8)
or two additional G Sub 1001 units (switch to Bi-Amp mode). The output signal from the second
amplifier channel is present on both 2+/- and 1+/-.
ATTENTION!The total impedance of the connected loudspeakers must be 4 Ohm or more. When
the preset “2 x Low” is selected, no more than 2 passive G Sub 1001 units should be connected.
When a “Low-Hi” preset is selected, only mid-high systems should be connected.

5.1 Starting up
When the system is switched on, it retains the settings from the previous usage. This also applies
to the Bank selection. The system is then in the Status Mode . If the red Mute LED is lit as a
result of the previous setting, no signal will be passed. Pressing the Set button once will un-mute
the system. The Mute LED will go off, and signal will be passed.
5.2 Selecting a bank
The loudspeaker presets are stored in the DSP controller in up to 3
banks. To change banks, press and hold the Mode button whilst the
loudspeaker is switched on.
1. Press and hold the Mode button.
2. Connect the power cable (PowerCon blue).
3. Corresponding LEDs blink to indicate the chosen bank.
4. Release the Mode button.
When the power cable is connected, the level and/or preset LED
lamps blink to indicate which bank is selected. The level LED blinks
to indicate the first bank, the preset LED for the second. The third
bank is indicated by both LEDs blinking.

5.3 Setting level
Pressing the Mode button once selects the Level Mode, in which you
can adjust the output volume in 3 dB steps. There are four settings
available: +3 dB, 0 dB (standard), -3 dB and -6 dB. The setting is
done by pressing the Set button. The Level LED lights to indicate
which mode is activated. The four vertically aligned LEDs (lit green in
this mode) indicate which setting is selected.
ATTENTION! The level settings apply only to the first amplifier
channel which powers the in-built loudspeaker and the parallel
LS output (SpeakON socket (4)).
5.4 Recalling presets
Pressing the Mode button twice selects the Preset Mode. Three different presets with an each
switchable Cardioid Mode are available in each bank for selection via the Set button. The four ver-
tically aligned LEDs indicate the current selection. The Cardioid Mode is activated in the preset
when the bottom of the four vertical LEDs lights up.
5.4.1 Preset Bank 1 –Default Settings
Low --- Hi:
Preset for use when the second amplifier channel is powering a mid-
high system (e. g. A4 or TSM8) connected to SpeakON socket (5).
The acoustical cross-over frequency in this preset is approx. 120 Hz.
Low --- Hi:
Preset with a higher cross-over frequency for use when the second
amplifier channel is powering a smaller mid-high system (e. g. A1 or
TS Nano) connected to SpeakON socket (5). The cross-over fre-
quency in this preset is approx. 160 Hz.
2x Low:
Preset for use when the second amplifier channel is powering further
passive G Sub 1001 units (max. 2 units) connected to SpeakON
socket (5).

Cardioid Mode:
The so-called backward attenuation of a subwoofer system (combina-
tion of at least 2x subwoofers) can be significantly increased with a
cardioid. The cardioid function works regardless of the choice of three
possible presets. If this mode is activated, the G Sub 1001 dp+ and
the subwoofer connected to the parallel LS output are in Cardioid
Mode. The connection does not change the SpeakON socket (5) what
means that up to two passive front-facing G Sub 1001 can be con-
nected (when using the 2x low preset). More details in section 5.7.
5.4.2 Preset Bank 2 –L-series
Low --- Hi:
Preset for use when the second amplifier channel is powering an
L16i/j system connected to SpeakON socket (5).
Low --- Hi:
Preset for use when the second amplifier channel is powering an L8i/j
system connected to SpeakON socket (5).

5.5 Reprogramming of dp-speakers with preset audio files
By default, the built-in DSP controller is in a default configuration state that conforms to the descrip-
tion in the User Manual. The installation of special presets on the DSP controller can be done by
the user himself, since only a special preset audio file must be loaded. The programming of these
audio files via the LPI (Loudspeaker Programming Interface) can only be done by the manufactur-
er.
The preset is getting installed on the DSP by playing the preset audio file in the XLR input. This can
be done in different ways (MP3 player, smart phone, PC, CD player, ...). Installation via PC is done
as follows:
1. Use a mini-jack-XLR (stereo) cable to connect the headphone output to the XLR input of
the self-powered box. Use only one of the XLR connectors.
2. Mute the box by pressing the Set button in Status Mode. The Mute LED lights up. The
DSP controller can only receive data in the muted state.
3. Make sure your computer's volume is set to 100%.
4. Load the ".wav" file received from SEEBURG acoustic line into a music player.
5. Press the play button.
6. After a successful programming operation, the Mute LED turns off.
It is very important to ensure that the preset audio file is played in
single mode. Other music files in the playlist or on the data storage
medium will otherwise be played at full volume.
5.6 Locking the buttons
Press and hold the Set and Mode buttons simultaneously for more
than 3 seconds to lock the controls of the system. Repeat the action
to unlock the system.

5.7 Cardioid Mode
The Cardioid Mode serves to generate a cardioid response pattern for the subwoofers. Using this
mode, a significant reduction in bass energy emission to the rear of the system can be achieved. A
minimum of 2 subwoofer units is required. Multiples of three is better. Specialised signal processing
creates controlled interference patterns between the sources, leading to the desired cancellation to
the rear.
In order for the interaction between the sources to function correctly and generate the desired car-
dioid response, the subwoofer system must be set up at least 1.5 m away from any bordering sur-
face such as a wall or solid stage front.
Installation using two subwoofers:
The G Sub 1001 dp+ that is in Cardioid Mode must be positioned such that the front of the unit is
facing the rear, whilst a second G Sub 1001 dp+ which is not in Cardioid Mode faces the front as
normal. The level of the rear-facing G Sub 1001 dp+ must be reduced by 3 dB compared to the
front-facing subwoofer if the cardio system consists of only two subwoofers.
Note:
Both subwoofers must be set to the same cut-off frequency. The cardioid preset of rear-facing
subwoofer must be activated and the level has to be reduced by 3 dB.
Application example:
Only the rear-facing subwoofer is operated in Cardioid Mode. This applies regardless of whether
the two units are stacked on top of each other or laid
side by side on the ground.
e. g. G Sub 1001 dp+
120 Hz, not in Cardioid Mode, Level 0 dB
G Sub 1001 dp+
120 Hz, Cardioid Mode, -3 dB

G Sub 1001 dp+
5 Operation
15
Installation using three subwoofers (recommended):
The performance of the cardioid configuration is better when 3 subwoofers are used together. The
units can be stacked on top of each other or laid side by side on the ground. If in a stack, the low-
est unit should face the rear. If laid side by side, the middle unit faces the rear.
As in the previous example with two subwoofers, the rearwards facing subwoofer is operated in
Cardioid Mode. The two forwards facing units are operated as normal without the Cardioid Mode
activated (e.g. one G Sub 1001 dp+ with a passive G Sub 1001 connected to the parallel output
SpeakON (4) and the Cardioid Mode not selected). All of the subwoofers in the configuration
should be operating at the same level and with the same cut-off frequency to get the best result.
Note:
Both subwoofers must be set to the same cut-off frequency. The cardioid preset of rear-facing
subwoofer must be activated.
Application example:
Only the rear-facing subwoofer is operated in Cardioid Mode. This applies regardless of whether
the two units are stacked on top of each other or laid side by side on the ground.
