for G Sub 1801 dp /
G Sub 1802 dp

The output of the G Sub 1801 dp and G Sub 1802 dp subwoofers has been increased from 2400 watts to 4800 watts by installing a newly developed amplifier module.
This has increased the final level
by around 3 dB!

12.2023 Software update S-Series power amplifiers

Software Update

S-Series power amplifiers

The comprehensive software update for the S-Series power amplifiers is available for download:

OCS software package/ current firmware
>> Software OCS_Setup_V 4.2.6 (zip)

Updated speaker library
>> Speaker Library V 2-11 (zip)

Updated hardware manual
>> Hardware Manual V 1.2 (pdf)



  • As very extensive adjustments and changes have been made to the signal flow and links in the software and firmware, it is necessary that the snapshot library and the speaker preset library are also updated. These are included in the ZIP file of the download package.

  • Snapshots created by the user may no longer function correctly and may need to be recreated!

  • If you have created your own speaker presets, these must be exported individually and saved on the computer before the update. These can then be re-imported into the new preset library.


> SEEBURG OCS v4.2.4

  • Power button now with 1 second switch-off delay to prevent accidental switch-off
  • Currently selected amp highlighted in colour and easier to recognise
  • Display of activated EQs improved
  • Improved operation when setting the quality in the EQ window
  • The bandwidth (BW) for EQ filters is also displayed in addition to the Q value
  • Bug fixes to the control groups and their synchronisation
  • An amplifier could still be edited in OCS although it is in standby, deactivated (offline editing and synchronisation will come in a future version)
  • Devices can be found in the network and their IP can be set via the "Ethernet Config" menu
  • Improved visualisation of the signal flow
  • Designation of the modes more comprehensible
  • Input matrix implemented
  • Simplified selection of input sources
  • Switchable backup input with automatic switching between primary and secondary
  • The devices in the device list can now be reordered by clicking and dragging


> Firmware v.3.1.5

  • Value range of the nominal Ampgain corrected to 26-44dB
  • Erratic occurrence of "Dante" as input source fixed
  • Adjustments to support the S20 model
  • Encoder behaviour improved
    (less "jumping" values)
  • User EQ page simplified
  • Allpass filter added to user EQs
  • Peak limiter time constants were not loaded correctly, corrected
  • When loading a new speaker and after reset, the outputs are muted for safety reasons
  • Input matrix implemented
  • Simplified selection of input sources
  • Switchable backup input with automatic switching between primary and secondary
  • Length of the device name increased to 14 characters
  • Fixed sporadic connection problems via USB


> Neue Snapshot Library v2.0

with customised basic snapshots according to the new capabilities


1) Download and install the new OCS software package v4.2.4 (also contains the latest firmware!)

2) Connect Amp via USB

3) Switch Amp to standby mode

4) Press and hold encoder and switch Amp on again (display shows that bootloader is ready)

5) Start "SEEBURG Firmware Updater" in Windows, click on "connect" and start update. Once the update is complete, the power amplifier restarts itself and is ready for operation.


1) Start OCS

2) Find the amp in the device list and double-click to open it

3) Use the menu buttons "Open Snapshot Library" or "Open Preset Library" to load the new libraries onto the power amplifier.

After updating the libraries, it is advisable to reset the amplifier or load the first basic snapshot "Direct Out".

11.2023 24. SEEBURG Hausmesse 2023

in-house exhibition

on 13.11.2023

Our 24th SEEBURG in-house exhibition
was a complete success with around 150 visitors.

The presentation of our new products, the very well-attended presentations, the exciting exchange with colleagues and the professional and personal discussions once again made the in-house exhibition a great experience.
Many thanks to all visitors for this successful in-house exhibition.


Interesting lectures:
Power specifications in sound reinforcement technology: What is actually defined?
Presets and tuning of PA systems: Approach and steps to optimization

Product presentations
C 15 / C 30 and C Sub:
The new "Constant Curvature Line Array" closes the gap between point source systems and line arrays. Optimized performance thanks to three 1" drivers with an enlarged 1.7" coil in a very compact design.

GL 16 Sub dp+:
Now also available in the self-powered version. 3 x 6.5" subwoofer extension
for GL systems

i5 dp / i4 PoE:
Self-powered variants

Martin Keller and Johannes Nocker are guests with the new ALLEN & HEATH AVANTIS SOLO and the small "all-rounders" of the CQ series.

10.2023 C-Serie - C 15 / C 30 / C Sub


C 15 / C 30 / C Sub

• Constant Curvature
• Full scalability
• Highly precise dispersion
• Compact appearance
• High performance

The new "Constant Curvature Array" loudspeakers C 15 and C 30 combine the advantages of point source speakers with the performance of Line Arrays.

The vertical dispersion is being defined by the addition of the single C-Series speakers. With the C 15 and C 30 there are vertical dispersion angles of 15° and 30° available.
With relatively few elements, even larger audience areas can be sounded very precisely and equally. The applications are in theatres, sports arenas, club sound reinforcement and medium-sized open air concerts.

C Sub - Bass extension for the C 15 and
C 30 Line Array. Integrated and visually unobtrusive flying system for flown array applications in fixed installations.

in-house exhibition

on November 15, 2021

After a one-year break, our 22nd SEEBURG in-house exhibition on November 15th, 2021 became an event with many exciting innovations, to which visitors from the fields of event technology, performing arts centers and system integrators were invited.

Product highlights:

Four state-of-the-art 4-channel system power amplifiers S3 / S5 / S10 / S20 in performance classes ranging from 4 x 600 watt to 4 x 4800 watt. During development, particular attention was paid to innovative ease of use, high efficiency, sound quality and reliability.

PS 1 / PS-Sub: High performance 2 x 12” / 2 x 6.5” / 1.4” horn loaded highmid system and 21” subwoofer. The system, which is particularly suitable for clubs and discotheques, can also be used very well in ​​sports venues, theme parks and for live events.

i Beam: Loudspeaker arrays with beam steering technology with many interesting features such as sound guidance using dedicated waveguides, audience area based beam calculation software and presets that can be called up directly on the device. The columns, equipped with a 3" broadband speakers, impress with their high tonal precision, even in the high-frequency range, and are therefore also suitable for high-quality music reproduction.

GL 16 Sub: 3 x 6.5" subwoofer extension for GL systems.

Insight into the latest development studies: Self-powered miniature loudspeakers with Dante and PoE; Constant Curved Array speakers C 30 and C 15 with 30° and 15° beam angle and powerful 2 x 10" / 3 x 1" components.

Experience loudspeakers up close, talk to our SEEBURG team and exchange experiences with colleagues - ingredients that made the event a valued industry get-together again.

Many thanks to all visitors and SEEBURG users for this successful in-house exhibition.
