Product
The Active Tuning Module for floorstanding speakers was developed for all full-range speakers, including small models such as the nuBox 483 or the nuLine 244. It can also be used to acoustically optimise speakers from other manufacturers. The active tuning module activates unused reserves in the bass range and also enables precise sound control of the bass, mid-range and treble.
We have designed the ATM compact speaker for bookshelf speakers, wall speakers and other smaller speakers.
Nubert tuning modules are not mass-produced goods, but are manufactured with great care and mostly by hand, which is why they proudly bear the "Made in Germany" label.
Only high-quality, specially selected components are used to guarantee the extremely high dynamic range of 124 decibels. This guarantees maximum signal purity and eliminates harmful sound influences by integrating a tuning module into the playback chain. The active tuning module is housed in an elegant brushed, black anodised aluminium casing.
The functional principle of the active tuning modules
The cabinet volume of a speaker influences the bass response. To put it simply: the smaller the speaker, the lower the bass response - even if the built-in drivers could in principle reproduce lower frequencies. Günther Nubert's remedy: If the cabinet "slows down" the bass reproduction, the amplifier has to "step on the gas" more in the lower frequencies.
To enable the amplifier to activate these reserves, the active tuning module forces it to provide more power in the range affected by the level drop, thereby shifting the lower cut-off frequency of the speaker. This audibly improves the speaker's bass performance. At low listening levels, a kind of "loudness effect" can be achieved with this clever circuit.
The second advantage of the active tuning modules is the convenient sound control. With the help of precise rotary controls for the bass range and the mid and high frequencies, the playback spectrum can be optimally adapted to personal taste or tuned to the listening environment or recording. The basic character of the piece of music is retained because the treble or bass is evenly intensified or reduced and not "bent" at certain points, as is the case with conventional tone controls or inferior equalisers.
Installation of an active tuning module
Active tuning modules can be integrated into a modern playback chain in two ways: either between the player and amplifier or between the preamplifier and power amplifier. The first option works almost everywhere as long as the amplifier and player have analogue cinch inputs or outputs. Depending on the ATM version, up to three source devices can be connected in this way and selected via a rotary selector switch on the module.
The second type of connection is particularly suitable for stereo systems in which separate preamplifiers and power amplifiers are used. Some integrated amplifiers that can be "split" internally or have monitor inputs are also suitable for this type of connection. Please note: This type of integrated amplifier is becoming increasingly rare; AV receivers equipped in this way have almost completely disappeared from the market. If you have a highly integrated system such as a network receiver without corresponding connections or use players that only offer digital outputs, you cannot use ATM with these!
Nor can Active Tuning Modules be connected to the loudspeaker outputs of an amplifier.
If you are interested, please consult our advisory team to determine the optimum connection type for your system!

Risk of Injury or Damage!
When moving the device, exercise caution to avoid injuries or damage!
Caution!
As this device can only be completely disconnected from the mains by unplugging the power supply, it must be positioned to ensure easy access to the power supply. If any of the following conditions occur, immediately turn off the device and disconnect it from the power supply. Contact Nubert electronic GmbH (info@nubert.de) without delay:
- The device or power supply has been damaged or dropped.
- The power cord or plug is damaged.
- Objects or liquids have entered the device or power supply.
- The device has been exposed to excessive moisture or rain.

Use only accessories recommended by Nubert!
Placement Instructions
Caution!
An unstable placement can lead to damage to the device.
- Place the device only on a flat, stable surface and ensure it cannot be knocked over!
- Ensure that no accidental pulling on the cables can occur to prevent the device from being pulled down or damaging the connection ports!
- Avoid exposing the device to strong mechanical shocks!
Caution!
Excessive heat buildup inside the device or power supply can shorten the device's lifespan or cause a fire.
- Never cover the device/power supply or its ventilation openings! Ensure sufficient clearance and air circulation around the device/power supply.
- Do not operate the device/power supply near heat sources such as radiators or stoves!
- Do not expose the device/power supply to direct sunlight!
- Never place burning candles or similar open flames on the device/power supply!
Risk of Explosion!
Placing the device in unsuitable locations can cause explosions. Do not use the device:
- in fire- or explosion-prone environments!
- at extremely low or extremely high temperatures!
- near flammable gases or vapors!
- in areas with heavy dust!
- near easily flammable materials!
Risk of Electric Shock!
The power supply unit carries mains voltage internally, posing the risk of fatal electric shock.
- Never touch the power supply unit with wet hands!
- Use the device and power supply only in a dry location!
- Do not operate them outdoors or in damp areas!
- The device and power supply must be protected from all kinds of liquids, including dripping and splashing water.
- Do not place containers with liquids (e.g., flower vases) on or near the device or power supply!

- Ensure that no objects or foreign bodies enter the power supply unit through ventilation slots.
- If the device or power supply comes into contact with liquids or if objects enter the interior, unplug the power supply immediately and contact Nubert electronic GmbH!
Connection Instructions
General Connection Instructions
- Connect the power supply to the mains only after all other connections have been made!
- Use only the designated cables or connectors for the connections! Otherwise, damage or malfunctions may occur.
- If you want to disconnect connections on the device, always pull on the plug, never the cable!
- Ensure all plugs are securely seated in their sockets!
- Use only cables and accessories recommended by Nubert!

- Ensure that the mains voltage at your location matches the device's requirements! The correct power supply specifications can be found on the label of the power adapter. The device must not be connected to other power supplies.
- When routing cables, ensure they cannot be damaged (e.g., by heat or mechanical stress). Pay special attention to the areas around the plugs and connectors!
Caution!
Power surges in the mains (e.g., due to lightning strikes) can damage or destroy the device and power supply.
- A surge protection device can provide some level of protection against excessive voltage in the mains.
- However, the highest level of protection is achieved by completely disconnecting your devices from the mains and antenna systems. During thunderstorms or when lightning is likely, unplug the power supply and disconnect any antenna cables from your HiFi system!
