Frequently Asked Questions - 7350A GENELEC

What is the bass management architecture of the Genelec 7350A?

The 7350A features Distributed Bass Management (DBM), where filtering is shared between the subwoofer and the monitors. The subwoofer applies a low-pass filter to its output, while each monitor applies a high-pass filter independently.

Can the 7350A be used with legacy Genelec monitors like the 8240?

Yes, but with configuration changes. When using legacy monitors (N-DBM) with a 7350A, you need to set the subwoofer's crossover to 'Individual' and enable Pass Through Mode to ensure proper high-pass filtering by the subwoofer.

What is the difference between Centralized and Distributed Bass Management?

In Centralized Bass Management (CBM), all filtering is done in the subwoofer, which outputs high-passed signals to the monitors. In Distributed Bass Management (DBM), the subwoofer outputs a full-range signal, and each monitor applies its own high-pass filter. The 7350A uses DBM.

How do I connect digital audio to the 7350A?

Connect an AES/EBU digital source to the subwoofer input. The 7350A can pass the digital signal through its outputs to other devices when Pass Through Mode is enabled. See the user guide for specific wiring diagrams.

What crossover settings are available on the 7350A?

Using the GLM software, you can set the crossover frequency (default 85 Hz) and choose between Individual or Global mode. Global applies the same crossover to all connected monitors, while Individual allows per-device settings.

Can I use the 7350A in a standalone analog system without GLM?

Yes, the 7350A can operate in analog mode with basic settings. However, full configuration and bass management optimization require the GLM 2.0 software and a network connection.

What is the purpose of the LFE channel input?

The LFE (Low Frequency Effects) channel is input 4 on the 7350A. It allows connection of a dedicated LFE signal (e.g., from a surround decoder) with selectable gain of 0 dB or +10 dB for accurate reproduction.

How do I set up the 7350A with DBM monitors like the 8330?

In a DBM setup, connect audio signals first to the subwoofer (or in parallel). No additional changes are needed in the subwoofer panel; each monitor will apply its own high-pass filter. Ensure the crossover setting is set to Global for consistent frequency.

What should I do if the subwoofer output seems low or distorted?

Check the input signal level and ensure the crossover settings are correct. Verify that the LFE channel gain is set appropriately. Also, confirm that Pass Through Mode is not accidentally enabled if not needed. For persistent issues, run the GLM calibration.

Is the 7350A compatible with the Genelec 7270 subwoofer?

The 7350A and 7270 are different models; they cannot be chained in a standard setup. Each has its own bass management architecture. You can use multiple subwoofers in a system, but they must be configured individually via GLM for proper integration.

Genelec Bass Management User Guide

Centralized & Distributed Architectures

The purpose of this Application Note is to provide further insights into centralized and distributed bass management architectures as well as to provide a practical user guide about the inter-compatibility between various Genelec Smart Active Monitor (SAM) systems.

The terminology used in this document is as follows:

• Legacy monitors featuring Non-Distributed Bass Management (N-DBM) include the following SAM products: 8240, 8250, 8260, 1238CF.
• Legacy subwoofers include the following SAM products: 7260, 7270, 7271. They feature Centralized Bass Management (CBM), meaning the subwoofer defaults to High Pass filtering its outputs. Legacy subwoofers have the additional possibility to be set to a “Pass-Through Mode” while the Low Pass crossover is engaged. This function is most often used when linking multiple subwoofers together, but is also important when subwoofers are combined with DBM monitors.
• Latest monitors and subwoofers featuring Distributed Bass Management (DBM) include the following SAM products.
  Monitors: 8320, 8330, 8340, 8350, 8351, 1237, 1238, 1238AC, 1238DF, 1234, 1236. Subwoofers: 7350, 7360, 7370.

A. The principle of Bass Management

The term Bass management means that full bandwidth audio channels are low-pass filtered and combined in order to be reproduced by one or more subwoofers. Additionally in the multichannel audio realm, an additional LFE (low frequency effects) channel can also be combined with the low frequency content.

A Bass Management system uses either analogue electronic circuitry or software-based DSP filtering which will filter low frequency information from the main channels and route that information to one, or more, subwoofer feed.

The outputs of the bass management system are directed to two directions: the subwoofer as mentioned above and the main monitors.

Bass management provides several benefits:

• The subwoofer extends the system frequency response down to the lower limit of the audible range
• The monitors can produce a higher maximum sound level when not reproducing low frequencies
• It is possible to optimize the low frequency reproduction by selecting an adequate subwoofer location in the room
• The monitors can be placed with more freedom to control the acoustical environment and to improve the quality of the audio reproduction
• The subwoofer's output is aligned in level and phase with the monitors allowing flat and accurate reproduction down to 19 Hz and across the crossover point
• The LFE channel output level (0 or +10 dB re. main channels) can be selected for accurate reproduction depending on the final encoded audio format
• The ability to bypass the subwoofer allows evaluation of the audible impact of the subwoofer

B. Centralized Bass Management Architecture (CBM)

The so-called centralized bass management architecture places all audio signal filtering resources in one central location, the subwoofer bass management unit. This means that all bass-managed subwoofer outputs provide filtered audio signals:

• A low-pass-filtered signal output to the subwoofer driver
• A number of high-pass-filtered outputs for each individual monitor(s)

    style H fill:#00BFFF,stroke:#333

One consequence of using the centralized bass management architecture is that it is mandatory that all audio signal cabling must first go to the subwoofer containing the bass management unit. Then, each respective audio signal cable will go to each relevant monitor input.

C. Distributed Bass Management Architecture (DBM)

The so-called distributed bass management architecture shares the audio signal filtering resources between the filtering occurring in the subwoofer bass management unit and the filtering occurring in each individual monitor. This means that each monitor and subwoofer filter locally and individually the necessary signal using, of course, the same nominal crossover frequency.

• The subwoofer filter provides only a low-pass-filtered signal output for the subwoofer driver
• The output from the subwoofer is not modified, but is an exact copy of the input signal and this applies to both the analog and AES/EBU inputs
  • Each monitor applies a high-pass filter to its input signal

The distributed bass management architecture allows the audio signal cabling to go:

a) First to the subwoofer and then feed all output signals to the respective monitor(s) – (Genelec default cabling scheme recommendation).

b) In parallel via a split cable to feed both the subwoofer and each appropriate monitor.

E. SAM Subwoofer – System Settings User Guide

The combination of Legacy monitors (N-DBM), Legacy subwoofers and Latest monitors and subwoofers (DBM) present some challenges in connectivity, cabling and GLM 2.0 software system settings.

The following user guide aims to provide a simple checklist chart covering all possible combinations and scenarios. The terminology used in the table below is:

Crossover setting (individual or global):

Forces the same crossover frequency setting in all monitors and subwoofers (setting 'global'). When 'global' is selected and the subwoofer bass management settings are changed, all monitors with 'global' selected will follow the changes. When 'individual' is selected in a subwoofer or monitor, it will not follow changes made to the subwoofer bass management settings at any other part of the system.

Pass Through Mode:

The 'Pass Through Mode' setting defaults to OFF. You can force the subwoofer AES/EBU outputs to 'Pass Through Mode' ON. This sends a bit accurate AES/EBU copy to all outputs.

Subwoofer / Monitor Combination	What to do in the Subwoofer Edit Panel	What to do in the Legacy Monitor (N-DBM) Edit Panel	What to do in the Latest Monitor (DBM) Edit Panel
Latest Monitors (DBM): Compact SAM (7350, 8320, 8330)	Nothing. (Subwoofer Crossover is defaulted to Global).	N/A.	Nothing.
Legacy Subwoofer with any Latest monitors (DBM)	Subwoofer Crossover is defaulted to Global.Pass Through Mode button should be set to ON.	N/A.	Nothing.
Legacy Subwoofer together with Legacy Monitors (N-DBM) and Latest Monitors (DBM).Example: 7270 with 1237s (LCR) and 8240/8250 (RL/RR)	First set Subwoofer Crossover from Global to Individual.Pass Through Mode set to OFF (default).	Nothing. (High pass is provided by the subwoofer).	Set each Latest Monitor (DBM) Crossover to "Full Band".The meaning "Full band" indicates there is no DBM filter activated and that the Latest monitor is ready to accept a Legacy Sub High-pass signal.
Special Case:Legacy Subwoofer together with Legacy Monitors (N-DBM) and 8330s (DBM).Example: 7260 with 8240s (LCR) and 8330s (RL/RR).	Leave Subwoofer Crossover defaulted to Global.Pass Through Mode set to OFF (default).	Nothing. (High pass is provided by the subwoofer).	When 8330s are used with Legacy Subwoofers, you must wire digital audio signals first to the 8330s and then loop their outputs to the Legacy Sub.
