System Description

The Genelec 7382A SAM subwoofer is designed for professional use and integrates easily into environments based on analog or digital interfacing. The 7382A even introduces outstanding GLM™ features to the lower octaves of monitoring systems based on main speakers from a different vendor.

Multichannel AES/ EBU signals can be monitored by using the 9301A multichannel digital audio interface device connected to the subwoofer.

The 7382A is intended to be calibrated to the monitoring room acoustics using the Genelec Loudspeaker Manager (GLM) computer software. The GLM software runs on Mac OS and Windows computers and enables detailed acoustic calibration permanently inside the subwoofer. It is also possible to use the GLM software as a monitoring management system for more than 30 SAM monitors and subwoofers.

In its power save mode, the 7382A consumes less than 1 W of power. Energy saving Intelligent Signal Sensing (ISS) can automatically put the subwoofer into a power save mode when audio has been absent for a selected time. Upon sensing an input signal, the subwoofer wakes up to full operation. The time before entering the ISS power save mode can be configured using the GLM software.

Package content

Each subwoofer is supplied with an individually calibrated RAM-SW amplifier unit. If several 7382A subwoofers are used in the same system, it is very important not to mix the subwoofer/amplifier pairs. A mains cable, a 10 m (33.3 ft) Speakon signal cable, one 5 m GLM network cable and this operating manual are also included.

Operating Environment

This subwoofer is designed for indoor use only. The permissible ambient temperature is 15-35 degrees Celsius (50-95°F) and relative humidity 20 - 80% (noncondensing). When the product has been stored or transported in a cool environment and is taken into a warm room, wait about one hour before opening packing to prevent condensation of humidity before connecting to mains power.

Genelec Loudspeaker Manager™ (GLM™) Software And GLM User Kit

The GLM software gets the most out of 7382A and tailor-fits it to your room. GLM is available for download free of charge at www.genelec.com/glm. Check in from time to time to take advantage of new features, or consider using the cloud-based version.

A GLM User Kit comprising the necessary hardware, including the GLM Adapter and measuring microphone is needed for building and operating the GLM network. This kit can be purchased at certified Genelec dealers.

Connections

Before connecting signal cables, switch the subwoofer amplifier and monitors off.

Analog Inputs 1 and 2

The 7382A SAM subwoofer accepts balanced XLR inputs. These are the outputs typically provided in a console or a monitor controller. The maximum balanced audio signal level is +24 dBu.

LFE In

A dedicated XLR input is provided for the analog LFE signal. The bandwidth for a signal fed to the LFE input is 120 Hz. The LFE input sensitivity can be set the same as for the main channels or at +10 dB relative to the main channels. This feature is set in the GLM software.

IN Digital

One AES/EBU digital audio XLR input is available on the 7382A subwoofer. This can take a stereo digital audio signal.

Multichannel digital audio monitoring is possible with the 9301A interface device. The 9301A connects to the digital audio input in the 7382A subwoofer and expands the number of digital audio inputs to four XLR digital audio inputs. This supports a 7.1 audio system, including an LFE channel.

Analog Output 1 and 2

Analog balanced XLR connectors connect the subwoofer to the monitors.

These analog outputs carry an unfiltered copy of the inputs. The subwoofer/main monitor crossover is adjusted in the GLM software from 50 Hz to 100 Hz.

See chapter "Bass Management" for details.

THRU AES/EBU

The THRU AES/EBU is a bit-to-bit copy of the digital audio signal on the IN Digital. This output can be used for digital sharing of the audio between subwoofers in the case where multiple subwoofers are used. This output can also be used for distributing a stereo digital audio signal to monitors, creating a 2.1 digital audio stereo monitoring system.

Subwoofer Connector

This Speakon connector is used for linking the RAM-SW amplifier unit and the 7382A subwoofer enclosure. There is a corresponding connector on the reflex port end of the enclosure.

A 10 m (33.3 ft) cable is provided with the subwoofer. See Table 1 for recommended minimum gauges for different lengths of

GLM Management Network

All controls and calibration features included in the 7382A SAM subwoofer are set using the Genelec Loudspeaker Manager (GLM) software. Two GLM Network connectors are provided on the amplifier for computer control. These accept CAT5 or higher cable (RJ45 connector). Standard CAT cables can be used.

The GLM management network runs a proprietary protocol. This is not an Ethernet connection, do not connect to an Ethernet network.

LED Connector

This connector allows linking a remote status indicating light if the amplifier unit is placed so that its front panel light can not be seen.

Mains Power Input

The main power connection supports a wide mains voltage range (100-240 VAC, 50-60 Hz). This enables the RAM-SW amplifier to be plugged in anywhere globally. When the mains power is provided with a generator, inverter, or certain lower-quality UPS devices, we recommend filtering power to remove harmonics and ensuring the voltage supply is stable.

Bass Management

Bass management divides the input audio signal into low frequency and high frequency content at the subwoofer crossover frequency. The signal content below the crossover frequency is reproduced by the subwoofer. The signal content above the crossover frequency is reproduced by the monitors.

In the distributed bass management method used in the 7382A system, the monitors and the subwoofer receive full bandwidth audio signal and the filtering is done separately inside each monitor and subwoofer. The lowpass and highpass filters are set in synchrony by the GLM management network. This method is only available in systems where GLM computer management is used and with monitors supporting this method. The subwoofer crossover frequency can be adjusted from 50 Hz to 100 Hz.

The distributed bass management supports three different signal cabling configurations:

• All channels are routed through the subwoofer's IN/OUT connectors to the respective monitors.
• Y-cables split each signal to the subwoofer's IN connector and the monitor's input.
• Signal sources with dual outputs for each channel, one going to the subwoofer, the other going to the monitor.

Use With GLM Control Network

The 7382A SAM subwoofer is fully compatible with Genelec Loudspeaker Manager GLM software, the proprietary Genelec monitor management network, and all Genelec SAM monitors.

Managing the 7382A SAM subwoofer using GLM software control unleashes the full power of room compensation in the 7382A SAM subwoofer, enabling 20 parametric room compensation filters. This powerful room compensation functionality is only available when the GLM is used. Detailed information on the use with the GLM network is presented in the GLM System Operating Manual.

System Setup

The 7382A SAM subwoofer reaches its full potential when set up and calibrated using the GLM software. Genelec Loudspeaker Manager GLM and the proprietary Genelec monitor management network offer

• automated acoustic equalization individually for every monitor and subwoofer
• automated level alignment
  • distance (acoustic time-of-flight) calibration
• aligning of the subwoofers for bass management

for any reproduction system from stereo to complex 3D immersive setups, including one or more subwoofers. GLM setup is fast and accurate. It can precisely address the typical narrow-band low frequency modal resonances and radiation loads of a room and offers precise frequency response compensations. The settings can be controlled with a computer or the settings can be permanently stored in the monitors and subwoofers, to make the setup available at all times even when the computer is not in use. Genelec recommends setting up SAM monitoring systems using the GLM. You can find a detailed description of the setup process and the use of GLM in the GLM System Operating Manual.

The setup using GLM is fast and consists of the following steps:

- Connect a CAT5 (RJ45) cable between each monitor (and subwoofer) and finally to the control network input of the GLM Adapter device (see Figure 1).

- Connect the GLM Adapter device to computer USB connector.

- Using a microphone stand, place the Genelec measurement microphone at the listening location with the microphone pointing upwards and the microphone top at the height of the engineer's ear. The microphone is a part of the GLM User Kit.

- Connect the GLM Adapter device to the computer USB port using cable included in the GLM User Kit.

- Download the GLM software at the Genelec web site (www.genelec.com).

• Install the GLM software and follow the instructions in the software to measure and set up your system.

- If you plan to not use a computer for controlling the subwoofer, use the GLM software to write the setting into the subwoofer (use menu item "Store | Store the Current Group Settings...").

With GLM software active and controlling the 7382A SAM subwoofer, the use of analog

and digital inputs is controlled by the GLM software entirely. In the software 'Input Type' in the 'Group' definition sets this. The GLM software allows you to select and switch between the analog and digital audio inputs.

If GLM control is not used, an AES/EBU digital audio signal will override analog signal. This means, if a valid digital audio clock is detected, the digital audio is selected over the analog audio.

When the GLM acoustic settings have been stored in the 7382A SAM subwoofer and are active, the input is selected by the 'Group' settings in the GLM software when the settings are stored.

RAM-SW Power Switch Light

When used without a connection to the GLM software, the light on the power switch on the RAM-SW is green, indicating normal operational mode. A red colour indicates amplifier clipping and yellow indicates thermal overload. If the red or yellow warning light appears, turn down the level.

Additional Information

Positioning the Subwoofer in a Room

The location of the subwoofer can affect the frequency response and sound level dramatically particularly when the room acoustic effects are strong. Even small changes in a subwoofer's location can make a marked difference in the frequency response. To begin, place the subwoofer near the front wall slightly offset from the room center line. Often systematic experimentation is needed to find the location giving the flattest frequency response at the listening location. Usually the subwoofer is placed close to a wall as this creates the highest output. Positioning the subwoofer close to a corner will boost the bass level at lower frequencies and may also cause asymmetrical spatial imaging. Measured from the subwoofer's driver the recommended distance to a wall is less than 0.6 m (24 in). This avoids a loss of audio level at low frequencies created by the audio reflecting off the wall and cancelling certain frequencies radiated by the subwoofer.

Operating Environment

This subwoofer is designed for indoor use only. The permissible ambient temperature is 15-35 degrees Celsius (50-95°F) and relative humidity 20 - 80% (non-condensing). When the product has been stored or transported in a cool environment and is taken into a warm room, wait about

one hour before opening packing to prevent condensation of humidity before connecting to mains power.

Minimum Clearances

Do not cover the amplifier or place it in a closed cabinet. The space must be ventilated or sufficiently large to dissipate heat so that the ambient temperature does not rise above 35 degrees Celsius (95°F). The reflex port opening on the enclosure should have a clearance of at least 20 cm (8 in) to ensure functioning of the reflex port.

Flush Mounting

When the subwoofer is flush mounted in a wall or cabinet, ensure unrestricted airflow in the reflex port and amplifier cooling. Make the recess 20 cm (8 in) wider than the subwoofer. Place the subwoofer to the right side of the recess if the driver is facing the room. This leaves sufficient free space at the reflex port side. The height and depth of the recess should not be much bigger than what is needed as this may cause unwanted acoustic effects.

Using Multiple Subwoofers

Multiple Genelec 7382A subwoofers can be coupled together in high SPL applications. The necessary cabling is different for digital and analog signals. When subwoofers are close to each other, the sound level increases typically by 6 dB for each doubling of the number of subwoofers. When subwoofers are far from each other, the total increase in the sound level can be less. It is safe to assume the increase is 3 dB for each doubling of the number of subwoofers. Accurate understanding of the increase in sound level requires acoustic measurements.

Digital Cabling

Run a signal cable from the THRU AES/EBU connector of the first subwoofer in the chain to the IN Digital connector of the next subwoofer.

Analog Cabling

When daisy-chaining multiple subwoofers with analog signals, run cables from the OUT 1 and 2 connectors to the next subwoofer's IN 1 and 2 connectors. The LFE channel has
