INTRODUCTION

Congratulations and thank-you for the purchase of this Genelec SE™ DSP Loudspeaker System. This

system is designed to integrate easily into the digital production environment. There are several ways to

conﬁgure and operate the SE™ systems for a wide variety of high quality audio applications.

This manual addresses the Genelec Loudspeaker Manager GLM.SE™ and the proprietary Genelec

loudspeaker control network, guiding step-by-step through the setup process. The SE7261A subwoofer

can also be used in stand-alone mode just like any other subwoofer, but without enjoying the beneﬁts of

additional ﬂexibility and versatility of the GLM.SE™.

SOFTWARE REGISTRATION

Please register your software at Genelec’s website www.genelec.com. The registration form is in the

Professional Monitoring/Products/DSP Monitoring Systems section. The user registration is essential to

Genelec as it allows keeping track of software versions as well as customer hardware revisions, allowing

us to serve you better.

This registration process requires the GLM software “Box Nr.” code. This code is physically printed on the

software package. Software updates cannot be obtained without complete, prior system registration.

GLOSSARY

.gse ﬁle GLM.SE™ System Setup File

.gtd ﬁle Genelec Time Data ﬁle containing the computed impulse responses of a

loudspeaker or subwoofer.

3.5 mm Measurement

Signal Cable

A 3.5 mm stereo jack-to-jack interconnection cable used to connect the

MIC OUT socket on the Network Interface to a computer’s soundcard

input.

AccuSmooth A proprietary smoothing algorithm that has a higher resolution (narrower

smoothing bandwidth) at low frequencies than a standard 1/3 octave

smoothing, and a similar resolution at high frequencies. This is used by

AutoCal™ to ensure accurate placement of notch ﬁlters at critical bass

frequencies.

Acoustical Settings Editor A page in the GLM.SE™ that provides access to the Acoustical Settings

in the loudspeaker or subwoofer. The Interactive Response Editor can

also be accessed here.

Acoustical Setup Wizard A self-guided Wizard that allows for manual or automated (AutoCal™)

calibration of the Loudspeaker Acoustic parameters.

Audio channel Although the deﬁnition of an audio channel is rather straightforward and

clear, it should not be confused with loudspeakers or audio cables in

the loudspeaker system. The AES/EBU digital audio cables may carry

one or two audio channels. There may be one or more loudspeakers

reproducing one audio channel.

Bass Management Bass Management is used to reproduce the low frequency content of

audio channels over one or more subwoofers instead of loudspeakers.

This can be the low frequency content from the full-bandwidth audio

channels. Parts or the entire LFE audio channel can also be bass

managed.

Digital Signal Cable The digital signal cable carries an AES/EBU audio signal.The GLM.SE™

supports AES/EBU digital audio cables typically carrying two channels

of audio.

Digital Thru The connector on the back of a loudspeaker used to pass the AES/EBU

digital audio signal presented to the digital input connector onto another

loudspeaker.

Genelec 8200A

Calibration Microphone

A factory calibrated acoustic measurement microphone used for

AutoCal™ system alignment.

Genelec AutoCal™ Genelec AutoCal™ is a property of the GLM.SE™ software that utilizes

built-in test signal generators inside the Genelec SE7261A Subwoofer to

acoustically measure and align the loudspeaker system.

Genelec AutoPhase Genelec AutoPhase is a part of Genelec AutoCal™. It aligns the phase of

the subwoofer in the system to the designated loudspeaker(s).

Genelec Sound Card Genelec Sound Card is a high quality sound card integrated in the

Network Interface device. It provides a precise frequency response

measurement with Genelec 8200A Calibration Microphone and Genelec

AutoCal™ function. The Sound Card is only active when AutoCal™

function is used.

GLM.SE™ Control

Network

The GLM.SE™ loudspeaker control network is a proprietary network

allowing the setting, reading and monitoring of loudspeakers and

subwoofers on the GLM.SE™ network. System setup can be achieved

very rapidly by simply opening a System Setup ﬁle, which causes all

system and loudspeaker settings to be automatically communicated to

all loudspeakers.

GLM.SE™ DSP

Loudspeaker Manager

Package

The GLM.SE™ control network delivery package containing all hardware

and software to build a GLM.SE™ Loudspeaker Manager environment.

8130As and SE7261As are purchased separately.

GLM.SE™ DSP Multiroom

Expansion Package

An expansion package providing a license and hardware to install the

GLM.SE™ in multiple rooms within a single facility.

GLM.SE™ Main Page The face of the GLM.SE™.This page is used to access all other functions

of Loudspeaker Manager.

Network Interface / Sound

card

The Network Interface is a USB device that connects the computer to

the GLM.SE™ loudspeaker control network. The Genelec Sound Card

is integrated in the Network Interface. The Network Interface translates

communication between the computer and the control network,

enabling a very large and physically long control network with multiple

loudspeakers. The Network Interface isolates the private and conﬁdential

messaging with loudspeakers from any public data networks and from

the functioning of the computer running the GLM.SE™ software.

GLM.SE™ System Setup

Editor

This page is used to access more detailed sections of the GLM.SE™

including the Acoustical Settings Editor.
