Genelec 7360A and 7370A Smart Active Subwoofers
Introduction
Congratulations and a thank-you for the
purchase of this Genelec 7300 series
subwoofer. This manual addresses setting
up and using the Genelec 7360A and 7370A
subwoofers. These subwoofers are designed
to integrate easily into all environments, both
those using analog audio as well as those
using digital AES/EBU audio. Genelec 7360A
and 7370A subwoofers are designed for
precise monitoring of multichannel analog
audio signals and stereo AES/EBU signals.
Multichannel AES/EBU signal can be
monitored by using the 9301 multichannel
digital audio interface device connected to
the subwoofer.
Energy saving Intelligent Signal Sensing
(ISS) can be turned on to put the subwoofer
automatically into a standby state when
audio signal has been absent for a selected
time. In the standby mode the product
consumes less than one Watt of power.
Upon sensing an input signal the subwoofer
automatically wakes up to full operation.
The wait until entering the ISS power save
can be configured using the GLM software.
When the ISS is active you can have your
monitoring system ready for action at all
times.
Installation
Each subwoofer is supplied with a mains
cable, one 5 m GLM network cable, mains
cable, and an operating manual. Before
connecting switch the subwoofer and
monitors off.
Connections
Seven balanced XLR input/output pairs
are available for analog signals (see Figure
1). There is a dedicated LFE In and LFE
Out. The Link In and Link Out connectors
can be used to for daisy-chaining multiple
subwoofers with minimum cable count. In
addition to these analog signal connectors,
digital audio in and out connectors
supporting AES/EBU format are available.
The digital out connector can be used to
daisy chain multiple subwoofers while digital
audio is being used.
Multichannel AES/EBU signal can be
monitored by using the 9301 multichannel
digital audio interface device connected to
the subwoofer.
Two CAT5 (RJ45) GLM Network
connectors are available for computer
control using the Genelec Loudspeaker
Manager (GLM) software.
Bypass connector supports a ¼ in
jack switch-operated subwoofer bass
management bypass function when the fixed
85 Hz subwoofer crossover is used.
The mains input supports a wide mains
voltage range (100-240 VAC, 50-60 Hz)
and enables the subwoofer to be plugged
in anywhere globally. If the mains power is
provided with a generator, inverter or certain
lower-quality UPS devices, we recommend
filtering of the mains power voltage
harmonics and taking care that the voltage
supply is stable.
Bass Management
Bass management splits the signal from
each input into low and high frequency
components. Signal content below the
crossover frequency is reproduced by the
subwoofer and signal content above the
crossover frequency is reproduced by the
monitors connected to the outputs of the
subwoofer.
The 7360A and 7370A offer two bass
management methods:
Centralized bass management
This method builds both the highpass and
the lowpass filters in the subwoofer and can
be used in all setups, with or without GLM
control. A fixed 85 Hz crossover filter for the
analog main channels is default for manual
use.
In this method all analog signal cables
are routed through the subwoofer's IN/
OUT connectors to the respective main
monitors.
Distributed bass management
In this method the lowpass filter is applied
in the subwoofer and the highpass filter in
the monitor, and these are set in synchrony
using the GLM control network. This method
is only available in systems where GLM is
used.
The GLM software enables adjusting the
subwoofer/monitor crossover from 50 Hz to
100 Hz when distributed bass management
is used.
The distributed bass management
supports three different signal cabling
configurations:
• All channels routed through the
subwoofer's IN/OUT connectors to the
respective monitors.
• Y-cables from the source to the
subwoofer's IN connector and the
monitor's signal input.
• Signal sources with dual outputs for each
channel.
Using With GLM™
Control Network
Subwoofers are fully compatible with
Genelec Loudspeaker Manager GLM™ and
the proprietary Genelec monitor control
network and Genelec SAM monitors. Using
the GLM control method unleashes the full
room compensation power in the subwoofer,
with 20 parametric room compensation
filters. This level of room compensation detail
is only available when the GLM is used. Use
with the GLM™ network is described in the
DSP System Operating Manual.
System setup
Although the subwoofer can be used without
the GLM™ software and control network,
they only reach their full potential when
set up and calibrated using the GLM™
software. Genelec Loudspeaker Manager
GLM™ and the proprietary Genelec
monitor control network offer automated
acoustic equalization and alignment for any
reproduction system from simple stereo to
very complex 3D immersive setups including
also one or more subwoofers. GLM setup is
fast and accurate and can precisely address
the typical narrow-band low frequency mode
resonances of a room. The settings can be
controlled with a computer or be permanently
stored in the monitors to make the setup
available at all times even when a computer
is not in use. Genelec recommends setting
up SAM monitoring systems using GLM. You
can find a detailed description of the setup
and the use of GLM™ in the GLM™ System
Operating Manual.
