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 analogue audio as well as those
using digital AES/EBU audio. Genelec 7360A
and 7370A subwoofers are designed for
precise monitoring of multichannel analogue
audio signals and stereo AES/EBU signals.
Multichannel AES/EBU signal can be
monitored by using the 9301A 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 Genelec Loudspeaker
Manager (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 and an
operating manual. Before connecting switch
the subwoofer and monitors off.
Connections
Analogue input 1 thru 7
XLR balanced inputs, typically provided from
console or monitor controller. +24 dBu max.
Multichannel digital signal can be
monitored by using the 9301A AES/EBU
Multichannel Interface device connected to
the subwoofer.
LFE In
This is a dedicated input for LFE use with
analogue signals. Its bandwidth is extended
to 150 Hz. The addition of +10 dB is enabled
by the +10 dB DIP Switch.
Analogue Output 1 thru 7
Balanced XLR connectors for connecting the
main monitors to the subwoofer. Depending
on the chosen mode of bass management,
these outputs may carry either unfiltered or
high-pass filtered signal to the main monitors.
See chapter "Bass Management" for details.
LFE Out
Straight thru-put of the LFE In. Typically LFE
Out will be connected to LFE In when daisy-
chaining multiple subwoofers.
Link Out
Combined summation of main inputs 1 thru
7 that are passed along to a second or more
daisy-chained subwoofers. See chapter
"Using Multiple Subwoofers."
Link In
Use this input when daisy-chaining
subwoofers. Accepts ONLY the signal from
Link Out. Analogue inputs 1-7 should not be
used when Link In is connected. See chapter
"Using Multiple Subwoofers."
OUT1 / Test 1
Passes the 85 Hz Phase Test Tone when used
in the Stand Alone Manual Mode. Enabled
with the Dip Switch labeled "Test Tone".
OUT2/Test 2
Reserved for future use.
AES/EBU IN
Two channel AES/EBU digital input. This
input can also be configured to receive a
digital LFE channel using the GLM software
or the "Digital LFE" and "LFE Channel A/B"
switches.
AES/EBU OUT
Output is straight thru-put of AES/EBU IN.
BYPASS
Bass manager subwoofer Bypass. For use
with Stand-alone Manual mode. Accepts a
TRS/TS contact open/close device.
GLM NETWORK
Two CAT5 (RJ45) GLM Network connectors
for computer control using the Genelec
Loudspeaker Manager (GLM) software.
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
analogue main channels is default for manual
stand-alone use. However, we recommend
the use of the much more flexible distributed
bass management method.
In this method all analogue 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 network. This method is only
available in systems where GLM is used.
The GLM management 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.
