AES/EBU Out
The AES/EBU Out is a bit-to-bit copy of
the digital audio signal on the AES/EBU IN.
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.
This can create a 2.1 digital audio stereo
monitoring system.
Bypass
The Bypass input accepts a 6.3 mm tip-ring-
sleeve (TRS) or tip-sleeve (TS) plug. This
plug supports a contact open/close switch
device. Connecting the TIP to the SLEEVE
activates the bass management bypass.
When the bass management bypass is
active, the subwoofer only reproduces the
LFE signal and the outputs bypassed to the
monitors are exact copies of the inputs.
The Bypass switch is intended to be used
when the subwoofer is set up using the
controls built in the subwoofer.
The GLM software control enables also
bypassing the bass management and offers
a wider set of controls and adjustments.
When the GLM is used, the TRS bypass
control is not needed.
GLM Management Network
All controls and calibration features included
in the 7380A SAM subwoofer can be set using
the Genelec Loudspeaker Manager (GLM)
software. Two GLM Network connectors are
provided on the subwoofer for computer
control. These connectors 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.

Mains Power Input
The main power connection supports a
wide mains voltage range (100-240 VAC,
50-60 Hz). This enables the 7380A SAM
subwoofer 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.
