Genelec 8381A - System Calibration and Software; GLM Software and Calibration Process

You may also build your own
interconnecting cable assembly. For this,
connect the eight-pin 'Speakon' connectors
pin-to-pin using at least the cable gauge
given in Table 1. The cable gauge depends
on the length of the cable. Pin-to-pin
connection means that pin number 1 in the
rst Speakon connector is connected to pin
number 1 in the second Speakon connector,
and so on.
As the RAM-81 ampliers can produce
potentially hazardous voltages, use a
trained electrical technician to build and
connect the custom Speakon cables to
ensure safety and compliance with local
regulations.
Standard CAT 5 or CAT 6 cables can
be used for the RJ-45 interconnection
between the ampliers and the enclosure,
and dierent lengths are available in stores
selling CAT cables. Do not use special CAT
cables with crossed interconnections or
cables that do not have all pins connected.
RAM-81 LINK Amplifier Communication
Cable
The two ampliers communicate using one
interconnecting control network cable. This
link interface is named 'RAM-81 LINK'. This
cable is provided.
The GLM network cable is connected to
Amplier Unit 1 and, if needed, continued
to further Genelec SAM monitors using the
GLM output on Amplier Unit 2. See Figure
6.
Audio Cabling
The incoming audio signal(s) are connected
to Amplifier Unit 1. The THRU out is
connected to the input of Amplier Unit 2.
XLR male-to-female cables are provided for
this. See Figure 9.
System Calibration
GLM software can fully set up your Genelec
Smart Active (SAM) Monitoring system.
GLM software works with SAM monitors to
minimise the unwanted acoustic inuences
of the monitoring room and helps your mixes
sound great, everywhere. Among other new
features, GLM system calibration includes
the optional GRADE Report, extending
GLM's scope beyond ultra-precise system
calibration, to complete in-depth room and
system acoustical analysis.
Connecting GLM Network
In order to use the setup software, the GLM
Network must be connected (see Figure 6):
• Link Amplier 1 and Amplier 2 using the
supplied CAT5 (RJ45) cable. Connect
the cable between the RAM-81 LINK
connectors on both ampliers.
• Link all monitors and subwoofers in
a daisy-chain manner by connecting
CAT5 (RJ45) cables to the 'CONTROL
NETWORK' connectors of all the
Genelec SAM monitors and RAM
ampliers. The order connection in the
daisy-chain is not important.
• Run the nal network cable to GLM
network input in the GLM Adapter
device.
• Connect the GLM Adapter device to the
USB connector on your computer.
Measurement Microphone Placement
Place the Genelec measurement microphone
on a stand at the listening location of the
engineer, with the microphone pointing
upwards and the microphone top at the
height of the engineer’s ear at the position
where the engineer would normally work.
The microphone is a part of the GLM User
Kit. Run the microphone cable into the
microphone input of the GLM Adapter
device.
In case of a multi-point calibration, several
microphone positions are used. Consult
the GLM Operating Manual for further
instructions.
Installing and Using GLM Software
Download GLM software at the Genelec
web site (www.genelec.com). Install the
GLM software. The software comes with an
operating manual explaining the process of
calibrating the monitoring system. Follow
the GLM software instructions to measure
and set up your monitors. You can choose
to calibrate for one listening position or
for a wider listening area, using multiple
measurement microphone positions.
GLM software can calibrate any SAM
monitoring system up to tens of monitors
