2 UNIO Concept
Genelec UNIO concept unifies the loudspeaker-based and headphone-based methods of monitoring to
one reliable and precise workflow, enabling secure bridging from using loudspeaker-based monitoring to
using headphone-based monitoring.
This manual describes the set-up, configuration, and use of the 9320 device while the GLM User
Manual and Aural ID Operating Manual discuss the configuration of the loudspeaker- and headphone-
based monitoring. Please consult all three manuals as you configure your UNIO system solution.
2.1 Genelec Loudspeaker Manager Software
In the area of loudspeaker-based monitoring, the Genelec Loudspeaker Manager (GLM) software with
its integral AutoCal automatic system calibration and alignment function, creates an easy step to
enhance the precision and accuracy of monitoring, by reducing any uncertainties related to the room
acoustic and loudspeaker installation locations and distances.
2.2 Smart Active Monitor Systems
Genelec Smart Active Loudspeaker (SAM) systems provide a wide selection of output capacity levels,
suiting for all room sizes and applications, to implement loudspeaker-based monitoring layouts. With
GLM software, precise calibration and bass management alignment is automatic and fast.
Understanding the system performance is supported by the extensive GRADE report on room acoustic
performance presenting complete information of the uncalibrated and calibrated system performance.
2.3 Reference Controller
The 9320 is a key device in the UNIO concept thinking, unifying the use of both the loudspeaker based
and headphone based monitoring technologies and enabling equal access to loudspeaker-based and
headphone-based monitoring. 9320 integrated completely with GLM software and Aural ID software, to
empower fully integrated and efficient monitoring setups for all applications.
2.4 Aural ID Technology Integration
In the area of headphone-based monitoring, the Genelec Aural ID technology enables you to access
your personal way of directional hearing in the form of your own Head-Related Transfer Function
(HRTF) and the use of this in the Aural ID Plug-In and Aural ID Stand-Alone processing methods,
including head tracking to maintain the layout of virtual monitoring loudspeakers on your headphones to
remain stationary in space as you move and rotate your head wearing the headphones. The Aural ID
technology provides a reliable and precise methodology to personally calibrate the virtual audio
monitoring setup for your specific headphones and your HRTF information, enabling headphone
monitoring able to access details similar to those available in loudspeaker-based monitoring.

 Detailed GRADE acoustic analysis report on SAM monitoring systems (when using GLM
software)
 Access to Genelec Aural ID technology to enable personal HRTF rendering for reliable
immersive monitoring (when using Aural ID 2.0 or later)
4.1 Reference Controller Signal Processing
The system frequency response of 9320 extends from 0.2 Hz (-3 dB) and up to 45 kHz (-3 dB) on all
outputs for complete delivery of the full recorded audio content. The AES digital audio input accepts a
samples rate range 32–192 kHz and word lengths up to 24 bits. The highest USB audio interface sample
rate is 192 kHz.

9320 Reference Controller Operating Manual 10 (52)
The possible signal flows in 9320 enable any audio input to be routed to any audio output. This enables
very versatile patching of signals for monitoring using 9320A, and fluent mixing of analogue and digital
audio pathways in demanding monitoring applications.
9320 supports seamless blending of loudspeaker-based monitoring with headphone-based monitoring,
and integration of personal HRTF processing using Genelec Aural ID technology. 9320 integrates
completely with Genelec GLM software for calibrating and managing Genelec SAM monitoring
loudspeakers. There is complete support for all professional analogue and digital audio monitoring
loudspeakers and headphones.
The maximum signal into the analogue line input can be set such that the total system dynamic range is
optimized. There are two selections, for maximum input levels of +12 dBu (HiGain) and +24 dBu
(LoGain). This feature is configured using the GLM software, as a part of all other 9320 configurations.
In the signal processing diagram the volume control is presented before the signal processing functions
for sake of clarity. In reality, to maximize the dynamic range of the audio signal, volume control happens
as the last signal processing function before the signal is output.
Fig. 1. Signal processing block diagram of 9320A.
4.2 Intended Ways of Using
9320 is intended to be used with the GLM software and Aural ID software but can be also used in the
Independent mode.
4.2.1 Loudspeaker-Based Monitoring
9320 Reference Controller is a physical user interface for the most important Genelec Loudspeaker
Manager (GLM™) functions, empowering management of Genelec Smart Monitoring System (SAM™)
from stereo to immersive and enabling easy management of alternative monitoring systems.
9320 offers direct connectivity to analogue and digital stereo or 2.1 monitoring of audio signals input
using the USB soundcard function, analogue line input or AES digital audio input. The outputs can be
level aligned for smooth switching across inputs and outputs. Genelec SAM monitoring systems can be
automatically calibrated using the GLM AutoCal™ calibration and the included measurement
microphone. This gives access also to the detailed GRADE acoustic analysis report on SAM monitoring

9320 Reference Controller Operating Manual 11 (52)
systems. Using the measurement microphone, continuous sound level monitoring is available with the
SPL display, noise dose logging and hearing health alarms linked to the noise dose.
9320 Reference Controller supports compensation of the monitoring system output sensitivity, enabling
smooth switching between all connected monitoring systems as well as switching to Genelec SAM
monitoring systems controlled by 9320A.
4.2.2 Headphone Monitoring
In addition to the loudspeaker-based monitoring solutions, the 9320 offers a professional-grade
headphone monitoring output, support for personal headphone sound character calibration and access
to Genelec Aural ID technology enabling rendering of audio using a personal HRTF for reliable stereo
and immersive channel layout monitoring with accuracy similar to using loudspeakers.
The headphone output is usually described using the headphone sensitivity or the headphone efficiency.
The headphone sensitivity explains how high sound level is created with a known magnitude of
electronic input, given as dB SPL per input voltage. The headphone efficiency is given as the sound
level (dB SPL) generated with a given input electrical power. One of these figures is usually stated in the
data sheet of a headphone and can be used to understand the maximum sound level a headphone can
reach with 9320 headphone amplifier.
The headphone amplifier in 9320 supports professional headphones in the impedance range 16–600
ohm. The maximum output current to the headphone is 120 mA, and the maximum output voltage is 6
Vrms. The maximum output power to the headphone depends on the headphone impedance (see Table
1). At higher headphone impedances the maximum output power will reduce.

selection keys on the right side, control knob and display.
Fig. 3. Elements in the 9320 controller user interface.
Fig. 4. The 9320 controller user interface.
5.1.1 Powering Up and Down
The 9320 is powered up and down by pressing the MENU key.
To power the 9320 down, a long press on the MENU key is needed. When power down time-out count
begins, the display shows the waiting time passing until 9320 powers down.
Fig. 5. The power-down counter display in 9320A.

9320 Reference Controller Operating Manual 14 (52)
If the MENU key is released before the power-down counter reaches zero, 9320 resumes normal
operation. The power-down counter is shown to prevent unwanted or accidental powering down of
9320A. The 9320 can also be turned off by selecting the ‘Power Down’ in the MENU.
5.1.2 Control Knob and Display
The control knob with two main functions: volume control and volume control in GLM and selection and
adjustment when using menu functions. The knob controls output level to the selected output and the
GLM Smart Active System volume level. When the absolute SPL display is set in the GLM software, the
volume value is shown as sound level at the listening position, in dB SPL scale. The display shows the
current output level on SPL scale relative to the max SPL, or on absolute SPL at the listening location,
available after calibration. The top row can contain small labels and these indicate the state of the 9320.

When the “Max level” label is shown, the maximum SPL restriction has been set and is
active

9320 Reference Controller Operating Manual 15 (52)
5.1.3 Physical Control Mapping to GLM
The 9320 controls match the controls in the GLM software user interface and local controls. Using 9320
can replace the use of GLM software, enabling GLM to run in the background in a digital audio
workstation while having physical controls to access most essential GLM functions.
Fig. 7. The matching controls in the 9320 (left) GLM software (right).
GROUP keys are an effective and fast way of switching between Groups in the GLM software setup. A
Group contains all the setup-related settings for the GLM and the SAM monitors that affect the room
equalization, system alignment, level preset calibrations, and audio input selections, and are therefore a
very efficient means of moving between different monitoring situations. The four GROUP keys located at
the right side activate the first four Groups set up in the GLM software user interface. If less than four
Groups have been set up in the GLM software, only the GROUP keys matching with actually existing
Groups in GLM will select a group. For more information on how to set up and use Groups, please
consult the GLM User Manual.
The GROUP key texts light up (white) when a group is defined in GLM software. If one or more of the
four groups is not defined, the key text remains dark.
Fig. 8. The four GROUP keys select and activate (left) the first four Group settings in the GLM software
user interface (right).
The GLM user interface software has a powerful set of system level management selections. In addition
to controlling mute and dim functions, these can also offer access to calibrated monitoring level. The
MUTE, DIM, PRESET and BASS M physical keys on 9320 are directly controlling the ‘Mute All’, ‘Dim
All’, the first system preset level and ‘Bass Man’ settings in the GLM software user interface. In this way,
9320 offers a quick way of managing the complete monitoring playback.

9320 Reference Controller Operating Manual 16 (52)
The preset level is configure in GLM software, and the value is stored in the System Setup File.
The BASS M switch operates the bass management bypass system in GLM software. Bass
management bypass prevents crossover filtering in a subwoofer and passes the full band signal to
monitors instead of filtering and playing the low frequencies in the subwoofer.
The mute, dim, preset and bass management functions can be configured using the GLM software.
Fig. 9. The MUTE, DIM, PRESET and BASS M keys control the ‘Mute All’, ‘Dim All’, system preset level
no 1 (top key) and ‘Bass Man’ keys in the GLM user interface software.
5.2 Menu Functions
Entry into the menu functions is done by pressing the MENU key. This brings the menu selection into the
main display. A menu function can be selected by rotating the control knob. To adjust first rotate the
knob for the right function, then enter the function by pressing the MENU key.
Fig. 10. Menu-related controls in 9320A.
Each function can contain several items. The items can be selected by rotating the control knob and
then pressing MENU key to select an item. Once inside the item, the setting or value of the item can be
seen; to adjust the values, use the GLM software.
At any time, it is possible to cancel the current menu selection or to back up to the top of the menu tree
using the MONO key that also shows the reverse arrow icon.

The mode of level control is shown after the output name as “9320 level control” when the 9320
Reference Controller is adjusting the level of the outgoing audio signal level when the volume level is
being adjusted.

9320 Reference Controller Operating Manual 20 (52)
Fig. 15. The output level adjusted by 9320A
Pressing any output key longer than 3 sec turns all outputs in 9320 off. Then, the display shows the text
“No output” and the second line “GLM level control”. After a brief time, the display returns to the main
display, showing the current level setting but all the outputs in 9320 remain off. This mode can be useful
for example 9320 is adjusting level on a set of SAM monitors particularly when the GLM software is not
in ise, and the 9320 works in stand-alone mode. This mode is indicated with the second line of text in
display saying “GLM level control”.
Pressing any output selection key when the “GLM level control” mode is active returns the outputs in
9320 on.
Fig. 16. The output of 9320 not in use, for example when 9320 is controlling an external set of SAM
monitors receiving audio from an outboard audio interface.
The MUTE key mutes all outputs of 9320A, and outputs controlled by the GLM software, making the
MUTE key a universal way of muting all audio controlled by 9320A.
5.5 Display Screen Saver and key LED brightness
When any control (knob, keys) on the 9320 is used, the display in 9320 automatically turns on. The 9320
detects the brightness in the room and adjust the brighness of the display and the key lighting
automatically with the room illumination.
The display automatically screen saver turns the display off after a period of no access to the 9320
physical controls. The display screen saver activates in steps. If ot controls on the 9320 are used, the
display brightess reduces first, and after some time, the display turns off.
This display screen saver is always active and cannot be disabled, but the screen saver activation time
can be adjusted. The screen saver activation time can be adjusted using GLM software, in the 9320
setup, using the “Screen saver” setting. The time is given in seconds. Using a very long display screen
saver time may reduce the display lifetime. The default time is one minute.
Fig. 17. The output of 9320 not in use, for example when 9320 is controlling an external set of SAM
monitors.
The “Led brightness (%)” setting controls the brighness of the lighting of the texts next to the keys on
9320A. Selecting the “LEDs Off with Screen” ON turns off the lighting at the keys when the display
banks off. This can be useful when any lighting on the 9320 must be avoided to remove distraction by
