selecting other pages in the drop down menu selector on the far right.

CONTROL MENU 

To manually control the QLI-32 Immersive processor use the Control page
of the web interface. The Front Panel graphic and separate sections show
the current status of the device. All changes to the control settings will be
reflected on the front panel graphic above and on the actual front panel of
the device. Only the SourCe and input mode settings are retained after sys­tem restarts.

8

SOURCE

Choose the expected input type coming from the cinema processor to the
QLI-32. This setting is preserved on system restart.

INPUT MODE

Select the channel format of the source input. Changing the Input mode
state will reset the QLI mode to Normal. This setting is preserved on system
restart.

QLI STATUS

Enable or Bypass Quantum Logic processing or Mute audio output. When
enabled, Quantum Logic immersive processing will be handled by the
device. When bypassed, surround inputs will be arrayed across surround
speakers with an adjustable bypass surround delay. Channel equalization is
applied in either case.

QLI MODE

QLI has been designed to provide a highly immersive cinematic audio
experience with all movie soundtracks. QLI is also equally effective for
Alternative Content such as live broadcasts of music concerts (eg, opera),
theater performances, and sporting events. In some instances, it may be
preferable to set QLI to alternative Content mode in order to obtain an
immersive experience more suitable to this type of content.

SURROUND INPUT LEVEL

Content (movie soundtracks) produced for professional cinema applications
expect the surround loudspeakers to be calibrated to a reference level of
82dB SPL, whereas content produced for consumer applications (DVD/Blu­ray) expect the surround loudspeakers to be calibrated to a reference level
of 85dB SPL. The Surround input level control allows QLI to account
for relative source level differences between Cinema and Consumer (DVD/
Blu-ray) content if a consumer surround decoder is used. Set the Surround
input level control to match the type of surround decoder in use.

The QLI-32 equalization tab allows the user to adjust the equalization
curves of each channel to improve frequency response in auditoriums. The
Real Time Analyzer (RTA) graphic provides 1/3 octave resolution in the fre­quency spectrum for each of the 32 channels of output.

The device factory settings have flat equalization curves and gains at zero on
every channel. It is highly recommended to either manually EQ each chan­nel or run the Auto-EQ procedure to create the best listening experience.

9

SIGNAL GENERATOR

A signal generator exists on each channel with the following types of signals:

• Pink Noise - equal energy per octave noise

• Sweep - 20Hz to 20kHz sweep with 4 second per octave rate

• 100 Hz - sine wave with 100 Hertz frequency

• 1 kHz - sine wave with 1000 Hertz frequency

• 10 kHz - sine wave with 10,000 Hertz frequency

CALIBRATION MIC SETUP

• Step 1

Connect four omni-directional microphones to a microphone multiplexor
device such as the USL MMP-10.

• Step 2

Position the microphones at ear height (3.3-4 ft) in a diamond shaped pat­tern at several locations in the seating area (not closer than 5 ft to any wall
or 16 ft from the screen).

• Step 3

Connect the multiplexor output to the mic input of the QLI-32.

• Step 4

Press the yellow SPL button to calibrate the microphone(s) driving the RTA
while the pink noise generator of the processor is enabled.

• Step 5

Adjust the Microphone Gain control until the indicated SPL matches the
SPL on a reference meter.

NOTE:
*Multiple microphone positions ensures spatial averaging and improves the
overall quality of equalization by reducing the effect of specific room modes.

*All SPL readings are C-weighted decibels at a slow polling rate.

AUTO EQUALIZATION PROCEDURE

With the calibration microphones properly placed and the microphone mul­tiplexor connected to the QLI-32 you are now ready to run an Auto-EQ.

• Step 1

Select the Auto-EQ button on the equalization page.

• Step 2

Using the drop down menus and check boxes select all the channels to EQ.

• Step 3

Select any addition parameters (Gain Smoothing/Centering) to be processed
during Auto-EQ.

10

• Step 4

Select “Go!”. The processor will now go through the Auto-EQ process. Allow
up to two minutes per channel to complete the process.

gain Smoothing - Applies smoothing to adjacent bands to create a more
uniform EQ curve.

gain Centering - Applies a adjustment to the whole EQ curve to center on
0dB.

NOTE:
*All Auto-EQ generated curves target the X-Curve and 85dBc SPL per
SMPTE ST 202:2010 specification.

LFE PARAMETRIC EQ

The LFE channel uses a parametric equalizer instead of a graphic equalizer.
Note that selecting the LFE channel in the equalizer tab does NOT turn
off pink noise on the previously selected channel. This allows pink noise to
drive the LFE and center channels simultaneously so the transition frequency
region can be viewed for possible phase errors. A suggested LFE adjustment
procedure is below:

• Step 1
On the Outputs Tab turn the generator on for both the Center channel and
the LFE.

• Step 2
Navigate to the Equalizer tab and select the LFE channel. The generator
should already be on and pink noise should be visible on the RTA.

• Step 3
At this point, confirm that pink noise is driving both the center and LFE
channels.

• Step 4
Adjust the leftmost (master) gain control until the LFE level matches the
mid-band level of the center channel on the RTA display.

• Step 5
Adjust the frequency control on the PEQ to the worst dip or peak in the
LFE portion of the RTA display. You may use up to four PEQ’s depending
on the amount of peaks and dips in the RTA.

• Step 7
Set the Q and adjust the PEQ gain as required to remove the peak or dip.
The Q can be increased to make the peak or notch narrower, or decreased to
make it wider. The frequency can be adjusted as required to center the peak
or notch on the notch or peak displayed on the RTA.

• Step 8
If there is a notch in the transition region between the LFE and center chan­nel frequencies, try reversing the phase on the LFE channel (Invert button
on the Outputs tab).

• Step 9
Finally, adjust the leftmost gain control up to increase the LFE output as
required. SMPTE RP 200-2002 calls for LFE to be 10dB above the center
channel, but this may be excessive in some auditoriums.

11

COPY EQUALIZATION CURVES

To copy the EQ curve of one channel and apply it to another channel(s)
select the “Copy” button below the RTA graphic on the equalization page.
Note that this only copies the EQ curve of the source channel to the destina­tion channel. The Gain fader level is excluded in the copy.

RTA VIEWING CONTROLS

To adjust the viewing parameters of the RTA mouse over the graphical
area. Here you can zoom in/out, increase the resolution of the Y-axis (dbC),
change the decay, and offset the X-Curve. Smaller decay values will increase
the polling rate while larger values give a more stable value over time.
X-Curve control can be used to move the limit curves up or down to best fit
the current RTA data.

MANUAL OUPUT ADJUSTMENTS 

Visit the outputS tab to manually mute, invert phase, or adjust chan­nel output faders. Channels are categorized into either Stage, Surrounds,
Heights, and Back Surrounds. Grab a fader with a mouse-click and drag
up or down to adjust the gain of that specific channel. Inverting a channel
will invert the phase 180º, helpful if the wiring polarity is backwards on a
speaker.

SENDING TCP AUTOMATION COMMANDS

The QLI-32 is capable of receiving TCP/IP commands from digital cinema
servers or automation controllers if on the same network as the device send­ing commands.

Commands use the following ASCII form: “qli32.sys.command value”.
TCP command strings must be sent to port 10001. To query the current
state of an automation command ommit the value from the string.

For a full listing of all QLI-32 TCP command strings refer to page 27 - TCP
Automation Commands.

BLU LINK I/O

The QLI-32 accepts up to 8 channels of BLU link inputs and outputs up to
32 channels. By default the QLI-32 will be mapped to the following BLU
link channels:
Input channel range: BLU link #65-81
Output channel range: BLU link #1-32

The routing of these channels are fully interchangable within their given
BLU link range. To customize the starting channel of the input and output
ranges or change the mapping within view the Channel Routing section on
page 22.

chosen in SyStem -> general SettingS. After all Auditorium Size, Seating
Area, and Speaker Location values have been entered and saved, values high­lighted in red should be examined for possible mistakes.

NOTE:
*If the Measurment Unit setting is changed after room information has
been entered, all values will automatically converted to the new units.

Define the rectangular dimensions of the auditorium that the QLI-32 is
installed for.

• Width — distance of the left wall to right wall at the front and rear

• Length — distance from the front to the rear of room

• Height — distance from the floor to ceiling at the front and rear

• Rear Elevation — height of floor at rear above the floor at the front

• Reference Listening Position —

X = distance from the theater center line, this should be 0.0
Y = distance from Y origin, normally 2/3rds of room length
Z = height of reference listener’s ears above floor at front, normally
4ft (1.2m) + height of floor at reference position

SEATING AREAS

The next step in calibrating the Quantum Logic engine is to define the seat­ing area(s) within the cinema auditorium. Normally, a room will be suffi­ciently defined within a single seating area.

If there is a gap creating distinct seating areas (i.e. a wide dividing aisle in
stadium seating or a change in seating width due to a side entrance hallway)
then you may define a second or third seating area in the menu. When more
than one seating area is defined, they must be defined in order of front of
theater to the rear (increasing Y values from Seating Area 1 to Seating Area

2).

Input the X, Y, and Z coordinates at the 6 vertices that outline the seat­ing area. The middle vertex will help capture the general shape of a curved
row of seating. The origin point in the room is defined as the center of the
screen at the floor. The coordinates are defined:

X = distance from center line origin (negative value to left, positive to right)
Y = distance away from the screen
Z = height of floor at that vertex above the floor at front

Press the save button when each category is complete before moving to the
next.

SPEAKER LOCATIONS

The last piece of information needed for the Quantum Logic immersive
experience is the number and locations of the speakers in the auditorium.
Like the seating area definitions, the origin point in the room is defined as
the centerpoint of the screen at the floor.

On the dropdown of each speaker category choose the number of speakers
or speaker pairs that exist. Next, enter the X, Y, and Z coordinates for each
speaker defined.

Remember to press the save button before moving to the next category.

NOTE:
*The maximum amount of speakers than can be defined must be less than or
equal to 32.

Screens

• Quantum Logic processing always requires these seven stage speakers.

• Normally, with the Y origin being the front of screen, stage speakers will
have negative Y values.

• If Stage Height speakers are in front of the screen then may have positive
Y values.

• Three screen height channels are a requirement for a Quantum Logic
setup.

• Any speaker behind the screen will need a negative Y value.

Surrounds

• A minimum of two pairs (four speakers) are required.

• A maximum of eight pairs (sixteen speakers) is allowed.

• It is assumed that all surrounds are symmetrical so it is only necessary to
define one surround wall of speakers.

• If the first speaker pair is on the wall between the screen and where the
seating area begins check the Gap box.

• Speaker pairs must be defined from front to rear (increasing Y values).

Heights

• It is assumed that all height surrounds are symmetrical so it is only neces­sary to define one surround wall of speakers.

• A minimum of two pairs (four speakers) are required.

• A maximum of four pairs (eight speakers) are allowed.

• Speaker pairs must be defined from front to rear (increasing Y values).

Rears

• A minimum of two surround speakers are required.

• A maximum of five speakers is allowed.

• Speakers must be defined from rear corner to center of rear wall.

SURROUND SPEAKERS LAYOUT

The figure below is an example of an auditorium using 7 surround pairs, 4
height pairs, and 3 rear speakers. Each speaker pair will have ascending Y
values starting from the front of the auditorium to the rear.

In this example all Height Surround Z values will be equal since they are
mounted at the same level in the auditorium. Lower surrounds 2-7 will have
increasing Z values since they follow the slope of the seating.

CHANNEL ROUTING 

To alter the channel routing within the processor visit the routing tab
within the System Configuration Menu. You are able to edit the following
routing configurations:

• Analog Inputs

• Digital AES Inputs

• BLU link Inputs

• BLU link Outputs

To make an edit to channel routing first choose the category of input/out­put. Next find the channel to re-route and use the drop down menu to make
a change. You may mark a channel as unused if needed.

By default the QLI-32 will have standard SMPTE channel routing
(L,C,R,LFE,Ls,Rs) for inputs. Ensure that the expected input channel rout­ing of the QLI-32 is consistent with the output from your cinema sound
processor.

BLU LINK OFFSETS

The BLU link Input/Output ‘Starting Channel’ dropdown menus allow
for editing the BLU link channels on which the device operates. For input,
match whatever channels the upstream device is sending and make sure the
input starting channel does not conflict.

For example, a default Dolby® CP-850 will output on BLU link channels
1-64. This would require the QLI-32 to have an input starting channel of 1
and an output starting channel of 65. The BLU link amplifiers would also
need to match the output of the QLI-32.

SYSTEM TAB 

The SyStem tab in the System Configuration Menu allows the user to edit
the following:

• General Settings - Change measurement unit and add bypass surround
delay

• QLI Settings* - Edit the Room Factor Adjustment

• Network Settings - Edit IPv4 networking addresses

• NTP Settings - Point the device to a NTP server to syncronize the system
clock

• Site Info - Edit the auditorium name, theater name, and audio processor
type

*NOTE:
Based on Auditorium Size, Seating Area, and Speaker Location information,
QLI automatically configures itself to provide optimal performance. How­ever, not all aspects of the room or playback system can be accounted for
based on this information. The room faCtor adjuSt control is provided to
allow minor adjustments to be made to the automated QLI configuration if
required. For the vast majority of rooms there is no need to alter the room

faCtor adjuSt, and this control can be left to its Auto setting. If needed, the
room faCtor adjuSt should be used as part of the calibration and tuning of

the audio playback system.

22

FIRMWARE UPDATES 

Visit the upgrade tab within the System Configuration Menu to push a
system update to the QLI-32 immersive processor. Press the folder button to
open a file prompt and select the .upd firmware file.

The latest QLI-32 firmware is available at the Lexicon Pro support page.

DIAGNOSTICS 

The diagnoStiCS tab shows detailed system information for troubleshooting
and error checking.

BLU LINK STATUS

The BLU link status menu shows all detailed information regarding the BLU
link chip in the processor. This information may be helpful if troubleshoot­ing BLU link related problems in a system.

• IN/OUT Cable Status — indicates the presence of a valid BLU link con­nection

• IN/OUT Corrected — shows the number of recoverable bit errors that
have occurred

• IN/OUT Errors — shows the number of unrecoverable bit errors that
have occurred

• Lock Source — mastership indicator

• Sample Rate — current sample rate negotiated in the BLU link loop

• BLU link Version — indicates the code version loaded onto the BLU link
chip

• FPGA HDL Version — indicates the code version loaded onto the FPGA

SYSTEM LOGS

The system logs shows various information such as processor core tempera­tures and configuration edits. There are several color coded categories to
improve readabilty.

RESTORE FACTORY SETTINGS 

If unit cannot be found using the prior procedures the following steps will
reset the QLI-32 to its factory settings.

1. Power down the device.

2. Power up the device.

3. Immediately hold the QLI button down until the light sequence ends and
all lights blink solid (about 10 seconds).

4. The system will now have Factory Default Settings.

NOTE:
*Reverting the device to Factory Settings will cause all saved settings to be
lost. It is recommended to save a backup beforehand.
