Linear Acoustic UPMAX v4 User Guide Introduction

Chapter 1: Introduction
The Linear Acoustic UPMAX v4 produces a 5.1 channel audio signal that is perfect for
eventual transmission to all consumers. The unit accepts a 2-channel input and “upmixes”
it to fill as many of the 5.1 output channels as the user selects. Any input signal from mono
to stereo to LtRt (Left Total/Right Total) surround encoded audio and even three channel
(M&E plus Dialog) can be applied to the Main Inputs and an output will be produced that
maintains consistency with other 5.1 channel programming.
The UPMAX v4 provides the following features:
• Advanced upmixing algorithm for stable, convincing surround experience.
• Fully downmix compatible
• Upmixed surroundfield is infinitely adjustable
• External inputs allow crossfaded bypassing of upmixing to enable discrete 5.1 channel
audio to pass untouched, or mixing of external and upmixed content
• Built-in independent LoRo/LtRt encoder
• Relay bypassed I/O for “mission critical” broadcast applications.
• HD/SD-SDI I/O for audio and metadata
1.1 Principles of Operation
The UPMAX v4 contains two paths for audio signals. The first path contains an upmixer,
a bass extension filter to create the LFE (Low Frequency Effects) or subwoofer channel,
and a simple but powerful set of mix controls to vary each element of the surroundfield.
The second path provides discrete inputs for the Center, LFE, Ls (Left Surround), Rs
(Right Surround), Lf (Left Front) and Rf (Right Front) channels. The upmixed and discrete
outputs can be crossfaded between to allow smooth transitions between upmixed and dis-
crete audio.
Please refer to Figure 1-1. It should be noted that this diagram is a general representation
of signal flow. Please consult the appropriate section of this manual for an accurate de-
scription of actual functionality.

Chapter 2: Connections and Quick Setup
This chapter covers all required connections for the UPMAX v4.
2.1 Unpacking and Inspection
Before unpacking the unit, inspect the outer carton for shipping damage. If the carton
shows damage, inspect the unit in those areas. Please save the carefully designed shipping
carton and packing materials. In the unlikely event that the unit needs to be returned to the
factory, alternate cartons or packing materials may not be adequate and can cause damage
not covered by warranty.
The following essential items are provided with the unit:
• Bag containing:
• Quick-start sheet to get you up and running
• Two IEC power cords (style matches country of order);
• USB stick with this manual
• Spare fuses and a handy black pen.
• Warranty information: Please fill out and return the warranty card to Linear Acoustic
to ensure your software and documentation are kept up to date.
2.2 Installation
UPMAX v4 installation requires:
• One standard rack space unit with ADEQUATE VENTILATION (the unit relies on
convection cooling from side-panel vents);
• standard 75-Ohm BNC cables for digital signal connections;
To connect to digital equipment with 110-Ohm XLR connectors, use impedance-
matching transformers (available from Canare, Neutrik and other manufacturers).
• Proper reference. The unit will default to internal 48kHz with no signals applied, but
AES 1/2 or SDI can be used as the reference. For proper plant timing, proper refer-
ence selection in imperative. Note that if SDI embedding is active, clock source will
automatically be forced to SDI.

2.3 Rear Panel
The rear panel of the UPMAX v4 contains its electrical I/O.
2.3.1 Connection Ports
All of the UPMAX v4’s connections are on the rear panel and are described in detail below.
See Chapter 5: Specifications for specific pinouts.
Figure 2-1 Rear Panel
•Metadata I/O: RS-485 connection accepts the metadata output of any SMPTE
RDD6 (i.e. Dolby) compliant metadata source. Can be used to control upmixing and
recall of presets.
•SDI Input/SDI Output: Allows access to all 16 audio channels for embedding and
de-embedding. VANC metadata per SMPTE 2020 can also be extracted.
•GPI/O: Connect dry contact closures here to control upmixing on/off. Note that
GPI functions require held closures for the duration of the desired function. Status of
GPI will be reflected on the corresponding GPO pin.
•ETHERNET: Used for software upgrades and SNMP monitoring.
•Main Audio Input: Connect the 48kHz PCM signals to these inputs. The input chan-
nels are arranged as follows: 1/2 = Left front/Right front, 3/4 = Center/LFE, 5/6 =
Left surround/Right surround, and 7/8 = Stereo Aux input.
NOTE: Appropriate reference should be applied AND selected for proper operation.
•Main Audio Outputs: Main 48kHz processed digital audio outputs. 1/2 = Left
Front/Right Front, 3/4 = Center/LFE, 5/6 = Left Surround/Right Surround.
• 7/8 (LoRo/LtRt) Output: A two channel downmixed version of the audio applied
to Inputs 1-6, or a time-aligned passthrough of the 7/8 input.
•Monitor Control: Remote control of analog volume, mute, and return to reference us-
ing a standard rotary encoder, switches, and LEDs (with series resistors). A suitable
high-quality remote control is available from Linear Acoustic.

•Analog Monitor Outputs: A +4dBu balanced analog version of outputs 1-8. Volume
can be controlled from the front panel joystick encoder or via the Remote port.
2.4 Quick Setup Notes
The Linear Acoustic UPMAX v4 is configured at the factory and is ready to go on the air
after making the proper input and output connections and determining if upmixing is de-
sired.
• Apply a two-channel (stereo or LtRt) signal to Main Input 1/2
• The main menu will default to showing output meters, and you should see activity on
some or all of the first six meters.
• Upmixed audio will be output from the Main Out 1-6 AES outputs in the following
format: 1/2 = Left Front/Right Front, 3/4 = Center/LFE, 5/6 = Left Surround/
Right Surround
• You will also have audio on the analog outputs in the same format as above.
The best way to learn the processor is to explore the different settings with audio applied
and monitored. There are several factory presets to support many different tastes. Some
presets may not sound much different at first, but will perform very depending on program
content. When in doubt, try turning the upmixing process off or as a last resort use the
Master Bypass feature which will remove the UPMAX v4 completely from the signal path.

Chapter 3: Applications
The UPMAX v4 is intended to be used either in the production or distribution stages of
5.1 channel programming, and also selectively in transmission environments. Cable and
satellite facilities may find it useful as the distribution and transmission sections are usually
very close together. For terrestrial emission (transmission) applications such as at DTV sta-
tions, the Linear Acoustic AERO series of processors may be a more appropriate choice
as they contain requisite loudness control, dynamic range processing and additional useful
features such as Dolby encoding and decoding.
The Linear Acoustic UPMAX v4 is not a substitute for a good, discrete multichannel mix
(if one is available), however it is a useful tool for creating one.
That being said, the UPMAX v4 is an excellent tool useful in either creating a 5.1 channel
version of a program when few or no other elements exist, and also for creating a solid
foundation for a true discrete multichannel mix.
This chapter discusses several applications of the UPMAX v4:
• General application notes
• Integrating 2-channel commercials into a 5.1 channel program
• Creating a 5.1 channel sports program from stereo plus natural sources
• Use for music programming
• Discussion of presets stored in the unit
3.1 Typical Scenarios
Below are some application examples to give users some guidance in real-world situations.
However, before continuing, it is absolutely imperative that a proper multichannel moni-
toring environment be set up and calibrated before every mix. If the mix cannot be heard
properly, then it cannot be created properly.
The Linear Acoustic UPMAX v4 is useful almost anywhere a multichannel mix must be
created. From hands-on adjust-as-you-go environments like a music awards program to
set-and-forget applications like helping two-channel commercials fit into 5.1-channel pro-
gramming, the UPMAX v4 is the answer.

Linear Acoustic UPMAX v4 User Guide Applications

3.1.1 General Notes
The latency of the UPMAX v4 has been kept as low as possible. To take best advantage of
this, make sure it is installed in a synchronous system (i.e. as a send and return to a console)
and set the Sample Rate Converter Bypass to ON (i.e. SRCs are off). This will keep the
latency at around 4msec. Make sure to take care not to bring up both the send and return
audio else even this very low 4msec might cause comb filtering.
In general, an upmixer responds to level to control Left to Center to Right positioning, and
phase to control front to back positioning. UPMAX v4 operates across multiple bands to
minimize low frequency content causing center channel build-up. However, dialog can do
the same thing, especially announce dialog. It was discovered some years ago that simply
separating a mix into two parts: Main Stereo (no announce) and a separate Announce chan-
nel then upmixing only the Main Stereo and combining with a time aligned version of the
Announce audio produces a very wide and stable result free of odd sounding artifacts.
3.1.2 Two-Channel Interstitial Programming
One of the largest complaints viewers is the annoying fact that stereo commercials don’t
seem to “fit” into the 5.1-channel program. This is because in many cases, the commercials
are simply transmitted on the Left and Right channels of a 5.1-channel program. The net
result is that during the program, dialogue comes from the center speaker, but at commer-
cial or station breaks, all of the dialogue comes from the left and right speakers. It can be
a jarring experience.
The first application is one where the UPMAX v4 processes the stereo material allowing
it to fit nicely within a 5.1 channel program. Figure 3-1 shows this scenario. Note that the
two channel material is simply input to the UPMAX v4 and a 5.1 channel signal is available
at the output. Either of the Commercial or Music presets can be chosen, and are ex-
plained in detail at the end of this chapter.
3.1.3 Sports Production
Sports production could be as simple as creating an excellent and wide stereo mix with di-
alog on a separate bus. Using the UPMAX v4, the stereo mix can be turned into 5.1 and
the announce audio passed around the upmixer.
A Center Detect control was added to the Auto mode to facilitate handling this type of 3-
channel audio. It ignores the presence of audio on channel 3 (i.e. the announce audio), time
aligning it and summing it with the upmixed version of the audio from input channels 1-2.
This mode is also useful if the audio might be of several different flavors. With Center De-
tect set to off, Stereo, 3-channel, and 5.1 channel input audio can be automatically handled
with no operator intervention. A tip would be to adjust the crossfade timing to be as fast
as practical.
