Service Information
The DaySequerra MultiMerge2 contains no user serviceable components inside the unit. Please
contact DaySequerra for repair and upgrade information. In the event that your unit needs to be
returned to the factory, contact us for a return authorization number. Please visit
www.daysequerra.com and register your new MultiMerge2 so we can keep you informed of the

The lightning flash with arrowhead symbol is intended to alert the user to the presence of un-
insulated “dangerous voltages” within the product’s enclosure that may be of a sufficient level
to cause harm.
The exclamation point within a triangle is intended to alert the user to the presence of important
operating and maintenance instructions within the
product literature.
Exposed portions of the power supply assembly are
electrically live. To reduce risk of electric shock, the
power cord must be disconnected when the power
supply assembly is removed. For continued
protection against electric shock, a correctly wired
and grounded (earthed) three-pin power outlet must
be used. Do not use a ground-lifting adapter and
never cut the ground pin on the three-prong plug.
The ground terminal of the power plug is connected
directly to the chassis of the unit.

Introduction
The DaySequerra MultiMerge2 enables broadcasters to smooth the transition from stereo to 5.1
surround sound by providing viewers with a 24/7 surround sound experience. With MultiMerge2 inline,
5.1 original content is passed unaffected to the viewer while original stereo content is UpMixed to a 5.1
surround sound image providing the viewer with a consistent surround experience. The transition
between 5.1 and stereo occurs seamlessly without the need of operator intervention. By offering a 24/7
5.1 signal, AC3 metadata will never need to transition between 2/0 and 3/2 mode avoiding the risk of
audio ‘clicks’, ‘pops’, and dropouts.
The DTS-Neural Audio patented approach to stereo UpMix avoids taking ‘artistic license’ with content
by placing audio exactly where it would be heard in a professional LEDE (Live End Dead End) listening
environment. For example, mono or pan-pot stereo will image in front of the listener where as stereo
containing depth information, or LtRt encoding, will surround the listener.
The MultiMerge can be used in combination with the DTS-Neural Surround DownMix to in order to pass
5.1 through stereo only facilities thus, eliminating the need for costly Master Control upgrades.
Broadcasters need a solution to effectively measure, and ultimately control the abrupt changes in
loudness that sends viewers diving for their remote controls during commercial breaks and action
scenes. The MultiMerge 2 + NLC surround loudness control simultaneously measures the perceived
loudness of 5.1 surround program audio along with 2.0 auxiliary stereo using the industry-standard ITU-
R BS.1770/1 loudness measure or the DTS-Neural Loudness Measure (NLM) algorithm.
MultiMerge 2 plus Neural Loudness Control uses the proprietary DTS-Neural Loudness Control, an
advanced loudness-leveling algorithm, to apply the appropriate gain or attenuation to maintain the
broadcaster-defined loudness level. The resulting audio has a naturally open, dynamic quality without
the annoying side-effects of traditional energy-based volume management solutions.
Loudness is a perceptual property of an audio signal when it is reproduced acoustically. It is a complex
non-linear function of amplitude, frequency and bandwidth. Current audio level meters measure the
level of audio signals expressed as the amplitude of the signal - either the RMS (root mean square)
voltage of an electrical signal or the sound pressure of an acoustical signal. Neither of these
measurements, although widely accepted, provides accurate indications of how viewers will perceive
the loudness of the audio programming.
The DTS NLM algorithm uses a perceptual model of human hearing to more accurately detect spectral
and density differences, inter-channel relationships and temporal overlaps in any audio content,
resulting in a more accurate perceived loudness measurement over time. This proprietary algorithm
was developed by after extensive research into human hearing and perceived loudness.
To improve system reliability and up-time, MultiMerge 2 + NLC uses a robust DSP-based processing
platform rather than a PC-based approach to completely avoid broadcast disruptions caused by
operating system lockups. An Ethernet interface provides long-term logging and field software updates
capability. An optional factory-installed HD/SDI module will allow for measurement of 8 channels of
program audio from group 1 or group 2 with user specified mappings within the group. A set of user-
definable alarms can alert an operator of input loss, signal clipping and high or low signal levels
referenced to the desired loudness level.
When MultiMerge 2 + NLC is used ahead of an AC3 (Dolby Digital) transmission, the target loudness
level will also match the Dial-norm metadata information, thus providing consistent, enjoyable audio for
all viewers.

Installation
Immediately upon receiving your MultiMerge2, please make a careful inspection for any shipping
damage. If damage is found or suspected, please notify the carrier at once and then contact your
dealer. MultiMerge2 is shipped in one carton, which contains: the MultiMerge2 unit, an AC power cable,
and this Users Manual.
We strongly encourage you to save the shipping carton and shipping materials supplied with your
MultiMerge2. They are specially designed to properly protect your MultiMerge2, and in the event that
you need to return it for service, only these OEM shipping materials can ensure its safe return to our
factory.
We provide a limited 3-year warranty on all of our products; however, if you don’t register your unit, it is
impossible for us to contact you to notify you when important software upgrades become available.
Please take a few minutes to complete the warranty registration form on our website,
www.daysequerra.com.
Rack Mount Installation
The MultiMerge2 chassis has four rack mounting holes and has been designed to fit in a standard 1RU
space. Plastic ‘finishing’ washers are recommended to protect the painted surface around the mounting
holes. Locate the air vents on each side of the unit, and be sure to keep them clear so the unit may
have adequate ventilation.
Power Connection
The AC power cable supplied with MultiMerge2 must be connected from the IEC320 power entry
module to an AC mains outlet with a functional earth ground connection. For protection against electric
shock and electro-magnetic interference, do not plug the power cable into a ground-lifting adapter or
remove the cable’s grounding pin. If in doubt, please consult a qualified electrician.
Please connect MultiMerge2 to an uninterruptible power supply (UPS) to protect against power
surges and low-voltage conditions. MultiMerge2 may be combined with other devices on the output
of the UPS as long as the total load is within the UPS’ capacity. Consult your UPS manual for details.
MultiMerge2 will automatically power up when AC power is applied. If AC line power is lost or
momentarily interrupted, MultiMerge2 will revert to its previous state.

clock signal from an external source and pass it on to other devices.
The AES-3id-1995/SMPTE 276M standard dictates a 75Ωunbalanced connection and requires proper
termination. The termination should occur at the destination of the signal (that is, on the inputs to
Multimerge 2). If the loop-through BNC connectors are not feeding additional equipment, terminate
each of these with a standard 75Ωterminator. Like other inputs, HD/SDI signal should be terminated.
