Important Safety Instructions
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings, Install following the
manufacturer’s instructions.
8. Do not install near any heat source such as radiators, heat
registers, stoves, or other apparatus (including amplifiers)
that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding type plug. A grounding type plug has two
blades and a third grounding prong. Use the correct plug
supplied. If none of the provided plugs fit into the outlet,
consult a qualified electrician for replacement of the
obsolete outlet.
10. Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the
point where they exit from the apparatus.
11. Only use the attachments/accessories specified by the
manufacturer.
12. Unplug this apparatus during lightning storms or when
unused for long periods.
13. In rack installations leave 1u of rack space above and
below for proper ventilation. If stacking more than one
amplifier, the same 1u of space must be maintained
between each amplifier. If installed in a bookcase, ensure
adequate ventilation as described below and maintain 1u
clearance between units when stacked. Leave 8” (20cm)
of free space at the top (or top of stack) and sides and 4”
(10cm) at the rear. The rear edge of the shelf or board
above the apparatus should be set 4” (10cm) away from
the rear panel or wall, creating a flue-like gap for warm air
to escape. Good airflow is necessary to help ensure proper
operation. A proper installation plan will provide enough
free space around the unit and ensure air flows freely and
is able to escape from the amplifier surroundings. Failure
to do so may cause thermal shutdown of the unit, or
reduced life expectancy. Avoid stacking if possible.
14. Never expose the unit to moisture.
15. Refer all servicing to qualified service personnel. Servicing
is required when the apparatus has been damaged in any
way, such as power-supply cord or plug is damaged,
liquid has been spilled or objects have fallen into the
apparatus. The apparatus has been exposed to rain or
moisture, does not operate normally, or has been
dropped.
16. Damage requiring service.
Unplug the apparatus from the wall outlet and refer
servicing to qualified service personnel under the
following conditions:
A) when the power supply cord or plug is damaged,
B) if liquid has been spilled, or objects have fallen into
the apparatus,
C) if the apparatus has been exposed to rain or water,
D) if the apparatus does not operate normally by
following the operating instructions. Adjust only
those controls covered by the operating
instructions as an improper adjustment of other
controls may result in damage and will often
require extensive work by a qualified technician to
restore the apparatus to its normal operation,
E) if the apparatus has been dropped or damaged in
any way, and,
F) when the apparatus exhibits a distinct change in
performance, this shows a need for service.
17. Objects and/or Liquid Penetration.
Never push objects of any kind into the apparatus through
openings as they may touch dangerous voltage points or
short-out parts that could result in a fire or electric shock.
The apparatus should not be exposed to dripping or
splashing and no objects filled with liquids, such as vases,
should be placed on the apparatus.
Do not put candles or other burning objects on top of this
apparatus.
WARNING:
TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK. DO NOT EXPOSE THIS APPARATUS

Precautions
1. AC Fuse
The AC fuse inside the unit is not user-serviceable. If the unit will not turn on, contact the dealer the unit was purchased from.
2. Care
Occasionally dust the unit all over with a soft, lint free cloth. For stubborn stains unplug the unit, use a soft cloth slightly
dampened (no dripping) with a weak solution of mild detergent and water. Dry the unit immediately afterwards with a clean
cloth. Don't use abrasive cloths, thinners, alcohol, or other chemical solvents, because they may damage the finish or remove the
panel lettering.
To clean the touchscreen use a standard glass cleaner, but avoid products containing ammonia. Always spray the glass cleaner
on the cloth or towel and then clean the touchscreen using a light-touch circular motion. Avoid spraying glass cleaner directly
on the touchscreen. TIP: The Lock-out Mode can be used to avoid system navigation when cleaning the touchscreen.
3. Power
a. WARNING: BEFORE PLUGGING IN THE UNIT FOR THE FIRST TIME – READ THE FOLLOWING SECTION CAREFULLY.
b. AC outlet voltages vary from country to country. Make sure that the voltage in installation area meets the voltage
requirements printed on the unit’s rear panel (e.g. AC 85V~240VAC 280 watt continuous. 50 - 60HZ).
c. The power cord is used to disconnect this unit from the AC power source. As this unit does not have an AC power switch,
make sure the plug is accessible at all times in case power must be turned off quickly to the unit.
d. If unit is not used for an extended period, remove the power cord from the AC outlet.
4. Earth Ground
The unit is defined as Class1 in EN60065 (low voltage directive) and the power supply MUST BE EARTH GROUNDED. Connect
only to a mains socket outlet with protective earth, and only use the power cord supplied.
5. Never Touch this Unit With Wet Hands
Never handle this unit or its power cord with wet or damp hands. If water or any other liquid gets inside this unit, have it

SECTION 1 – Quick Install Overview
Congratulations on purchasing Vantage's 850D-DA, Digital
Distributed Audio Amplifier. Please read this manual
thoroughly before making connections and plugging in the
unit. Follow the instructions in this manual to obtain optimum
performance and enjoyment from the new Vantage, 850D-DA
amplifier. Please retain this manual for future reference.
Unpacking / Setup
Check for damage:
oImmediately upon receiving the new 850D-DA Digital
Distributed Audio Amplifier, inspect the carton for
evidence of mishandling during shipment.*Then
carefully unpack the unit and inspect for damage.
Please save the shipping carton and all inner packing
materials in the event that the 850D-DA needs to be
shipped for service or moved to a new location.
*IMPORTANT: If the 850D-DA digital amplifier has been
damaged during shipping, please contact a
Vantage supplier immediately.
Read this entire Instruction Manual.
Verify that all accessories have been included, see, Preface
and Safety Instructions / Supplied Accessories.
Connect sources 1-8 using RCA Coax Digital Audio and/or
analog stereo. Connect sources 9-12 using Optical Digital or
RCA Coax Digital Audio. RCA Coax Digital connections are
RCA type SPDIF (S/PDIF-Sony/Phillips Digital Interface, aka
SPDIF) See SECTION 4 – Rear Panel Guide and SECTION 5 –
Installation Example.
NOTE: Sources 1-8 can accept two physical connections from
the same source when the source has both analog and digital
outputs. Depending on the media being played, the signal may
be encoded or un-encoded. The 850D-DA will automatically
select the correct source. If the signal sent is Encoded Digital
Audio, the amplifier automatically uses analog. If the signal is
un-Encoded the amplifier automatically uses the digital source.
Connect zones 1 – 6 to speakers via high quality speaker
audio cables (e.g., 16awg stereo audio cable or better).
oUse recommended wire size for distributed stereo
systems (use table above).
oWhen possible, keep LEFT and RIGHT speaker runs, in
that zone, the same length.
oAvoid crimping speaker wire (sharp 90bends should be
avoided)
oGenerally, in-wall speaker wire should be CL2R or CL3R
rated speaker wire. Check with local authorities for
distributed speaker wire rating requirements.
oSpeaker wire should be properly distanced from RFI
and/or EMI interference (e.g., keep at least 12" (305mm)
away from parallel high voltage house wiring).
In rare cases, if RFI and/or EMI interference is
unavoidable, the use of shielded speaker cable wire
may help, test first.
oDo not connect dual-coil speakers with shared left and
right channels for common. Speaker connections can
not be combined. In other words, the common/ground
speaker terminals from right channel and left channel
can not be paralleled/combined. In this amplifier,
speaker ground outputs are not common.
oZone 7 and Zone 8 are line-level outputs. Use high
quality shielded cable made for line level runs. Line level
wire run lengths are not published and must be tested
for noise and suitability. Vantage also recommends
using Stereo Audio Baluns for long, line-level runs.
Connect unit to the local network via the Ethernet port.
Connect Power cord to unit and then plug into an AC outlet
to apply power.
Connect / Configure unit to the InFusion System;
oVantage Controller using Ethernet;
Do not attempt to assign an IP address. A DHCP
address is assigned by the router or the 850D-DA
obtains an “AutoConf” IP address in a reserved range
the InFusion Controller can see.
Type the 850D-DA’s serial number in the Object
Editor inside of Design Center. The 850D-DA will
come on line when the InFusion controller is
programmed, or
Program the system and then click on Configure
Stations in Design Center. With the 850D-DA
highlighted in Design Center press the configuration
button which shows up on the touchscreen of the
amplifier or, press the Config. button on the back of
the 850D-DA (see page 5).
Special Notes For Setup
When replacing an 850D-DA amplifier in an existing
installation or adding as a new unit to an existing
installation, confirm that all firmware is the same on all
850D-DA, Digital Distributed Audio Amplifiers.
oFirmware is updated through Design Center software.
Use firmware that has been suggested for the version of
Design Center used on the current project.*To
determine which firmware is loaded, go to SECTION 7 –
Front Panel LCD Touchscreen Guide / Systems Settings
Page / Device Information Page. If updates are needed
or wanted, check the Vantage Dealer website for the
latest release of Design Center.
*NOTE: All firmware files, in each release of Design Center,
are the recommended versions at the time of
release. Some newer or older versions of firmware,
Driver Tools, Vantage InFusion Media etc. may or
may not be fully compatible. Vantage recommends
keeping all firmware versions as current as possible
and at the same time, use the firmware versions
recommended for the specific release of Design
Center used on each project. Please check the
Vantage Dealer Website for firmware updates,
http://dealer.vantagecontrols.com. Contact a
Vantage dealer for additional questions on
compatible firmware versions.
Each 850D-DA ships with 8 zones, 12 sources and 1
MediaPlayer (streaming network / NAS) source already
setup by default. When the 850D-DA is configured,
programmed and on line with the InFusion System, Design
Center automatically addresses the audio zones 1 through 8,
whether a single or multiple units configuration is used.
oWhen adding multiple 850D-DA units in Design Center,
the zone names are identical for each additional unit
added (i.e., Zone 1, Zone 2, Zone3, etc. is assigned for
each 850D-DA added). From Design Center, rename
the new zones, to help identify them properly when
programming. Design Center is able to differentiate
each zone due to unique VID numbers and parent ID,
but unique names will make selecting the correct zone
more intuitive to the programmer and client.
The 850D-DA has an onboard digital MediaPlayer source for
streaming local NAS (Network Attached Storage) music on
the local network via its Ethernet connection.

SECTION 2 – Features 850D-DA
850D-DA Digital Distributed Audio Amplifier
Installation Manual 41316 / 1308134-A © 2011 Page 2
SECTION 2 - Features
Multi-Zone, Multi-Source, Switching
The 850D-DA amplifier has six separate amplifiers and two
separate preamplifiers, providing 8 zones of independent yet
integrated control.
There are 12, buffered, input/output sources plus one
streaming source comprised of the following.
Sources 1 - 8 are either Analog Stereo (RCA), or Coax
(SPDIF) Digital Audio, or both.1
Sources 9 - 12 are either Coax (SPDIF) or Optical Digital
Audio.
Two contact inputs for door bells, etc., may be
programmed to internal decoded streams (virtual inputs)
by setting up page 1 and/or page 2 parameters. Up to four
door bell sound files may stored and each file may be up
to 480 KB in standard WAV format.
1NOTE: Sources 1-8 can accept two physical connections from
the same source when the source has both analog and digital
outputs. Depending on the media being played, the signal may
be encoded or un-encoded. The 850D-DA will automatically
select the correct source. If the signal sent is Encoded Digital
Audio, the amplifier automatically uses analog. If the signal is
un-Encoded the amplifier automatically uses the digital source.
Onboard MediaPlayer Digital Streaming Source
Vantage’s 850D-DA has an onboard digital media source, via
the local Ethernet connection, adding the ability to stream
most network based audio files. Please note, the onboard
MediaPlayer supports audio files with 1 or 2 channels and a
sample rate of ≤48kHz.
On Source Unit 1, the MediaPlayer Source has the ability to be
linked and buffering through multiple 850D-DA units playing,
synchronized, across each unit’s zones assigned to source 12.
Please see Section 6 and Section 8 for additional detail.
TIPS:
The MediaPlayer (streaming network) source via the
Ethernet connection is a streamed source comprised of
sound files which are not compressed or changed in
quality by streaming over the local network.
This source uses a network storage device or similar
connected music source to play media files, AKA, NAS
storage devices.
Supported File Types: Ogg Vorbis, MP3, MP1/MP2, MPEG4,
HE-AAC v2, WAV and FLAC.
oThe onboard MediaPlayer supports audio files with 1
or 2 channels and a sample rate of ≤48kHz.
Organize music files on the NAS device into folders. When
organizing the songs for each folder of music on the NAS
drive, think of each folder as a Playlist or Genres. This will
allow a better interface, allowing the user to select a UNC
knowing what music/type will be streamed. See Section 7 |
MediaPlayer Page for UNC setup.
Streaming supports Previous, Next, Pause, Stop, and Play.
If Stop is selected instead of Pause, the next time Play is
pressed the playing list starts over.
Preamp Zones and Amplified Zones
Each output zone supports, independent bass, treble,
loudness, balance, volume, maximum volume, and mute
control. Each output has a delay feature; range is from 0ms to
315ms. These settings are accessed through Design Center
programming or through the front panel program. The
maximum volume setting is useful for protecting connected
speakers. It may be applied to both amplifier and preamplifier
outputs.
Amplifier Power, Protection, and Clipping Indicators
Each zone supports 50Watts per channel at 8 ohms and is
capable of being driven into 6 or 4 ohm loads. The amplifiers
are protected against short-term output shorts. The front panel
zone indicators will momentarily turn red when the zone
amplifiers are over-driven into clipping. The amplifiers have
programmed algorithms that prevent hard clipping when the
zone amplifiers are over driven.
Thermal Control: Power Inputs and Zone Outputs
This unit has built-in thermal protection for low voltage, high
voltage, and two progressive levels for zone outputs.
Description of zone output protection levels:
LEVEL 1 - The amplifier volume is reduced 20dB.
LEVEL 2 - All internal amplifiers are shutdown until the
temperature reduces below the first level.
Care should be taken to ensure adequate ventilation - see
"Important safety instructions" at the beginning of this
Instruction Manual.
Ethernet Bus, USB, and IR Control
The 850D-DA amplifier may be controlled and monitored from
InFusion Design Center, touchscreens, mobile interfaces, the
unit’s front panel touchscreen, and the USB*on rear panel. IR
control is also possible but does not provide system status
feedback.
* The USB connection is for diagnostic purposes
and is not used with a Vantage InFusion System.
In multi amplifier installations - where the amplifiers are
interconnected via SPDIF - each of the 850D-DA amplifiers
require a connection to the local network in the stack of
amplifiers.
In standalone installations, an 850D-DA amplifier may receive
IR directly from the receiver on the front panel of any amplifier
and pass the information to other 850D-DA units in a stack if
the units are connected via the expansion bus. There are zone
specific IR commands and also a set of global IR commands.
Zone Specific
IR Commands:
ON, OFF, Standby (toggling),
Mute, Amp Volume Up, Amp Volume Down,
Pre Volume Up, Pre Volume Down,
Source Selects
Global IR
Commands:
PRESET 1 – PRESET 6,
Alarm Enable, Alarm OFF, & 5 minute Sleep
Real Time Clock Applications
Using the InFusion Controller’s internal real time clock or
astronomical clock, the amplifier may be setup to function as
an alarm clock. Alarm clock programming possibilities are
potentially limitless in Design Center software. The InFusion
System clock continues to operate up to 2.5 years un-powered
(dependent on the InFusion Controller battery’s condition).
The 850D-DA amplifier is also equipped with a real time clock.
The InFusion controller periodically sends time information to
the amplifier keeping the amplifier’s time synchronized with
the InFusion System. The amplifier may be set up to function
as an alarm clock via the front panel and from Design Center.
For example, at 6:30am in the morning, five days a week, the
master bedroom zone could be made to turn on using
programmed parameters (e.g., select tuner, specific volume
level, etc.). Multiple Alarms are feasible (max. of 14). The Clock
can be set to automatically compensate for daylight saving.
The clock continues to operate, typically > 48 hours, without
power - more than enough to keep the time current during
extended power outages.

Presets and Paging
There are fourteen amplifier presets and two Page presets..
NOTE: To properly setup Presets from Design Center, the
amplifier must be connected and configured to the system.
1. 14 Program Presets.
a) Page 1 and 2 use 1 of 4 uploaded sound files, however
Page 2 must be assigned to one of the other 14
Presets.
i. Page 1: Select 1 of 4 sound files to automatically
play when triggered by a contact, typically a Door
Bell or from a programmed task, time control, etc.
ii. Page 2: Select 1 of 4 sound files to automatically
play when triggered by a contact and must be
assigned to one of the 14 Presets. Page 2 may also
be triggered from a programmed task, time control,
etc.
b) All Presets may be tied to internal programmed alarms
or InFusion programmed alarms for specific time of
day execution.
i. Please note that output zones have a Do Not
Disturb feature that may be toggled, allowing or
preventing a programmed alarm in that zone.
ii. Alarms support Time (including daylight savings)
and individual Day of Week setup.
c) Presets can be named through Design Center software
2. Preset Feedback reports to the InFusion Controller
through the Ethernet Bus
Zone Linking
Zone linking is part of the Zone Settings menus and ties all
selected zones together. A zone may be setup to link with any
combination of zones or all zones. The zone that is being
actively edited determines the source of the other linked
zones. Linked zones can also link volume and/or standby,
however the volume and standby may be left independent of
the zone link. This is useful for closely coupled audio areas
where it is advantageous to have different volume control but
the same source, or the same volume with separate standby
control, and etc. Zone linking from Design Center’s Procedure
Wizard (tasks) allows source, selected zones, volume and
standby in any combination. Zone linking is not possible from
Design Center’s Live Source Control; see Section 8 for
information about Live Source Control.
72 Maximum Number of Zones
The system may be expanded up to 72 zones (nine units) of
possible control. Through Design Center and the InFusion
system each zone on the 850D-DA amplifier, is different or
independent, even when they have the same name. However,
in a standalone installation, multiple amplifiers connected via
the expansion bus, share the same zone names causing the
zones to mimic each other and act as a single zone unless
renamed through the front panel user interface. To reiterate,
when using an Infusion Controller, the zones may have the
same name, but the zone’s address is assigned by the Infusion
Controller and duplicate zone IDs are not allowed.
Expansion Bus
On the InFusion System, multiple 850D-DA amplifiers may be
linked or distributed throughout the project as separate,
independent, units. In a linked configuration, the source
equipment’s audio outputs must be plugged into the first
amplifier where they are buffered and sent to the next
amplifier. The maximum number of linked units is nine. When
linked, each unit is connected to the next using a standard
Ethernet patch cable to and from the Expansion Bus ports to
enable communication among multiple amplifiers. Linked or
separate, Vantage requires that each unit be connected to
the local network via a standard Ethernet connection.
Conversely, the Expansion Bus is not used on the 850D-DA if
the units are independent and each unit must have its own
audio source equipment.
Zone ON Outputs - “Amp-On”
Each zone has connections for AMP-ON status: 12VDC OUT on
the rear panel connector: (1, 2, 3, 4, 5, 6, 7, 8). These outputs
activate a secondary AMP (e.g., the Vantage 7+7 Watt
Amplifier Series, part number AX-07S). The OV terminal is the
common (shared) terminal for the 8 AMP-ON terminals. Please
note that the AMP ON outputs are protected against shorts.
Power Failure Restoration
After an AC power outage the 850D-DA amplifier restores its
settings to the pre-interrupted state. All internal settings are
stored in non-volatile memory, except the clock that runs for
at least 48 hours on stored power. When power is restored the
unit will always reset its internal clock to the InFusion
Controller’s time.
Restore Defaults
The 850D-DA amplifier may be readily set to the default
settings. Factory defaults resets the zone allocations back to
1 - 8, clears all zone and source names, presets, zone links,
maximum volume limits, bass, treble and loudness settings. See
SECTION 7, Front Panel LCD Touchscreen Guide.
Setup Lockout
Locks access to the System Setup menus where critical
installation adjustments can be made. A press and hold for
about 5 seconds on the Lock icon will unlock the setup.
Firmware Upgradable
The 850D-DA’s firmware may be updated via Design Center
over the Ethernet Bus connection. Please check the Vantage
Dealer site for firmware updates. Typically the latest release of
Design Center will have the latest 850D-DA firmware. See
SECTION 1 / Special Notes For Setup.

Door Bell
Up to four door bell sound files may be stored directly on the
850D-DA. Each sound file may be up to 480 KB in standard
WAV format. Upload door bell sound files to the 850D-DA via
Design Center software. The sound files may be played back
by Page 1 or Page 2 programming.
It is also possible, through Design Center programming, to play
any source file through any of the 850D-DA amplifier zones as
a result of either page 1 or page 2 contact closure triggers. Use
this method for door bell sounds as an alternative to copying
the page sound files directly to the 850D-DA’s own page file as
the source (e.g., play a sound file from Vantage’s DMM).
Page 1 and 2 require an outside 12-24V AC/DC power supply.
The contact closure must have an external power source, (i.e. a
12 – 24V AC/DC powered door bell). When the Page Call is
released the amplifier zones return to their previous states.
PG1 is always assigned to the Page 1 Preset.
PG2 may be assigned to any one of the 15 available Presets.
For page 1 and 2 contact wiring, see Doorbell Wiring Example
below using a 12VDC, 600mA power supply with a 30Ω,
5Watt Resistor.
Doorbell Wiring Example*
The contacts, Page 1 and Page 2, require a 12VDC power
supply. The example below illustrates, in a very simplistic way,
how Page 1 could be wired to a lighted doorbell to enable
auto-paging. This example bypasses the doorbell’s built-in
chimes. The P1 screw terminal connects to the 12VDC power
supply and the doorbell button. The Cscrew terminal connects
to the doorbell button and the 30Ω, 5Watt Resistor. The
other end of the resistor connects to the negative or common
side of the 12VDC power supply, as illustrated.
* NOTE: This example assumes new construction and requires
the door bell button, but does not require the traditional
doorbell chime and AC power supply. If an existing door bell
system is in place, the electromagnetic relay of the chime
replaces the 30Ωresistor and the AC transformer replaces the
12VDC, 600mA power supply.
Page 1 Wiring Example
A second doorbell can be attached to P2 following the same
procedure.

850D-DA Digital Distributed Audio Amplifier
Installation Manual 41316 / 1308134-A © 2011 Page 9
Control
The 850D-DA is controlled using the Vantage InFusion
controller over the Ethernet Bus. Connect the 850D-DA to the
local area network using a standard Ethernet patch cable.
Control from InFusion includes TPT touchscreens, portable
mobile devices connected to the local network, and other
wired devices on the InFusion System. NOTE: USB, RS232 and
IR control means are also available for third-party control or
testing.
Source Equipment
Sources 1 – 8: The 850D-DA amplifier has eight stereo RCA
audio inputs for connecting to source
equipment. These eight channels also feature
coax digital (SPDIF) inputs. Vantage
recommends using the digital inputs
whenever possible.1
1
NOTE: Sources 1-8 can accept two physical
connections from the same source when the
source has both analog and SPDIF outputs
as in many Blu-ray players. Depending on
the media being played, the signal may be
analog or digital. The 850D-DA will
automatically use SPDIF instead of analog
when the audio signal is digital.
Sources 9 – 12: There are four additional Digital only input
channels featuring coax (SPDIF) or Optical
connections.
Any output zone may select any of the connected sources. For
example, classical music may be playing in the lounge, while
nature sounds are playing in the Study.
All eight zones or stacked zones may be assigned to the same
source, or any combination of zones may be assigned to the
same source. Only one source may be connected to one
source input.
Source Onboard MediaPlayer:
Vantage’s 850D-DA has an onboard digital media source, via
the local Ethernet connection, adding the ability to stream
most, 1 or 2 channel files at ≤48kHz, network based audio
through the 850D-DA’s stereo, multi-zone system.
On Source Unit 1, the MediaPlayer Source has the ability to be
linked and buffering through multiple 850D-DA units playing,
synchronized, across each unit’s zones assigned to source 12.
Please see Section 6 and Section 8 for additional detail.
The onboard MediaPlayer (streaming network) source via
the Ethernet connection is a streamed source comprised of
sound files which are not compressed or changed in
quality by streaming over the local network.
oThis source uses a network storage device or similar
connected music source to play media files from
storage devices like the Vantage DMM or a NAS drive,
etc.
oSupported File Types: Ogg Vorbis, MP3, MP1/MP2,
MPEG4, HE-AAC v2, WAV and FLAC.
NOTE: The onboard MediaPlayer supports audio files with 1
or 2 channels and a sample rate of ≤48kHz.
Speakers
Speakers in each zone are connected to the amplifier by
"Home Run" speaker cables. Please see SECTION 1 - Quick
Install Overview, for recommended speaker wire.
Preamplifier Zone Outputs
Output zones 7 and 8 are line-level outputs. These preamplifier
output zones are completely independent of the digital
amplifier zones and of each other. These may be used for
locations where a higher or lower power amplifier / speaker
would be required. A third party power amplifier is required to
power these zones to speakers. See cautionary information
below.
Linking Preamplified Z7 or Z8 With Amplified Zones Z1 – Z6
Over amplification may damage third party
equipment. Employ caution using line-level outputs
to third party amplified equipment. Test equipment
connected to either zone 7 or zone 8 line-level
outputs to prevent over amplification. Due to varying gains of
third party amplifiers attached to Z7 or Z8, it is recommended
that the attached equipment have independent
attenuation/volume control. This can help the installer set a
trimmed level so the third party equipment is able to handle
either line-level Zones 7 or 8 when set to their maximum
output.
It is also possible to set the Max Volume level of zone 7 or
zone 8; this also helps prevent over amplification of the
attached equipment. Please note when linking volume, the Max
Volume level of each zone in the link is still enforced. For
example if zone 4 and zone 7 are linked including volume, and
the Max Volume of zone 4 is set to 100% and the Max Volume
of zone 7 is set to 50%, raising the linked volume control to full
on will result in zone 4 being at level 100% and zone 7 being at
level 50%. This is another way to help minimize potential
damage if the attached equipment cannot handle the line
level’s maximum output.
Summary
A preamplifier zone may be linked to one of the digital
amplifier zones or have an independent connection to a third-
party amplifier. This provides a line level output to another
speaker source, such as a subwoofer, as in the example on
page 7. The preamplifier zone and the amplified zone are
linked through the Link Zone command, allowing the two
zones to share the same source, and have a single volume
control or separate volume controls, etc.

Linking Multiple 850D-DA Amplifiers
Link multiple 850D-DA units to add additional audio zones within a project. When linking the 850D-DA, connect each unit via the
expansion bus using standard Ethernet patch cables. Each 850D-DA must have its own dedicated Ethernet Bus connection to the
local network as illustrated. The source equipment’s audio outputs are connected to the first 850D-DA unit in the stack. This is known
as the source unit. Audio signals are buffered and sent to the next amplifier in the stack via the SPDIF out to the SPDIF in using RCA
type connectors. The maximum number of 850D-DA amplifiers in a multiple unit configuration is nine (9). This allows 72 zones of
stereo audio.

The Vantage 850D-DA amplifier has a 2.4” LCD touch panel color display used for initial zone settings, system settings, trouble
shooting, and local control of the unit. The screens are intuitive and can be learned fairly quickly. Use the front screen interface for
stand-alone systems only; use Design Center for all setup and programming, with the exception of Lock-out mode. The touchscreen is
simply a tool*for local control, information, etc., of the 850D-DA amplifier.
*Please Note: Anything that can be managed from the front panel touchscreen should be managed
from Design Center software and the InFusion system via programmed tasks.
After 2 minutes of inactivity the LCD dims to 50% brightness, after a further 15 minutes it turns off. If the screen is off, the first touch
will restore the LCD to full brightness, enabling touch control.
