Installation 3
3:1.Location
The intended use of GTA series amplifiers is in a rack
only. The AC mains wirings of the units must be connected
to a terminal box provided with a properly breaker (refer
to §3:4.AC Mains supply for more details). It is not allowed
to connect the GTA series AC mains connection directly to
the power distribution system. For North America market
we recommend to use an approved UL/CSA cable (i.e. ST
600Vac 105°C 5x13AWG).
In order to limit the risk of mechanical damages, the
amplifiers must be fixed to the rack using both frontal and
rear mounting brackets. We recommend to use eight M6 or
12-24 UNC-2B screws for threaded holes or cage nuts.
Install this amplifier as far as possible from radio tuners
and TV sets. An amplifier installed in close proximity of such
equipment may experience noise or generic performance
degradation. Placing and using the amplifier for long periods
of time on heat generating sources will affect its performance.
Avoid placing the amplifier on heat generating sources.
This device must be powered exclusively by
earth connected mains sockets in electrical
networks compliant to the IEC 364 or similar rules.
Since the main power switch on this unit does not provide
a complete insulation of the equipment from the main power,
you must disconnect the main power source to turn off all
power.
3:2.Cooling
Install the amplifier in a well-ventilated location: the
ventilation openings must not be impeded by any item such
as newspapers, tablecloths, curtains, etc; keep a distance of
at least 50 cm from the front and rear ventilation openings
of the amplifier.
All Outline amplifiers implement a forced-air cooling
system to maintain low and constant operating tempera-
tures. Drawn by the internal fans, air enters from the front
panel and is forced over all components, exiting at the back
of the amplifier.
The amplifier’s cooling system features “intelligent”
variable-speed DC fans which are controlled by the heatsink
temperature sensing circuits: the fans speed will increase
only when the temperature detected by the sensors rises
over carefully predetermined values. This ensures that fan
noise and internal dust accumulation are kept to a strict
minimum.
Should however the amplifier be subject to an extreme
thermal load, the fan will force a very large volume of air
through the heat sink. In the extremely rare event that the
amplifier should dangerously overheat, sensing circuits
shut down all channels until the amplifier cools down to a
safe operating temperature. Normal operation is resumed
automatically without the need for user intervention.
GTA series amplifiers can be stacked one on top of the
other due to the efficient cooling system they are equipped
with.
There is however a safety limit to be observed: in case a
rack with closed back panels is used, leave one rack unit empty
every four installed amplifiers to guarantee adequate air flow
(see Panel G, p. 6).
3:3.Cleaning
Always use a dry cloth for cleaning the chassis and the
front panel. Air filter cleaning should be scheduled according
to the dust levels in the amplifier’s operating environment.
Disconnect the AC mains source before
attempting to clean any part of the amplier
In order to clean the vent filters you need to remove the
front cover: never attempt to open any other part of the unit.
By means of a metric hex key #6, unscrew the two screws
located on the left and right sides of the front panel, (see FIG.
1) gently lift the cover and remove the filter. You may use
compressed air to remove the dust from filters, or wash it
with clean water: in the latter case ensure that the filter is
dry before reassembly.
3:4.AC mains supply
GTA series amplifiers offer worldwide AC acceptance and
direct connection to any regional power line configuration.
The power supply is now suitable to single-phase, two-phase
or three-phase operation from 90 VAC up to 464 VAC without
need of manual selection: true three-phase load balancing
is directly achievable by the unit without any complex load
assignment in the power distribution system design.
AC mains connection is provided by means of the eu-
roblock Phoenix PC 5/5-STF1-7,62 flying plug (Phoenix prod-
uct ID 1777862). Proper assembly of the AC mains conductors
to the flying plug must respect the power line configuration.
Take care to connect any and all the five contacts of the
flying plug to the power cords according to the configuration
showed in Panel K, L, M at p. 9 and p. 10. In order to
guarantee the proper connection we recommend to use an
approved UL/CSA cable (i.e. ST 600Vac 105°C 5x13AWG).

3 Provide a sectioning breaker between the
mains connections and the amplier.
The proper device to use depends on mains con-
figuration; for GTA Otto Outline suggests:
X single-phase AC (P+N+E): 32 A rating, C or D curve, 10 kA;
X three-phase AC (3P+N+E): 4x16 A rating, C or D curve, 10 kA.
For GTA Quattro Outline suggests:
X single-phase AC (P+N+E): 16 A rating, C or D curve, 10 kA;
X three-phase AC (3P+N+E): 4x10 A rating, C or D curve, 10 kA.
NOTE: The pictures and instructions on AC wiring refer to the
European CENELEC standards April 2004 (IEC 60446) color
code for conductor identification (see TAB. 1).

TAB. 1: Color code for conductor idencaon.
AC mains connections must be performed
only by professional or qualied personnel
according to local electrical authoritie guidelines.
3:4.1.Three-phase electric power
Each single conductor must be secured to the
PC 5/5-STF1-7,62 flying plug as shown in Panel K, p. 9. In
some instances neutral connection may lack: on three-phase
systems neutral connection is not even necessary given the
capability of the GTA series to work in delta connection.
3:4.2.Two-phase electric power
Balanced two-phase AC mains in the configura-
tions 2P+E without neutral must be secured to the
PC 5/5-STF1-7,62 flying plug as shown in Panel M, p. 10.
Take care to double the phase wires at the connecting ter-
minals of the sectioning breaker in order to guarantee the
proper conduction gauge.
3:4.3.Single-phase electric power
P+N+E, unbalanced single-phase with neutral is the
usual configuration for signle-phase AC mains; wiring must
be configured as shown in Panel L, p. 9. Take care to dou-
ble the phase and neutral wires at the connecting terminals
of the sectioning breaker in order to guarantee the proper
conduction gauge.
3:5.Precautions regarding in-
stallation

Connections 5
Make sure the power switch is off before attempting to
make any input or output connections.
By using good quality input and speaker cables, the like-
lihood of erratic signal behavior is reduced to a minimum.
Whether you make them or buy them, look for good quality
wires, connectors and soldering techniques.
5:1.Signal grounding
There is no ground switch or terminal on the GTA series
amplifiers. All shield terminals of input connections are
directly connected to the chassis. This means that the unit’s
signal grounding system is automatic. In order to limit hum
and/or interference entering the signal path, use balanced
input connections.
In the interests of safety, the unit MUST always operate
with electrical safety earth connected to the chassis via the
dedicated Protective Earth wire.
5:2.Analog audio input con-
nections
Analog input is provided by means of Neutrik XLR female
connectors, one per channel input. Signal polarity of analog
input connections is shown in Panel H, p. 8.
5:3.Digital audio input con-
nections
Digital input is supported via AES3 (AES/EBU) and
Dante™ standard protocols in Dante equipped devices.
AES3 connectors are Neutrik XLR female, one per chan-
nel pair. The AES3 connection carries a channel pair through
a 110 Ω nominal impedance wire in the form of a balanced
(differential) digital signal: in AES3 XLR connectors the
identification of hot and cold pins is not an issue; take care
to never tie pin 2 or pin 3 (balanced signals) to pin 1 (ground).
Avoid the use of microphone cables in AES connections: im-
pedance mismatch can result in signal reflections and jitter,
causing bit errors at the receiver.
In Dante equipped devices, Dante connectivity is sup-
ported via two Neutrik etherCON ports located on the
rightmost side of the GTA Otto and GTA Quattro rear panels.
Fast Ethernet (IEEE 802.3u, 100 Mbit/s) and Gigabit Ethernet
(IEEE 802.3ab, 1 Gbit/s) network protocols are supported;
Cat5e or Cat6 standard UTP twisted pair cables shall be
used for connections up to 100 meters (328 ft).
Ethernet cabling must comply to TIA/EIA-568-B and adopt
the T568B scheme pinout, as shown in Panel I, p. 8.
5:4.Output connections
CLASS3
WIRING
CLASS 3 WIRING
Output terminals are hazardous: wiring connection
to these terminals require installation by an in-
structed person and the use of ready made leads. Take care
to secure the output terminals before switching the device
on.
Single-ended and bridge-tied loudspeaker connections
are supported as shown in Panel J, p. 8.
5:5.Ethernet connections
GTA series amplifier platforms can be remotely con-
trolled via an Ethernet connection through a personal com-
puter and Powersoft ArmoníaPlus software.
Outline recommends the use of Ethernet Cat5 straight
through – patch – cables with pin/pair assignments TIA/EIA-
568-B, i.e. T568B, as shown in Panel I, p. 8.

Outline GTA series amplifier platforms embed a com-
plete digital audio signal management system based on
ARM Cortex A-8 processor and TI C6000 DSP platform.
This impressive on-board computing capacity is driven by a
dedicated software environment.
Sebbene l’aggiornamento viene normalmente eseguito
direttamente da ArmoníaPlus, in caso di necessità è pos-
sibile eseguirlo tramite la procedura descritta sotto.
Prima di tutto, contattare Outline (o il proprio distribu-
tore) per farsi dare il file che avrà il nome
update-version#-model.bin
(e.g. update-v1.5.0.6-GTA Quattro.bin); in order to update the
software of your GTA series amplifier platform you must store
the software update file into a USB key and follow these steps:
1. Switch the amplifier on and wait for the completion of
the boot sequence.
2. Plug the USB key with the software update file into the
USB port on the front panel of the amplifier.
3. Keep pressed the rightmost pushbutton (Armonía
callback) until the second beep is emitted and the LEDs
start blinking.
4. Wait until the amplifier restarts and all front LEDs turn
solid blue.

Networking 8
GTA series amplifier platforms support linear daisy-
chain, star and loop network topologies; in a daisy-chained
network the PC with ArmoníaPlus must always be at one
end of the chain.
Be aware that daisy-chaining does not guarantee reli-
ability in production environment, since any fault may yield
to network sectioning and loss of system control.
When efficiency and reliability are paramount, a redun-
dant network topology is advisable. In order to exploit the
Dante features, only star and open daisy-chain network
topology are allowed.
8:1.IP addressing
Factory default network settings are DHCP/AutoIP, in
order for the amplifier platform to self-configure when con-
nected to an existing LAN or PC. Fixed IP policy can also be
adopted and configured through ArmoníaPlus.
If a DHCP server is not active within the network, the
amplifier platform initiates a stateless address auto-con-
figuration (i.e. Zero-configuration networking methodology
– Zeroconf): it self-assigns a local numeric network address
(of the type 169.254.x.y – 172.31.*.* for the secondary network
if present – with a subnet mask 255.255.0.0) and automati-
cally distributes and resolves the hostnames of networked
devices. For setting a static IP address, please refer to the
ArmoníaPlus user guide.
8:1.1.IP Addressing troubleshooting
When connecting the GTA series amplifier to a network
environment it may happen that ArmoníaPlus does not dis-
cover or import the amplifier.
Usually this is a problem of IP addressing: both Armonia
and the GTA series amplifier must belong to the same sub-
net. If a DHCP server is present in the network and a GTA
series amplifier platform is in AUTO IP, networking may
become unstable.
As a rule of thumb, turn the DHCP server
on before connecting the ampliers.
IP addressing of a GTA series amplifier is established
during the bootstrap: when the GTA series amplifier plat-
form discovers a DHCP server in the network during the
startup, it negotiates the networking parameters. If the GTA
series amplifier platform does not reveal a DHCP server
in the network during the startup, it sets itself in AUTO IP
mode.
8:2.Dante™networking
The Dante GTA series amplifier platforms support Dante
redundant networking via the two etherCON ports on the
rear panel:
X Primary/ETH1 is the Primary network port;
X Secondary/ETH2 is the Secondary network port.
Dante connectivity is always supported on the Primary/
ETH1 Gigabit Ethernet port; the Secondary/ETH2 Gigabit
Ethernet port offers continuity of operation when a parallel
redundant network is established.
In order to implement a Dante network, a computer run-
ning Dante Controller has to be used. Dante Controller is a
software application that manages devices in the network.
GTA series amplifier platforms are automatically discovered
and displayed in Dante Controller with the default identifier
MODELNAME-SERIAL (e.g. GTA Otto-71520).
Dante networks will almost always require at least one
network switch. Redundant infrastructures may require mul-
tiple switches. For maximum reliability, network switch shall:
X be Rated for Gigabit Ethernet;
X be Non-blocking;
X have Quality of Service (QoS) with at least four queues;
X have Diffserv (DSCP) QoS with strict priority;
X have EEE (Energy efficient ethernet) switched off.
For detailed information on setting up a switch, please
refer to the manufacturer’s documentation.
8:2.1.Redundant network configura-
tion
Dante Redundancy can be set-up and used between any
supporting Dante-enabled audio equipment: it works by us-
ing two completely independent and separate networks, the
Primary Network and the Secondary Network.
To setup and use Dante Redundancy, connect the GTA
series amplifier platform and other redundant Dante-
enabled audio equipment using duplicate Gigabit switches
and Ethernet cables. Connect your computer running Dante
Virtual Soundcard and Dante Controller, and other non-
redundant Dante-enabled audio equipment to the Primary
Network.
The primary and secondary networks MUST NOT be
interconnected at any point. Make sure any computer is set
to automatically configure its IP address.

ArmoníaPlus 9
9:1.Signal routing and DSP ar-
chitecture
Signal processing on Outline GTA series amplifier plat-
forms accomplishes multiple functions that affect the audio
signal before power amplification. The main adjustments
include gain, polarity, delay, limiting and signal equalization;
some processing functions are related only to particular
stages, such as limiting and damping control that are imple-
mented in the output section only, or input priority assign-
ment available in the input section.
The processing architecture is composed of six sections:
X Input source selection. The input section allows you
to manage input gain and delay of analog and digital
sources, in order to compensate transmission latency
ArmoníaPlus is the default configuring interface that
allows system setting and customization of the GTA series
amplifier platforms.
ArmoníaPlus can be installed on a PC running Windows
(XP SP3 and higher). ArmoníaPlus is available for free from
the Armonía website, where a startup guide and in depth
tutorials are also provided: hps://armonia.powerso.it/
Once you’ve installed ArmoníaPlus, it is necessary to
download the GTA plug-in from Armonía Marketplace.
GTA series amplifier platforms can be connected to a PC
running ArmoníaPlus through a Fast Ethernet connection.
In order to start remote operation, the amplifier must be
added into the ArmoníaPlus Workspace. Add the amplifier
by selecting the family and model.
The GTA series amplifier must then be matched by click-
ing on the Match section of the workspace, and then by click-
ing on “Discovery” to reveal any device which is available on
the network.
The callback button – located rightmost on the front
panel of the amplifier – allows you to highlight the amplifier
in the discovery panel.
9:2.Purposed workflow
Once the loudspeaker layout has been defined, we
suggest a bottom-up configuration procedure that starts
from the configuration of the transducers layout and raises
toward the input selection and the definition of the backup
policy.
Shortly, the main steps to follow are:
1. Load the loudspeaker presets or manually configure
the loudspeaker layout (grouping output channels,
crossovering, limiting, speaker processing, etc.).
2. Define the routing path and the levels of the signals
from the input channels to the active output channels
(matrix).
3. Select the signal source from the input connections
and define the backup policy (input source selection).
and levels. Furthermore, the GTA series implements
a backup policy aimed to improve reliability against
signal fault. By assigning a bus priority to the four
different input sources – analog, AES3 and two Dante
streams – per channel, the system is able to automati-
cally switch to a reliable input connection in case of any
signal fault.
X Matrix. The innovative routing engine of GTA series
allows any input to be routed to any output. The Matrix
implements a non-Boolean routing architecture allow-
ing free channel assignment and level adjustment.
X Advanced processing. This allows you to optimize
levels and shape the sound of the input signals. Gain
and polarity adjustment, asymmetric raised-cosine
full parametric filters, delay and mute are available on
each channel routed to the speaker section.
X Speaker equalization. Designed to manage the configu-
ration presets for multi-way systems, it implements
FIR and IIR full parametric filters.
X Speaker routing. Once properly grouped, the output
channels are presented to the matrix as speakers – a
single row representing a speaker (actually group of
ways) – allowing a high grade of granularity in signal
processing.
X Output processing. This allows fine-tuning of output
signals, aiming to optimize power delivering and loud-
speaker performance. It provides gain and polarity
adjustment, IIR and FIR full parametric filters, delay,
mute, limiting and damping control on each output
channel.
