4 Installation
4.1 Location
The intended use of Bias Q5 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 Bias Q5 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 600 Vac 105°C 5 x 13 AWG).
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 recommends 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 aect its performance.
Avoid placing the amplifier on heat generating sources.
4.2 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 Void amplifiers implement a forced-air cooling system to
maintain low and constant operating temperatures. 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.
Bias Q5 amplifiers can be stacked one on top of the other
due to the ecient 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 E, p. 6).
4.3 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 amplifier
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 figure 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.
4.4 AC mains supply
Bias Q5 amplifiers oers worldwide AC acceptance
and direct connection to any regional power line
configuration. Void’s legendarily reliable 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 euroblock
Phoenix PC 5/5-STF1-7,62 flying plug (Phoenix product 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 I, J, K at p. 8 and p. 9. In order to guarantee
the proper connection we recommend to use an approved
UL/CSA cable (i.e. ST 600Vac 105°C 5 x 13 AWG).
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 o all power.

Provide a sectioning breaker between the
mains connections and the amplifier.
The proper device to use depends on mains configuration;
for Bias Q5 Void suggests:
• single-phase AC (P+N+E): 16 A rating, C or D curve, 10 kA;
• three-phase AC (3P+N+E): 4 x 10 A rating, C or D curve, 10 kA.
NOTE: The pictures and instructions about AC wiring refer
to the European CENELEC standards April 2004 (IEC 60446)
color code for conductor identification (see table 1).

to local electrical authoritie guidelines.
4.4.1 Three-phase electric power
Each single conductor must be secured to the
PC 5/5-STF1-7,62 flying plug as shown in Panel I, p. 8. In
some instances neutral connection may lack: on three-phase
systems neutral connection is not even necessary given
the capability of the Bias Q5 to work in delta connection.
4.4.2 Two-phase electric power
Balanced two-phase AC mains in the configurations 2P+E
without neutral must be secured to the PC 5/5-STF1-7,62
flying plug as shown in Panel K, p. 9. Take care to double the
phase wires at the connecting terminals of the sectioning
breaker in order to guarantee the proper conduction gauge.
4.4.3 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 J, p. 8. Take
care to double the phase and neutral wires at the
connecting terminals of the sectioning breaker in
order to guarantee the proper conduction gauge.
4.5 Precautions regarding installation
WARNING: TO PREVENT FIRE OR ELECTRIC SHOCK
• This device must be powered exclusively by earth
connected mains sockets in electrical networks
compliant to the IEC 364 or similar rules.

6 Connections
Make sure the power switch is o before attempting
to make any input or output connections.
By using good quality input and speaker cables, the
likelihood 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.
6.1 Signal grounding
There is no ground switch or terminal on the Bias Q5
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.
6.2 Analog audio input connections
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 F, p. 6.
6.3 Digital audio input connections
Digital input is supported via AES3 (AES/EBU).
AES3 connectors are Neutrik XLR female, one per channel
pair. The AES3 connection carries a channel pair through a
110 Ωnominal impedance wire in the form of a balanced
(dierential) 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: impedance mismatch can result in signal
reflections and jitter, causing bit errors at the receiver.
Ethernet cabling must comply to TIA/EIA-568-B and adopt
the T568B scheme pinout, as shown in Panel G, p. 6.
6.4 Output connections
CLASS3
WIRING
CLASS 3 WIRING
Output terminals are hazardous: wiring connection
to these terminals require installation by an instructed
person and the use of ready made leads. Take care to
secure the output terminals before switching the device on.

chained network the PC with Armonía Pro Audio
Suite must always be at one end of the chain.
Be aware that daisy-chaining does not guarantee reliability
in production environment, since any fault may yield
to network sectioning and loss of system control.
When eciency and reliability are paramount, a
redundant 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 connected
to an existing LAN or PC. Fixed IP policy can also be
adopted and configured through Armonía Pro Audio Suite.
If a DHCP server is not active within the network, the
amplifier platform initiates a stateless address auto-
configuration (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 automatically
distributes and resolves the hostnames of networked
devices. For setting a static IP address, please refer
to the Armonía Pro Audio Suite user guide.
8.1.1 IP addressing troubleshooting
When connecting the Bias Q5 to a network
environment it may happen that Armonía Pro Audio
Suite does not discover or import the amplifier.
Usually this is a problem of IP addressing: both Armonia and
the Bias Q5 must belong to the same subnet. If a DHCP
server is present on the network and a Bias Q5 amplifier
platform is in AUTO IP, networking may become unstable.
As a rule of thumb, turn the DHCP server
on before connecting the amplifiers.
IP addressing of a Bias Q5 amplifier is established during
the bootstrap: when the Bias Q5 amplifier platform
discovers a DHCP server on the network during the startup,
it negotiates the networking parameters. If the Bias Q5
amplifier platform does not reveal a DHCP server on the
network during the startup, it set itself in AUTO IP mode.

9 Armonía Pro Audio Suite
Armonía Pro Audio Suite is the default configuring
interface that allows system setting and customization
of the Bias Q5 amplifier platforms.
Armonía can be installed on a PC running
Windows (XP SP3 and higher). Download Armonía
Pro Audio Suite from the Armonía forum:
http://www.voidacoustics.com/void_uploads/Armonia.zip
Bias Q5 amplifier platforms can connect to the PC running
Armonía through a Fast Ethernet connection. In order to
start remote operation, the device must be discovered and
imported into the Armonía Workspace. Click on the Discover
button in the Remote entities windows, or select it from
the Model list and drag it into the Armonía Workspace.
The callback button – located rightmost on the front
panel of the amplifier – allows you to highlight the
presence of the amplifier into the Armonía Workspace.
Once connected to Armonía Pro Audio Suite, a double
click on the amplifier icon in the Workspace will open
the amplifier dashboard. Here it is possible to access
and configure all the features of the Bias Q5 platform.
9.1 Signal routing and DSP architecture
Signal processing on Void Bias Q5 amplifier platforms
accomplishes multiple functions that aect the
audio signal before power amplification. The main
adjustments include gain, polarity, delay, limiting and
signal equalization; some processing are related only to
particular stages, such as limiting and damping control
that are implemented on the output section only, or
input priority assignment available in the input section.
The processing architecture is composed of six sections:
• 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
and levels. Furthermore, the Bias Q5 implements a
backup policy aimed to improve reliability against
signal fault. By assigning a bus priority to the four
dierent input sources – analog and AES3 – per
channel, the system is able to automatically switch to
a reliable input connection in case of any signal fault.
• Matrix. The innovative routing engine of Bias Q5
allows any input to be routed to any output. The
Matrix implements a non-Boolean routing architecture
allowing free channel assignment and level adjustment.
• 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.
• Speaker equalization. Designed to manage the
configuration presets for multi-way systems, it
implements FIR and IIR full parametric filters.
• 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.
• Output processing. This allows fine-tuning of output
signals, aiming to optimize power delivering and
loudspeaker performance. It provides gain and polarity
adjustment, IIR and FIR full parametric filters, delay, mute,
limiting and damping control on each output channel.
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).
